The next outlet for solid waste treatment - construction waste mentions three "gift packs"

release date: Source: environmental protection

"if the construction waste is only treated by stacking or landfilling, it will not only seriously affect the urban landscape, but also occupy the land and pollute the soil, air and water" the industry generally holds this attitude towards construction waste

figures released by the Ministry of housing and urban rural development show that China's annual new construction area will reach 2billion square meters. By 2020, China will build 30billion square meters of new houses, and the resulting construction waste will reach at least 5billion tons. The construction waste has accounted for about 40% of the total amount of municipal solid waste

in fact, China has been promoting the treatment of construction waste in recent years. Data show that from 2010 to now, a total of 10 provinces and 167 regions in China have issued policies on construction waste management. However, in the face of the huge amount of construction waste, the utilization rate of construction waste in China is not high. There are only about 70 production lines with an annual disposal capacity of more than 1million tons of construction waste that have been put into operation and are under construction. There are hundreds of small-scale disposal enterprises, with a total resource utilization of less than 100million tons

it can be seen that there is still a long way to go for China's construction waste treatment, especially in the context of waste reduction and recycling

according to the current situation of the environmental protection industry, construction waste treatment will also usher in three opportunities

multi department linkage "interconnection +" promoting management

some experts pointed out that the resource utilization of construction waste is a systematic project, involving production, transportation, treatment, reuse and other aspects, which requires the cooperation and effective linkage of multiple administrative departments such as construction, urban management, industry and informatization, and the national development and Reform Commission. At the same time, China should also improve the special legislation on the resource utilization of construction waste, strengthen the construction of administrative law enforcement team, and extend to multiple links for the whole industry chain management

speaking of management, in the "Internet +" era, it is also very important to establish joint management of 8000 square feet of construction waste. Through the IOT management platform, all localities can realize the scientific layout of resource utilization facilities, reasonable selection of transportation routes, and the implementation of perfect classification and collection system, which will play a very important role in reducing disposal costs and standardizing the management of all links

In 1993, Professor chenjialong proposed a research project on the recycling of construction waste and set up a scientific research team. Starting with the recycling technology of construction waste, he has produced recycled hollow blocks, recycled coarse and fine aggregates and other construction raw materials, which have been used in construction projects in Beijing, Hebei and other provinces. In addition, the two achievements of "common key technologies and industrialized application of construction solid waste recycling" and "key technologies and engineering application of waste concrete recycling" won the second prize of the national science and Technology Progress Award in 2018

in January, 2019, the common key technologies and industrialized application of building solid waste recycling jointly completed by Tongji University, Beijing Architecture University, Qingdao Institute of technology, Beijing Lianlv, Kunming Institute of technology, Shanghai Shanmei, Xuchang Jinke, etc. won the second prize of the 2018 National Science and technology progress award

in 2020, the key project 202 of "solid waste recycling" of the Ministry of science and technology included the key technology project for the recycling and utilization of waste concrete sand powder for the first time in the 0 year project application guide along with the mediation, elimination and upgrading of household property under economic stress of the people, such as aerospace, national defense, kerosene chemical industry, transportation, etc

to sum up, the technical base related to construction waste treatment has been continuously filled, providing a persistent support for the follow-up development

ppp project construction waste to be released is the next outlet

environmental protection projects are becoming the hotspot of PPP. According to the data, by the end of May, the reserve list projects with a total investment of 3.6 trillion had not yet entered the management library, which means that PPP still needs to be further expanded in terms of the number and scale of projects. The new sewage and waste treatment projects participated by the government need to fully implement the PPP model process. There has been a major turning point in the development process of measurement and control instruments. The main contrast is the opportunity of product quality and precision, which has gradually transitioned from the previous stage of reconstruction and light operation to the stage of heavy operation

since the construction waste was first selected into the second batch of PPP demonstration projects of the Ministry of Finance in 2015, the third batch and the fourth batch have also been included in the construction waste projects. Although there are only 15 utilization projects in the implementation stage of construction waste PPP projects, the early inclusion of construction waste PPP projects has provided a replicable and popularized implementation example

some professionals said that for the current construction waste projects, although they have not been warehoused, they usually have signed franchise agreements with local governments, locking in stable disposal subsidy income. With the standardization of later projects on the right track and the possible opportunities for the organic combination of PPP and special debt, PPP for construction waste will usher in new vitality in the future
