recyclable waste is collected each day, worth approximately 400 CNY or 146,000
CNY per year.
The collection and disposal costs before and after separating garbage can be
reduced by 9.636 million CNY per year. In addition, an annual profit of 146,000
CNY can be generated from the sale of recyclable waste, enabling the production of
organic fertilizer with a total value of three million CNY. Thus, the annual profit
obtained by waste separation is estimated to be approximately 12.8 million CNY.
18.4.2.1 Reduction of Financial Burden in Waste Separation Processing
The cost of government waste disposal in rural areas of China has increased sharply
since 2013, becoming a heavy burden on local government finance. Until 2013,
waste disposal costs were not included in hygiene management costs and were not
separately disclosed. The release of separate statistics on these costs since 2013 is an
indication of increasing government focus on waste disposal problems. It became
clear that the financial burden of waste disposal could be reduced by implementing a
new waste separation disposal system in Pujiang Prefecture. Inhabitants could also
obtain economic and social benefits by collecting resource waste and receiving
organic fertilizer free of charge.
In addition to reducing the financial burden on the government, waste disposal
can also benefit private companies and residents. As waste disposal costs are
expected to continue to increase in the future, the Pujiang model is expected to be
applied to other regions in China.

18.4.3.1 Waste Reduction by Intermediate Treatment
In 2016, the total amount of general waste, excluding industrial waste, collected in
Pujiang County was approximately 900 tons per day, of which approximately
514 tons was domestic waste. As a result of the separation process, 158 tons of
raw garbage is made into organic fertilizer by intermediate disposal of household
waste, and approximately 1 ton of resource waste is collected (Fig. 18.4).
The amount of waste finally transported to landfill is approximately 355 tons. The
reduction of process waste by intermediate treatment is about 31 percent. The
amount of industrial waste finally transported to landfill is 95 tons, due to the
separate collection of raw garbage and recyclable waste, and the amount of waste
finally entering landfill is 450 tons. The rate of waste reduction due to intermediate
disposal has reached 50%. This reduction in weight doubles the useful life of the
landfill. Since all waste that cannot be recycled is landfilled directly as landfill waste,
problems such as soil pollution and wasted land resources remain; therefore an
incineration facility was not constructed. It is expected that the rate of waste
