modernization The development of technical printing has made modern life more colorful, but it has also followed the “three wastes†caused by the use of chemicals and energy in the printing production process, including the social environment and the use of its final products in the process of use and disposal. The impact of human health. With the continuous improvement of the public's awareness of environmental protection, green printing has caused widespread concern in society, coupled with domestic and international environmental protection needs, industrial sustainable development needs and the needs of self-development of enterprises, which have prompted more and more enterprises to be green. Printed on the agenda. In this context, Chongqing Yuanda Printing Co., Ltd. did not wait and see, hesitated, but to fulfill its social responsibility as its purpose, to protect the ecological environment as its own responsibility, and began to actively promote green environmental protection work. Since the launch of the green printing work, Yuanda Printing has responded positively and adopted a series of measures.
1. Improve environmental protection measures
In terms of sewage treatment, Yuanda Printing has set up a special person to operate and manage the sewage treatment facilities, and upgrade the facilities. The upgraded sewage treatment capacity of the facilities has been upgraded from 20 tons/day to 60 tons/day, and through precipitation, Isolation, biochemical and materialized treatment ensure that the treated sewage meets national emission standards. Yuanda Printing also modified the rain/sewage drainage network: through the investigation of underground rain/sewage drainage network, repairing old pipelines, improving rain/sewage diversion, standardizing rain/sewage well identification and flow direction marking, and eliminating rain/sewage mixing Row phenomenon. Yuanda Printing also regulates the production of exhaust gas discharge devices, installs exhaust pipes according to the classification of exhaust pollutants, adds activated carbon adsorption devices, and raises the exhaust pipes to 15 meters to ensure that the production waste gas is not scattered; In terms of storage management of the object, Yuanda Printing has done a good job of classifying and storing solid waste according to the nature of the hazard, adding facilities such as “anti-leak, anti-diffusion, anti-leakageâ€, posting waste signs and safety warning signs, and establishing dangerous solid waste. The material management account ensures the legal transfer of hazardous solid waste.
In addition, Yuanda Printing also eliminated outdated production equipment and processing technology, and replaced the backward equipment with a fully automatic rotary printing machine, which not only improved production efficiency, reduced energy consumption, but also reduced exhaust gas and noise during production. And the generation of hazardous waste.
2. Carry out "clean production audit"
Through the analysis of production status, energy consumption for production, various pollutant discharge links and clean production potential, the goal of cleaner production is clarified. In turn, we will continue to promote cleaner production, increase investment, and do a good job in energy conservation, pollution reduction, and efficiency improvement.
3. Introduce advanced process equipment
Yuanda Printing replaced the traditional PS plate making process with advanced CTP plate making technology, which reduced environmental pollution during the plate making process, improved production efficiency and product quality. With automatic nine-color rotary press, printing, matching and backing were realized. Black cover molding, improved production efficiency; purchased Heidelberg SM-74, Heidelberg SM-102, Roland 706+1, Roland two-color machine, Palace waist 4-color machine, Palace waist 4+1 and other international brand printing equipment , improved Printing capacity, reducing energy consumption, reducing environmental pollution caused by the production process; adding ink recycling equipment, focusing on the production of residual ink, setting up a special area for storage in the warehouse, dedicated to the printing production of monochrome products, improving resources Utilization efficiency; a developer purifying device is configured to reduce pollutant emissions by purifying the developing wastewater and the stencil.
4. Use FSC certified paper
Yuanda Printing chose to use the paper supplier of “FSC Forest Certification†as a partner to ensure that the raw materials of the products are all from well-managed forests.
5. Adopt environmentally friendly printing materials
Yuanda Printing actively uses environmentally-friendly printing materials such as water-based inks, soy inks, water-based varnishes, water-based car wash water, alcohol-free fountain solutions, and plant dusting, and confirms the environmental protection of printed materials by confirming third-party testing reports.
6. Establish energy management control
Yuanda Printing has established a series of energy management controls. For example, the “Ink Recycling Management System†has clearly defined the recycling of printing inks; the “Local Lighting Control System†regulates the management of energy-consuming equipment; the “Waste Management System†regulates the rational use and management of production waste.
The 100% Biodegradable Trash Bags make it easy to sort and recycle kitchen waste!
Our Biodegradable Compostable Garbage Bags can be burned together with kitchen waste, and no harmful carcinogens such as dioxins are produced.We recommend that you compost compostable trash bags together with kitchen waste, bury them in the soil or compost in a microbiological environment for 3 months. Our biodegradable compostable garbage bags will be 100% completely degraded into Carbon dioxide and water become organic fertilizers.
