The guide is aimed at helping professions working in construction to achieve 'waste neutrality' by considering factors such as where the value of construction materials wasted is equal to the value of additional reused and recycled content used on a project, and allow the construction strategy to include a process to offset environmental impact.
'It presents a real opportunity to lead by example,' said WRAP's head of construction Mike Watson.
'The Net Waste Method will measure progress towards waste neutrality on a construction project by considering both the value of reused and recycled materials going into the works, and the value of waste materials coming out.
The focus on value helps contractors identify priorities for action and offers industry an opportunity to reduce costs and increase profits through waste reduction and improved site waste management.'
The Net Waste Method can be used as a transparent performance measurement tool to show corporate social responsibility and sustainability credentials and will fit into Site Waste Management Plans.
It also aims to encourage contractors to deliver real results in reducing waste and increasing the recycled material they use.
WRAP's Mike Watson continued: 'As a result of its appearance in public policy documents such as Defra's Waste Strategy, the goal of 'waste neutrality' is gaining increasing recognition in the construction industry.
This has generated a growing need for a clear definition and an industry standard. The Net Waste Method aims to provide this standard, and allow clients and contractors to demonstrate a committed approach to sustainability.'
Progress on projects will be measured by considering the value of reused and recycled materials going into the works and the value of waste materials coming out.
'We hope that construction clients look carefully at this real opportunity for improving profitability and reducing impact on the environment,' said Don Ward, WRAP's chief executive at constructing excellence.
