Abstract:
A process for the separation of a mixture of waste into a combustible fraction and a non-combustible fraction, comprising the steps of:breaking up and homogenizing the mixture;composting and stabilizing the mixture in a closed container under forced ventilation for 5 to 10 days to create an intensive rot;terminating the intensive rot by drying the mixture to below 15% residual humidity;subsequently separating the mixture into a combustible fraction and a noncombustible fraction by screening, and pneumatic separation following the screening;wherein the resulting combustible fraction contains less than 10% by weight of non-combustible substances, andwherein the resulting non-combustible fraction contains less than 5% organic substances.
