I thank my hon. Friend for his follow-up questions. Several colleagues have raised the issue of cost being calculated by weight and not by unit, but waste management costs are largely driven by weight. We have taken into account other factors that influence collection costs, including the estimated volume of each material in bins and collection vehicles. Glass is a heavy material with a low resale value. A unit of glass packaging costs more for a local authority to manage as waste than an item made up of more lightweight and high-value material. Our recycling assessment methodology changes are published on defra.gov.uk, so people can see the changes that we are proposing to bring in next year and how we are ramping up the fees payable for less recyclable packaging. Reuse and refill of packaging provides a real opportunity for economic growth and job creation. Earlier this year, GoUnpackaged produced economic modelling that made a compelling case for scaling up reuse in UK grocery retail. That work showed end-to-end system cost savings of up to £577 million a year, highlighting the economic viability of reuse in the UK. In response to that research, major grocery retailers have committed to working together to scale reusable packaging systems. Innovate UK has commissioned a scoping study to develop the blueprint for the first wave of this bold multi-retailer reuse scheme, so change will be coming in this sector pretty fast.
