Ninth Senate @3: Senator Adeola’s Impressive Scorecard

Published

on

By Kayode Odunaro

On June 11, 2019, the 9th Senate was inaugurated with the emergence of Senator Ahmad Lawan as President of the Senate. On June 11 this year, the Senate clocked 3 years with only about a year before the session expires. As it is, the remaining year of the four-year mandate will be spent mostly on electoral campaigns by candidates for various legislative and executive positions. It is therefore meet for a review of performances of legislators in the last three years. One senator with an enviable scorecard to show case effective representation as a legislator par excellence is Senator Solomon Adeola (APC, Lagos West)

In the three years that had elapsed in the 9th Senate, Senator Adeola sponsored and successfully introduced 14 Bills. Three of the bills have been successfully passed by the 9th Senate, one has passed Second Reading for public hearing while 10 have undergone first reading or in the process of listing for first reading in the crowded legislative time table of the Senate.

The passed bills are “A Bill to Provide for the Establishment of Federal University of Technology, Yaba and other matters, 2020” (SB.85), “A Bill to Provide for the Establishment of the Federal University of Technology, Ilaro (Est, etc), 2019” (SB. 84) and “A Bill for an Act to Provide for the Establishment of Nigeria French Language Village as an Inter University Centre for French Studies and other matters Connected therewith, 2020” (SB.483), These passed bills as well as those in the remaining in process of passage dwells on educational, constitutional and institutional development as well as human rights issues in Nigeria.

There is expectation that the three passed bills will be enacted into laws with concurrence of the House of Representatives and assent by the President before the end of the 9th Senate. Equally the NDCC Amendment bill by Senator Adeola that has passed Second reading will be passed to rightly include Lagos as an oil producing state. The senator as the chairman of Senate Committee on Finance fully contributed and was instrumental to the passage of three critical and unprecedented Executive Bills namely, the Finance Acts 2019, 2020 and 2021. These laws form a major aspect of funding the three Appropriation Acts of 2020, 2021 and now 2022. From all indications the laws are regarded as revolutionary as well as reformist in nature as they positively reform some of the nation’s financial legislations as well as bring such legislations to modern global standard.

In the area of oversight, the senator has successfully moved 8 motions that resulted in Senate Resolutions for which actions are being taken. The motions include that on Ijegun Pipeline Explosion; the motion on Abule-Ado, Amuwo-Odofin Explosion, the motion on Frequent Fire/Explosions in Lagos West Senatorial District, the motion to Reduce the Disparities between Lending and Deposit rates charged by commercial banks and other financial institutions and a commiseration motion for Senate to honour late Senator Munir Muse and another for late Senator Osinowo Adebayo. The two-term ranking senator also co-sponsored no less than 30 other passed motions that resulted in Senate Resolutions.

When COVID-19 pandemic broke out necessitating a prolonged lockdown, Senator Adeola reached out to indigent and vulnerable constituents for sustenance. At the peak of the lockdown of the COVID-19, he donated N50million which was shared among individuals, groups and communities during the extended period of lockdown. This was an unprecedented and unforeseen aspect of his representative function as nobody planned for a pandemic and its debilitating and destructive effects during campaign for offices.

In spite of the disruptive pandemic with negative global socio-economic effects, the senator, using his wealth of legislative experience delivered many dividends of democracy for his constituents in some critical areas that will serve not only many people but will be useful for many years ahead.

In the area of provision of portable water, he facilitated 6 major water works in form of solar powered boreholes and water treatment plants in six (6) LGAs namely; Ikeja, Ifako-Ijaiye, Agege, Oshodi-Isolo, Mushin and Alimosho in 2020. These self- sustaining water projects are located in population centres in the LGAs like markets and densely populated residential areas. He also personally constructed at least a normal borehole in each of the 28 LCDAs and similar number of public toilets spread across the senatorial district. Under the 2021 Budget he facilitated the construction of another 60 solarized boreholes across LGAs and LCDAs of Lagos West Senatorial District making a total of 94 of such water outlets.

Developing human resources in his district got serious attention from the senator as he facilitated the training of over 1000 of constituents in rural riverine communities of Lagos West in different aspects of Fish Production, Business, Feed Making and boat operation over a period of months. Each trained and certificated participant in a programme of “teach a man to fish” were equipped and giving grants to commence business. In addition, he facilitated the training of at least 8000 constituents in vocations such phone repairs, hair dressing, make up artistry, soap/detergent making and sanitizer making skills and entrepreneurship development with participants receiving start up equipment and cash grants. Market men and women are also included in the grants in his programme tagged “Okowo Yayi” meant to assist in shop rent payments and purchase of more stock to boost their trades. Similarly, he facilitated ICT Training for about 1000 unemployed graduates that were certificated internationally at the end of their training in Azure (Cloud Computing), Power BI (Data Analysis), Basic and Advance Excel (Data Analysis), Digital Marketing and Graphic Designs. Each of the participant got a modern laptop for their practice. Hopefully the training and certification will exit them from the unemployment market as these skills are in high demand in the ICT sector locally and internationally.

Similarly, with the realization that many teachers were not online/ICT compliant Senator Adeola facilitated a one-week training for teachers in the state where the rudiment of online teaching were taught to over 147 teachers with due certification. To complement this, he donated two (2) HP Computer laptops to the school authorities of 36 selected schools for the purpose of assisting in online teaching. Equally, he empowered 60 selected best students from secondary schools in Lagos West Senatorial District with computer laptops to encourage excellence.

For constituents desirous of establishment in the booming business of logistic and delivery, he gave out 185 motorcycles to constituents in each ward in the district in 2020. In 2021 he also empowered selected constituents with Block Molding Machines, Refrigerators, Sewing Machines, Grinding Machines, Hair Dryers, Clipper Sterilizers and Generators, Deep Freezers, Tricycles (Keke Napeps) and Vulcanizing Machines, a feat that was repeated at his 2022 edition of the empowerment programme, with the donation of all the above items and more like mini buses(Korope), ambulances, security vehicles and welding machines.

To address deficiencies in power supply the senator facilitated the procurement and installation of 28 units of 500 KVA Transformers which were distributed to communities across the 10 LGAs and LCDAs of the senatorial district. Similarly, he facilitated the provision of 180 poles solar panel street lights which were distributed to 20 major streets in Ojo, Badagry, Ajeromi-Ifelodun, Amuwo-Odofin, Ikeja, Alimosho, Mushin, Ifako Ijaiye, Oshodi-Isolo and Agege LGAs in 2020. In 2021, the distributed transformers were installed while he equally facilitated at least additional 800 poles solar panel street light spread across Lagos West Senatorial District.

On provision of educational infrastructure, the senator facilitated the supply of 750 prefabricated chairs and desks for 13 public nursery and primary schools spread across Lagos West at Ojo, Badagry, Oshodi-Isolo, Mushin and Alimosho. Furthermore, he facilitated the construction and installation of a multi-million-naira Information, Communication and Technology(ICT) centres in two public secondary schools in the district namely Ikotun Senior High School, Ikotun and Muslim College, Egbe. This brings the number of such centres that he facilitated to six as four of such were done by him in the 8th Senate. He also facilitated the construction of state of art Public Library at Adeniran Ogunsanya College of Education, Ijanikin, Lagos State.

Still on educational front, Senator Adeola facilitated the construction of 10 Block of Classroom spread across the three Educational Districts of Lagos West. He distributed educational materials in form of 15,000 textbooks in Mathematics and English Language for selected schools across the senatorial district for JSS1-JSS3 as well as exercise books, modern writing boards, school bags and other learning aids.

Again in 2021, in complementing the effort of State and Local Government authorities in the provision of health care for the citizens, he facilitated the supply of fully 10 Ambulances to be distributed to 10 General Hospitals as well as 10 Child Incubators. Furthermore, 17 Primary Healthcare Centres (PHCs) were renovated while three new ones were constructed across the senatorial district. All the PHCs and General Hospitals also received medical equipment and drugs worth over N20 million needed for effective operations over time.

To assist the state government in the provision of security, Senator Adeola facilitated the supply of 8 Hilux SUVs for the Nigeria Police Force with the donation of one each to the 7 Police Area Commands in Lagos West senatorial district and one to the State Police Headquarters.

As part of my alleviating suffering and inconveniences of constituents and others visiting or transiting through our district, the senator facilitated the construction and rehabilitation of 15 inner and rural roads, drainages and culverts with asphaltic finishing. Among them are: 1. Apata Street, Alfa Nla, 2. Ireakari/Fagbile Street, Off Kayode Street, Onipanu, Mushin LGA, 3. Alakija – Navy Town Road, Amuwo Odofin LGA, 4. Oritshe Street, Ikeja LGA, 5. Dotun Adewale Street, Off Dayo Olowo Alimosho LGA, 6. Oko Afa- Ilogbo Road, Olorunda, Badagry LGA, 7. Temidire Road, Mosalasi Bus Stop, Alagbado, Alimosho LGA, 8. Olowologbon Street, Akowonjo, Alimosho LGA, 9. Vespa Market Road, Ijanikin, Ojo 10. Ifelodun / Tanimola Street, Ilasamaja, Oshodi- Isolo LGA, 11. Muyibi Street Ajegunle, Ajeromi Ifelodun LGA, and, 12. Shodipo Street, Olusosun, Off Kudirat Abiola Road Behind Phillips, Ikeja among others.

To boost market infrastructure and commercial activities in the Badagary Division of the senatorial district, Senator Adeola facilitated the construction of 80 Lock up/open roof market stalls in Apa Town, in Badagary. This facility is already in use by constituents. The senator also facilitated employment in Federal Agencies to no less than 30 constituents, ensured that over 100 constituents benefitted from CBN loans to cushion effects of the impact of COVID-19 on businesses from sums ranging from N250,000 to N5million as well as ensured that thousands of constituents benefited from the Special Works Programme of the Ministry of Labour and Productivity with a special payment of N60,000 per participants late last year.

There is no doubt that Senator Adeola is at the forefront of highly performing senators of the 9th Senate. Indeed, he has been ranked among the top 10 in terms of bills sponsorship and passage. He fared relatively well in the projects he was able to deliver for his constituents in the largest senatorial district in terms of population in Nigeria and one is sure that if this area is ranked as was done for bills sponsorship, he will equally fall among the topmost senators in the 109-member Red Chamber. From the projects attracted and executed through him and through his facilitation, there is no doubt he squarely falls within the top 10 in this aspect also and indeed has something to showcase as a top-performing senator.

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.
