PROCESSING OF DIGESTATE AFTER THE DRY FERMENTER

TREATMENT OF SSO BEFOR THE WET FERMENTATION

The processing of biowaste, such as kitchen waste, produces:

• Liquid phase as biogas substrate for wet fermenters
• Solid phase for energy recovery


Digestate from the dry fermenter (fed with biowaste and green waste as substrate) can be processed into the following fractions:

• Solid phase for post-rotting and ultimately compost
• Liquid phase as agricultural fertilizer

Conversion of the organic matter present in the biomass into biogas and clean agricultural fertilizer

The ALLRECO screw press can be used both as a pre-treatment step for biowaste and food waste before the wet fermenter and as a post-treatment step for digestate after the dry fermenter. Equipped with the feed hopper, it can break down the feedstock and then separate it into a solid and a liquid fraction. The focus is not on recovering as much biogas potential as possible from the feedstock, but on providing a clean biogas substrate with a single machine, without pre-treatment, which subsequently requires no further post-treatment after the digester.
