One of the biggest criticisms levelled at industrial and commercial decision-makers is that not enough is done to prevent waste in the first place. Waste minimisation is about waste prevention or reduction at source. With such a definition it can equally apply to industry and householders. Waste minimisation, particularly for solid and liquid wastes, is seen to be a key element of sustainable development. It is clearly stated (DETR 1998) that: “the simplest and most effective way of dealing with waste is to ensure that it does not arise. The Government wants waste minimisation and reuse to be an important focus of the strategy. Up until now waste minimisation has taken place within industry and commerce. The new waste strategy will address whether and how to expand and develop such measures, and will consider how waste minimisation for households can be encouraged.'
