Roger Wright, BIffa: My name's Roger Wright. I work for Biffa Waste Management, the largest waste management business in the UK. We cover about 95% of all postcodes, collecting both business and household waste. The business waste sector is the biggest part of our operation, but we also have several other interesting divisions—mechanical recycling of rigid plastics to food-grade quality, hazardous waste management, a packaging compliance business, and a strong innovation team looking across the whole waste infrastructure.
