Newly developed methodology for mapping litter is tested

The project, which is financed by Handelens Miljøfond and the City of Oslo, will provide key figures on annual plastic waste from the most important clean-up activities in the City of Oslo. Today, there is no total overview of the littering situation in Oslo, the project will therefore provide valuable insight and data on the amount and type of waste that goes astray through littering, as well as the costs of dealing with these.

Norwaste has developed a methodology for calculating annual amounts of litter that is cleaned up. This is based on mapping cleaned up litter. In order to form a picture of the littering situation, and what is actually cleaned up, the project's first step is to get an overview of the municipality's organization of clean-up work so that the project is adapted to the municipality's infrastructure and systems. Field work will then be carried out where quantities and composition of the litter are mapped.

Examples of "litter streams" that are cleaned up by the municipality are sweeping masses from sweeping cars that clean urban rooms, manually collected litter from cleaning up in urban spaces (parks, squares, etc.) and collected litter from cleaning along roads. Other current litter flows are from clean-up under the auspices of Rusken.
