Since 1993 has Denmark produced annual waste statistics based on the figures collected through the Danish ISAG system (Information System for Waste and Recycling). The ISAG is based on statutory registration and reporting from Danish waste-treatment plants for all waste entering or leaving the plants. Information concerning waste is reported annually to the Danish Environmental Protection Agency. Information has to be given by 31 January each year for the previous year.

The waste data management system – Information System for Waste and recycling (ISAG) is based on the following preconditions:

  • The waste collector has to be registered with the local authority and has to register information on the quantity of waste being collected, waste fractions, waste types, waste source (geographical and commercial)and where the waste is being delivered. This information has to be delivered to the treatment plant.
  • The treatment plant among other things has to register information on quantity, geographical source, commercial source, waste type and treatment. EWC codes has to be used on dangerous waste.

All treatment plants are reporting to ISAG, which means that all waste produced in Denmark is being registered (no system is perfect but nearly all waste).

This also means that Denmark does not distinct between waste generation (according to WstatR annex I) and waste treatment (according to WstatR annex II), as the Danish ISAG system only focuses on waste being treated. But ISAG covers all waste treatment plants for which reason all waste being generated is covered by the system.

ISAG also has a way to avoid double counting. In reporting to ISAG treatment plants have to distinguish between waste from direct (primary) sources and waste from plant (secondary) sources.

Currently, Denmark is working on a new Waste Model. The purpose of this model is among other things to provide improved data on waste in Denmark.

The ISAG will still be the starting point of the new Waste Model.
