Reusable cup
Whether in muesli, as a crunchy salad topping, or to refine baked goods – sunflower seeds are incredibly versatile and packed with nutrients. They provide magnesium, folic acid, vitamin E, fiber, and high-quality plant-based protein.

It’s not just the seed itself that holds potential – the shell does too. While sunflower seed shells are technically edible, they’re considered difficult to digest. For this reason, sunflower seeds are usually processed after being shelled. Since the shell accounts for around 15 to 20 percent of the seed, large quantities of shells accumulate as a by-product during the production of both sunflower seeds and sunflower oil.
A company from Lower Saxony is using this residual material to create innovative and biodegradable products – for example, a reusable cup.
Durable thanks to two components
The cup is made from two sustainable components: a stable core material derived from sunflower seed shells and a protective outer layer made of bio-PBS, a biodegradable plastic based on corn starch. This combination makes the cup particularly robust and durable – it can even withstand many dishwasher cycles.
At the end of its life cycle, the cup can either be ground back into granules and turned into a new product or disposed of in compost, where it decomposes over the years into biomass, carbon, and water.
