The prevention of waste is the number one priority in the Dutch waste policy. Prevention is defined as the reduction of the amount (included reuse inside companies) or the hazardness of waste by reduction at the source. The processing of waste leading to a less volume of waste to be landfilled (e.g. incineration) or the reuse of waste is not considered to be prevention. The policy begins to be more and more integrated in other preventive measures as the reduction of energy consumption, the use of water and the reduction of emissions to air, water and soil (cleaner production). The fact that prevention is the number one priority in waste management policy is embedded in the Dutch environmental law and the Dutch National Environmental Policy Plan (NEPP). The implementation of this principle is done in several ways. In this document is described what the experiences are with fixing targets to waste prevention on macro level and on the level of companies.
