Due to the sharp rise in costs, Hakler, a well-known German toilet paper manufacturer, began to use coffee grounds as raw materials to produce to ease the difficult situation. Agence France Presse reported on the 18th, citing Karen Yunge, the company’s chief marketing officer, that the European food industry produces a large number of coffee grounds every year, and Hackleberry has found a papermaking method using coffee grounds as raw materials. Last week, the company used a new method to make the first batch of toilet paper. In the future, it aims to use coffee grounds as 20% to 25% of the papermaking materials.
