Objectives:
The specific objectives of the solid waste management (SWM) services
were as follows:
Change the role of the Municipality of Shanghai from being a service
provider to being a service regulator and facilitator by transferring the
responsibility for supplying collection, transportation, treatment and
disposal services to social capital participating organizations.
Recover the cost of providing municipal SWM services form user charges
levied on all waste generators.
Introduce more environmental friendly and cost effective SWM systems
in the city and its surrounding districts in steps with other infrastructure
development

METHODS PRACTISED IN SHANGHAI:
1. LANDFILLS:
• One of Asia’s biggest landfill is in Shanghai, the Laogang landfill.
• The Shanghai Laogang Municipal Solid Waste Landfill is situated at
Laogang town, Nanhui District, southeast of
Shanghai, some 60 km from the city centre.
• It occupies 360 hectares with an anticipated total capacity of more
than 34 million tonnes of waste over a 20-year concession
contract.
• However, although Shanghai possesses sanitary landfills, the
effectiveness of some is nonetheless debated, due to lack of
enforcement of regulations, meaning for example that not all wastes
are sorted and treated before being buried.
• Municipal landfills are, at the moment, the least environmental
solution for the treatment of wastes. They are a hazard to the
landscape, they take up a lot of arable land, they provide high risk of
contamination to surrounding land and water, and also, the methane
produced by the fermentation of the wastes threatens the quality of
the air.
2) INCINERATION:
• Shanghai currently already has several household incineration factories,
including the one of Minhang, which is supposedly the largest one in
China.
• The facility is designed to have a daily garbage handling capacity of 3,000
tons and generate around 270 million kilowatthour of power every year.
• Incineration reduces the volume of waste by 90%, and 80% of its weight.
Furthermore, it reduces the toxicity of the wastes that will then be put
in landfills, and offer the opportunity to
use the energy contained in the waste.
(A Chinese worker controls robotic arms to throw rubbish into an
incinerator at a plant in Shanghai, Southern Hainan province of
China.)
One of the largest waste-to-energy power plant is in Jiangqiao,
Shanghai. It is actually a Sino-French Joint venture between
Shanghai Huancheng Waste-To-Energy Co. Ltd and the French giant
Veolia. Established in 2004, it burns 1,000 metric tons of waste each
day.
3)RECYCLING:
• Although the State does sponsor some kind of
recycling industry, the private and informal activities
constitute the most important mode of recycling.
That is because the informal waste picker relies on
this recycling to resell the materials and make a
living. As such, every thinkable material is
collected, from papers to plastic, electric appliances
to metals, and everything else in between.
RECYCLING GOES IN FOUR STEPS IN SHANGHAI:
1) individuals separate the wastes to their smallest
unit.
2) it is brought to community based waste collection
centres (there are around 200 to 300 of them in
Shanghai)
3) it is then brought to centralized garbage centres
4) it is sent to a plant. (A man collecting recyclable
electronic items in a transfer
station in shanghai,
China)
when wastes are recycled, different kinds of use are found for
them.
• In general, household wastes are reused as fertilizer or
incinerated to produce electricity.
• Industrial wastes are turned into construction materials
• Hazardous wastes are turned into rawmaterials again.
Finding a recycling bin in Shanghai is extremely hard, which
explains the tendency of the inhabitants to dump all the waste
together.
While not quite as color-coded and easy to find municipal treatment
facilities as in the U.S., Japan, and elsewhere, recycling does happen
in China. It’s quite common to see someone dragging a large cart, or
just as often, drive a truck piled dangerously high with recyclables.
Challenges on Solid Waste Management
• Continuing growth of industrial solid waste
- sludge from sewage water plant
- desulfurization gypsum
- denitrification catalyst
- coal ash
- fly-ash sourced from MSW incineration
• Environmental risk prevention & control in the process of HW collection
and transportation
Capability and layout of treatment & disposal facilities need to be
improved and optimized
Capacity building on whole-process monitoring & supervision, risk
prevention & control need to be strengthened
MSW segregation and recycling need to be greatly pushed forward

Challenges faced by
Shanghai:
The representatives of Shanghai are aware of
the gravity of the environmental situation and
are trying to take counter-measures.
However, the challenges Shanghai has to face
are numerous, and involve several social and
political aspects.
The main challenge is rapid urbanization,
which means a fast-growing demand for safe
and clean water in rapidly-modernizing cities
and areas, as local populations continue to
swell with an influx of new arrivals, and as
industry increases consumption. This also
involves upgrading the piping network.
In addition, some parts of the administration
in Shanghai still regard economic growth more
important than the protection of the
environment.
Challenges faced by Shanghai:
Although there is a plan to fight corruption, it is still much
present, and the support of local leaders can sometimes still be bought
by businesses threatened of being shut because of lack authorization or
inadequacy in applying to new laws.
In general, the minimal fees for sewage and municipal waste
collection, and water are a major problem creating a total lack of
incentive from the Shanghainese to improve the situation in these
respective fields.
Outcome from Shanghai EXPO on Solid Waste
Management
• Waste minimization at source: recyclable construction materials,
potable water supply system (reducing 5460 tons of plastic), use of
electronic information technology
Waste segregation and recycling: Two-Bin Waste Segregation-at-
source system; kitchen waste, kitchen oil and non-recyclable waste
were treated separately.
Pneumatic Conveyance System (PCS) for solid waste transportation
•
•
Building Shanghai into a zero waste society
in the future
‡ Waste minimization & segregation at source (MSW safe disposal
rate aims to reach 95% by 2015) ;
‡ Professional transportation system for hazardous waste
‡ Improvement of solid waste treatment & disposal capability
‡ Enhancement of management and supervision
‡ Regulations & Fund
Thanks for your attention!

  • 4. Objectives: The specific objectives of the solid waste management (SWM) services were as follows: Change the role of the Municipality of Shanghai from being a service provider to being a service regulator and facilitator by transferring the responsibility for supplying collection, transportation, treatment and disposal services to social capital participating organizations. Recover the cost of providing municipal SWM services form user charges levied on all waste generators. Introduce more environmental friendly and cost effective SWM systems in the city and its surrounding districts in steps with other infrastructure development

  • 10. METHODS PRACTISED IN SHANGHAI: 1. LANDFILLS: • One of Asia’s biggest landfill is in Shanghai, the Laogang landfill. • The Shanghai Laogang Municipal Solid Waste Landfill is situated at Laogang town, Nanhui District, southeast of Shanghai, some 60 km from the city centre. • It occupies 360 hectares with an anticipated total capacity of more than 34 million tonnes of waste over a 20-year concession contract.
  • 11. • However, although Shanghai possesses sanitary landfills, the effectiveness of some is nonetheless debated, due to lack of enforcement of regulations, meaning for example that not all wastes are sorted and treated before being buried. • Municipal landfills are, at the moment, the least environmental solution for the treatment of wastes. They are a hazard to the landscape, they take up a lot of arable land, they provide high risk of contamination to surrounding land and water, and also, the methane produced by the fermentation of the wastes threatens the quality of the air.
  • 12. 2) INCINERATION: • Shanghai currently already has several household incineration factories, including the one of Minhang, which is supposedly the largest one in China. • The facility is designed to have a daily garbage handling capacity of 3,000 tons and generate around 270 million kilowatthour of power every year. • Incineration reduces the volume of waste by 90%, and 80% of its weight. Furthermore, it reduces the toxicity of the wastes that will then be put in landfills, and offer the opportunity to use the energy contained in the waste.

  • 14. One of the largest waste-to-energy power plant is in Jiangqiao, Shanghai. It is actually a Sino-French Joint venture between Shanghai Huancheng Waste-To-Energy Co. Ltd and the French giant Veolia. Established in 2004, it burns 1,000 metric tons of waste each day.
  • 15. 3)RECYCLING: • Although the State does sponsor some kind of recycling industry, the private and informal activities constitute the most important mode of recycling. That is because the informal waste picker relies on this recycling to resell the materials and make a living. As such, every thinkable material is collected, from papers to plastic, electric appliances to metals, and everything else in between.
  • 16. RECYCLING GOES IN FOUR STEPS IN SHANGHAI: 1) individuals separate the wastes to their smallest unit. 2) it is brought to community based waste collection centres (there are around 200 to 300 of them in Shanghai) 3) it is then brought to centralized garbage centres 4) it is sent to a plant. (A man collecting recyclable electronic items in a transfer station in shanghai, China)
  • 17. when wastes are recycled, different kinds of use are found for them. • In general, household wastes are reused as fertilizer or incinerated to produce electricity. • Industrial wastes are turned into construction materials • Hazardous wastes are turned into rawmaterials again. Finding a recycling bin in Shanghai is extremely hard, which explains the tendency of the inhabitants to dump all the waste together.
  • 18. While not quite as color-coded and easy to find municipal treatment facilities as in the U.S., Japan, and elsewhere, recycling does happen in China. It’s quite common to see someone dragging a large cart, or just as often, drive a truck piled dangerously high with recyclables.
  • 19. Challenges on Solid Waste Management • Continuing growth of industrial solid waste - sludge from sewage water plant - desulfurization gypsum - denitrification catalyst - coal ash - fly-ash sourced from MSW incineration • Environmental risk prevention & control in the process of HW collection and transportation Capability and layout of treatment & disposal facilities need to be improved and optimized Capacity building on whole-process monitoring & supervision, risk prevention & control need to be strengthened MSW segregation and recycling need to be greatly pushed forward • • •
  • 20. Challenges faced by Shanghai: The representatives of Shanghai are aware of the gravity of the environmental situation and are trying to take counter-measures. However, the challenges Shanghai has to face are numerous, and involve several social and political aspects. The main challenge is rapid urbanization, which means a fast-growing demand for safe and clean water in rapidly-modernizing cities and areas, as local populations continue to swell with an influx of new arrivals, and as industry increases consumption. This also involves upgrading the piping network. In addition, some parts of the administration in Shanghai still regard economic growth more important than the protection of the environment.
  • 21. Challenges faced by Shanghai: Although there is a plan to fight corruption, it is still much present, and the support of local leaders can sometimes still be bought by businesses threatened of being shut because of lack authorization or inadequacy in applying to new laws. In general, the minimal fees for sewage and municipal waste collection, and water are a major problem creating a total lack of incentive from the Shanghainese to improve the situation in these respective fields.
  • 22. Outcome from Shanghai EXPO on Solid Waste Management • Waste minimization at source: recyclable construction materials, potable water supply system (reducing 5460 tons of plastic), use of electronic information technology Waste segregation and recycling: Two-Bin Waste Segregation-at- source system; kitchen waste, kitchen oil and non-recyclable waste were treated separately. Pneumatic Conveyance System (PCS) for solid waste transportation • •
  • 23. Building Shanghai into a zero waste society in the future ‡ Waste minimization & segregation at source (MSW safe disposal rate aims to reach 95% by 2015) ; ‡ Professional transportation system for hazardous waste ‡ Improvement of solid waste treatment & disposal capability ‡ Enhancement of management and supervision ‡ Regulations & Fund
