Waalwijk, Netherlands

Bright Biomethane has supplied the biogas upgrading system at a biogas plant in Waalwijk, the Netherlands, with the purpose of generating Renewable Natural Gas from various waste streams like roadside grass, vegetable waste, flotation sludge’s and depackaged supermarket waste. The RNG is injected into the national gas grid. The biogas upgrading has an innovative heat recovery system, so that no gas is needed for the heating of the digester.

The upgrading kit including compressor, membranes, control panel, heat recovery, odorisation and biogas analysis is placed in three containers. The three containers are located at an upgrading island besides the AD-plant.

Bright Biomethane also delivered the COliquefaction plant, to capture and liquefy CO2, with a capacity of 1322 lbs/hr and the CO2 liquefaction storage plant. This captured CO2 is used in the food and beverage industry.
