Comfort is a bacteria chair
This article describes a method of making a sort of wood composite out of the sludge from waste water plants. A good idea. One of those that may turn out to be more expensive than it is worth. Even though there are some spot crisis areas where tree harvesting is a problem, wood is still awfully cheap.However, this is another support in the trend of new materials. In a few years we will not be able to recognize what some stuff is even made from.
Also, a nice green technology. Good for cities.

Wastewater purification uses microbes to form unwanted carbon, nitrogen and phosphorus into a cell mass that settles out, but the disposal of the material can cause greenhouse gases.
The team has found a way to prompt the bacteria to grow small granules of plastic within the cell mass, a substance that can then be mixed with natural fibres like straw, wood or hemp to create a wood-composite.
Dr Frank Loge, leading the research at University of California at Davis said the wood-composite has identical properties to conventional materials made using oil-based plastics. ‘The cell mass does make the wood-composite a little bit more flexible however,’ he said. ‘It’s a property we’re not used to getting out of these materials.’ The material would also be biodegradable, thus restricting it to indoor applications such as furniture, doors or interior building structures.
