Our team solution combine two opportunities for following issues: lack of possibilities of beer spent grain waste and waste generated by ordinary single use cups. By combining these two ideas we propose a cup made from grain waste.
Why it will work.
Waste like chaffs can be gathered from breweries and reused not only by animal feed market but by food consumables manufacturers as well. Cleaned spent grain wastes can be mixed with structural element like soybean flours which has semi-water proof abilities. It is worth to mention, that chaff has natural waterproof layer which we can use for our already mention intensions. The materials composition let us to have stable waterproof surface.
How we will make it?
Mass of beer grain wastes and structural element (polymer) mixture can be baked in cup form modules, for this reason this process easily adapt to mass production. To increase waterproof ability the cup from outside will be covered by natural food related wax (like fruit wax).
What is the value?
1. It can decrease brewing process related wastes,
2. Generate additional value for beer wastes (revenue),
3. To decrease plastic waste in the world,
4. Can be used as an animal feed after use again,
5. Easy to decompose
