Dynagreen Environment Protection Group, a Chinese company that collects, stores and incinerates garbage, has surged nearly 500 percent since it began trading in Shanghai in June.
The Chinese government just announced that for the first time, households will have to pay for garbage disposal by 2020. It also is tightening limits on landfills.
Since the first half of the year, China signed about 100 billion yuan ($14.6 billion) of sanitation and classification contracts, according to environment consulting firm Huanjing Sinan. And the deals keep coming.
