Problem:
Water is an increasingly precious commodity and many washing machines still require large amounts for washing/rinsing as well as the use of chemicals harmful to the environment.
Solution:
Detergent-free clothes-washing machine.
In 1924, when firms such as the Savage Arms Corporation of New York presented the electrically-powered wash/spin-dry clothes washing machine to the world, neither its energy and water consumption, nor the harmful effects of chemical detergents on the ecosystem, were taken into account. Today, the eco-efficient bio washing machine has become of primary importance.
There have been many developments. Japan Ace, based on research at Nihon University produced a detergentless, ultrasonic bubble-cleansing domestic washing machine in 1985, but the main breakthrough was made by Stephen Burkinshaw at the University of Leeds focusing on the structure of nylon polymer beads.
He discovered that nylon was the best material for absorbing tiny particles, and together with his team of researchers came up with the concept of using nylon polymer beads to remove stains from clothes.
When the wash cycle is completed, the beads automatically return to a holding area inside the machine and are ready to be used again for the next wash. These beads can be used for up to a thousand washes and are then collected to be recycled and exchanged for new one.
From 2009, Burkinshaw and his team collaborated with Stephen Jenkins and William Westwater at Xeros Technologies in Catcliffe, South Yorkshire, England to commercially produce the beads which they called XOrb and a 55 lb (25 kg) capacity waterless washing machine by the end of 2011.
According to Xeros, its technology uses 90% less water than the conventional washing machine. While a conventional front-loading washer uses about 20-25 gallons (75-95 liters) of water, the Xeros Washing Machine is estimated to use as little as one gallon of water.
The machine is also projected to save consumers up to 30% for operating costs in electricity and water. Xeros then presented their XDrum technology to other washing machine manufacturers. Hotel groups such Hilton, Hyatt, or Hampton Inn acquired Xeros to wash their laundry.
In March 2018, Xeros acquired Gloves Inc., providing personal protection equipment cleaning, inspection and repair services in the Miami metro areas.
At CES 2018, Xeros unveiled XFiltra to go with XOrb and XDrum technologies XFiltra is designed to help capture the synthetic fibers from fleece and other clothing that are making their way from the wash into oceans. Appliance makers would still have to design around the pump and filter.
The biggest commercial washing manufacturers in China and India both signed up, while Dongguan Crystal Knitting and Garment, a subsidiary of Crystal International Group, the world’s largest apparel maker by volume, are trialling the technology.
In 2019 Xeros signed up with Indian home appliance manufacturer IFB Industries Ltd. in Kolkata to make and sell X technology in India by from 2020-2021. Xeros, a platform technology company that works on reinventing water intensive industrial and commercial processes, believes the reason the Indian market is important for its water-saving technology is that the country is under extreme water stress.
According to the NITI Aayog, more than 600 million Indians face acute water shortages. The Xeros tech can also save water in the tanning industry and, having entered the market itself, Xeros signed a deal which will see at least one Mexican producer convert its re-tanning operations.
