Recyclable waste
This research only includes recyclable waste, since it has a value and therefore generates money when sold. This mainly applies to thermoplastics, which soften when heated, e.g. packaging materials. There is also waste which does not generate any money or for which money is paid.
Aside from recyclable waste, there is also mineral waste and waste from the food industry, used in the manufacture of animal feed for example. These waste types are not included in this research. The research is based on a list compiled by Eurostat: the List of CN-codes used for indicator calculation. These indicators are referred to as Waste Management Indicators (WMI).
