Restaurant & Catering

This is how you immediately build a green business operation...
Achieving a significant CO₂ reduction and at the same time saving on your energy costs, is possible with Circ

Food scraps

Plates with leftovers, cutting waste from the kitchen, coffee grounds, etc. A restaurant produces many kilos of food waste every day. The Circ BioTransformer converts these organic residual flows into BioGas and BioWater. This way you immediately save energy costs, reduce your transportation costs and help to create a better world.

Energy costs

The Circ BioTransformer improves your processes in the kitchen. You will gain extra insight into your purchasing costs and it improves your CO2 footprint.

An ideal solution.

The Circ BioTransformer is a unique compact biodigester that converts food waste into sustainable BioGas and BioWater. You get about 0.4 m3 of BioGas from 1 kilo of GFE, depending on the type of input. And that's a lot! Biogas, the green variant of natural gas, can be used directly for central heating, hot water, and cooking installations.

The biogas can also be converted into electricity or used as a hybrid solution to use energy as efficiently as possible. The BioTransformer can therefore also be used in gasless environments.

Get that last bit of energy from your vegetable, fruit, and food leftovers and reduce your CO₂ emissions.
