Struggling to tell your waste from your by products and your recycled from your recovered. This Defra guidance is aimed at businesses and other organisations which take decisions on a day-to-day basis about whether something is or is not waste. In most cases, the decision is straightforward and whoever is taking the decision does not need guidance from the competent authorities to help them take it. However, in some cases, the decision is more difficult (e.g. where the substance or object has a value or a potential use or where the decision is about whether waste has been fully recovered or recycled and has therefore ceased to be waste). The aim of the guidance is to help ensure that the right decision is taken in these more difficult cases.
