Bio Plast Pom, based in Poland, says NOPLA is not a synthetic material. It is reportedly free of both artificial ingredients and plastics and is not thought to leave behind microplastics when it decomposes.
Apparently, the patent-protected material is biodegradable and compostable in a household composter, salt water, freshwater, and soil. It is designed to comply with the EN 13432 composting standards and claims to degrade in 3 to 6 months under household composting conditions.
