Abstract
The present invention relates to a process for the treatment of waste in a reactor (3) comprising the steps of combining the waste to be processed and an aqueous, alkaline solution to form a reaction mixture, heating the reaction mixture to a temperature range between 140° C. to 250° C. and a pressure between 3 bar and 12 bar to produce at least one aqueous, organic phase, a gas phase and optionally a solid phase, removing the gas phase from the reactor (3), separating the organic and aqueous components of the gas phase, in particular by means of a rectification column and feeding the aqueous components of the gas phase back into the reactor.

A process for the treatment of waste in a reactor (3) comprising the following steps:
- Combining the waste to be treated and an aqueous, alkaline solution to form a reaction mixture;
- Heating the reaction mixture to a temperature range between 140° C. to 250° C. and a pressure between 3 bar and 12 bar to produce at least one aqueous, organic phase, a gas phase and optionally a solid phase;
- Removal of the gas phase from the reactor (3);
- Separation of the organic and aqueous components of the gas phase, in particular by a rectification column (4);
- feeding the aqueous components of the gas phase back into the reactor (3).
