Britain's housing industry should learn from University of Brighton research and use recycled "rubbish" in construction projects, according to Brighton Green MP Caroline Lucas.
On a visit to the university's Waste House – the country's first building made almost entirely of thrown away materials – Ms Lucas said: "The housing industry is decades behind where best practice is and I think the real challenge of this Waste House is for it not to be seen as a one off example but actually to be paving the way in what has to be mainstream.
"This is the way we are going to have to build in the future if we are serious about living within the resources of one planet earth."
More than 20,000 old toothbrushes, two tonnes of denim jeans, 4,000 video cassettes, 2,000 used carpet tiles, thrown away timber, paper, plastic bags and chalk, were used in the house construction at the university’s Grand Parade campus in Brighton.
Ms Lucas said: "The housing industry has a huge amount to catch up on. For every five houses currently being built enough waste is created to build one extra house – most people understand that this makes absolutely no sense at all.
"The housing industry has got to get its act together."
