1. Control of toxic and hazardous substances The continuous innovation of production technology in the Lighting electrical industry has played a good role in promoting the use of toxic and hazardous substances in the production process. Many companies have taken active measures to reduce the use of harmful substances such as mercury and lead from various aspects such as production processes, equipment and raw materials. For example, using amalgam such as amalgam or mercury to replace liquid mercury, reducing or precisely controlling the amount of mercury injected; developing low-mercury-consuming phosphors, increasing coating film, increasing helium pressure, etc., reducing the consumption of mercury in lamps; improving glass formulations, Production of lead-free glass similar to leaded glass; improved solder formulation, use of lead-free solder, etc.
The emerging new lighting technology has also opened up new avenues for reducing the use of toxic and hazardous substances in lighting appliances. For example, mercury-free metal halide lamps are a hot spot currently being developed, using zinc or other metal substitutes instead of mercury to excite phosphors to produce light. Non-traditional light source products such as microwave sulfur lamps, semiconductor light sources, and solar lighting technologies are also constantly breaking through the bottleneck of technology and gradually entering the general lighting market, becoming a new generation of lighting products with broad development prospects.
2. Waste product recycling For the pollution caused by waste products and recycling problems, the company and the industry management department have done a lot of work.
First, continuously improve the quality and longevity of the product. The improvement of product quality and longevity have played a positive role in reducing waste products. At present, the national standard stipulates that the average life expectancy of single-ended fluorescent lamps and self-ballasted fluorescent lamps has been increased to 5,000 hours, and many companies are still committed to continue to improve the service life of the products and the research on the performance of various aspects. The increase in product life has greatly reduced the speed of product elimination, and to some extent reduced the amount of used products.
Secondly, the recycling of used lighting products is also increasingly valued by enterprises and relevant departments. At present, a small number of joint ventures and some leading enterprises in China have begun to deal with the recycling and disposal of used lamps, and have the ability to effectively separate and classify and recycle phosphors and glass tubes. The relevant domestic departments have conducted special research on the research and development and manufacture of waste lamp recycling equipment, and have achieved preliminary results.
Relevant national departments have also formulated relevant standards and policies, which have given certain support to the development of circular economy in the lighting and electrical industry:
â— In the Medium and Long-Term Plan for Energy Conservation Promulgated by the National Development and Reform Commission, the “development and application of mercury recovery treatment technology for mercury-containing wastes and the manufacture of complete sets of equipmentâ€, “rare and rare earth metal deep processing and its application†are listed as encouraged products or Technical projects; "Tungsten, molybdenum, tin, antimony and rare earth mining, smelting projects and bismuth oxide, lead-tin solder production projects (except for renovation projects)" General shearing machine, bending machine, pipe bending machine manufacturing project is listed as Restricted categories; "Tungsten, tin, antimony, ionic rare earth smelting projects and tungsten processing (including hard alloys) projects not approved by the competent department of the State Council are listed as eliminated. Waste lighting product processing equipment has also been included in the newly revised Catalogue of Environmentally Friendly Industrial Equipment (Products) that is currently encouraged by the state.
â— The State Environmental Protection Administration issued the "Technical Requirements for Energy-saving Lamps and Tube-type Fluorescent Lamp Environmental Labeling Products"; and carried out environmental labeling product certification for the two products. Based on the performance and safety certification of the products, further proposed in production, use and It meets environmental protection requirements during the treatment process, and has environmental advantages such as low toxicity, less harm, and resource conservation compared with similar products. The company's quality control, environmental protection measures, etc. have been evaluated and investigated as a whole.
â— The Ministry of Information Industry has formulated (Electronic Information Products Pollutant Control Management Measures), which involves high-pressure sodium lamps, energy-saving lamps, fluorescent lamps, automotive lamps, holiday lamps and other electric light source products and lighting components related to the lighting industry.
â—The Lighting Electrics Standards Committee also plans to complete the formulation of the “Recycling Specifications for Waste Lighting Equipment†and the “Specifications for the Limitation of Toxic and Hazardous Substances in Lighting Electrical Products†in 2007.
â— In the "Eleventh Five-Year Plan" of the National Environmental Protection Standards, it is proposed to revise the "Gas Discharge Lamp Processing Industry Pollutant Emission Standard" and "Disposal Gas Discharge Lamp Recycling Pollution Control Technical Specification". It will also revise more than 10 relevant standards such as “Residual Non-ferrous Metal Storage, Dismantling, Transportation Environmental Pollution Control Standards†and “Electronic Waste Treatment and Disposal Engineering Technical Specificationsâ€.
At present, the development of circular economy in the lighting and electrical industry has just started. It is also necessary to further improve policies and standards through joint efforts of all parties; improve the capabilities of technology and equipment manufacturing, and promote the healthy development of circular economy in the lighting industry.
