Sludge production continues to increase, and the total market size continues to increase
As a byproduct of sewage, sludge production has also been increasing in recent years. In 2015, national sludge production was approximately 35 million tons, a growth of YoY16% . In municipal industry, it is estimated that about 10 million tons of sewage will produce 5-8 million tons of municipal sludge. It is estimated that China produces 30 million to 40 million tons of municipal sludge with a water content of about 80% per year.
The policy requires that the harmless treatment rate of sludge reach 90% in 2020
According to calculations, China's sludge production will reach 74,624,300 tons in urban areas by 2020. The "Water Ten" issued in 2015 requires that the existing sludge treatment facilities basically complete the standard transformation by the end of 2017, and that the harmless treatment rate of municipal sludge at or above the prefecture should reach 90% in 2020. It is expected that the investment in new sludge treatment equipment will reach 50-60 billion yuan, creating a huge market for sludge treatment and disposal!
Inefficient treatment and disposal methods still dominate the market and have high potential for resource utilization
"Paying attention to sewage treatment and ignoring sludge treatment" is a common phenomenon in China's municipal sewage treatment industry. Thousands of tons of sludge are often treated improperly. According to research by Water Research, up to half of the sludge in China is landfilled, which is an inefficient disposal. The sludge is not being properly used as a resource. We should pay great attention to the immense potential of advanced sludge treatment.
The investment funds for sludge treatment are limited, so it is a huge prospect for bringing economic benefits by resource utilization
In developed countries, nearly 50% of the sewage treatment investment is spent on sludge treatment. In Japan, where environmental treatment is highly developed, the disposal cost of 1 ton of sludge can even be as high as 800 yuan. However, in China, sludge treatment accounted for only 8.8% of investment in sewage treatment in the last “12th five-year plan”.
