Committed to the Environment
We continually address environmental issues associated with this industry. We are always aware of our duty to maintain the very highest standards of conformity at all times and so work closely with local and national regulatory bodies.
The European Union's "end-of-life" vehicle (EOLV) directive in 2000 resulted in the elimination of harmful hexavalent chromium in automobiles. The major consequence of this was that traditional "zinc with yellow chromate" used extensively in the automotive industry was eliminated. We adopted non-hexavalent chromium processes that use passivates which give superior corrosion protection and was the start of our journey to longer life greener coatings.
NZG were the first zinc electro plating company to be awarded a full IPPC permit – Integrated Pollution Prevention and Control – from the Government Agency DEFRA, leading the way to a safer and cleaner environment.
NZG at all times constantly review materials and chemicals utilised in our processes to minimise our impact on the environment. We reduce waste produced and recycle. We were the first UK coatings company to adopt total green chemistry.
