Dr Taiwo Babatunde Hammed holds bachelor degree in Environmental Management and Toxicology from Federal University Agriculture, Abeokuta, Ogun state (1999) and both masters (2009) and PhD degrees (2015) in Public Health (Environmental Health) from the University of Ibadan, Nigeria. He attended UNESCO-IHE’s Netherlands Fellowships Programmes (NFP) on Solid Waste and Engineering (2008). In 2017, Dr Hammed enjoyed Post-Doctoral Fellowship under Climate Impacts Research Capacity Leadership Enhancement (CIRCLE) programme at Institute for Climate Change and Adaptation, University of Nairobi, Kenya jointly organized by African Academy of Sciences, The Association of Commonwealth Universities and UKAid. He was also a Fellow of Blue Charter Programme on marine plastic waste pollution at the University of Plymouth, UK (2019). In recognition of his contributions to the field of Solid Waste Technology and Management, he received Roy F. Weston Award at Widener University, Phildelphia, Pa, USA in 2016.

Following his various action-oriented and community outreach programmes, Dr Hammed has developed many innovative technologies that have earned him ten patents, approved by Nigerian Government. These technologies have already been linked with and tested in some needy communities in Nigeria for acceptability and sustainability.  Further, he has worked in various consultancy services for national and international organisations. Among these are: UNEP global marine plastics stocktake (African Lead), UNICEF’s Sanitation Hygiene and Water (SHAWN) Project in Benue, Bauchi, Jigawa, Katsina, Kaduna and Zamfara States, Nigeria (Co-Researcher) and MTN Nigeria Foundation Environmental Health Project at Alesinloye market Ibadan (Project Manager). Dr Hammed is currently the Technical Director of TETFund-sponsored Renewable Resources Centre, University of Ibadan, Senior Key Waste Management for EU-funded Nigerian Climate Change Response Programme (NCCRP) and one of the Nigerian scientists in the UNFCCC roaster of Experts. His research interests span areas such as: solid waste recycling (composting for food production, biogas, biodiesel, refuse derived fuel from plastics and other energy recovery from natural material and waste), and climate change impact from wastes. Many of his translational researches have been published in both local and international peer review journals.

Title: Waste Buy-back Activities at Kube-Atenda, Communities Ibadan
Funder: The Association of Commonwealth Universities and UKAid
Brief Summary: As climate change has become a great public health concern with poor solid waste (litter) management being a significant contributor to this problem. This is a Climate Impacts Research Capacity Leadership Enhancement (CIRCLE) research uptake activity for scaling up a waste buy-back centre at Kube-Atenda, Ibadan, Nigeria. There was promotion of solid waste buy-back centre for plastics, paper, metal etc at Kube-Atenda in Ibadan North Local Government Area. It aims at preventing waste related diseases and climate change effect. At the end of the project, the knowledge and practices of mitigating greenhouse gas emission through waste recycling in the community was improved.
Role: Researcher
Collaborators: Sridhar M.K.C (University of Ibadan), Prof (Shem O. Wandiga (University of Nairobi, Kenya), Yacob Mulugetta (University College London, United Kingdom), DFID (UK) and African Academy of Sciences (AAS).

Title: Waste to Electricity in at Kube-Atenda community in Ibadan
Funder: The Association of Commonwealth Universities
Brief Summary: This a second round of the Climate Impact Research Capacity and Leadership Enhancement programme (CIRCLE) Research Uptake Fund. The current uptake focused on a new innovation that used smokeless pyrolytic chamber to convert various solid wastes to renewable energy and useful by-products to address the challenges being faced in a community in Ibadan. The project centre has become a study area for researchers and postgraduate students in the University of Ibadan and other universities in Nigeria. The research uptake was expected to meet the community people needs in the area of community development, clean environment, people’s capacity building in waste to wealth concept for wealth creation and poverty reduction, improved health and improved self-esteem. In addition, the uptake activities will facilitate and contribute to the use of research evidence by policy makers, practitioners and other development actors in the state in general. Lastly, the transformation in the community would surely arouse the interest of policy makers to turn evidence into policy action.

Title: Plastic Waste Disposal into Water Bodies and Mitigation Measure through Community Level Interventions along Nigerian Coastal Corridor
Funder: Waitrose & Partners; Association of Commonwealth Universities (ACU)
Brief Summary: As part of the Commonwealth Marine Plastics Research & Innovation Framework (MPRIF), the project includes tackling marine pollution – specifically the issue of marine plastics, which were drastically affecting the health of our oceans, marine life, and the Blue Economy. This collaborative research focuses on community-led waste plastic management in an organized manner at various communities along coastline where various activities may be contributing to marine plastic pollution. It has to do with the all aspects of sustainable plastic waste management including: identifying hot spots of plastic pollution along coastline in Lagos, quantifying the quantity of plastic waste that enters ocean through the lagoon, rivers and open drains, identifying the common types of plastics in the ocean, documentation of factors that contribute to plastics disposal into water bodies and sensitization of community people on alternative management of plastic waste through concept-reduce, reuse, recycle (4Rs) concept. The research was carried out the under Blue Charter Fellowship Knowledge Exchange Grant Scheme
Role: Researcher
Collaborators: Prof Sabine Pahl (University of Plymouth, UK) and Prof Paromita Chakraborty (SRM Institute of Science and Technology, India)

Title: Global Marine Plastics Stocktake
Funder: United Nations Environment Programme (UNEP)
Brief Summary: This is line with data collection on the quantity of plastics and practices Reducing marine litter and microplastic discharge to the ocean across the continents in the world. Checking and validating existing data via a range of methods such as internet searches and following up a sample of submissions via phone calls or e-mails. The overall number of submissions was split between four academic partners, with each partner mainly focusing on their geographical region (e.g., Latin America and Caribbean, Africa, Asia-Pacific, Eastern European, Western European and others).
