How can brass lock cylinder manufacturers achieve sustainable production by optimizing the use and recycling of raw materials?

1. Raw material composition and resource characteristics of brass lock cylinders
The main raw materials of brass lock cylinders are copper, zinc and a small amount of other alloy elements. Copper, as a metal with high recycling value, has relatively low resource tension and good conductivity, corrosion resistance and processability, which makes brass lock cylinders widely used worldwide. Zinc, on the other hand, is mainly used to improve the hardness and strength of brass. Therefore, the efficiency of copper and zinc use directly determines the environmental impact of brass lock cylinder production.

Although copper and zinc resources are relatively abundant, their mining and processing processes consume a lot of energy and produce certain pollution. Especially in the mining and refining process, a large amount of carbon dioxide emissions and damage to the ecological environment may be caused. Therefore, by optimizing the use of these raw materials, reducing waste and implementing recycling, it can not only improve production efficiency and reduce costs, but also effectively reduce the impact on the environment and promote the sustainable development of brass lock cylinder production.

2. Optimize the use of raw materials: reduce waste and improve utilization
The first step to optimize the use of raw materials is to accurately control the procurement and consumption of materials. Through modern production management systems, manufacturers can accurately calculate and monitor the raw materials such as copper and zinc used in the production process of brass lock cylinders. This refined management can ensure that each unit of raw materials can be converted into finished products to the greatest extent possible, avoiding excessive waste.

a. Efficient cutting and processing technology
In traditional brass lock cylinder production, the cutting and processing process may generate a large amount of waste. In order to reduce waste, many manufacturers have adopted more efficient cutting and processing technologies, such as laser cutting and precision milling. These technologies can not only improve processing accuracy, but also reduce scraps and metal debris generated during the cutting process. Through precise CNC processing, the parts of the lock cylinder can achieve maximum raw material utilization in one-time processing, reducing the generation of waste.

b. Intelligent production management system
With the development of information technology, intelligent production management systems (such as ERP, MES, etc.) are increasingly widely used in the production of brass lock cylinders. These systems help manufacturers accurately grasp the raw material consumption of each link by real-time monitoring and scheduling of the production process. For example, by using big data analysis and artificial intelligence technology, it is possible to predict the demand for raw materials in each batch of production and automatically adjust production parameters, thereby effectively avoiding excessive procurement or waste of raw materials.

3. Recycling: Recycling and Reuse of Copper and Zinc
The recycling and reuse of copper and zinc is a key link in achieving sustainable production of brass lock cylinders. Recycling copper and zinc can not only reduce dependence on natural resources, but also greatly reduce carbon emissions in the production process. Copper has a long history of recycling, with almost no loss of its physical and chemical properties, and the benefits of reuse are significant.

a. Process of Recycling Copper and Zinc
Brass lock cylinder manufacturers usually recycle copper and zinc in two ways: one is through waste recycling, that is, remelting and processing metals such as scraps and scraps in the production process into new brass materials; the other is through recycling old products, extracting copper and zinc from scrapped lock cylinders, old door locks and other items. Both methods can effectively reduce the demand for raw materials, save costs, and reduce the environmental impact of production.

During the waste recycling process, manufacturers will establish a special metal recycling and sorting system to classify and process different types of metals to ensure that each metal can be recycled. For copper and zinc recovered from old products, manufacturers usually use professional refining processes to increase their purity to reusable standards. These recycled copper and zinc can be re-added to the production process after melting, replacing some newly purchased raw materials, thereby reducing dependence on new resources.

b. Economic and environmental benefits of recycled copper
According to research data, recycled copper can reduce energy consumption by up to 85% and reduce carbon dioxide emissions by more than 75% compared to the production of new copper. Recycling copper can not only reduce production costs, but also effectively reduce the burden of waste on the environment. Therefore, more and more brass lock cylinder manufacturers are actively promoting the recycling and reuse of copper to achieve both economic and environmental benefits.

4. Treatment and reuse of production waste
In addition to the recycling of copper and zinc, other waste generated during the manufacturing process of brass lock cylinders (such as metal debris, waste liquid, waste gas, etc. generated by cutting) also need to be properly handled. Modern manufacturers usually use the following methods to manage and reuse waste:

a. Treatment and utilization of waste gas
During the casting and heating process of brass, a certain amount of waste gas may be generated, especially gas containing harmful substances. To reduce air pollution, manufacturers use waste gas treatment equipment, such as catalytic combustion furnaces, activated carbon adsorption and other technologies to purify waste gas. At the same time, some of the treated waste gas can be collected and used in other production links in the factory as an alternative source of energy.

b. Recycling of waste water
Cooling and cleaning in the production of brass lock cylinders usually use a lot of water resources. Manufacturers can treat and purify the waste water generated in the production process and reuse it by establishing a wastewater recycling system, reducing water consumption and avoiding water pollution.

5. Promote green procurement and cooperation
In addition to optimizing their own production process, brass lock cylinder manufacturers can also promote sustainable production through green procurement policies. This means choosing raw material suppliers with environmental certification to ensure that the purchased materials such as copper and zinc meet the requirements of sustainable development. For example, choose suppliers that use environmentally friendly mining and smelting technologies to further reduce the ecological footprint of raw materials.
