California-based Soil Retention is behind a product, Drivable Grass, that many of you may be interested in. The name is somewhat of a misnomer, because, as you will see below, the infill doesn’t have to be grass. It can be gravel of various kinds, too. Drivable Grass is a flexible product that can be used as a substitute for concrete and asphalt driveways, patios, parking lots, RV pads, boat ramps, and the like.
You’ve probably already seen this toilet and sink combination before. It’s the W+W – short for washbasin and watercloset – from Roca. The product, currently available overseas, reuses waste water from the sink in the discharge of the cistern, which helps it reduce water usage by up to 25% compared to a standard 6/3 liter dual-flush toilet.
Water efficiency is an important measure in green building everywhere, but in Australia — one of the driest countries in the world — water conservation is more widely practiced and water awareness is generally higher than it is in North America. In addition to pioneering water efficiency, Australians have discovered some problems due to the use of efficient, low-flow fixtures. One is the potential problem of "dry drains," however, a new invention called the Drainwave aims to solve the problem.
