3 Green Manufacturing Mode
The green manufacturing model refers to the modern manufacturing model that comprehensively considers the environmental impact and resource efficiency under the premise of guaranteeing the function, quality, and cost of the product. It allows the product to be used from design to manufacture to be scrapped. No environmental pollution occurs throughout the product life cycle. Or minimize environmental pollution, meet environmental protection requirements, have no harm to the ecological environment or minimal harm, save resources and energy, maximize resource utilization, and minimize energy consumption
3,1 Clean Production
Cleaner production is recognized as an important environmental protection strategy for the coordinated development of the environment and economy, and it is a key means for achieving sustainable development.
The connotation of clean production is to apply the idea of ​​protecting the environment and comprehensively preventing pollution to the production process and products, and integrate them into the various stages of the product life cycle; for the production process, clean production includes saving raw materials and energy, and eliminating toxic substances. Raw materials and reduce their quantity and toxicity before all emissions and wastes leave the production process. For products, "Cleaner production aims to reduce the entire life cycle of products (from the extraction of raw materials to the final disposal after use of products) to humans. And the adverse effects of the environment. It should be pointed out that "clean production is not only to emphasize environmental protection. It also emphasizes that the optimal use of resources and energy "maximizing the use of resources and energy and minimizing the generation of waste" is the fundamental measure for a global environmental cure. Clean production is the production of green products through the "ISO14000 certification" to increase market competitiveness. Powerful weapon. The following steps are recommended for the implementation of cleaner production for packaging companies.
(1) Renew the concept, step by step from the company's leadership to every employee to update their concepts, and establish a new awareness of environmental protection, especially - the product life cycle. And - mainly prevention, governance supplemented - the comprehensive prevention. Awareness must recognize that fundamentally solving environmental problems "must transform the previous resource-based development model into a technology-based development model," which means relying on scientific and technological progress, saving resources and energy, "improving efficiency," reducing waste emissions, and implementing cleaner production and "Civilization consumption" establishes a new model of development coordinated by economy, society, resources, and the environment. To implement the clean technology, we must proceed from the actual situation. At present, we must implement waste-free and zero pollution immediately. The process is still very difficult. We can implement unified planning and step-by-step implementation.
(2) Conscientiously analyze the production-greenness of the company
According to the product life cycle theory, we analyze the various stages of the product life cycle, including each process, analyze the resources and energy consumption in production, the environmental pollution and the damage to the human body, and identify the “green†weaknesses in the production process. In order to focus on breakthroughs
(3) Formulate an enterprise clean production project implementation plan The enterprise clean production project implementation plan must be formulated for specific products. Newly-developed products and old products "The cleaner production program should implement two different routes. For newly-developed products, we must strictly follow the clean production requirements, adopt the green concurrent design method, collect raw materials, save energy, and save materials. The production technology/circulation sales, waste recycling, recycling processing and other aspects adopt advanced green technologies to make them green products. For old products, the focus is on the pollution status of each link, the consumption of energy resources, and the labor protection situation of personnel. Its manufacturing process system is undergoing green transformation to achieve clean production.
The implementation of clean production projects by enterprises shall be carried out in conjunction with the implementation of the International Environmental Standards Series ISO 14000. "Because there are many jobs in the two industries that are identical, the goal is to raise funds in a consistent manner, and to organize the implementation of cleaner production requires more investment. In addition to raising loans, the “rolling investment method†is recommended, which means that part of the proceeds obtained after the implementation of a plan is used as the start-up fund for the implementation of the latter plan. This method can reduce the impact on the company’s fund plan.
When implementing the project plan, it is necessary to focus on the selection and installation of civil construction equipment, trial production, and project acceptance and evaluation.
(5) Follow-up analysis, review and evaluation of project implementation effectiveness Tracking the entire process of clean production from technical, environmental, economic, and social benefits to all parties. After obtaining a large amount of data for statistical analysis, the Chemical production project implementation plan for scientific assessment, and provide decision-making departments with useful information and decision-making basis
3,2 Environment-Oriented CIMS Technology
The most important feature of CIMS is its integration. It integrates technical, economic, and management computer-assisted technologies and various aspects of information from various stages of the product life cycle, so that it can take measures in all aspects to make the entire manufacturing process. The system can operate in the best condition to achieve overall optimization and obtain the best economic benefits. The environment-oriented CIMS technology "beyond the advantages of CIMS" is also due to the adoption of green measures such as concurrent design/clean production at various stages of the product life cycle, so that the environment-oriented CIMS technology has the characteristics of CIMS in addition to green The characteristics, so that the system can produce green products with the best economic benefits.It is also emphasized that the environment-oriented CIMS is not a closed manufacturing system, but a dynamic open system, which constantly exchanges with the outside world Information, constantly adjusting and improving itself based on external information and needs, producing green products that best meet the needs of the external market
Environmental-oriented CIMS technology is very suitable for the needs of China's packaging industry "should be actively promoted in China's packaging industry" The reasons are as follows, packaging is different with the product type / specification / replacement. In the market economy, packaging also needs to change with the level of market demand, decoration, and materials. Therefore, the production of packaged products is mostly small-batch, multi-variety types of production. CIMS is a system with good flexibility and flexibility. When the product is changed, it is easy to adjust "Low adjustment cost (close to zero) can reduce the production cost of packaging products that often change. China's packaging companies are mostly small and medium-sized enterprises," the degree of modernization is poor, the introduction of CIMS technology can greatly improve the design and processing of enterprise products. The degree of modernization in manufacturing, business management, information collection, enterprise decision-making, and production, sales, and recycling processes can greatly increase the economic efficiency of enterprises and improve the quality of enterprise managers and technicians. The status quo of packaging enterprises in China is still small and decentralized, and most of them have not formed scale. Therefore, economies of scale cannot be formed in product production or equipment use. The use of CIMS technology enables these packaging companies to be associated or grouped to increase production scale and economic scale. Improve the utilization of some important key equipment or idle equipment "to get the scale benefits of production.
