David Workman, director general of British Glass, will debate the issue of commingled waste on 10 June 2009 with Richard Skehens, MD of Grundon Waste Management & chair of ESA (Environmental Services Association). This is one of a series of lively head-to-head debates involving industry's most knowledgeable & passionate experts, which will take place at Futuresource 2009, the joint CIWM & ESA conference & exhibition at London ExCeL on 9-11 June 2009. Commingled waste is a contentious issue as more & more local authorities are relying heavily on commingled collections. This is where all recyclable materials (glass, paper, plastics, metals & textiles in some instances) are collected together & sent to a Material Recovery Facilities (MRF) for sorting in the erroneous belief that this is a cost effective "one-stop solution."
