    If you live in Shanghai, you might have to take a “lesson” in sorting garbage (垃圾分类), as the city recently introduced new garbage-sorting rules.

It’s  now  required that  people  should  sort  garbage  into  four  groups,  namely  recyclable, harmful, dry and wet waste. However, if people fail to sort their garbage properly, they can be fined up to 200 yuan.

More cities are introducing similar rules, following the practice in Shanghai. By the end of 2020, garbage-sorting systems will have been built in 46 major Chinese cities, including Beijing and Shenzhen, reported People’s Daily.

According to a study by the Policy Research Center for Environment and Economy, under the Ministry of Ecology and Environment, over 90 percent of the public believe that garbage sorting is important for the protection of the environment.

However, garbage sorting is still a big problem in China. Only 30 percent of participants(参加者) said they think they are adequately sorting their garbage, the study noted.

According to Xinhua News Agency, it’s partly because many people lack the willingness to sort their own waste. In the past, some garbage rules didn’t give clear fines for people who failed to sort garbage.

“It’s a must to have a legal guarantee (法律保障) to support garbage sorting,” Liu Jianguo, a professor from Tsinghua University, told China Daily.

Liu Xinyu, a researcher of the Shanghai Academy of Social Sciences, told China Daily that the importance of the new rules in Shanghai is to change the past voluntary action into compulsory action for everyone.

Besides China, many other foreign countries have also introduced garbage-sorting rules. In Japan, waste sorting has become a basic survival skill, reported Xinhua. There is a fixed time to deal with each kind of garbage and littering can result in high fines and being sentenced in prison.

In Germany too, people are asked to sort waste into specific groups, reported HuffPost. For example, in Berlin, people have yellow dustbins for plastic and metals and blue dustbins for paper and cardboard.
