Having been tested and tried many times, some waste incinerators at Lalie town in Du'an Yao autonomous county in Hechi started a pilot run on July 12.

They passed national standards with lower exhaust emissions.

Zhu Xiaozhou, the inventor, is nearly in his sixties. He is fond of mechanical design and holds a state patent for the concrete mixer he invented at the age of 30. He set up a machinery factory to produce farm tractors in 1990, which were rated as famous brand high-quality products of Hechi. He became a renowned entrepreneur and his career took off.

With the launch of the project "Beautiful Guangxi, clean village", Zhu had a mind to invent a highly -efficient environmentally-friendly waste incinerator. At the beginning of 2014, he finished the assembly procedure. After six months of testing by the State Intellectual Property Office of Nanning, Zhu finally received a Utility Model Patent Certificate on June 17, 2015. The incinerator was recognized and praised by the Du’an government for its high efficiency and low energy consumption.

Despite his success, Zhu continued seeking a more environmentally friendly way to dispose of rubbish. Up to now, he has obtained seven certificates of green invention patents, including three environmental waste management patents and four utility model patents. He is sure that the waste fired incinerator, combining two patented technologies, will bring benefit to the project "Beautiful Guangxi, clean village".
