Green water-purification system works without heavy metals or corrosive chemicals

Added: 14.02.2019 18:23 | 8 views | 0 comments

Scientists have developed an effective and energy-efficient technique for purifying water by using graphitic carbon nitride sheets. Their prototype purified pathogen-rich water in 30 minutes, killing over 99.9999 percent of bacteria, such as E. coli, meeting China's requirements for clean drinking water.


Millions of tons of plastic waste could be turned into clean fuels, other products

Added: 14.02.2019 18:23 | 4 views | 0 comments

A new chemical conversion process could transform the world's polyolefin waste, a form of plastic, into useful products, such as clean fuels and other items. The conversion process incorporates selective extraction and hydrothermal liquefaction. Once the plastic is converted into naphtha, it can be used as a feedstock for other chemicals or further separated into specialty solvents or other products.
