Scientists have developed system of economy of water
Baku, January 7 (AZERTAC). The American scientists have seriously reflected on preservation of natural resources in global sense and in the country in particular.
For preservation of water resources the scientific USA not only work on workings out of technologies of minimisation of use of water in all branches of modern manufacture and human life, and also scientists want to clear consciousness in people and them to educate them in water expenses. Scientists suggest to enter system of marks of products which will specify how many water has been spent for manufacturing of this or that product that will influence the consumer and in the future all will try to save water. Thus, the American consumers have already learnt that for preparation of morning coffee 140 litres of water are spent, for a cup of tea 30 litres of water in a production cycle are used.
Also on packing with rice it will be possible to find a note that for manufacture of rice of 1 kg was 3 400 litres of water, and for kg of wheat of 1 300 litres of water are spent, for manufacturing of beef of 1 kg manufacturers had been spent 15 500 litres of water. Such system of marks of products is entered to provide deeper understanding and awareness on used volumes of water on all planet. The agriculture is the heavy user of fresh water in many countries of the world. Working out of new system of economy of water will help to keep water resources, especially this subject is actual in the present and the near future as under forecasts of experts the planet population by 2050 will increase to 9 billion persons, informs news agency "Kazakh-grain".
The Similar program was already spent, but only with a view of conservation of energy. The system «Energy Star» is the international standard for an energy effective utilisation in house or industrial conditions. This system has been developed in the USA within the limits of the program on preservation of the environment in 1992.
