BIOPLASTICS | FORMULATION AND COMPOUNDING
Right: Spent coffee grounds could find their way into new bioplastic
compounds as a renewable filler
Coffee concepts A UK-based recycler of coffee grounds is looking at how they might be used as a filler in bioplastics compounds. Bio-bean, which was founded in 2013, originally used coffee grounds collected from various industrial and retail sources to make Coffee Logs for burning on wood stoves. Two years ago, it launched its first natural flavour ingredient into the food and beverage industry and it contin- ues to look for new outlets for the grounds. The company says an estimated half a million tonnes of waste coffee grounds are produced annually in the UK alone. Typically, they are sent to landfill or anaerobic digestion. “Spent coffee grounds, renewed and upcycled for reuse, are a sustainable, bulk raw material with versatility across a wide variety of industries,” according to the company. “From plastics to automotive friction, and from cosmetics to textiles and more, spent coffee grounds offer a sustainable alternative to virgin or synthetic materials whilst also reducing waste.” Collected grounds are put through a proprietary decontamination process at Bio-bean’s facility at Huntingdon before being dried. One of the most recent resulting products is Inficaf, which is consist-
ent in particle size, moisture content and bulk density. The company says this makes it a versatile raw material for potential opportunities ranging from automotive parts to 3D to bioplastics. “Inficaf is a valuable, sustainable filler for plant-based polymers, replacing traditional mineral fillers. It can also be used as a filler for traditional plastics and composites, displacing the use of virgin petrochemicals,” the company claims. Bio-bean says it has several live projects currently
