At least 254 National People's Congress deputies in Shenzhen have signed a joint petition calling for cooperation between Hong Kong and Shenzhen to solve the SAR's waste problem near the border.
Shenzhen residents have been complaining of the odor from the Tuen Mun landfill, located only 16 kilometers from Shekou in Shenzhen.
According to online media Shenzhen News, the petition urged the SAR to respect public opinion in Shenzhen and that the two governments set up a mechanism to deal with the garbage problem.
They hoped Hong Kong will change the methods used in landfills as the main way to deal with waste and adapt new technologies to reduce trash.
The deputies said the 3R method - Reduce, Reuse and Recycle - is widely being used in western countries.
NPC member Huang Xiang said: "Our lives are equal and both governments should face the problem."
The director of the Xiaping Landfill in Shenzhen, Liang Shun-wen, said landfills in Hong Kong are mostly in the northwest and east, and with Shenzhen in the southeast, it faced the downside wind. He also said that if landfill leachate was not dealt with properly, it could pollute Shenzhen Bay.
An expert in the Chinese Academy of Sciences, Chen Neng-chang, said the Japanese government did a good job in sorting out garbage and there are websites to teach citizens how to sort garbage of up to 1,400 categories.
The Chief Secretary for Administration Carrie Lam Cheng Yuet-ngor and Shenzhen mayor Xu Qin attended a meeting to strengthen cooperation between the two places on November 25.
