Solvothermal Liquefaction of Polyolefin Waste Plastics in Carboxylic Acid for Circular Plastic Recycling in Ghana, West Africa
Short Introductive summary
Plastic pollution poses a significant environmental and socio-economic threat across Africa, with Nigeria and Ghana generating about 3.5 million tonnes of plastic waste annually. Hydrothermal liquefaction (HTL) is a thermochemical conversion method that uses sub- or super-critical water to convert carbon-containing materials including biomass and plastics into liquid products. HTL is fast becoming a promising technology for recycling and/or energy production from various types biomass and plastic residues. This research focused on “Hydrothermal Liquefaction for Circular Plastic Waste Management in Africa: A Pathway for Climate Action” explores the feasibility of Hydrothermal Liquefaction (HTL) as a sustainable, circular alternative for converting mixed plastic/plastic-biomass waste into high-value oils to promote circular economy and climate action in Africa. This study integrates four key areas: experimental (co-liquefaction of biomass and plastics), environmental, economic, and policy perspectives. Hydrothermal Liquefaction (HTL) experiments will be conducted using mixed plastic feedstocks to optimize oil recovery and assess operational challenges.
