WRATE – The New LCA Tool for Waste ManagementTessa Bowering

Environment Officer (Waste)

What is WRATE? Waste and Resources Assessment Tool for the

Environment LCA software tool for comparing different systems for

managing and processing Municipal Solid Waste Allows you to assess/consider the environmental impact

of all stages involved in managing and processing waste from collection through to disposal

Allows you to compare the environmental impact of the different options available at each stage of managing and processing waste to help make decisions when choosing waste management options

Life Cycle Assessment for Waste

RawMaterial

Production / Manufacturing Use End of Life

Raw material and energy

Emissions to air, water and soil

Why WRATE? Environmental impacts of waste operations are

balanced against benefit of materials/energy replaced Whole life cycle accounted for – capital, maintenance,

operation, recycled materials etc. Takes into account emissions to the environment

from the whole system and any resources used EA role to provide sound, objective and impartial

advice to LAs on how much waste there is, where it comes from and what are the environmental impacts of managing it in different ways

Software not designed to rank waste management options

Why WRATE? (2) Waste strategy 2007: WRATE

recommended life cycle tool for informing decisions on waste

infrastructure options and; estimating global warming
