3 Low-Carbon Transition (Peaking) of Chinese Cities: The Case …

Waste incineration does not produce methane emissions, and wastewater emissions
represent approximately 26% of total methane emissions, of which 15% are from
domestic sewage.
There are 38 waste disposal facilities in Beijing, including 10 for sanitary landfill,
11 for incineration and 9 for biochemical treatment. By 2015, about 50% of the
city’s garbage had been incinerated or biochemically disposed of. By the end of the
13th Five-Year Plan period, Beijing could handle 30,000 tons of household waste
per day, which is estimated to reach 38,000 tons by the end of the 14th Five-Year
Plan period.

(1) Beijing will place CH 4 emissions under its control target of greenhouse gases
emissions during the 14th Five-Year Plan period, so that such emissions will be
no higher than 2020. To reduce landfill and increase the share of incineration,
the following measures can be taken: advocate the benefit of garbage classification, heighten the awareness of citizens and teach the skills of classification;
garbage truck operators should collect and sort out waste again before shipment
to increase the calorie value of waste combustion, reduce harmful substances
and improve resource utilization; and promote incineration of household waste.
(2) Scale up CO 2 refrigerant by promoting CO 2 refrigerant + waste heat recovery
and utilization in the eight ice sports venues and large freezers of Beijing Winter
Olympics to cut HFC gas emissions.
3.4.4 Synergy Between Low-Carbon Urban Transformation
and Low-Carbon Winter Olympics in Boosting
the Uptake of “Green Power”
The flexible DC grid pilot project in Zhangbei is a major source of renewable energy
for Beijing Winter Olympics stadiums. It’s the world’s first four-end flexible DC grid
that enables massive transmission of wind, solar and pumped storage energy, capable
of delivering renewable energy from Zhangjiakou to Beijing and Yanqing Olympic
Zone in a safe and efficient manner, facilitating 100% green electricity coverage of
all venues. Meanwhile, the project provides a golden opportunity for tapping into
renewable energy in Zhangjiakou, promoting its coordinated green development with
Beijing.
Expand the import of green electricity. Ramp up the transmission of outside power
to Beijing, so that with the aid of flexible DC grid, the capital can be “light up by the
wind from Zhangjiakou”. The increased power needs, in principle, should be met by
green electricity. By 2025, the total import of green electricity is projected to hit 30
billion kilowatt-hours.
