The Center for Sustainable Development is excited to welcome 53 new students for the Island School spring 2017 semester program and is even more excited to welcome a group of these students to the CSD Repurposing Waste research team. This semester, we will be working on repurposing waste plastic into synthetic diesel fuel via a process called “pyrolysis.” Pyrolysis is thermal decomposition in a high-temperature and low-oxygen environment. Plastic is made from fossil fuels, so pyrolysis can be used to break down or “crack” plastic into its original petroleum constituents. Last semester, our research group worked to design, build and run tests on a lab scale model of a pyrolysis machine that was constructed out of all repurposed materials. Our efforts were successful in pyrolyzing a variety of different plastic types into oil which then was proven to be a usable diesel fuel alternative when it successfully started a concrete mixer!
This semester, we are continuing our pyrolysis research by designing and beginning construction on a second pyrolysis machine. This next iteration will be bigger, allowing us to pyrolyze larger batches of waste plastic at once, ultimately beginning to make a dent in the massive amount of waste plastic on our campus. It will also be a more sophisticated model allowing us to control multiple variables, such as the temperature, to collect more accurate data and run more efficient experiments. This semester’s Island School Repurposing Waste Pyrolysis Research Team will help to construct, run experiments and analyze economic and environmental data about the system.
We recently heard from one of our partners who has played an influential role in our pyrolysis research. Robert Clyne from Clean Sea Fuels has spent a number of years working to solve the problem of plastic and oil waste. He has specifically been focusing his efforts on developing countries where there is very limited access to recycling and safe waste disposal methods. Of late, Robert has been working on efforts to turn toxic waste oil into a diesel fuel substitute that he calls ReUse fuel. His organization’s first facility in Ghana has seen much success, and plans are underway to start a second facility in Burkina Faso. This facility will not only give people access to eco-friendly, locally-produced and low cost fuel that cleans up the environment, but also provides the benefit of making jobs for oil collectors, fuel makers and mechanics or fuel resellers.
Roberts’ current work is the first phase of a long-term goal to bring low-cost, eco-friendly sustainable recycling and mass production technology to grassroots entrepreneurs in developing nations. His system only requires a 12 volt pump, a solar deep discharge battery and a filtration system, making it completely mobile!
