The WRAP commercial and household waste/recycling ‘apportionment tool’ assists local authorities to calculate the proportion of waste and recycling when it is co-collected on the same vehicle.
- Provide consistency in the approach used by local authorities to apportion tonnages
- Improve the accuracy of data
- Assist with budgeting and service development
The tool was developed in conjunction with a steering group which included representatives from NAWDO, Larac, Defra and the Environment Agency/Natural Resources Wales.
It has been designed to be simple to use, local authorities only need to input how many bin lifts are made - by size and material type.
The tool was tested by comparing it with actual dedicated round data which showed that it produces results which are not statistically different.
A user guide is available to support the use of the tool.
