Dual flush toilet technology and waterless washing machines can help save water. Dual flush toilets allow users to choose between a full or partial flush depending on waste. Waterless washing machines use plastic granules instead of water to remove stains, saving over 455 million liters of water. Xeros washing machines in particular use nylon beads to clean clothes with only dampness, using far less water and detergent than conventional machines. They can help reduce electricity and costs while providing environmental benefits such as lowered CO2 emissions.
