How do you judge whether a product has a high or low impact on the environment?
Some manufacturing companies may decide that if a product contains biodegradable surfactants or has a neutral pH, it is sufficient justification to make such claims. If a highly active neutral product is used undiluted, how does this compare with an alkali product that is diluted 1 part to 100 parts water?
There are various schemes used in Europe to determine environmental impact but none takes into account all of the relevant factors.
For this reason one of Evans’ experienced research chemists, Sandra Wright, devised a unique system for assessing the overall environmental impact of a product, taking into account the formulation, manufacture, use and disposal of the product. We have called this scheme the ‘Wright Environmental Impact Rating’ (W.E.I.R.) scheme.
