Food residue and kitchen waste as input material for biogas systems

Degreasing and Processing of Food Residue

Food Residue Processing and Recycling in Biogas Systems

About a third of the food produced in the world ends up as food residue and biowaste. Ever-growing amounts of food residue are collecting, especially in production, in restaurants, cafeterias, and supermarkets.

Aside from feeding these residues to animals, now largely prohibited, food residue can also be used as a raw material for energy production in biogas systems. 

Food Residue Degreasing Using Centrifuges

Both decanter centrifuges and the Tricanter® are used by disposal companies for the recycling of food residue and kitchen waste.

Flottweg decanter centrifuges separate the oil from the raw materials.

This separated oil has a purity of over 98% and is recycled as grease. The yield is optimum: the oil portion in the centrifuge discharge is less than 1%.

The residue, consisting of water and solids, can be used as an energy source for biogas systems or further dewatered.

Decanter centrifuges extract the valuable oil for use as biodiesel material

The Flottweg Tricanter® separates food residue into three phases in just a single step. In addition to the oil, the machine also extracts the solids from the water.

The robust construction of the centrifuge allow quantities and solids particles of different sizes to be separated without problems. It is used as an input material for biogas systems.

The separated wastewater can then be further processed in community sewage treatment plants.

Just one step to oil, water, and solids, with the Tricanter® for food residue processing
