Lanxi textile printing and dyeing industry cleaner production audit innovation pilot became the first batch of national evaluation projects
"By including the clean production audit and innovation pilot of the textile printing and dyeing industry in Lanxi City, relevant leaders and experts of the Lanxi Branch of the Jinhua City Ecological Environment Bureau conducted pulse diagnosis and guidance on the company, which inspired us very much." The person in charge of Lanxi Yahua Textile Printing and Dyeing Co., Ltd. said that the company, in conjunction with Lanxi Xinao Gas, invested 4 million yuan to install a photovoltaic energy storage system. The project adopts the "photovoltaic power generation + energy storage" model to store electrical energy when electricity is low and during electricity consumption. Release electricity at peak times, saving an annual price difference of about 2.35 million yuan.
Recently, the General Office of the Ministry of Ecology and Environment and the General Office of the National Development and Reform Commission jointly announced the list of the first batch of cleaner production audit and innovation pilot projects that passed the evaluation. 44 cleaner production audit and innovation pilot projects across the country passed the evaluation."Lanxi City Textile Printing and Dyeing Industry Clean Production Audit and Innovation Pilot Project" was successfully selected, becoming the first batch of cleaner production audit and innovation pilot projects in the country that passed the evaluation.
The textile industry is an important pillar industry in Lanxi City. In December 2022, the cleaner production audit and innovation pilot project of Lanxi textile and dyeing industry was included in the first batch of cleaner production audit and innovation pilot projects in the country.
"The core of this pilot is the innovation of cleaner production audit models. We have changed the past audit model for a single printing and dyeing enterprise, organized the enterprise in a unified manner, and created a new audit model that is systematic, large-scale and rapid, reduce audit costs and reduce the burden on enterprises." Wu Shengzhong, Party Secretary and Director of Lanxi Branch of Jinhua City Ecological Environment Bureau, introduced.
Based on the actual situation of the industry, Lanxi has formulated the "Overall Evaluation Index System for Clean Production in the Textile and Dyeing Industry in Lanxi City"(Trial Implementation) to classify and clarify the cleaner production evaluation indicators, weights and benchmark values of four types of production enterprises, including woven dyeing and finishing fabrics, knitted dyeing, printed fabrics, and yarn dyeing. Based on the original clean production evaluation indicator system for the textile printing and dyeing industry issued by the country, 16 indicators such as renewable energy use per unit of product and carbon emissions per unit of product have been added and adjusted to promote the indicator system to be more leading and intuitive. and advanced.
It is understood that for the 20 companies included in the pilot this time, Lanxi City diagnoses the production process throughout the process based on the product categories of textile printing and dyeing enterprises, sorted out 16 key common lists in the industry, and issued a "one enterprise, one policy" problem rectification list and a list of positive recommended practices for each enterprise. Based on the review and evaluation results, optimize and adjust the "Overall Evaluation Index System for Cleaner Production in the Textile and Printing Industry of Lanxi City."
In addition, Lanxi City also takes the opportunity of Zhejiang Province to create the country's first collaborative innovation zone for pollution reduction and carbon reduction to build a set of pollution reduction and carbon reduction index evaluation system for clean production in the textile printing and dyeing industry. The first-level indicators cover 4 items such as energy resource utilization level, pollutant emission level, carbon emission level, and enterprise low-carbon management level. The second-level indicators cover the proportion of renewable energy use, the proportion of small-bath ratio dyeing machines, industrial water reuse rate, comprehensive utilization rate of general industrial solid waste, Wastewater emissions per unit of industrial added value, chemical oxygen demand emissions per unit of industrial added value, allocation rate of flue gas treatment facilities of shaping machines, carbon emissions per unit of industrial added value, whether they are included in green factories at the municipal level and above, whether there is a digital management platform, 11 items including whether major emergencies have occurred in the past three years, are subject to dynamic management.
Through this pilot, the overall level of cleaner production in the textile printing and dyeing industry in Lanxi City has been greatly improved, the synergistic effect of pollution reduction and carbon reduction has been significantly enhanced, effectively improving the industry's "green content". According to statistics, the carbon emissions per unit of industrial added value, energy consumption per unit of industrial added value, chemical oxygen demand emissions per unit of industrial added value, and ammonia nitrogen emissions per unit of industrial added value of the 20 enterprises included in the pilot dropped by 29.1%, 24.7%, 21.7%, and 19.2%, respectively, compared with 2021.
