My dear country men and women, please permit me to begin today by confessing that Nigeria is under distress. Its woes are most evident in the spate of armed violence and criminality ravaging the component parts. In fact, nothing explains this awry situation better than the apocalyptically volatile situation in the wider northern region.
The northeast is still under the Boko Haram scourge in spite of the counter-insurgency endeavors of the Governor Babagana Zulum’s administration. The north-central area has been afflicted by herdsmen militancy and ethno-religious conflicts, which has plunged the region into crisis. The northwestern region has recently been enmeshed in the rapid upsurge of rural banditry along its international frontiers as well as the forested interior.
But my concern today is particularly the Northwestern region of Nigeria where I come from. For about a decade, the region has been facing insecurity related crises ranging from armed-group violence to kidnappings and banditry, affecting inhabitants of Zamfara, Katsina and Sokoto states. Recently, Kaduna and Niger states have joined the fray, and appear to be the central hub of banditry in the entire country. Kano and Jigawa seems to be the only relatively peaceful states in the Northwest today.
Unfortunately, the Nigerian government’s response to the crises in the region has done little to alleviate the security concerns, and the situation appears as if bandits and criminals have overrun our country and effectively taken over its leadership. Any right-thinking Nigerian knows that this is the most burning issue for discourse, especially at a time when a religious scholar, Sheikh Ahmad Gumi, by his consistent questionable attitude and baseless ground, adds salt to festering wounds. Having watched his interviews a couple of times, his comments seem unacceptable. I am speaking as a Muslim, Northerner and partly a Fulani.
Nothing is more dangerous than politicizing issues that has to do with the security of the people; but, despite the red flags Gumi have manifested, Northern leaders have obviously done nothing, and what they are doing if at all they are, is not enough to restore sanity in the land. A flashback to some episodes that had happened recently, the efforts of the government so far (military operations and dialogue), and why such efforts are not sufficient enough would be the focus of my discussion today.
We could recall that the recent spate of banditry-related violence began in 2014 with cattle rustling activity, but the matter became worse in early 2016 when the bandits started killing local miners in Zamfara communities. However, the attacks now affect the entire North West region, especially the border areas with Niger. In what has become a recurring tragedy, not only have thousands been killed, but women have been raped, children have become orphans, villages have been sacked and destroyed, farm produce has been destroyed, property has been stolen, and civilians have been kidnapped for ransom. As a result of these, the affected states including Katsina, Kaduna, Sokoto, and Kebbi established a committee headed by Muhammad Abubakar, a former Inspector-General of Police in 2019. He estimated that between 2011 and 2019, 4,983 women were widowed, 25,050 children were orphaned, and more than 190,340 people were displaced in Zamfara due to armed banditry.
Kidnapping for ransom has become a particularly lucrative and attractive business to many in the North West region, especially among the many unemployed youths. Many residents lament how easily the armed banditry groups storm their communities in broad daylight to either rustle cattle or kidnap people. The kidnappers no longer have interested in kidnapping ordinary villagers, however. Rather, they realize that attacking schools and inter-state transportation routes brings in more money.
Apart from the recent attacks that happened till September, 2021, Terrorism Monitor has for example, recorded at least eight (8) mass kidnappings of school children and university students in the past six months, including: One, In December 2020, there was an attack on Government Science Secondary School students in Kankara, Katsina State, where over 300 students were abducted by a group of armed men on motorcycles. The state government insisted that nothing was paid for the release of the students, but some residents confirmed that 30 million naira was released to the bandits. The late Boko Haram leader Abubakar Shekau claimed his fighters in the North West region abducted the students, although the abductors had already contacted the state government on the issue of ransom payment before Shekau’s faction released an exclusive video from the bandits’ camp featuring the boys. Two, according to Daily Trust publication on January 6, 2021, there was a kidnapping of more than 317 schoolgirls in Jangebe, Zamfara State. This came just a week after a similar kidnapping incident. Three, on December 19, 2020, two days after the release of the Kankara schoolboys, bandits abducted over 80 Islamic school (Islamiyya) students in Dandume, Katsina State. The children were rescued after a vigilante group and volunteers intercepted them while they were trying to cross the forest.
Four, Armed bandits stormed the Federal College of Forestry Mechanization in Mando, Kaduna State in March 2021 and abducted 39 students. The bandits demanded 500 million naira ransom from the Kaduna State government, but after the governor, Nasir El-Rufai, failed to comply, they reached out to parents of the abducted students. The governor declared that no more payments of ransom would be made after the abduction and promised not to negotiate with any armed group. Three weeks after the abduction the kidnapped students were released in a negotiation facilitated by Shaykh Ahmad Gumi’s dialogue committee with support from former President Olusegun Obasanjo.
Five, In March 2021, an undisclosed number of primary school students in a village in Birnin Gwari, Kaduna State were abducted. A resident and father of one of the victims revealed that the children were rescued by vigilante groups a few days after the abduction. Six, similarly, on April 23, students of Greenfield University in Kaduna State were abducted by bandits who demanded a ransom of 800 million Nigerian naira. Five students were killed in captivity while 14 were released after a payment of ransom. Seven, on June 10th in the same vein, an armed group invaded Nuhu Bamalli Polytechnic in Zaria, Kaduna State. One student was killed and eight people, including lecturers and students, were abducted, which caused the school’s administrators to shut down academic activities immediately. Eight, one week after the Nuhu Bamalli abduction, on June 17, another 102 students of Federal Government College in Birnin Yawuri, Kebbi State were abducted. The governor chose not to negotiate with the abductors and one male and one female student were killed, while five others were rescued after the Nigerian forces operating under Hadarin Daji intercepted the abductors. More than 80 armed bandits were reported killed by the troops with support from Nigerian air force and more than 800 rustled cattle were recovered. However, approximately 95 students remained in the custody of the armed bandits in the forest while vigilantes and volunteers mobilized for another rescue mission.
It is clear that Nigerians are paying ransom to the kidnappers and banditry groups because they have seemingly lost interest and confidence in security intermediates. However, the paying of ransoms is motivating more bandits to join the kidnapping business even as government has remained clueless. Some have even accused the government of sponsoring insecurity indirectly by paying ransoms. According to this perspective, a government serious about tackling the issue would not pay any money to criminal armed groups in the form of ransom for kidnappings because it is an offence against citizens that require proactive and prompt security operatives to curb. Based on the aforementioned, the laxity of the government in restoring sanity in the affected places is obvious. You can imagine the hidden places of those bandits in the forests that extended through the length and breadth of northwest including Rugu, Kamara, Kunduma, and Sububu forests known to the government and all have since become strategic strongholds for banditry groups to carry out their attacks. They retire to those places and live peacefully and fearlessly after their operations. This is depressing to Nigerians.
In response to that however, Nigerian government has launched multiple military operations in the North West region to curtail the menace since 2019, including Operation Harbin Kunama and Exercise Sahel Sanity. The military operation, Exercise Sahel Sanity, headquartered at the Special Army Super Camp IV in Faskari, Katsina State, led to the killing of 220 bandits and the rescue of 642 kidnapped victims from captivity. The troops also destroyed 197 bandits’ enclaves, killed the notorious armed leader called “Dangote” of the eponymous “Dangote Triangle” in Katsina, and arrested 335 suspected bandits and 326 illegal miners in Kebbi, Kaduna, Niger, Zamfara and Katsina states. In July 2020 as gathered by media outlets including Premiumtimes.ng of July 3, 2020 and TheCable.ng of July 7, 2020, Mustapha Inuwa, the Secretary to the Katsina State Government, announced that his state had spent about 30 million Naira on an amnesty programme for repentant bandits and cattle rustlers before it collapsed. Inuwa further stated that the reason for the collapse of the peace deal was that the bandits kept reneging on agreements and betraying their promises to the government. However, based on my understanding, the efforts of Katsina State government solely depended on dialogue with the bandits which has since failed. The recent discovery of some bandits in Katsina State payroll is enough to inform some hidden fruitless agreement.
Moreover, Katsina and Zamfara governments also employed the services of non-state actors, like vigilante groups and Security Volunteers often called Yan Sakai, to curtail the conflict. Although they possess knowledgeable insights and understanding of the local conflict, they have their own disadvantage. For example, some of the vigilante members have seized on the opportunity stemming from the conflict to attack perceived enemies.
My other concern today is about the interference of the controversial Islamic scholar Sheikh Ahmad Gumi on the issue of banditry. He was recently reported to have said that military onslaught would worsen banditry in Nigeria. His utterances has caught my attention on several occasions. I sometimes wonder whether the Sheikh is conscious of the embarrassment he is causing the entire north. I see no reason why criminals should be protected or sympathize with. He even sometimes confer some sort of legitimacy on their nefarious activities. But my surprise is that no governor in the north has ever called him to order or pointed an accusing finger to him against the dangers surrounding most of his actions. Honestly, the intervention of Ahmad Gumi is only doing more harm than good to the country because of the belief in many quarters that he is colluding with the bandits. And that is a threat to the already weakly united Nigeria. The bandits are also seemingly encouraged by his actions. The criminals even requested the President to come and negotiate with them personally. I don’t know what type of negotiation apart from what Katsina and Zamfara states governors earlier considered. I must commend Nasir El-rufai’s in refusing any form of negotiation.
Regional banditry in North West Nigeria will be difficult to resolve if the government continues with its current strategy. In the first place, explosive population growth and climate change in Nigeria are exacerbating economic anxiety and fomenting lawlessness, especially in communities bordering Niger. Moreover, there is unchecked border crossings between herder tribes, as there is virtually no restriction on movements in these border areas. Anyone in Niger Republic can come to Nigeria, commit any crime, and go back to Niger.
Furthermore, corruption plays a significant role as some security agencies allegedly collect bribes from Nigeriens and grant them access to Nigeria without proper investigation. The suggestions of Kano state governor on how to arrive at a lasting solution must be considered. Our governors and stakeholders in their respective states, especially the religious leaders must work in synergy and stand united. They should also stand against Gumi and teach him that those criminals that invaded the north are mostly none-Nigerians, but used the advantage of porous borders and laxity of laws to invade the country. They came to Nigeria from different parts of West Africa, roaming dangerously and violently in and out of the country unchallenged.
Why then would Sheikh Gumi be protecting people that do not belong here on criminal matters? It is not surprising if our Southern counterparts accuses the Nigerian Fulani herders for causing troubles in the land, probably because they could not decipher. But the truth is, not all are Nigerians and our Northern leaders must as a matter of urgency do the needful.
I strongly support the anti-grazing law enforced by the Southwest governors, and I never consider their stand as an effort to humiliate the North. We cannot continue in the old ways in spite of several transformations the world has experienced in recent years.
Peace shall be restored in Northwest and other parts of the country.

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

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
3 days agoon
March 28, 2026By
Eric
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
3 days agoon
March 28, 2026By
Eric
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.
