Opinion: Ndi-Anambra: Now is the time to Unleash Uche Onyeigbo

Published

By Chuks Nwune

Uche Onyeigbo is that rare and special intelligence with which every Igbo predicts, discerns and decides. Uche Onyeigbo is the natural capacity of every Igbo to get it right and it has served them so well in business, relationship, academics, innovation and so on. This November, Uche Onyeigbo must serve Ndi Anambra in politics; it is time to put on Awụrụ Onyeigbo (our thinking cap).
In the upcoming election, we have four candidates to watch – Emmanuel Andy Ubah (APC), Patrick Ifeanyi Ubah (YPP), Charles Chukwuma Soludo (APGA) and Valentine Ozigbo (PDP). Given all we have been through as Nigerians in general and Ndịigbo in particular, this is no time for business as usual. We need to get down to this matter as business, knowing our stuff and investing correctly. It is only when we understand Anambra as business that we may get it right. In this business, we have five crucial considerations to make our investment worth the while, Age, Competence, Compassion, Capacity, Religion and Party. We also need only one disposition in making the consideration SINCERITY.

Age: Our candidates’ ages are as follows: Emmanuel Andy Ubah – 62, Patrick IfeanyiUbah – 49, Charles Chukwuma Soludo – 60 and Valentine Chineto Ozigbo – 50. It is not rocket science to know that productive age for humans is between 40 and 60 years, that’s why people retire at 60 (Nigeria’s 65, 70, 75 is the same lie and corruption for which things are not working). This means that two candidates (Emmanuel Andy Ubah and Charles Chukwuma Soludo) are, by their age, plunging into productive decline already, while two (Patrick Ifeanyi Ubah and Valentine Ozigbo) will still be in the productive age bracket in the next ten years. Therefore, Emmanuel Andy Ubah and Charles Chukwuma Soludo in sincerity should retire. Anambra needs a PRODUCTIVE governor. The incumbent is a case in point. In his early 60’s the task of governing the state already weighs him down and overwhelms his aging mind.
Competence: This can be measured with career path and achievements considering that we are choosing a GOVERNOR, in other words the Chief Executive Officer (CEO) of the state. In this criterion you can rate our candidates in this sequence: 1st – Valentine Ozigbo, 2nd – Patrick Ifeanyi Ubah, 3rd – Charles Chukwuma Soludo and 4th – Emmanuel Andy Ubah. Why? Valentine Ozigbo has been in the private sector and corporate sector all his life; a world class business man who knows the buttons to push and open the flood gates of thriving businesses for Ndi-Anambra. He rose in the ranks in his line of business, having only his records to speak for him; a smart and digital business mogul who easily connects with the younger generation rating his presence and followership on social media. He had no family member speaking for him or recommending him. His achievements and records endeared him to those who employed him for his resourcefulness. He has done this all his life with evidential success; he never scored less than excellent.

Patrick Ifeanyi Ubah has been in the private sector and corporate business; recently he became a senator of the Federal Republic. He has done well for himself and boasts of investment worth billions of Naira. He is an oil magnate and has connected to that very factor which has kept Nigeria impoverished – oil. He belongs to the Buhari school of thought that overrates oil and will find it difficult to understand and connect to emerging economic drivers.

Charles Chukwuma Soludo is a first class academic and a world class researcher. He has made an enviable mark in the academia which earned him several appointments especially becoming the Chief Economic Adviser to the Federal Government and the Governor of CBN. We all know how appointments happen. Check out his family connections and you will find the finest Anambra daughter Prof. Dora Akunyili, she was already a federal bigwig by the time of that appointment. Our erudite Professor will be his best as adviser and appointee.

Emmanuel Andy Ubah is the typical Abuja boy whose youthful days were spent in Aso Villa serving at the corridors of power; whose political influence has been overrated. He lost his senatorial seat to Patrick Ifeanyi Ubah who challenged him from an unpopular political party. That alone tells his popularity among his own people. There is no evidence of him doing any business or administrative work before venturing into politics. In this criterion, he is overtly and covertly wanting.

Compassion: This is ones capacity and ability to genuinely and sincerely connect to the situations and conditions of others with the internal and compelling will to make it better. Again you can rate our candidates in this sequence: 1st – Valentine Ozigbo, 2nd – Patrick Ifeanyi Ubah, 3rd – Charles Chukwuma Soludo and 4th – Emmanuel Andy Ubah. Why? In this criterion, it is important to differentiate compassion from philanthropy.

The philanthropy of all our candidates is not in question, though it can also be graded. Valentine Ozigbo is the typical Nwa Onyenkuzi for whom excellence is a starting point. Yet he grew up trained to connect to others; his followers are connected to him personally and he follows up on them like friends. At 50 he still plays with his childhood friends and connects with them like years have not passed and achievements are not on the table. He has commensurate emotional intelligence for which he has been a consummate leader and captain in the business world. His humility is palpable even in pictorial appearances. The person you see is the person he really, sincerely and genuinely is, has always been and will continue to be.

Patrick Ifeanyi Ubah is classic philanthropist who has invested resources in improving the lives of the poor and needy. He is the typical boss for whom abundance is the reason for reaching out to others. He is the proverbial Nwoke afọ ukwu who yields sustenance for his followers; they always await his ‘Doings’. He is trained in the Igbo competitive ethos and he understands the world as a challenge to be subdued, human beings that constitute that world are means not ends.

Charles Chukwuma Soludo is a good man whose very close contacts may not easily describe as compassionate. He is intelligent nevertheless not with the emotional reach required of a leader. Many among his followers are not connected to him as a person; most are party loyalists who are ready to gamble the next eight years to maintain party domination. These days he dances, smiles and dresses funny; a typical political gambit. The real man we had known is the same we will likely see in Agu-Awka, this man on the campaign trail is acting a script.

Emmanuel Andy Ubah is a typical cold manipulator who believes in the success of antics. His antecedents in politics show his disconnection with the people which he does not deem necessary. His followers look up to the APC federal magic and at worst the replication of the Imo state horrible polimathics that is ruining the state. Ndi-Anambra are smarter than that level of manipulation.

Capacity: Capacity has to do with qualification, energy and vision. Again you can rate our candidates in this sequence: 1st – Valentine Ozigbo, 2nd – Patrick Ifeanyi Ubah, 3rd – Charles Chukwuma Soludo and 4th – Emmanuel Andy Ubah.

Valentine Ozigbo has an overwhelming qualification both in paper and field work, he has proven energy and potential to remain so by age considerations. He has a super vision for the state; realistic and achievable goals. Patrick Ifeanyi Ubah has the basic qualification, proven energy and potential to remain so by age considerations. He has his vision for Anambra State but lacks the ‘how’ of achieving them.

Charles Chukwuma Soludo has an overwhelming qualification both in paper and field work, he lacks energy and potential to recoup energy going by age considerations. He has super vision for the state typical of a theorist which is better on paper. Emmanuel Andy Ubah has basic qualification both on paper and field work, he lacks energy and potential to recoup energy going by age considerations. He both lacks capacity for vision and does not present one for the state.

Religion: Here we are considering the capacity to cross the obvious denominational lines in the state and build healthy allies with others. Denominational politics for the right reasons is undeniable in the state. Therefore, it is an issue also to consider. Again you can rate our candidates in this sequence: 1st – Valentine Ozigbo, 2nd – Patrick Ifeanyi Ubah, 3rd – Charles Chukwuma Soludo and 4th – Emmanuel Andy Ubah.

Valentine Ozigbo is a Catholic who in practical ways lives out a robust Christianity that fosters fraternity of all Christians. His childhood friends have become pastors and even bishops in the Anglican denomination and they remain very close friends. In organizing Unusual Praise – the largest African Christian Worship event – he demonstrates capacity to bring together all Christians in one worship space; he can also do same in a work space. People from other denominations are going to vote for him massively. The hierarchy of the Catholic Church has eye on him but are not expressing it enough.

Patrick Ifeanyi Ubah is a Catholic and has numerous friends from other denominations. He has also extended his philanthropy to other denominations. It is important to note that these friendships are not faith-based; they are benefit-based. Given the Catholic domination of the state in the last sixteen years those friends are not likely to wade the storm with him.

Charles Chukwuma Soludo is a Catholic and his party gives him more advantage in the Catholic circle. Yet the Willy Obiano denominational politics places him in a disadvantage. The hierarchy of the Catholic Church may be canvassing for a sympathy vote for him, but Ndi-Anambra know more than investing wrongly this time around. He is incapacitated to build the bridge needed in the state at this time.

Emmanuel Andy Ubah is an Anglican and a faithful one at that. He is totally unpopular among Catholics and has earned himself some dint of suspicion among Anglicans because of his party and meddling with the Buhari administration. As would be expected, he has an ill-disposition towards Catholics and is poised to bring further divisions in the state. Some ruthless Anglicans are fronting him to deal with Catholics “in a language they will understand.”

Party: Here we are considering how the political party appeal to Nd-Anambra. In this Criterion, 1st – Charles Chukwuma Soludo, 2nd – Valentine Ozigbo, 3rd – Patrick Ifeanyi Ubah and 4th – Emmanuel Andy Ubah. It is important to note that there are no political parties in Nigeria, we only have political platforms. Candidates do not represent ideologies of a party; they foster personally crafted political solutions and look for a political platform through which they may likely express it.

Charles Chukwuma Soludo belongs to All Progressives Grand Alliance (APGA). It is the ruling party in Anambra State and has dominated the state for sixteen years. It is a party which has offered Ndi-Anambra a unique voice in the Nigerian political sphere and which had the promise of fulfilling the aspiration of Ndịigbo. It was Dim Chukwuemeka Odumegwu Ojukwu who animated APGA and found in Peter Obi the embodiment of the aspirations of Ndịigbo which he hoped one day to make a national reality. When Peter Obi left APGA, the party breathed its last. Today it suffers the decomposition of the proverbial fish from its head. Governor Willy Obiano saw to it that the requiem of APGA was well orchestrated and Charles Chukwuma Soludo saw no problem with that. In 2017, Charles Chukwuma Soludo, fostered the political jingle in reply to PDP’s Oseloka Obaze’s “It’s broken; let’s fix it”, Soludo contended “It’s not broken, why fix it”. If Charles Chukwuma Soludo says it’s broken now, then he either had lacked the vision to see that it really was broken by 2017 or he deliberately lied and deceived Ndi-Anambra by that mantra. If he says it’s not broken, then he is outrighly blind but more dangerously he is not coming with a fix. No Anambra person would vote for a continuation of the status quo.

Valentine Ozigbo belongs to the Peoples’ Democratic Party (PDP) which is the major opposition party in Nigeria. Therefore, it suffers the jab of the federal might. At the same time one could say that Ndi-Anambra prefers PDP to any other party and in the event that APGA has reneged on the confidence they had transferred to them from their former PDP affiliation, they are likely to revert to PDP. The party had produced two former governors (Chinwoke Mbadinuju and Chris Ngige), Peter Obi (a former governor and the best of all governors Anambra has ever had) is one of the foremost figures in PDP and has risen to be a Vice Presidential candidate of the party. The party has two seating senators from the state and three House of Rep members. Invariably, Anambra is a PDP state which had experimented the possible shift to APGA. The current administration has finally laid that experiment to rest.
Most importantly, Valentine Ozigbo is the fruit of Ojukwu’s political ideology and Most Rev. Albert Kanenechukwu Obiefuna’s political son. He embodies the worthy dreams of these two fallen heroes in very succinct ways. When he chose the jingle “Aka Chukwu di ya”, he may not know that his battle has been fought and won in the spirit land because of his connection to the aspirations of these great heroes. The spirit of Ndi-Anambra will always identify where their Akara aka lies.

Patrick Ifeanyi Ubah belongs to the Young Progressive Party (YPP). He gave the party its initial and ever entry into Anambra political lexicon. As a member of the party, he is a seating senator representing Anambra South Senatorial Zone. By these antecedents, YPP is a force in the Anambra politics. It is rated third by that right. Most importantly, neither the party nor its candidate is worth the political investment of Ndi-Anambra.

Emmanuel Andy Ubah belongs to All Progressives Congress. He had reneged from PDP some years ago and flags the wand of federal might; APC is the ruling political party at the centre. APC is horror for the Igbo sensibility and is regarded as the political face of terrorist Boko Haram among the locals. In as much as the Federal Government treats the political relegation of Ndi-Igbo with levity and gerrymander, APC cannot win any election in the Southeast except at the Supreme Court.

The choice before Ndi-Amabra is clear. No right-thinking business-inclined Anambra person would want to invest in waste or what we refer to as “Ahịa kụrụ akụ”. In the criteria we discussed above, the candidates will be preferred in this order 1st – Valentine Chineto Ozigbo, 2nd – Patrick Ifeanyi Ubah, 3rd – Charles Chukwuma Soludo and 4th – Emmanuel Andy Ubah. If our disposition is SINCERITY, then let our polls reflect Uche Onyeigbo by which we naturally invest rightly and profitably. Now is the time for serious business, let us keep sentiments aside and do the needful for the future of Ndi-Anambra in particular and Ndịigbo in general.

PDP Crisis: Illegal Factional Convention is a Direct Assault on Party Constitution and Democracy

Published

on

By

By Prince Adedipe Dauda Ewenla

The attention of party faithfuls and the general public has been drawn to the desperate and unconstitutional attempt by a faction within the Peoples Democratic Party to foist an illegal National Convention on the party in clear violation of its constitution and established democratic norms.

Let it be stated unequivocally: the Constitution of the PDP is clear, unambiguous, and binding on all members only a duly elected National Working Committee (NWC) has the constitutional authority to convene, approve, and conduct a National Convention.

This position is firmly grounded in the provisions of the PDP Constitution:

1. Section 31(3) clearly vests the power to summon and convene the National Convention in the appropriate constitutional organ of the party, which operates through the National Working Committee.

2. Section 29(2)(a) establishes the National Working Committee as the principal executive organ responsible for the day-to-day administration and decision-making of the party.

3. Section 47(1) affirms the supremacy of the party constitution, making it binding on all members and organs of the party without exception.

Flowing from these provisions, any gathering, meeting, or assembly convened outside this constitutional framework is illegal, null, void, and of no consequence, being ultra vires, null ab initio, and incapable of conferring any legal rights or obligations whatsoever.

The ongoing attempt by a faction reportedly aligned with the Minister of the Federal Capital Territory, Nyesom Wike, to organize a so-called convention through an imposed and illegitimate caretaker structure is nothing but a brazen assault on the rule of law, party supremacy, and internal democracy, and amounts to a clear case of constitutional subversion.

For the avoidance of doubt:
Individuals who have been suspended or expelled from the party lack the locus standi to act on its behalf.

Any caretaker arrangement not constitutionally backed by the elected organs of the party remains a nullity ab initio.
No faction, no matter how powerful, can override the supremacy of the party constitution.

Any purported action taken in furtherance of this illegality is void and liable to be set aside ex debito justitiae by any court of competent jurisdiction.

It is instructive that the Federal High Court and other competent courts have already taken judicial notice of these constitutional breaches by entertaining suits challenging the legality of the proposed convention. This alone is a clear warning that the entire process is fundamentally defective and cannot stand the test of law.

We therefore align firmly and unequivocally with the leadership direction and stabilizing efforts under Kabiru Turaki, whose commitment to constitutional order, due process, and party unity remains the only credible path forward for the PDP at this critical time.

The party cannot and must not be hijacked by individuals driven by personal ambition, vendetta politics, or external influence.

The survival of the PDP as a viable opposition platform depends on strict adherence to its constitution and respect for its legitimate structures.

We warn, in the strongest possible terms, that:

Any convention conducted outside the authority of a duly elected NWC will be resisted and rejected by loyal members of the party.

Any outcome from such an illegal exercise will be treated as void ab initio and will not be recognized within the party or before the Independent National Electoral Commission.

Those promoting this illegality are inviting avoidable chaos, multiplicity of suits, and grave political consequences for the PDP ahead of 2027.

This is not just about a convention this is about the soul, legality, and future of our great party.

I call on all genuine stakeholders to rise above factional manipulation and defend the constitution of the PDP with courage and clarity.

The rule of law must prevail. Fiat justitia ruat caelum. The constitution must stand. The PDP must not fall.

Intentional Progressive Leadership and Disciplined Security: Catalysts for Unlocking Possibilities

Published

on

By

By Tolulope Adegoke PhD

In an increasingly interconnected and volatile world, the twin forces of intentional progressive leadership and disciplined security stand as indispensable drivers of meaningful advancement. Intentional progressive leadership is characterized by deliberate, forward-thinking decision-making that prioritizes inclusive growth, innovation, accountability, and long-term societal transformation over short-term gains or entrenched interests. Disciplined security, in turn, refers to a professional, rule-of-law-based, human-centered approach to safeguarding citizens, institutions, and resources—one that integrates military, intelligence, law enforcement, and community engagement while upholding human rights and fostering trust. Together, these elements do not merely maintain stability; they actively unlock possibilities across three interconnected spheres: peoples (individuals and communities), corporates (businesses and organizations), and nation building (state institutions and societal cohesion).

This write-up examines their active roles, portrays the current realities as they stand in Nigeria, Africa, and the wider world, provides relevant global and regional examples, and offers practical, unbiased solutions. Drawing on established patterns of development, the analysis underscores that where these forces converge effectively, they generate exponential outcomes; where they falter, stagnation and fragility ensue. The goal is to present a balanced, evidence-informed perspective suitable for policymakers, business leaders, scholars, and development practitioners internationally.

Defining and Contextualizing the Core Elements

Intentional progressive leadership goes beyond charisma or authority. It demands strategic vision anchored in data, ethical governance, stakeholder inclusion, and adaptive resilience. Leaders in this mold invest in human capital, promote transparency, and align policies with sustainable development goals. Disciplined security complements this by creating the enabling environment of safety and predictability. It emphasizes professional training, intelligence-led operations, community policing, and the rule of law rather than militarization or repression. When these operate in synergy, they transform potential into tangible progress: educated citizens innovate, businesses thrive without fear, and nations build resilient institutions.

Active Roles in Delivering Possibilities for Peoples

For individuals and communities, intentional progressive leadership and disciplined security create pathways to dignity, opportunity, and empowerment. Progressive leaders prioritize education, healthcare, and skills development, viewing people as the primary asset. Disciplined security ensures freedom from fear, enabling daily pursuits of livelihood and aspiration.

In practice, this synergy fosters social mobility and cohesion. Progressive leadership invests in youth programs and vocational training, while disciplined security protects learning environments and public spaces. The result is reduced vulnerability to exploitation and increased civic participation.

Active Roles in Delivering Possibilities for Corporates

Corporations require stable operating environments to invest, innovate, and expand. Intentional progressive leadership enacts policies that ease business registration, combat corruption, and promote public-private partnerships. Disciplined security safeguards supply chains, intellectual property, and personnel against threats like extortion or sabotage.

This combination drives economic dynamism. Businesses flourish when leaders provide predictable regulations and when security forces respond swiftly to disruptions, allowing corporates to focus on value creation rather than risk mitigation.

Active Roles in Delivering Possibilities for Nation Building

At the national level, these elements are foundational to sovereignty, legitimacy, and prosperity. Progressive leadership builds inclusive institutions, diversifies economies, and integrates regional and global partnerships. Disciplined security preserves territorial integrity, deters external interference, and supports internal harmony.

Nation building succeeds when leadership fosters national identity and security architecture reinforces it through equitable protection and justice.

The Current Picture: Realities in Nigeria, Africa, and the Wider World

Nigeria exemplifies both promise and persistent hurdles. As Africa’s most populous nation and largest economy, it possesses immense human and natural potential. Yet, as of early 2026, security challenges remain acute: insurgency and banditry in the Northeast and Northwest, farmer-herder conflicts in the Middle Belt, kidnapping for ransom nationwide, and separatist tensions in the Southeast. These have displaced millions, stifled agriculture and commerce, and eroded public trust. Leadership under President Bola Tinubu has pursued reforms, including kinetic and non-kinetic counter-insurgency measures, the appointment of a new Chief of Defence Staff in late 2025 for better operational coherence, and emphasis on human capital development (HCD 2.0). Progress includes reported surrenders of insurgent affiliates and targeted infrastructure investments, yet gaps persist in governance coordination, community engagement, and addressing root causes such as poverty and youth unemployment.

Across Africa, the landscape is heterogeneous. Positive models include Rwanda, where post-genocide leadership under President Paul Kagame has combined visionary governance with disciplined security to achieve sustained growth, digital innovation, and regional stability. Botswana stands as another exemplar: decades of prudent, transparent leadership have turned diamond revenues into broad-based development while maintaining professional security institutions that uphold democratic norms. Ghana demonstrates democratic continuity with progressive economic policies and relatively effective security cooperation. Conversely, parts of the Sahel face coups, jihadist expansion, and governance fragility, highlighting how leadership vacuums and undisciplined security exacerbate cycles of instability.

Globally, the interplay is evident in success stories such as Singapore’s transformation under Lee Kuan Yew, where meritocratic leadership and disciplined, corruption-free security institutions propelled a resource-poor city-state into a high-income economy. South Korea’s post-war reconstruction similarly blended visionary leadership with security alliances and human capital focus. In contrast, nations experiencing leadership complacency or fragmented security—such as certain conflict zones in the Middle East or Latin America—illustrate stalled development and eroded possibilities.

These realities reveal a clear pattern: intentional progressive leadership and disciplined security are not luxuries but necessities. Their absence perpetuates underdevelopment; their presence catalyzes breakthroughs.

Relevant Examples Illustrating Essence and Impact

  • Rwanda: Post-1994 genocide, intentional leadership focused on reconciliation, education, and technology hubs, supported by disciplined security reforms that prioritized professional training and community policing. This has elevated Rwanda to one of Africa’s fastest-growing economies, attracting foreign investment and reducing poverty dramatically.
  • Botswana: Progressive leadership emphasized accountable resource management and anti-corruption measures, paired with a professional military and police force. The outcome is one of Africa’s most stable democracies and highest Human Development Indices.
  • Singapore: Lee Kuan Yew’s intentional policies built a merit-based civil service and rigorous, rule-based security apparatus. This created a safe, efficient environment that transformed the nation into a global financial and logistics hub.
  • Nigeria-specific: Initiatives like community-based security arrangements in some states, when aligned with progressive local leadership, have reduced localized banditry. Corporate examples include Lagos tech ecosystems thriving amid targeted security enhancements in business districts.

These cases justify the essence: deliberate leadership and disciplined security deliver measurable possibilities when integrated holistically.

Proffering Relevant Solutions: Pathways Forward Without Prejudice

Solutions must be context-specific yet universally applicable, emphasizing collaboration across stakeholders.

For Peoples (Individuals and Communities):

  • Nigeria and Africa: Scale up human capital programs like Nigeria’s HCD 2.0 through universal basic education, vocational training, and digital literacy, especially in rural and conflict-affected areas. Integrate community policing models that empower local vigilantes under professional oversight to build trust.
  • Wider World: Adopt inclusive social safety nets and mental health support in post-conflict settings. International partners can provide technical assistance for youth entrepreneurship funds.
  • Outcome: Reduced vulnerability and empowered citizens who contribute actively to development.

For Corporates:

  • Nigeria and Africa: Enact progressive policies such as streamlined business regulations, tax incentives for security technology investments, and public-private security partnerships (e.g., joint task forces for critical infrastructure). Encourage corporate social responsibility in community safety initiatives.
  • Wider World: Promote global standards like ISO security management systems and cross-border investment guarantees tied to stability metrics.
  • Outcome: Enhanced investor confidence, job creation, and innovation ecosystems.

For Nation Building:

  • Nigeria: Strengthen institutional reforms, including anti-corruption enforcement, judicial independence, and devolved security responsibilities (e.g., state police with federal safeguards). Foster inclusive national dialogues and leverage technology for intelligence sharing.
  • Africa: Enhance African Union mechanisms for peer review, joint peacekeeping, and economic integration to address transnational threats.
  • Wider World: Support multilateral frameworks that reward progressive governance with development aid and security cooperation, emphasizing capacity-building over external imposition.
  • Cross-cutting Measures: Invest in data-driven monitoring (e.g., peace indices), leadership training academies, and civil society engagement to ensure accountability.

Implementation requires political will, sustained funding, and adaptive evaluation. International standards—such as those from the World Bank’s governance indicators or the Institute for Economics and Peace—can guide benchmarking without external overreach.

Conclusion: A Call to Deliberate Action

Intentional progressive leadership and disciplined security are not abstract ideals but active agents that shape destinies. In Nigeria and across Africa, where challenges are pronounced yet potential is vast, their effective deployment can convert vulnerabilities into strengths. Globally, they offer proven blueprints for resilient, prosperous societies. The current picture, while marked by setbacks, also reveals pathways of hope through ongoing reforms and exemplary models. By embracing these forces with intentionality, stakeholders at all levels can deliver genuine possibilities—empowered peoples, thriving corporates, and cohesive nations. The imperative is clear: invest in people-centered leadership and professional security today to secure a more equitable and stable tomorrow. Through collaborative, evidence-based strategies, Nigeria, Africa, and the wider world can realize their full potential in an interdependent global order.

Characterisation of Biomass Feedstocks Relaxation Properties Using Visco Elastic Models

Published

on

By

By Dr. Aminu Owonikoko, PhD

Overview

This thesis investigates a deceptively simple but industrially important question: what happens to biomass materials when they are compressed and then allowed to relax? Biomass — such as woodchips, wheat straw, leafy residues, cotton seeds, and wood pellets — is a major renewable resource used for energy production and sustainable manufacturing. However, its physical behaviour during handling, storage, and processing is poorly understood. Unlike uniform materials such as sand or grain, biomass is irregular, springy, and unpredictable. This unpredictability leads to blockages, equipment failures, and inefficient energy use in biomass processing plants.

The research provides a scientific foundation for predicting how biomass behaves under pressure by combining controlled experiments with Visco elastic modelling. The work introduces a new method for extracting key model parameters, enabling more accurate and transparent predictions of biomass relaxation behaviour.

Why Biomass Behaviour Matters

Biomass supply chains involve several mechanical steps: compaction, transport, storage, and feeding into processing equipment. During these steps, biomass is often compressed. Once the pressure is removed, the material “relaxes” — it expands, shifts, and redistributes internal stresses. This relaxation affects:
• how much biomass can be stored
• how reliably it flows through hoppers and conveyors
• how much energy is required to process it
• the likelihood of blockages or equipment downtime

Understanding this behaviour is essential for designing efficient, reliable, and cost effective biomass systems.

Research Aim

The central aim of the thesis is to characterise the stress relaxation behaviour of five biomass feedstocks and to develop robust Visco elastic models that can predict this behaviour under different loading conditions.

Experimental Approach

Five biomass materials were selected due to their relevance in renewable energy and agricultural supply chains:
• Fuzzy cotton seeds
• Leafy biomass
• Wheat straw
• Woodchips
• Wood pellets

Each material was compressed using a Shimadzu MTS testing machine. After reaching a target stress level, the load was held constant while the material’s stress decay was recorded over time (typically 60, 120, and 180 seconds). These measurements captured both fast relaxation (immediate stress drop) and slow relaxation (longer term settling).

The experimental data revealed that each biomass type behaves differently, reflecting differences in structure, moisture content, particle shape, and internal bonding.
Modelling Approach

To interpret the experimental results, the thesis applies Visco elastic models — mathematical tools traditionally used to describe materials that behave partly like solids and partly like fluids. Two models were central:
1. Zener Model
– Captures both elastic and viscous behaviour
– Useful for materials with a clear fast relaxation component

2. Two Maxwell Elements Model
– Represents two relaxation processes simultaneously
– Ideal for materials with both fast and slow relaxation phases

A key contribution of the thesis is the development of a numerical and graphical method for estimating model parameters (such as relaxation time constants) without relying heavily on curve fitting software like MATLAB or OriginPro. This method improves transparency, reduces error, and makes the modelling approach more accessible to engineers.
Key Findings

1. Biomass Has Distinct Relaxation “Signatures”

Each biomass type exhibits a unique pattern of stress decay. For example:
• Wood pellets relax quickly and predictably.
• Leafy biomass relaxes slowly and irregularly.
• Wheat straw shows intermediate behaviour.
These signatures can be used to classify materials and predict their handling performance.

2. Fast and Slow Relaxation Are Mechanically Meaningful

The two Maxwell elements model successfully separates fast and slow relaxation processes. This distinction helps engineers understand how biomass responds immediately after compression versus how it settles over time.

3. New Parameter Extraction Method Improves Accuracy

The thesis introduces a novel approach for estimating relaxation time constants and stress components. This reduces dependence on automated curve fitting tools and provides more reliable model predictions.

4. Models Predict Real Behaviour Well

When applied to experimental data, both the Zener and two Maxwell models accurately reproduce the relaxation curves. This confirms that Visco elastic modelling is a powerful tool for biomass characterisation.

Practical Implications

The findings have direct relevance for industries that handle biomass:
• Improved equipment design: Better predictions of relaxation behaviour reduce blockages and mechanical failures.
• Optimised storage: Understanding how biomass settles helps determine safe and efficient storage densities.
• Reduced energy use: More predictable flow reduces the energy required for conveying and processing.
• Enhanced process reliability: Plants can operate more consistently with fewer interruptions.

Conclusion

This thesis provides a comprehensive experimental and theoretical framework for understanding biomass relaxation behaviour. By combining detailed measurements with improved Visco elastic modelling, it offers new insights into how biomass responds under pressure — insights that are essential for scaling up renewable energy and sustainable manufacturing.

The work advances both scientific understanding and practical engineering, contributing to the development of cleaner, more efficient biomass systems.
