A prototype for a reusable cup made from 72% used coffee grounds, 18% bioresin, a non-toxic glue made from a by-product of the widget industry, 9% ground rice husks, a waste product of the rice growing/processing industry, and 1% vegetable dye. Advertised as Carbon negative due to the high percentage of reclaimed material used in its manufacture. This sample cup was created by Cambond Ltd to demonstrate how technology can combine plastics with plant mass to form polymer composites, to explore the mechanical properties of coffee/polymer composites and to verify manufacturing technologies. The glue was developed by Cambond as a plant-based alternative to existing toxic options. At the same time as the company were developing their glue they were reading about the amount of coffee cups ending up in landfill. Cambond benefited from a the Design Council's Spark programme which was launched in 2014 and was a support and funding scheme created to help inventors and entrepreneurs turn ideas into commercially viable products. The deep ridges around the cup help to keep the hand away from the hot surface and therefore comfortable to hold. The cup was an entry for the Horners Award for Plastics Innovation & Design 2017.
