An Australian startup, Huskee, has developed reusable cups which are made from unwanted coffee bean husks.
According to Starbucks, over 1.35 million tonnes of coffee bean husk waste is generated globally every year. A small proportion is used as fertilizer but most goes to landfill.
Huskee converts the coffee bean husks into a ceramic resin that they use to make the coffee cups. The company says that their cups are chip and crack resistant, microwave and dishwasher-safe, stackable, recyclable – and tasteless.
The cups are currently the subject of a Kickstarter campaign, and are initially being offered in three sizes with accompanying saucers.
