We developed Britain’s first national model of solid waste arising, collection, treatment and disposal. The model uses our simulations of population, and combines these with alternative scenarios for waste arising from municipal solid waste (MSW), commercial and industrial (C&I), construction and demolition (C&D) at a regional scale.
The demand for solid waste infrastructure could vary enormously, depending on population/economic scenario and the waste reduction approach. In our most ambitious demand reduction strategy, investment would only be needed to replace ageing plant, with a net reduction in the required capacity.
Governments and local authorities are responsible for recycling the abundant amount of plastic waste we generate – a new model from the University of Southampton could help planners to decide on the best plastic recovery strategies.
