The silt of the reservoir has been transformed into the promised land of Taiwan! From anti-wall cancer building materials to flower ware tea plates, emitting a Nordic simple style.

The water storage capacity of 96 reservoirs across the country is 2.84 billion tons, 1/3 of which are actually filled with sand and gravel, and the siltation capacity is increased by one reservoir a year. The silt that has been cleared has nowhere to go. Taiwan's largest silt storage site in Shimen Reservoir, which has 3 million tons, is already in a state of full load. as soon as the heavy rain comes, the silt will flow back to the reservoir, seriously affecting the water storage function of the reservoir.

The seemingly useless sludge actually has great potential. The successful university team innovated and upgraded the sludge into innovative building materials that can prevent wall cancer and waterproof, and can also be used in life decorations such as flower growers and tea trays. This innovation has been patented and named "promised Land", successfully transforming the fate of "wasteland".

The geology of Taiwan is young, the mountains are high and the water is urgent, the slopes of the rivers are steep, and the rainfall is three times that of the world average, but there is not much water retained. Torrential rains washing away a lot of sand and gravel has become a nightmare for water conservancy units.

When Typhoon Eli hit northern Taiwan in 2004, soil and rock erosion caused the Shimen Reservoir turbidity to increase and the water purification plant could not operate. Taoyuan was forced to stop water for 18 days, and people were holding basin buckets to pick up water everywhere. The massive water stoppage disgraced the water conservancy units, seriously damaged the myth of water control, and a large amount of silt even affected the life of the reservoir.

In 2009, Typhoon Morakot brought nearly 100 million tons of sludge, leaving only 40% of the largest Zengwen Reservoir in the south. The sand and stone dug out by dredging in the reservoir belong to valuable materials and are quickly carried away. However, priceless materials such as silt and hydrous clay are difficult to transport, so they can only be piled in the open air around the reservoir and have nowhere to go. As soon as the heavy rain came, the mud followed the current back to the reservoir.

Reservoir desilting is regarded as a headache by water conservancy units, with an annual deposition of 18 million tons, which is equivalent to the water storage capacity of a reservoir. _ taken from the electronic report of the Ministry of Economic Affairs, the reservoir sludge was modified to produce nano-waterproof effect and won the national patent.

After the water shutdown in Taoyuan, all units tried to remove the silt from the reservoir. At that time, the Council for Economic Development (now the National Development Commission) commissioned Professor Huang Zhongxin of the Department of Civil Engineering to study the application of silt in the reservoir to develop the feasibility of desilting the reservoir and create utilization value to remove the silt.

The R & D team found that the general river silt impurities are difficult to deal with, and the reservoir silt is relatively clean and easy to deal with, so it has application potential. The silt is derived from shale which has been scoured by rivers for thousands of years, and the fine viscosity of the particles is high. after a special procedure to change the physical properties, it can produce a waterproof effect similar to that of nanometer. Compared with the high price of traditional nano materials, the modified sludge can greatly reduce the material cost and produce commercial application value.

How does the sludge with "high viscosity and small particles" become "nano-like"? Huang Zhongxin, for example, slips easily after absorbing water, because the water runs into the cracks in the particles, and after special chemical treatment, the water is separated from sliding.

This silt modification technology has successfully obtained a national patent. Huang Zhongxin says that it is a local building material that integrates local natural conditions and reverses the plight of water conservancy, and is worthy of the pride of the Chinese people.

Guo Wenyi, a student of Huang Zhongxin, participated in the whole process from the research and development of sludge quality improvement to technology transfer. In order to make the sludge produce the application value of the industry, Guo Wenyi established "Chengda Chang Hong" through the authorization of the Technology transfer Center of Chengkung University. This is Chengda's first "derivative company", which specializes in promoting the application of sludge quality, from production, brand to market development.

Guo Wenyi knows very well that it is difficult for new technologies to break into the top of the construction industry of large groups. In the past, it is not that there is no improved material to enter the market, but the existing technology model and interest structure are difficult to change, so it is necessary to find another way. He chose a difficult but longer-term way to enter the market from consumers at the bottom of the pyramid.

"large enterprises are United fleets, and they can be closed and ignore the changes outside. We are not the first to reuse silt, and the engineering and construction industry is not easy to innovate, and the larger the group system is, the more difficult it is to change, so we have to develop the market on our own. "Guo Wen-Yi believes that if the network provides a new path, it will break through from the consumers at the bottom and open up a market gap.

Guo Wenyi gave the modified mud a playful name, "Happy Land," hoping that the application of the new material would create fun in life. in order to collect users' opinions, Guo Wenyi's team went from blogging to developing Facebook clubs, exchanging experiences on wall cancer and life applications, creating a discussion community, and shooting their own Youtube teaching videos to set up communication channels.

"it just so happens that modern people like DIY and start their own lives, so we will provide this material for consumers to share all kinds of application experiences and open up a community model for common learning."
