Q & A On Policy Interpretation Of "Guidance On Green Access Of Textile Printing And Dyeing (Digital Jet Printing) In Zhejiang Province (Trial Implementation)"

Q: what is the background of the guidance?

A: since 2020, in the process of "three services" activities, some textile printing and dyeing enterprises have proposed that the technical level of textile printing and dyeing industry is constantly improving. Compared with the traditional roller printing, flat screen printing and rotary screen printing, the pollutant emission of textile printing and dyeing is greatly reduced, The level of green production has been greatly improved. It is suggested that the relevant competent departments should issue corresponding supporting measures to support the environmental zoning control of "three lines and one single" for green manufacturing process.

In order to speed up the development and industrial application of digital ink jet printing technology in textile printing and dyeing industry of our province, encourage the use of technology and equipment with high technology content, low pollution emission and low energy consumption, promote industrial transformation and upgrading, and improve the green development level of textile printing and dyeing industry in our province, the provincial ecological environment department and the provincial economic and information department jointly conducted a series of measures to promote the development of digital ink-jet printing technology in textile printing and dyeing industry in our province, Combined with the needs of enterprises, relevant research work was carried out to study the relevant policy support measures for the digital jet printing technology and equipment (including related finishing process before and after) with high technology content, low pollution emission and low energy consumption in textile printing and dyeing industry.

Q: what work has been done to formulate and promulgate the guiding opinions?

A: the Provincial Department of ecological environment, together with the Provincial Department of economy and information technology, strengthened the joint efforts of the departments, and organized experts from the Provincial Academy of Environmental Sciences, Zhejiang University of science and technology, and the provincial printing and dyeing industry association to carry out analogical research, discussion and exchange, and special consultation. According to the requirements of the procedure for the preparation and issuance of administrative normative documents, letters were sent to solicit opinions from relevant provincial departments, local ecological and environmental protection departments, industry associations and some representative enterprises, and public opinions were solicited from the portal website of the Provincial Department of ecological environment. After fully listening to the suggestions of all parties, the green access guidance was printed and issued on March 24.

What is the specific scope of application of the guidance?

A: the guidance is applicable to the newly-built, expanded, technologically modified or relocated digital jet printing projects in the textile printing and dyeing industry in Zhejiang Province. The project construction content meets the requirements of production process and index system, which belongs to the green access project.

Q: what requirements should be met in order to give specific support policies?

Answer: for the textile digital ink jet printing project with the content meeting the requirements of production process and index system, corresponding policy support measures will be given.

(1) green access production process: including digital direct ink-jet printing process and digital transfer ink-jet printing process, excluding other printing processes such as roller printing, flat screen printing and rotary screen printing; It can include less pollution in the front and back production process, excluding cooking, scouring, bleaching, mercerizing, alkali reduction and other pollution emission of the pretreatment process and dyeing process.

(2) green access assessment indicators: including fresh water intake, energy consumption, drainage, VOCs and dyeing and finishing lampblack emissions per unit product, which shall meet the requirements of relevant index limits. Following the principles of promoting emission reduction, reducing energy consumption, encouraging advancement and promoting innovation, in order to reflect the green access requirements, the fresh water intake is controlled by 40% of the relevant limit requirements of the "printing and dyeing industry specification conditions (2017 Edition)" and the energy consumption is controlled by 60% of the relevant limit requirements of the "printing and dyeing industry specification conditions (2017 Edition)", The water discharge per unit product shall be controlled according to 30% of the relevant limit value requirements in Table 3 of "emission standard of water pollutants for textile dyeing and finishing industry" (GB 4287-2012), and the emission of VOCs and oil fume from dyeing and finishing industry shall be controlled according to 50% of the relevant limit requirements in Table 1 of emission standard of air pollutants for textile dyeing and finishing industry (DB 33 / 962-2015).

Q: what are the specific supporting policies for projects that meet the requirements?

A: there are three aspects of policy support: first, the "three lines and one single" ecological environment zoning control requirements and the industrial project classification of the industrial park where the project is located can be degraded management; Second, the allocation support of emission right indicators of major pollutants; Third, it is included in the green transformation support direction of manufacturing industry.
