Aberystwyth University Graduate Student Converts Diapers into Biofuel

Every year, the UK produces 1 million tonnes of Absorbent Hygiene Product (AHP) waste with the majority going to landfill sites and contributing to the build-up of greenhouse gas emissions.

Joe Freemantle, a biology graduate of Aberystwyth University, could provide a solution. He has developed a process that turns disposable nappies, incontinence pads and sanitary products into valuable products, including pure cellulose fiber and biofuel.

Joe's intention was to intercept AHPs and allow the recycling of valuable components, reducing the amount that end up in landfills/incinerators. In Joe's method, the AHPs are processed, separating the fibers from the plastic components, and the sanitary waste are made non-toxic, before fermentation to liquid transport fuel. The process also allows the regeneration of pure and valuable cellulose.

Joe's concept was based on converting used cigarette butts into biofuel, an idea he and friends developed. This led to establishing start-up company Green Phoenix and the project to convert used nappies and sanitary waste.
