If we can’t recycle or compost your waste, often we can use it to generate energy and heat, as well as to collect leftover materials for recycling. Every year, we divert 90,000 tonnes of non-recycled household waste from landfills to SITA’s energy-from-waste (EfW) process site in Teesside.
How your rubbish produces electricity
Recovering energy from household waste means we use less fossil fuels such as coal, gas and oil. This not only preserves these resources, it also means we produce fewer emissions of greenhouse gases.
The energy-from-waste (EfW) process allows waste to be diverted from landfills where decomposing here would have created methane – a greenhouse gas.
Emissions must continuously be monitored in order to comply with the demands of the European Waste Incineration Directive. Using the EfW process, the cleaning system filters out particles which will be disposed of at a licensed, special waste disposal facility.
The EfW process recovers energy in the form of electrical power and heat. Northumberland’s waste alone produces enough electricity to light and heat nearly 4,500 homes a year.
Through this process we are also able to recover valuable recyclable by-products, which might otherwise be landfilled e.g. metals are recovered and inert bottom ash is used in construction as a secondary aggregate.
