3. American scientists have learned how to clear gutters algae
Scientists from rice University in Houston have learned to use algae for purification of municipal wastewater. During the 14 weeks of the experiment, the researchers grew different strains in 12 pools under the open sky.

The thus purified effluent can be discharged into water bodies without harming them.
4. The British first created the dishes from the production waste
English workshop Grandy presented a collection of dishes made exclusively from broken pottery, glass, and stone waste. The firm conducted extensive scientific research, has studied the composition of the clay and glazes that are commonly used in the production of tableware, figured out how to get the right components from the waste.
