The use of plastic and other forms of waste to generate fuel, though recent, promises to be a reliable option for effective waste management.
The method, however, is expensive and time-consuming as it involves sorting in various material base before processing.
A group of students of the Kwame Nkrumah University of Science and Technology is exploring ways of generating fuel without separating waste.
“People have started building technologies that can convert only biomass into fuel and only plastic into fuel, but our idea is to convert both plastic and biomass into fuel,” says team leader, Jonas Yeboah.
The process known as pyrolysis involves burning plastic and plant or animal parts in a temperature range of 200-760°C.
The process produces gas and sometimes liquid products leaving solid residue.
