1. Cut in from the source and nip in the bud. Enterprises can improve the utilization rate of raw materials and energy in the production process by improving technology, save raw materials and energy, and thus reduce waste; In addition, enterprises can also develop new materials to replace the original materials. New materials should have a longer service life and better performance, and less waste should be generated during the acquisition and treatment of new materials; The new materials used should be non-toxic and harmless, toxic and harmful raw materials should be eliminated, and the emissions and toxicity of all emissions and wastes should be reduced as much as possible before they leave the production process.
2. Turn waste into treasure and recycle it. Recycling industrial waste to reduce environmental pollution and harm. Shenzhen Nishi Plastic Products Co., Ltd. adopts the advanced production technology in Japan, uses waste plastics to produce and process all kinds of recycled plastic raw materials, realizes the recycling of plastic resources, and can eat 100 tons of "waste" a day. Baotou Steel Group adopted a sewage recycling system, and the treated water was reused for production, so that all the water was recycled, realizing zero discharge of industrial wastewater in Baotou Steel.
3. Establish waste water and waste gas treatment facilities. Waste water and waste gas must be treated by special treatment facilities before they can be discharged. Some enterprises with small wastewater and waste gas emissions can collect wastewater and waste gas and transport them to professional wastewater and waste gas treatment plants. Enterprises with large emissions must establish their own small wastewater and waste gas treatment facilities.
