Hangzhou releases plan: key industries to promote water-based products and restrict the production of coatings, inks, adhesives, and solvent-based products

Recently, the General Office of the Hangzhou Municipal People’s Government has issued the “Hangzhou Atmospheric Environmental Quality Plan for Reaching Standards within a Deadline”. The overall planning scope is Hangzhou City, with a total planned area of ​​16,596 square kilometers. By 2020, complete the construction of the framework of the local standard system for the “clean emission zone”, and by 2025, achieve the city’s goal of building a “clean emission zone” for the atmosphere.

Planning range
The overall planning scope is Hangzhou City, with a total planned area of ​​16,596 square kilometers.
Planning period
The planning base year is 2015. The planning period is divided into short-term (2016-2020), medium-term (2021-2025) and long-term (2026-2035). To
Target point
The target point is the city’s state-controlled monitoring station (not including the background station), and the points in Hangzhou Dajiangdong Industrial Cluster, Fuyang District, Lin’an District, Tonglu County, Chun’an County, and Jiande City are also considered. To
Key projects
Mainly include energy structure adjustment, clean emission transformation of coal-fired boilers, thermal power, and cement industries, VOCs pollution control in key areas and key industries, industrial structure adjustment, automatic monitoring network construction and other engineering projects. To
The plan also proposes to implement special rectification of VOCs and strengthen the treatment of odors and odors. The relevant contents of the coating, ink, and adhesive industries are as follows:
1. Promote the emission reduction of VOCs in key regions and key industries.
Strictly implement the “Zhejiang Province Volatile Organic Compounds Deepening Governance and Emission Reduction Work Plan (2017-2020)”. Focus on promoting the chemical, industrial coating, printing and dyeing and chemical fiber industries in Xiaoshan District, the chemical industry, industrial coating, packaging and printing in Fuyang District, the industrial coating, printing, printing and dyeing industry in Yuhang District, the industrial coating and printing in Lin’an District, and the chemical industry and industry in Tonglu County. Coating industry, Hangzhou Economic Development Zone, chemical industry, industrial coating, packaging and printing, rubber and plastic products, chemical fiber industry, Hangzhou Dajiangdong Industrial Cluster Area, chemical industry, industrial coating, printing and dyeing, chemical fiber industry, Jiande City chemical industry, synthetic leather industry Deepen the governance of VOCs. By 2020, the city’s total VOCs emissions will drop by more than 26% compared with 2015. Among them, the chemical, chemical fiber, industrial coating, textile printing and dyeing, rubber and plastic product industries decreased by more than 30%, and the packaging and printing industry decreased by more than 50%. Continue to promote the chemical fiber spinning, craft shoes, bathroom, architectural decorative film industries in Xiaoshan District, the cosmetics, badminton racket, and plastic products industries in Fuyang District, the decorative paper and printed circuit board industries in Lin’an District, the Tonglu pen industry, the plywood industry in Jiande City, etc. Governance of VOCs in agglomeration industries. By 2025 and 2035, the city’s industrial source VOCs emissions will be reduced by 50% and 70% respectively compared with 2015.
Accelerate the elimination of outdated technology and equipment. Eliminate water flushing pumps (except for special processes), open-end centrifuges, open-flow filter presses and non-closed suction filtration equipment, electric heating blast drying, old-fashioned hot air circulation drying and other drying equipment. Eliminate the manual packaging (filling) process and equipment for pesticide products. Eliminate traditional ink production equipment with an annual capacity of less than 300 tons, ban the production of benzene-based solvent-based inks, and eliminate all production equipment for coatings, adhesives and inks that do not have VOCs collection, recycling/purification facilities. Eliminate other processes and products that are seriously polluting by VOCs, and carry out VOCs reduction and control that are not economically feasible.
2. Promote the substitution of environmentally friendly raw and auxiliary materials.
Promote the use of environmentally friendly raw and auxiliary materials with low (no) VOCs content and low reactivity, and limit the use of coatings with a VOCs content of >420 g/L in the ready-to-use state. By 2020, the replacement ratio of low-volatility coatings such as water-based and UV-curable coatings in the wood furniture manufacturing industry will reach more than 60%, and the replacement ratio of water-based adhesives will reach 100%. Construction machinery manufacturing industry and steel structure manufacturing industry use high solids, powder coatings to use more than 50%. In the automobile manufacturing industry, the proportion of primer and intermediate coating water-based paint in the vehicle manufacturing industry reaches 100%. In the packaging and printing industry, the replacement ratio of environmentally friendly raw and auxiliary materials with low VOCs content is not less than 60%, and inks with single-component solvents are preferentially used for irreplaceable inks. The rubber industry promotes the use of new coupling agents, adhesives and other products, and promotes the use of paraffin oil to fully replace ordinary aromatic oil, coal tar and other additives.
3. Develop clean, green and environmentally friendly products.
Promote the use of green products with low (no) VOCs content. The pesticide industry promotes the use of water-based preparations, and the proportion of green pesticide preparations used has reached more than 70%. The coating, ink and adhesive manufacturing industry restricts the production of solvent-based products, promotes water-based, solid, and UV-curable coatings, promotes water-based, plant-based, and UV-curable inks, and promotes water-based, hot-melt, and solvent-free inks Types of adhesives, coatings, inks, and adhesives with low (no) VOCs content have reached 60%, 70%, and 85%, respectively. The proportion of low (no) VOCs tire products of tire manufacturers in the rubber industry has reached more than 40%.
