The environment is undoubtedly one of the many grave challenges facing mankind. How to properly handle the balance between human development and resource consumption and environmental protection is a major issue that humankind will face in the future. As early as 1987, the World Commission on Environment and Development explained the concept of sustainable development for the first time in the report “Our Common Future†and it was recognized by all countries in the world. China attaches great importance to sustainable development and the scientific development concept is a people-oriented, comprehensive, coordinated and sustainable development concept. The concept of sustainable development means coordinating the harmonious development of man and nature, handling the relationship between economic development, population growth and resource utilization, and ecological environment protection, and promoting the development of the entire society, a prosperous living environment, and a sound ecological development path. All walks of life in the country have been conscientiously studying and implementing them in depth, and the packaging industry is no exception.
The adverse impact of the packaging industry on the environment and the consumption of large amounts of natural resources have always been the focus of attention. The packaging industry is still dominated by small and medium-sized enterprises. The industry standards are still not perfect, and the binding of enterprises is not enough, especially in recycling of packaging and packaging waste. In order to deeply implement the scientific concept of development, achieve sustainable development, reduce the negative impact of packaging waste on the ecological environment, and constrain packaging production companies, the “national standards for packaging and packaging waste†will be introduced. This standard includes seven parts: treatment and use of general principles, assessment methods and procedures, pre-reduction of dosage, reuse, material recycling, energy recycling, biodegradation and composting. The starting point for manufacturers to consider whether or not to implement the relevant standards is different from that of standard setting units. The company first considers maximizing profit and ensuring product quality. If this is contrary to this, it will be difficult to promote it in the future, and most of the packaging companies will be small and medium-sized. Enterprises have more difficulties in supervision. Only when they are found in the implementation process, the company has found that this standard not only contributes positively to energy conservation, consumption reduction, ecological environment, and recycling economy, but also enables manufacturers to discover this on their own. The benefits of standards.
In the standard formulation process, a number of companies were selected as key research companies.
In the process of implementing this standard, the selected carton factory, on the premise of ensuring the quality of the carton, aims to reduce the use of resources by reducing the amount of paper used. The company scientifically defines the critical range of packaging reductions. The company adopts a test recording method to repeatedly test and record the number of damages in various corrugated cartonboard tests, thereby scientifically determining the critical range of corrugated board weight reduction.
After continuous efforts, with the continuous improvement of the material of the kraft paper, the company took the initiative to reduce the carton kraft paper from 300 grams to 280 grams, to 250 grams and 200 grams, and now it is basically 200 grams or less. 110 grams of paper. Relevant person in charge of the carton factory calculated an account. Now all the box-making paper is reduced by 20%. According to the whole plant, 20 million square meters of paperboard is produced all year round. The original paper is 20,000 tons, and it is now reduced to 16,000 tons. Paper, saving 4,000 tons of paper, and completely saved is the use of wood pulp production of kraft paper. By reducing the weight, a layer of paper can save a cost of 5 cents, and a carton can save 2 yuan. This has increased the competitiveness of enterprises and increased profit margins, while users have also reduced packaging costs. More than 80% of the cartons produced by the company are now printed with recycling marks, and customers are encouraged to use cartons with recycling marks.
The selected color printing plant is a professional manufacturer of packaging products such as color printing, pulp molding, cartons and blister packs. Enterprises need to use 100 tons of waste paper every month to build pulp production molding packaging products. About 30 tons of leftovers for the production of prints and color boxes are recycled to create pulp, and non-conforming products during the production of molded products are returned to the beating pool at any time.
According to the standards for recycling and recycling, enterprises strictly classify the recycling of waste paper and color box production scraps. For example, there is a separation between printing ink and non-printing ink, and clean leftover material is separated from recycled waste paper to produce different modules. Plastic products, put different waste paper raw materials. When the raw materials are put in, according to the materials stipulated in the standard, the recycled materials are regenerated into a product that meets the requirements at a reasonably determined weight percentage during the manufacturing process. Due to the different materials needed for new packaging, the percentage of raw materials can be changed. In accordance with this provision, the company operates raw material ratios for various types of pulp molded packaging products to achieve satisfactory results and ensure the quality of molded products.
The company believes that the material recycling standards are very feasible in the production and operation, and can improve the quality of recycled materials. Recycling materials not only saves resources, protects the environment, but also increases corporate profits. According to the use of 100 tons of waste paper per month, 30 tons of the company's production of prints, color box leftovers into the recycling, each year for the company to increase efficiency 300,000 yuan.
Through the trial implementation of the “packaging and packaging waste†standard, companies that have focused on research and development have benefited from it, which has reduced costs, increased profit margins, increased corporate benefits, promoted technological innovation and development of enterprises, and achieved Its use reduces environmental pollution, saves resources, and is conducive to sustainable development.
