Mass balance

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
