Script for video: Food waste - how it is recycled
Waste food has a big impact on climate change as most of it ends up in landfill sites where it rots and releases methane into the environment.
The best thing we can do with our food is enjoy it but some waste like egg shells, banana skins and tea bags is inevitable.
Many Councils now collect food waste which can be recycled in one of two ways; The first, In-vessel composting, involves mixing food waste with garden waste - shredding it and then composting it in a tunnel for around 2-4 weeks (temperatures of up to 70°C speed up the process and kill of any harmful microbes) - which is then left for a further one to three months with regular turning and checks to ensure quality before going to be used as soil conditioner.
The second method, Anaerobic Digestion, uses microorganisms called methanogens to break down food waste, animal manure and energy crops in the absence of oxygen inside an enclosed tank. As it breaks down it gives off Biogas which is collected and used to generate electricity, heat or transport fuels. It also creates bio fertiliser that can be used in farming and land regeneration.
Ask your council if they recycle food waste and which foods you can include. Visit recyclenow.com for tips on recycling more of your waste.
