Conserve water: Xeros washing machines should be compulsory

In Environment on 09/10/2018 at 7:42 am

In view of the PAP govt’s attempt to reduce water consumption, Xeros washing machines seem to juz the thing for S’pore.

After you put in your laundry, the drum adds about 23,000 small polymer spheres – which the company calls XOrbs – with a total weight around 6kg, plus a cup of water and detergent.

The spheres absorb the stains, then get collected through the drum, and afterwards are stored behind it to be reused next time.

The household machine uses 50% less water than a conventional washing machine, while the commercial version, which uses 70,000 spheres weighing 20kg, uses 80% less.

Other interesting ”save” water products.

Unilever

has produced a spray called Day2 that works like dry shampoo, designed to refresh those clothes that lie around on the floor on on the back of a chair but aren’t really that dirty at all.

Also

Swiss start-up Dolfi has come up with a device that cleans delicate fabrics using ultrasound to agitate a small amount of water and detergent.

And there’s this

Despite its misleading name, the dry cleaning industry also uses a lot of water – used in the form of steam – not to mention potential carcinogens like the solvent perchloroethylene, or perc for short.

But in the last five years, technological improvements have meant water and biodegradable detergents and conditioners can clean “dry clean only” garments made from wool, silk, or suede, says Nick Harris, managing director of VClean Life.

VClean recently launched a “wet cleaning” factory in Watford, Hertfordshire, that “weighs clothes and works out exactly how much water is necessary”, says Mr Harris.

And the boiler water used to make steam is recycled.
