Turning waste into biogas

When biomass decomposes, it releases carbon dioxide into the atmosphere and accelerates thus climate change. Watrec designs, supplies and operates biogas reactors where tiny organisms break down biomass so that it can be used as fuel for cars or as sources of energy. The biogas reactor also collects precious nutrients that can replenish the natural cycle.



A lot of biomass is left unused even though it could potentially be used for energy production. For example, biodegradable waste, industrial slurry and agricultural biomass could be used even more than they are now. The biomass combustion process alone wastes a great deal of nutrients and humus even though global phosphorous stores and the soil are being depleted at an alarming rate. Because of the effects of climate change, people must stop using fossil fuels as soon as possible and prioritise local and renewable clean energy production.

Solution: biomass-based energy and nutrients

Watrec designs and constructs industrial plants that refine organic matter into renewable energy (biogas) as well as soil improvement and fertiliser products. The processes of these industrial plants combine the company’s technological solutions as well as pre-existing technologies. One regular biogas plant can be used to reduce around 9,000 equivalent tons of carbon dioxide per year.

Revenue logic and benefits for Watrec

Watrec generates revenue by sharing its expertise, designing solutions and selling its technologies and plants on a turnkey basis. The company has also signed operating agreements with biogas and waste-water treatment plants on a case-by-case basis.
