As the world's largest coffee chain, Starbucks consumes about 4 billion disposable cups worldwide each year. If consumers want to reduce this waste, they can certainly bring their reusable cups to the coffee shop.

However, Huskee, an Australian start-up, has a better idea, recycling coffee bean shells (parchment) that are often discarded to make reusable coffee cups-- HuskeeCup.

The coffee bean is the seed of the coffee fruit, and the coffee bean shell is the parchment around the seed.

According to the company, the world produces more than 1.48 million tons of coffee bean shell waste every year. Although these shells can be used as fertilizer, most of them will be dumped.

Coffee bean shells have always been used as fertilizer or even fuel, and there is no other economically viable and sustainable treatment.

Coffee farms in Yunnan, where the shells of HuskeeCup are produced.

Huskee is currently buying coffee bean shells from coffee plantations in Yunnan, China, and converting them into a ceramic resin. The resin is used to make coffee cups and HuskeeCup is reported to be crack resistant, stackable and recyclable through microwave oven / dishwasher safety tests.

The HuskeeCup comes in 6-ounce, 8-ounce and 12-ounce cup sizes to match the accompanying plate.

Other features of the HuskeeCup coffee cup include a design to reduce the surface area on both sides to avoid scalding customers' fingers. In addition, it is said that the thermal insulation effect of this resin is better than that of conventional ceramics.

Huskee has launched crowdfunding for the coffee cup on Kickstarter, and the company has designed three different models of cups and accompanying plates. The price of four 6-ounce (180 ml) cups is 45 Australian dollars (234 yuan).
