China's largest waste landfill in Northwest China's Shaanxi Province will be closed soon, and an ecological park is expected to be built on the site.

The Jianggoucun waste landfill in Xi'an, Shaanxi, built in 1994, reached saturation 20 years in advance, CCTV reported on Wednesday.

The landfill processes 10,000 tons of rubbish every day, the most in China. Its designed daily filling amount was around 2,500 tons and should be in use for 50 years according to original plan.

According to CCTV, the landfill equals an area of 100 soccer fields. Its depth is 150 meters.

Sun Jianjun, who is responsible for processing the rubbish in Xi'an's city administration bureau, said the landfill will be closed and the ecology there will be recovered. "This place will become a large ecological park and reopen to the public with a better environment," he said.

After the landfill is closed, an electric power generation by a waste incineration project will take over its task. Three incinerators that can process 750 tons of waste have been launched on November 4, which could deal with more than 2,000 tons of household garbage. The incineration process is innocuous, according to the CCTV report.

By the end of 2020, a total of five innocuous incineration projects could be put into use in Xi'an, processing 12,750 tons of waste daily.

The city has vowed to implement  a waste sorting system this year. Domestic waste is required to be sorted into four categories: dry refuse, wet trash, recyclable waste and hazardous waste. Those who fail to sort garbage and refuse to comply can be fined.

By 2025, the more than 300 Chinese cities at or above the prefecture level shall complete the building of garbage sorting and processing systems, according to the Xinhua News Agency.
