Recent Study Reveals New Renewable FR Material Using Coffee Waste

Dr Henry Leung from the School of Chemical and Life Sciences and his team of three final-year students from the Diploma in Medicinal Chemistry found a way to lessen the environmental impact of coffee waste. They have turned used coffee grounds into a flame retardant that could potentially be used to improve fire safety in homes and offices.

Leveraging Slow-burning Properties of Coffee By treating coffee waste and mixing it with epoxy resin – a material commonly found in floorings and walls of homes – the team were able to leverage the slow-burning properties of coffee to create a material that could withstand a fire by as much as two times that of regular epoxy resin. This new material has also attained an “HB” grading, which indicates slow burning on a horizontal specimen, based on initial findings by a third-party testing laboratory. Apart from its fire-resistant qualities, the coffee-epoxy resin has the potential to become a total solution for reducing coffee waste as grounding coffee waste into compost requires large storage space. The incineration of compost is also a space- and energy-consuming process. Source: NYP
