Why choose BIOPBS PAPER CUP?
The paperboard we use for our Paper Cups is manufactured from 100% virgin fibre. The wood used to make the board is from well-managed plantation forests purpose-grown for manufacturing into wood and paper products. Paper is a renewable resource, a key point of difference between Paper Cups and alternatives made from non-renewable materials.
- BIOPBS – A friendly catalyst to help you become an environmentally friendly brand
- RENEWABLE RESOURCE – By using bio-based material, we are not emiting more CO2 into the atmosphere
- BIODEGRADABILITY – BioPBS degrades at room temperature. There is no need for special composting facilities
We care about the environment, as evidenced by our compostable cups made of organic PBS coated paper. According to DIN EN 14995, our organic PBS cups are 100% recyclable and compostable. The plastic is made from sugar cane residues left over from sugar production. This does not result in a scarcity of food.
Our organic PBS cups are identical to our standard PLA cups. In terms of processing and handling, organic PBS coated paper is very similar to our traditional cups.
