Note: the Berkeley Group introduced an online waste data management system (Qflow) for its 2024/25 reporting. This has led to the below data improvements which should be noted when reviewing present and historical figures:
- Waste weight: in all instances prior to 2024/25, conversion factors were used to translate waste container volumes extracted from waste transfer notes to mass figures. From 2024/25, the online data management system has enabled accurate reporting of mass data based on weighbridge information where available from our contractors. Where unavailable, volume to mass conversion factors continue to be used.
- Waste destination: prior to 2024/25, waste destination reporting was based on the facility type of the initial waste destination. For material recovery facilities (MRFs), a consistent recycling / recovery rate was applied based on the average rate from a sample of MRFs used across the Berkeley Group, with remaining wastes presumed to be taken to landfill. Due to the high variability of recycling / recovery rates for hazardous waste treatment facilities, all waste taken to such facilities was presumed to be taken to landfill. From 2024/25, the online data management system enables more accurate reporting of waste destinations, with facility specific reuse, recycling, recovery and disposal rates applied to each waste transfer based on the facility’s waste returns submitted to the Environment Agency (EA).
