Sustainable Management Fund Project
On Farm Plastic Waste (2005-2008) which became Agrecovery of which I was a board member (2009-2010)
"3R Group and the Agrecovery rural recycling programme in particular have had a long history of association with Darren and have always found him to work extremely professionally with a high degree of integrity. His understanding of central and local governement systems and politics and overall support was invaluable during the formative years of the Agrecovery programme. He clearly understood the need for a nationwide stewardship programme to address persistent on farm waste issues and was one of the key drivers to ensure it moved from SMF funded project to a reality. He is an expert in his field."
