Before introduction of waste separation, discharged household waste was
transported to the single landfill in Pujiang Prefecture and disposed of through
“dispersed” collection. In terms of processing, in keeping with the concept of local
production for local consumption, waste that can be recycled into resources is
instead preferentially transported to a nearby waste disposal center for processing,
and only the remaining waste is transported to the landfill. According to 2016 data,
the amount of waste transported to the waste disposal plant was reduced from
514 tons to 355 tons, and the transferring cost reduced from 55,100 to 38,100 CNY.
18.4.1.4 Reduction in Landfill Disposal Costs
If the proportion of raw garbage in total waste is large, the amount of organic
substances that decompose in the filtrate will increase, and the processing cost of
the filtrate will increase. Conversely, if raw garbage is removed before landfill
disposal, processing costs decrease. According to data from the Pujiang Prefectural
Health Bureau, the disposal cost after separation is about 7040 CNY.
18.4.1.5 Increased Cost of Waste Collection Processing
Raw waste is transported to a nearby processing center where it is recycled into
organic fertilizer by a waste-processing machine. The cost of transporting 158 tons
of waste a day is approximately 4700 CNY, and the cost of producing organic
fertilizer is approximately 8300 CNY. In total, the transfer processing cost of raw
garbage will be approximately 13,000 CNY.
As described above, even if the predicted costs for transferring and processing
raw garbage are incurred, the overall waste disposal costs are reduced through
reducing waste collection costs, landfill waste transfer costs, and landfill waste costs.
18.4.2 Economic Effects of Recycling
As shown in the flow chart for processing waste in Pujiang Prefecture (Fig. 18.3),
raw (rotting) garbage is fermented and decomposed in a short time using a microbial
fungus agent in waste mechanical fermentation equipment. In 10 days, approximately 511 kg of organic fertilizer can be produced from 2 tons of waste. Currently,
this is provided free of charge to farmers in Pujiang County in order to incentivize
them to separate their waste, but in the future it will be sold. According to a report
from August 2018 (Pujiang County, Zhejiang), approximately 200 tons of raw
garbage was processed per day in 2017, producing organic fertilizer worth three
million CNY by the end of the year. Recyclable waste, which was originally
disposed of by villagers under the two-time sorting system and mixed with general
waste, is now sorted and collected by cleaning staff. Approximately 1 ton of
