In order to win the battle of pollution prevention and control, deepen the supply-side structural reform of the wall material industry, and promote the high-quality and green development of the wall material industry, recently, the Jiangsu Provincial Department of Industry and Information Technology, the Development and Reform Commission, the Department of Ecological Environment, the Department of Housing and Construction, and the Market Supervision Bureau jointly issued the catalogue of new wall materials in Jiangsu Province (2019 copies) and the development orientation of wall materials industry in Jiangsu Province (2019 copies) (hereinafter referred to the industry).
In order to win the battle of pollution prevention and control, deepen the supply-side structural reform of the wall material industry, and promote the high-quality and green development of the wall material industry, recently, the Jiangsu Provincial Department of Industry and Information Technology, the Development and Reform Commission, the Department of Ecological Environment, the Department of Housing and Construction, and the Market Supervision Bureau jointly issued the catalogue of new wall materials in Jiangsu Province (2019 copies) and the development orientation of wall materials industry in Jiangsu Province (2019 copies) (hereinafter referred to the industry).
In recent years, ecological and environmental protection has been paid more and more attention. The state and provinces have put forward new requirements for speeding up the elimination of backward brick kilns with serious pollution, promoting industrial transformation and upgrading, encouraging the development of prefabricated buildings, and promoting the application of new wall materials such as waste and waste. The original "Product Catalog" and "Industry Orientation" can no longer meet the requirements of the current situation. For this reason, they have been revised and improved on the basis of repeated solicitation of opinions.
In order to implement the requirements of the "Three-Year Action Plan for Jiangsu Province to Win the Blue Sky Defense War", the revised "Industry Orientation" will replace "28-door and below wheel kilns, vertical kilns, Roof-less wheel kilns, horseshoe kilns, etc." with "wheel kilns, vertical kilns, Roof-less wheel kilns, horseshoe kilns, etc." in the eliminated and backward production processes and scales "; the encouraged category adds content such as the consumption of concrete blocks (bricks) using local construction waste as recycled aggregates. At the same time, according to the "Guiding Opinions on Vigorously Developing Prefabricated Buildings" of the General Office of the State Council, the "Product Catalog" added 11 varieties of prefabricated wall panels (bodies).
Regarding how to implement the new "Product Catalog" and "Industry Orientation", the five departments also put forward specific requirements: First, we must accelerate the optimization and upgrading of the wall material industry, resolutely eliminate backward production capacity such as brick and tile wheel kilns, and encourage the development of new types of waste. Wall materials. The new wall material products shall be produced by the production process, production scale and production raw materials above the restricted category; the green wall material products shall be produced by the production process, production scale and production raw materials of the encouraged category. Second, we must accelerate the promotion of green production and cleaner production. New wall material manufacturers must promote cleaner production, reduce air pollutant emissions, sewage emissions, and noise emissions, and strengthen comprehensive utilization; accelerate the pace of technological transformation, improve production processes, product grades and products Quality level; improve enterprise management, improve quality, environment, safety and other control guarantee systems, as soon as possible to meet the "green product evaluation-wall materials" (GB/T35605) standard requirements. Third, it is necessary to speed up the promotion and application of green wall materials, conscientiously implement the relevant national and provincial policies on the development of new wall materials and green building materials, strictly implement the regulations of Jiangsu Province on the development of new wall materials and the regulations of Jiangsu Province on the development of green buildings, and speed up the promotion and application of green wall materials. New wall material products should be used in construction projects, and green wall material products should be used in construction projects invested by the government.
The release of the new "Product Catalog" and "Industry Orientation" will implement the Provincial Party Committee and Provincial Government's "Jiangsu Province Quality Improvement Action Implementation Plan" and the "New Wall Material Promotion and Application Action Plan" by the General Office of the National Development and Reform Commission and the General Office of the Ministry of Industry and Information Technology. Actively develop waste and green new wall materials, support green buildings and prefabricated buildings, and promote the high-quality development of the wall material industry will play a positive role.
