From that waste we recover in Alphen aan den Rijn three high-quality raw materials with which we are closing another materials loop:

• Compost: a natural soil improver that replaces fertilizer and fossil peat.
• Green gas: wet organic VGF waste is digested into biogas. We upgrade that to green gas of a very high quality, which replaces fossil natural gas.
• Liquid CO₂: CO₂ is released when biogas is refined into green gas. Bio Power Alphen compresses this into liquid CO₂. This has various applications, including in horticulture for stimulating plant growth
