People and nature not only consume organic matter, they produce it as well as food left-overs, fruit peel, rubbish from private and public gardens etc. At Texel, organic waste from households and restaurants is collected bi-weekly. As much as 35% (2013) of the organic waste is left with the general (mainly inorganic) waste. Garden and forest waste is mainly transported, as is manure from stockbreeding. At the same time, fertilizers are transported to the island. Shortly, to become 100% self-sufficient the system needs to change. How can organic matter in the future be recycled and/or upgraded on the island to maintain quality?
