B4 Energy April 2025

Demand for renewable energy is growing, while traditional energy sources are becoming increasingly scarce. Among others, agricultural and food sector companies produce many organic residual streams, which are often not optimally utilised. While these can be a valuable source of renewable energy. B4Energy converts these residual streams into green gas, thus contributing to a more sustainable energy supply and less dependence on fossil fuels.

This is how B4Energy works

B4Energy, an initiative of lettuce and celery specialist B-Four Agro, built an innovative biodigestion plant and gas reprocessing unit in Warmenhuizen. Here, biomass consisting of vegetable residues is converted into green gas. This green gas is fed into the natural gas grid and provides both households and B-Four Agro's cultivation systems with sustainable energy.

The impact

By producing green gas from local waste streams, B4Energy contributes to:
● Reduction of fossil fuels
● More optimal use of agricultural residues
● A more sustainable energy supply in North Holland

Collaboration and support

The bio-digester and gas reprocessing plant were completed in mid-2016 in cooperation with local contractors and with financial support from the Participatiefonds Duurzame Economie Noord-Holland (PDENH). This made the project not only an energy source, but also a boost for the regional economy.
