Wellness & Sauna's

Using your food leftovers as an energy source to heat your sauna's

Green Energy

Plates with leftovers from your guests, cutting waste from the kitchen, coffee grounds, etc. A restaurant in a wellness center produces many kilos of vegetables, fruit, and food leftovers every day. The Circ BioTransformer converts these organic residual flows into biogas that you can convert directly into sustainable energy. This way you save directly on your energy costs, reduce the disposal costs of bio-raw materials, and make the world a greener place.


Entrepreneurs are increasingly aware of sustainability. Companies that are known for using a lot of energy are also starting to work more sustainably. The energy consumption in wellness centers and saunas is relativity high.

Several locations are moving towards environmentally more friendly ways of energy consumption. By using a Circ BioTransformer, they can for example generate green energy locally and reduce food waste at the same time.

An ideal solution

The Circ BioTransformer is a unique compact digester that converts vegetables, fruit, and food leftovers into sustainable BioGas and BioWater. You get about 0.4 m3 of biogas from 1 kilo of food leftover, 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.
