18.3.2.4 The Role of Residents
The residents of Pujiang County separate and dispose of household waste under the
guidance of party members. Farmers use organic fertilizers created from recycled
waste to grow organic products and consume agricultural products.
18.4 Evaluating the Sustainability of the Pujiang Model
The method of collecting waste has changed from conventional waste disposal
(before separation) to a new waste disposal format (after separation). Compared
with the cost of mixed collection and separation processing in the conventional
system, separated collection and resource recovery processing can significantly
reduce costs including those of waste collection and transportation and labor.
According to data from the Pujiang government, daily waste emissions were about
514 tons in 2016. Considering the change in the cost of collecting 514 tons of waste
before and after introduction of the new system, the collection of resource waste, and
the value of the organic fertilizer produced, the economic benefits of waste separation (currently all organic fertilizers are distributed free of charge to residents of
Pujiang County) can be estimated at approximately 39 million CNY per year.
18.4.1 Reduction in Waste Collection Processing Costs
The daily cost of waste disposal in this area is approximately 10% lower than the
costs of mixed collection and mixed processing in the conventional system. The
main reasons for the reduction in costs after separation are reduction in collection
cost, reduction in transfer cost, and reduction in disposal cost. Although there is a
cost to separating waste, this is less than the reduction in other associated costs. In
2016, the daily cost of waste disposal was 26,400 CNY (Fig. 18.2), equivalent to an
annual reduction in costs of approximately 9.636 million CNY.
18.4.1.1 Collecting and Processing Costs Before Waste Separation
Before waste separation began in 2014, there was one garbage bin for every eight
households in the town, and cleaners collected waste from each garbage bin and
public places and carried it to the waste relay station. After that, it was transported to
“town” by a waste transport vehicle, transferred from “town” to “prefecture,” and
was disposed of at the “prefecture” landfill site. In this centralized collection process,
all waste was collected and disposed of at the landfill. We calculated the processing
costs had this centralized system been in place in 2016 to be 174,000 CNY for
