Materials and Waste: Week 5

Technology for mushroom cultivation General information on conditions for growing mushrooms on spent coffee grounds In order to grow mushrooms on coffee waste you need certain circumstances. In traditional cultivation methods you need bacterial control at high costs, but since the coffee ground is exposed to hot water, bacteria are already reduced to a minimum. Farming mushrooms on coffee spent…

Technology for mushroom cultivation There is no worm farming facility on Texel available yet. Technology to create a worm farm already exists by using worm composting containers and could therefore already be implemented in 2020. Worm farming requires knowledge about nutrients for worms. Fruits and vegetable scraps, egg shells, shredded paper products, fallen leaves, tea bags, coffee ground, lawn…

Technology for aquaculture Research for creating optimal conditions for aquaponics is still on-ongoing. This also makes it hard to estimate how much fish and nutrition is needed to keep the eco-system in balance. It also depends on the types of fish and types of plants. Therefore it is hard to make a technology roadmap from 2020 to 2065. Texel is known for its research on marine life. This…

Technology for the new transport system To become a sustainable island, Texel needs to change its current sub-system of Materials and waste. In the proposed design there will be the need of moving waste streams within its new neurons-like network. Waste will not be considered anymore as waste, but as food, to be fed into another part of this sustainable chain. One of the new technologies to be…

To implement a successful biodigester on Texel, first has to be analysed which actors have to be involved and what their needs are. Before going into detail on Texel, first general information about biodigesters is given in the subchapter ‘technology’. Technology: The technology of biodigesters Anaerobic digestion in a biodigester is a process by which microorganisms break down biodegradable…
