Commercial and household waste/recycling apportionment tool

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. It also aims to:
• provide consistency in the approach used by local authorities to apportion tonnages
• improve the accuracy of data
• assist with budgeting and service development

“Using the tool to collate an accurate outcome of a new recycling site is now much easier than without it.  Prior to access to the tool we would have had to collect the recycling bins separately and take them to the weighbridge to gain a figure we could then multiply by the collections over a year.  This of course was time consuming, an expensive use of resources and not environmentally friendly.”
Erewash Borough Council

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.
