Bio-waste is defined as biodegradable garden and park waste, food and kitchen waste from households, restaurants, caterers and retail premises, and comparable waste from food processing plants. It does not include forestry or agricultural residues, manure, sewage sludge, or other biodegradable waste such as natural textiles, paper or processed wood. It also excludes those by-products of food production that never become waste.What do we do with bio waste?
Solutions for recovering bio waste exist. Mechanical biological treatment (MBT), which is a machine-assisted process, isolates the fermentable portion of waste from the rest of household rubbish. The resulting material is then recovered by composting or methanisation. Composting transforms organic waste into humus, a fertilising material for soil and gardens. Waste gradually decomposes under the combined action of water, microorganisms (fungi, bacteria, etc.) and oxygen. Methanisation, on the other hand, refers to a natural fermentation process in a closed environment designed to produce biogas. Bio waste recovery has undeniable advantages. By reincorporating them into their natural cycle, these elements can be used to enrich soil, or produce electricity and heat. Use of bio waste also reduces the need for chemical fertilisers.
