PRIME Minister David Cameron has given his seal of approval to a new, state-of-the-art green building in his Witney constituency.

Mr Cameron officially opened the headquarters of Polythene UK in Station Lane, Witney, which has a range of green technology designed to make it totally self-sustaining.

He said: “The new office building is fantastic and I am pleased to hear just how environmentally friendly it is.

“Polythene UK are certainly proving their green credentials and I hope other UK businesses will feel inspired to follow in their footsteps.”

It was a double celebration for Polythene UK’s managing director James Woollard, who recently picked up the Oxfordshire County Council Energy & Environment Award at the Oxfordshire Business Awards.

He said: “It’s fantastic that we’re being recognised for our green efforts.

“Consideration for our impact on the environment will continue to be our main focus from both operational and industrial viewpoints.”

The new 8,000 sq ft office building features a photovoltaic solar system that delivers 22,000 kilowatt hours of electricity per year, air-source heat pumps and rainwater collection butts.

The business also recycles all waste paper, envelopes and empty printer cartridges from its offices.
