The gardening season has just started and we are all hoping for a long and warm summer, which means we will have to water our gardens. Water however is a scarce resource, even in many parts of Europe including the UK. Harvested rain water is free and it takes a little pressure from the main [...]

The debate and the research around ecological materials mainly focuses on re-cycled materials or natural fibres which can reinforce or work in combination with other materials. Some researchers, however, are already working on production processes which will allow materials to be grown in an organic way rather than manufacturing them. The process is based on [...] Combined Heat and Power (CHP) units produce heat and power at the same time. The units normally burn gas, bio-gas or bio fuels and traditionally they are used in industrial set-ups for small scale district heating. The UK based manufacturer Baxi has recently launched a CHP appliance for the home. The appliance’s Free Piston Stirling [...] In 2007 China invested 12 billion US dollars in renewable energies (Germany invested $14 billion and the USA $10 billion) and in the same year 6.4% of the country’s total energy use came from wind power. China’s target for 2020 is to produce 15% of all its energy from renewable sources. With a market share [...] More than 50 % of the world’s population now lives in cities. Cities cover less than 1% of the Earth’s surface, but generate 80% of the world’s CO2 emissions. Housing alone is responsible for nearly one third of the UK’s CO2 emissions and it poses a huge challenge in reducing CO2 emissions. The Larch Garden [...] The United Nations is marking 2010 as the International Year of Biodiversity. The variety of life on Earth is essential to sustaining the living networks and systems that provide us all with health, wealth, food, fuel and the vital services on which our lives depend. Back in 1924 Rudolf Steiner gave a lecture on biodynamic [...] In 2002 each person in the UK generated 167kg of packaging waste per year – a lot of it is glass. In 2001 2.5 million tons of this material was taken to landfill. Currently 752,000 tons of glass are being recycled annually in the UK. Every ton of glass recycled into new items saves 315 [...] Wallpaper is made from a number of different materials and built up in layers. The top layer is normally printed or structured. About 50 per cent of all wallpapers are made from paper or recycled paper, the other 50 per cent is made from fleece and other synthetic materials. The materials used define the quality [...] The cylinder in the office chair recently broke, which means it can no longer be adjusted and seat has sunk to its lowest level. The result is a very uncomfortable sitting position, which is not good for posture and health. What to do? Buy a new chair? Obsolescence is designed into most of our products: flat [...] Maize Cob Boards Organic materials are gaining more relevance in the production of bio-plastics. Rather than growing plants solely for the production of materials, more and more waste products generated in agricultural and food production processes are used for light weight components such as structural panels. One example is Maize Cob Board, which is currently [...] |
