　　BEIJING, June 3 (Xinhua) -- Xi Jinping, general secretary of the Communist Party of China (CPC) Central Committee, president of the country and chairman of the Central Military Commission, recently gave important instructions on garbage classification. Xi Jinping stressed that the implementation of waste separation, the majority of the people's living environment, the conservation of the use of resources, but also an important reflection of the level of social civilization.

　　Xi Jinping pointed out that the implementation of waste separation, the key is to strengthen scientific management, the formation of long-term mechanisms, to promote the habit of formation. To strengthen the guidance, according to local conditions, continue to promote the work to do a detailed and practical, persistent grasp. To carry out extensive education and guidance work, so that the majority of the people realize the importance and necessity of the implementation of waste separation, through effective supervision and guidance, so that more people take action to develop good habits of waste separation, the whole society, everyone's hands, together to improve the living environment for the effort, together to contribute to green development, sustainable development.

　　In December 2016, he chaired a meeting of the Central Leading Group of Finance and Economics to study the universal implementation of the garbage classification system, stressing the need to accelerate the establishment of a garbage treatment system of sorting, collecting, transporting and disposing of garbage, forming a garbage classification system based on the rule of law, government promotion, universal participation, urban and rural coordination and local adaptation, and striving to improve the The system covers a wide range of areas. Xi Jinping has also repeatedly learned about the work of garbage classification at the grassroots level and made clear requirements for this work.

　　In recent years, China has accelerated the implementation of the garbage classification system, the national garbage classification work from point to point, gradually launched, the first results, 46 key cities first pilot, to promote the positive progress of garbage classification. 2019 onwards, the country's prefecture-level and above cities to fully launch the work of domestic garbage classification, by the end of 2020 46 key cities will be basically built garbage classification system, by the end of 2025 National prefecture-level and above cities will be basically built garbage classification and treatment system.

According to the instructions of our Hubei Xian Crystalline Chemical for waste classification training and learning, through the study we learned how to classify garbage, the benefits of waste classification, the impact of waste classification on our living environment. Specifically, we learned together.

How to sort the garbage exactly?
　　Waste classification and recycling is of great significance to protect the environment and save resources; it is understood that 1 ton of waste paper can make 850 kg of good paper, saving 4 cubic meters of wood and reducing pollution by 74% compared to the equivalent production; 1 ton of waste plastic can refine 300 kg of unleaded gasoline and diesel; 1 ton of waste steel can refine 750 kg of good steel; 1 ton of waste glass can make 20,000 glass bottles of 500 grams capacity... Let's see how the garbage is sorted.

Recyclable waste

　　(B) mercury containing class
　　Waste fluorescent tubes, waste energy-saving lamps, waste silver thermometers, waste silver sphygmomanometers, fluorescent sticks, etc.

Each of us is a producer of garbage.
We are all victims of garbage, and we are all victims of garbage.
Each of us should be the one to control the garbage.
Let's join hands and participate in waste separation.
Let's build our green and beautiful home together!
