3 innovations to conserve and recover water

3 innovations to conserve and recover water

The search for solutions to this urgent crisis has intensified from all areas of society. These are 3 innovative solutions, which are a source of hope for a supply ofclean water and safe globally.

A great Pacific cleanup

TheTrash Island, called in English: Pacific Garbage Patch is a waste vortex in the middle of the Pacific Ocean that has led to ideas such as The Ocean Cleanup or the seabina in recent years, an innovative bucket to clean the oceans.

The first was an initiative of the Dutch 21-year-old Boyan Slat who created this venture in 2015 with the intention of cleaning the garbage from the Pacific Ocean, by using a floating screen to collect the waste and then send it to “mainland” to to berecycled.

Tests are under way with a facility that was placed in the North Sea in June last year, which is 100 meters long and the Pacific Garbage Patch is currently being studied in greater detail, to make itend technology be as effective as possible.


More clothes, less water

A jeans and cotton T-shirt may seem like simple everyday garments, but behind their production there is an uncomfortable truth: making a T-shirt can consume 2,700 liters of water and jeans another 10,000 liters more.

Clothing companies realized that theintensive use of waterit undermines their own long-term access to this natural resource and they are developing innovative forms of production, with less use of water.

The American brand Levi’s, for example, has a finishing technique called "Water Less", which uses 96% less water than traditional methods. They are also tryingRecycle used cotton clothing, in new fabrics.

Large sportswear manufacturers such as Adidas and Nike dye their polyester fabrics almost dry-dye and the Dutch company DyeCoo usesliquid carbon dioxide for the same purpose.

Sea water for greenhouses

In an attempt to transform some of the most arid areas into fruit and vegetable farms, scientists around the world have developed ways to convert seawater to freshwater usingsolar energy.

Water is pumped from the sea and drips onto a honeycomb structure inside a greenhouse, where it evaporates, then cools down andcondenses like fresh water, in the roof. Such facilities already exist in the Sahara, Jordan and Tunisia, as well as the Sundrop farm in South Australia.
