Instead of flushing water through the school urinals every fifteen minutes, schools now have the option to install eco-cubes in their washrooms to better and more sustainable effect. The eco-cube uses a combination of lime scale, uric scale and ammonic salts to keep the urinal or trough smelling clean and scale-free without a drop of water. Normally urinals use 151,000 liters of water per year each, so this represents a considerable cost and environmental savings. Doesn't involve any modifications, either: just drop it in and turn off the water. [GT]
