Kraft paper is made by boiling wood chips in sodium sulfide and sodium hydroxide to chemically convert them into wood pulp. Once the pulp is formed, it is screened to remove larger pieces, before being washed to remove any residual fluids. The resulting pulp can then be made into compostable coffee pouches of various shapes and sizes that are both strong and flexible. Under the right conditions and when left untreated, kraft paper can take as little as two to six weeks to decompose.

PLA is a bioplastic made by fermenting carbohydrates sourced renewably from crops like maize, cornstarch, and sugarcane. The fermentation process produces resin filaments that can be shaped, molded, and colored to suit a range of needs. In an industrial composting facility, PLA-based products can take as little as 90 days to decompose, in contrast to 1,000 years for conventional plastics.
