New Toilet Turns Waste into Electricity and Fertilizer

According to a recent Science Daily article, researchers have invented a new toilet system that turns human waste into electricity and fertilizers. It also reduces the amount of water needed for flushing by up to 90 percent compared to current toilet systems. Dubbed the No-Mix Vacuum Toilet, it has two chambers that separate the liquid and solid wastes. Using vacuum suction technology (i.e., aircraft lavatories), flushing liquids would now take only 0.2 litres of water while flushing solids would require just one litre. Existing conventional toiles use about 4 to 6 litres of water per flush.
