The environmentally friendly bricks developed by Liu Hengli save energy without polluting the air, and were selected as the best environmental invention of the year by Time Magazine. (U.S. "World Journal") According to the U.S. "World Journal" report, the environmentally friendly bricks developed by Henry Liu, a retired Chinese professor at the University of Missouri in the United States, were selected as "Time Magazine" because they are low-pollution, energy-saving, and can even purify the surrounding air. 》(Time) Best Invention of the Year in the Environmental Category. Liu Hengli's environmentally friendly bricks (GreenBrick) are basically products made from waste. He said that fly ash (Ashes) is produced when power plants burn coal. According to estimates, U.S. power plants produce a total of about 70 million tons of fly ash a year, of which only about 25 million tons are recycled and reused, and the rest are recycled. Dispose of as landfill. Liu Hengli saw the value of these fly ash, so he developed the idea of ??using a compressor to compress the fly ash into bricks. In the process, there is no need to go through the high-temperature combustion process of traditional bricks. This not only saves fuel, but also reduces air pollution and avoids the greenhouse effect. Meets the environmental protection requirements of modern society. Liu Hengli's environmentally friendly bricks not only have the same appearance as traditional bricks, but are even better in pressure resistance and cold resistance, and are also cheaper than traditional bricks because they save the energy required to burn bricks. He said that the most special thing is that environmentally friendly bricks can absorb toxic chemicals such as mercury in the air and purify the air. Liu Hengli, who graduated from the Department of Civil Engineering at National Taiwan University, received a postdoctoral degree from Colorado State University and began to serve as a professor in the Department of Civil Engineering at the University of Michigan. Later, he also served as the director of the "Freight Pipeline Research Center" at the University of Michigan. In 2001, he retired from the University of Michigan and decided to start a second business. He established the "Freight Pipeline Company" in Columbia, Miss., and continued to engage in research on freight pipelines. He applied the principle of pipeline compression transportation to the compression of coal ash bricks, and finally Successfully developed bricks that are environmentally friendly and cost-effective. Since Liu Hengli developed the environmentally friendly bricks, he has continued to receive praise. In June this year, Popular Science magazine included Liu Hengli's environmentally friendly bricks among the 10 best inventions of the year. Liu Hengli is currently applying for patents in the United States, China, and the European Union for environmentally friendly bricks. Investment companies and power plants in eight countries, including Australia, South Africa, and Brazil, have contacted him, hoping to cooperate in production. Do you know who I am
