Circular Business Models in Textile Waste Management

Onwunmelu Wisdom Nnadozie

MSc. Student (Environmental Systems and Climate Change), World Bank Centre of Excellence in Agricultural Development and Sustainable Environment (CEADESE), Federal University of Agriculture, Abeokuta, Ogun State.

Onwunmelu, Wisdom Nnadozie is a sustainability and environmental researcher. He holds a Bachelor’s degree in Soil Science and is currently pursuing a Master’s degree in Environmental Systems and Climate Change at the World Bank Centre of Excellence in Agricultural Development and Sustainable Environment (CEADESE), Federal University of Agriculture, Abeokuta, Ogun State, Nigeria. His current research focuses on the comparative assessment of thermally pre-treated and untreated rice husk for biogas production when co-digested with cattle dung. The research’s goal is to improve understanding of how agricultural waste such as rice husk can be effectively managed and efficiently converted into renewable energy thereby promoting the circular economy practice in Nigeria. Wisdom has led and volunteered in several climate change and environmental sustainability initiatives. Notably, he participated in the Tide Turners Challenge organized by Junior Achievement Africa in partnership with the United Nations Environment Programme (UNEP), where he emerged as one of the African champions. He has co-authored one academic publication and three non-academic publications, all aligned with his interests in environmental protection, waste management, and climate action.

Wisdom is passionate about impactful, applied research and is skilled in environmental impact assessment and sustainability reporting. His long-term goal is to contribute to the design of scalable climate and circular economy solutions that support sustainable development in Nigeria and other developing countries.

Mayowa Oke

Civil Servant

Mayowa Bernice Oke is a doctoral researcher in environmental sustainability with an interdisciplinary academic background in microbiology and sustainability studies. She holds a Bachelor of Science in Microbiology and a Master of Science in Sustainability Studies with specialization in Environmental Sustainability. This academic foundation informs her systems-based and evidence-driven approach to addressing complex environmental challenges, particularly in the areas of waste governance and pollution management.

Professionally, she has gained practical experience with the Abuja Environmental Protection Board (AEPB), where she engaged with urban waste management operations and regulatory processes. This exposure has strengthened the applied dimension of her research and deepened her understanding of the institutional and policy dynamics shaping environmental outcomes in Nigeria. Currently at an advanced stage of her PhD programme, Mayowa’s research critically examines the effectiveness of plastic waste management techniques and their implications for environmental sustainability in Nigeria, with comparative analysis of the Federal Capital Territory and Lagos State. Her work integrates empirical data, policy evaluation frameworks, and sustainability assessment tools to interrogate the relationship between policy design, implementation, and environmental performance. Beyond her academic pursuits, she is committed to sustainability advocacy and knowledge dissemination, with plans to develop a digital platform dedicated to waste management awareness to enhance public engagement and policy literacy. In her leisure time, she practices photography, which serves as a complementary medium for visual documentation and environmental storytelling.
