Compostable materials are the only ones that guarantee the closing of the cycle with zero waste, by placing the materials in an appropriate compost/digester, where they are fully degraded for up to 12 weeks so that they can be reintegrated into the soil as fertiliser, providing bionutrients and contributing to the maintenance of green spaces. They also have the additional benefit of improving the soil structure, as well as being sourced from renewable sources generating lower CO2 emissions.
