Waste Management Booming

Several sculptures made from cans, tires and plastic bottles     1     (display) around a recyclable transfer center in Shanghai last year. The idea of making sculptures with trash is to make people aware that trash can be useful when     2     (sort) properly.

It was in 2018，when President Xi Jinping emphasized the importance of trash classification，

    3     the initiative(倡议) started to get on the fast track. The question “What kind of trash are you（carrying）?”became a popular joke when Shanghai enforced a law that household waste is required to be sorted     4     four categories：recyclables, kitchen, hazardous(危险的) and residual waste.     5     many people doubted it initially, the trash sorting program has achieved great success. Moreover, in the     6     (propose) for the 14th Five-Year Plan(2021—2025), the Central Committee said the country should speed up the building of waste recycling systems.

Besides the efforts made by the government, many companies are entering the trash separation and recycling market. Huazhan Environment,     7     high-tech company in Jiangsu province, launched a new brand, Mr. Cat in English, selling intelligent trash stations and bins to communities.     8     (equip) with cameras, sensors and screens, the smart trash stations are     9     (interact) and help people     10     (reasonable) deal with different kinds of trash.

3 . China still dumps most of the garbage it generates in landfills, which could pollute soil, water and air. Today, China is facing a problem similar to the one Japan faced in the 1970s, especially in its coastal cities which have a relatively high economic growth rate and a large population but comparatively limited land space, resulting in serious environmental pollution.

China has just started its garbage sorting journey, and it will take time for the people to make it a habit of sorting garbage at source.

Shanghai is among China's first cities to introduce garbage classification and also the country's most serious in its performing. Since July 1, 2019, Shanghai residents have been required by law to sort garbage into four different categories, or they could face fines. Individuals, including tourists, can be fined up to 200 yuan for failing to sort their waste properly, while companies and institutions can be fined up to 50，000 yuan.

The city government has set up online apps to handle sorting questions, and announced guidelines to address the "one-size-fits-all" method. The country is about to invest over 21 million yuan in the construction of garbage processing facilities to meet demands.

Following Shanghai, Beijing is also pushing ahead with garbage sorting legislation (立法) in the continual national action to get all of China sorting garbage. Not forced yet, the Chinese capital is already carrying out garbage sorting in more than 200 residential communities and it's trying to get more residents on board by making the system smarter. Now it's introducing artificial intelligence into its waste management system, by setting up little cameras in many sets of bins.

However, not every face can be recognized by the smart dustbin until you register (注册) for the system. Once registration is complete, users will scan a QR code on the bin, which then opens it up to allow for garbage disposal (处理). Now, each household gets one special QR code for throwing out waste. Here, the intelligent bins don't just calculate garbage weight, they also help residents gain rewards by collecting points through the special app.

China welcomes the age of compulsory garbage sorting with its cities revising laws on garbage classification. For Shanghai, sixty percent of the city is expected to implement garbage sorting by the end of this year, and 90 percent by 2020. Garbage sorting is, without doubt, a costly but worthwhile commitment. It is good for the environment and essential for the country's long-term development, and may finally turn out to be a promising industry as well.
