WRAP guidance on calculating recycled content

A new guide to help manufacturers of building products make credible declarations on the recycled content in products has been published by the Waste and Resources Action Programme (WRAP). As well as outlining how to calculate recycled content, it defines what can and cannot be considered as "recycled."

Developers in the public and private sector are including recycled content specifications in tenders (ENDS Report 391, p 23 ). WRAP recommends that all construction projects use at least 10% by value of reused and recycled content.

While manufacturers have previously been reluctant to promote the use of recycled materials in products, this is changing according to product suppliers such as Jewson and others in the industry.

Steve Hunt, project manager at the British Board of Agrément (BBA) - the approval body for construction products and installers - said it was aware of "increasing drive" for manufacturers to identify and promote recycled content with BBA certificates. He added that the guide would provide "the beginnings of a framework for us to validate the content".

According to the guidance, recycled content can refer to any material that is listed in the European Waste Catalogue, classified or intended to be classified as waste within ISO14021, offcuts or scrap that need processing before use or defined as by-products in the European Commission’s by-product guidance.
