News that the first UK straw bale houses have gone on sale near Bristol (http://www.bbc.co.uk/news/science-environment-31156579). These have the advantage of providing excellent insulation and the waste material used to build them removes carbon dioxide from the air. It has been estimated that enough waste (not required for animal bedding) straw is produced in the country each year to build 500,000 homes. What is not mentioned is that the traditional alternatives (brick and cement) produce carbon dioxide making climate change more likely!
