Clean fuel, waste air processing, bio fertilizer, eco-protection science and technology, Internet+ eco protection cloud and eco protection products and solutions made its debut in the 7th Green Industry International Fair (Green Fair) held recently.

    Clean fuel is the 1st choice for management companies to enter the eco-protection industry in energy-saving and emission-reduction era. In the fair, a Qingdao company showed a clean fuel – coal water slurry, which is a kind of clean, high efficient and clean transportable coal-based fluid fuel that is made up of 65% coal and industry and life wasted water, as well as ingredients. According to company officials, water coal slurry washes traditional coal to reduce 30%-40% of sulfur to guarantee the coal is clean. Meanwhile, slightly alkaline wasted water produced by the company can be used in making water coal slurry, thus Reducing Waste by Utilizing Waste concept can be realized.

    Small size bio integrated processing device showed in the fair can dam, absorb and resolve living wasted water by using micro-biological degradation principles. It is a kind of new rural living wasted water processing device enables to purify wasted water and recycle it. It attracts many potential buyers for its low cost, long service life and recycled use of wasted water. Company employees said: “360,000 tons clean water can be free of polluting every year by using this eco protection toilet. Compared to traditional ones, more than 1,000 tons water can be saved each year, which means over CNY 4,000 water bill, and over CNY 6,000 cleaning fee.” It is known that the technology is adopted in green toilets in the Qingdao Olympics Sailing Center and World horticultural expo park, and it will be used in toilet reform work in rural area of Laoshan district, Chengyang district and Pingdu district.
