Plastic Products, PlasticWaste andResource Recovery [2020]
Background information and notes on the publication of the Flowchartof Plastic Products, Plastic Waste and Resource Recovery (2020)

This fiscal year, to improve the accuracy of the Flowchart of
Plastic Products, Plastic Waste and Resource Recovery, Plastic
Waste and Resource Recovery, the following improvements andassessments were performed.
(1) Revision to amount of mechanical recycling
We had not updated the calculation scheme for the amount of
mechanical recycling originating in post-use products for sometime. We therefore summed up the amount of mechanical recyclingby identifying as much as possible post-use products subjected tomechanical recycling and closely checked those amounts based ona variety of statistics.
(2) Revision to amount of mechanical recycling products
Up to now, Japan has been exporting mechanical recycling
products (mainly intermediately processed scrap plastic) in large
volumes to overseas locations (mainly China), but due to enhanced
plastic-waste import restrictions imposed by China in 2018, theamount of exported mechanical recycling products (the amount ofexported “scrap plastic” according to Japan trade statistics)
decreased significantly. On the other hand, it was surmised, forexample, that cases in which mechanical recycling products were
exported in the form of recycled material such as pellets, which is
not grasped by those trade statistics, had actually increased. To
therefore grasp the export state of mechanical recycling products(= scrap plastic + recycled material), we determined, for main
resins (polyethylene, polypropylene, and polystyrene), the amountof exported recycled material by subtracting the “amount ofexported resin material not including recycled material” as grasped
and announced by the Japan Petrochemical Industry Associationfrom the “amount of exported resin material including recycledmaterial” as obtained from trade statistics. Then, on conducting
interviews with exporters and industry associations, we added theamount of exported recycled material for collected resins otherthan the above main resins to calculate the amount of recycledmaterial exported overseas in a form other than scrap plastic. In
2020, this amount reached 620 kt, and it became clear that thetrend in producing recycled material within Japan and exporting it
overseas had been strengthening amid the gradual weakening of
the trend in exporting scrap plastic to countries other than China(mostly Southeast Asian countries), which had strengthened
immediately after China imposed enhanced plastic-waste import
restrictions. The amount of mechanical recycling products
calculated by adding the amount of exported “scrap plastic” fromtrade statistics to this amount of exported recycled material came
to 1,360 kt, so it appears that nearly 80% of mechanical recycling
products were exported overseas.
From the perspective of material balance in plastic waste, aportion of plastic waste used in mechanical recycling is exported
overseas as scrap plastic and recycled material, while recycled
products using plastic waste other than the above are produced andused domestically (recycled) (appearing in the following year’s
flowchart). A rough value for the amount of recycled products
circulating domestically can therefore be estimated by subtracting
the amount of exported mechanical-recycling products from theamount of mechanical recycling. To verify this calculation, we
estimated the amount of recycled products based on the obtained
amount of exported mechanical recycling products and found thatit generally agreed with the amount of “Plastic Waste Products”
from the Ministry of Economy, Trade and Industry, Industrial
Statistics, in relation to the domestic shipping of recycled resin.

2020 Highlights(1)For 2020, resin production and domestic plastics products consumption decreased significantly to 9,630 kt and 8,410
kt, respectively, due to the effects of the COVID-19 pandemic.
(2)Total plastic waste discharge decreased to 8,220 kt.
(3)Effectively used plastic waste was 7,100 kt making for an effective plastic utilization rate of 86%, one point higher
than that of the previous year.
In 2020, the demand for plastic products decreased due torestrictions in production activities and a drop in consumption
brought on by the effects of COVID-19. As a result, resin
production, resin import, and domestic plastics products
consumption all decreased significantly to 9,630 kt (-870 kt
relative to 2019; -8.3%), 2190 kt (-300 kt; -12.2%), and 8,410 kt(-980 kt; -10.4%), respectively. On the other hand, the number ofexported automobiles decreased and exported plastic parts fromassembled products decreased to 480 kt (-170 kt; -25.9%) so thatdomestic plastic input came to 8,370 kt (-810 kt; -8.8%) thereby
reducing somewhat the extent of its decrease. In addition, total
plastic waste discharge decreased to 8,220 kt (-280 kt; -3.3%). On
breaking down total plastic waste discharge, domestic (general)
waste was mostly unchanged at 4,100 kt (-20 kt; -0.6%) sinceconsumption did not relatively decrease due an increase in demandfor products related to staying at home and hygiene. However,production and processing waste discharged from factories andelsewhere decreased due to restrictions in production activities, so
industrial waste decreased significantly to 4,130 kt (-260 kt;-5.8%).
As for disposal and recovery methods, mechanical recycling
decreased to 1,730 kt (-120 kt; -6.7%), feedstock recycling *1
increased to 270 kt (+10 kt; +2.5%), and energy recovery *2

decreased in total to 5,090 kt (-40 kt; -0.8%), and effectively usedplastic waste decreased to 7,100 kt (-160 kt; -2.2%) partly due todecrease in total plastic waste discharge. This decrease inmechanical recycling can be attributed to the apparent decrease(-40 kt) associated with the “Revision to amount of mechanicalrecycling” in our study performed this year on improving theaccuracy of the flowchart, as well as to the decrease in mechanicalrecycling originating in production and processing waste (-50 kt
relative to 2019) and the decrease in mechanical recycling of PET
bottle waste (-20 kt). At the same time, simple incineration andunused plastic waste by landfilling together decreased to 1,120 kt(-120 kt; -9.8%). The percentage contributions to the effective
plastic utilization rate by mechanical recycling, feedstock
recycling, and energy recovery were 21% (-0.8 points to 2019),
3% (+0.2 points), and 62% (+1.6 points), respectively, resulting inan overall one-point jump from the previous year to 86%. The
main reason for this increase is given to be the increase in the useof densified-refuse derived fuel (+120 kt; +13.5%).
*1:feedstock recycling = blast/coke furnaces + gasification(chemical materialuse) + liquefaction*2:energy recovery = gasfication(fuel use)+densified-refuse derived fuel and cement
material/fuel + incineration with power generation + incineration with heatutilization facility

Explanation of flowchart items(1) Resin production, resin processing,and marketing of products
1-1 Resin production

・This figure was estimated on the basis of chemical-industry
statistics from the Ministry of Economy, Trade and Industry(METI). Note that (synthetic) resin does not include synthetic
rubber or synthetic fiber.
1-2 Reclaimed products
・For convenience sake, this figure was estimated assuming thatthe domestically used portion of the previous year’s produced
mechanical recycling products (recycled resin) is used in thecurrent year while taking figures such as the amount of exported
recycled resin into account.
1-3 Domestic plastic products consumption
・(domestic plastic products consumption) = (resin production) –{(resin export) – (resin import)} – (liquid resin, etc.) – {(resin
processing waste) – (reclaimed products)} – {(product export) –(product import)}
・Resin export/import figures are based on trade statistics from the
Ministry of Finance.
・Figures for liquid resin, etc. such as additives and paints that falloutside the scope of plastic waste at the time of discharge arebased on chemical-industry statistics from METI.
・Figures for plastic product export and import are based on trade
statistics from the Ministry of Finance.

2・Resin processing waste refers to discharged waste from theprocessing step that is not turned into products.
1-4 Domestic plastic input
・( d o m e s t i c p l a s t i c i n p u t ) = ( d o m e s t i c p l a s t i c p r o d u c t s
consumption) – {(exported plastic parts from assembled
products) – (imported plastic parts from assembled products)}
・Assembled products: automobiles, home appliances (televisions,refrigerators, freezers, air conditioners, washing machines anddryers)・Number of exported/imported assembled products: Automobile
figures were determined from an automobile database (Japan
Automobile Manufacturers Association (JAMA)); home
appliance figures were based on “Current Production Statistics”
from METI.

(2) Discharge
2-1 Post-use products discharge
・This figure is calculated by a PWMI estimation system based on
domestic plastic input by demand-generating fields and by resin
type (usage quantities have been calculated annually from 1976)
and on a new product discharge model by demand-generating
fields (“100-year discharge model” formulated by PWMI in2017).
・ Since the export of used automobiles or used home appliances
affects post-use products discharge in Japan, corrections weremade to plastic waste discharge in the transport industry or theelectronics/electronic-equipment industry. Here, the number ofexported used automobiles was based on data released by theJapan Automobile Dealers Association while the number ofexported used home appliances was based on “2017 Flow
Estimation Results” in the “Current State of the Implementationof Recycling Based on the Home Appliances Recycling Act”
prepared by the Ministry of Economy, Trade and Industry(METI) and Ministry of the Environment (MOE).
・Discharge ratios for domestic waste and industrial waste were
estimated using a new product discharge model by demandgenerating fields (formulated by PWMI in 2017).
2-2 Production and processing waste discharge
・Amount of resin production waste (resin discharged as waste in
the resin-production stage) is not included in the amount of resin
production. The amount of resin production waste and amountof resin processing waste were each estimated using a prescribed
waste ratio.In addition, we used a new value for the productionwaste ratio calculated from the results of the survey conductedby PWMI in fiscal year 2018.
2-3 Total plastic waste discharge
・(total plastic waste discharge) = (post-use products discharge) +(resin production waste) + (resin processing waste)
2-4 Breakdown of total plastic waste discharge by resin type・These breakdown figures were estimated from amounts of postuse products discharge, production and processing waste
discharge, resin production, etc.

(3) Disposal and recovery
3-1 Mechanical recycling
・Figures for the mechanical recycling of domestic plastic
waste were based on the weight of collected PET bottles(The Council for PET Bottle Recycling) and weight ofcollected white trays (Japan Plastic Food Container
Industry Association), and figures for the mechanicalrecycling of other plastic containers and packaging as
specified by the Containers and Packaging Recycling
Law were based on data released by The Japan
Containers And Packaging Recycling Association.
Residual amounts after the mechanical recycling of otherplastic containers and packaging were allocated todensified-refuse derived fuel using figures released by
The Japan Containers And Packaging Recycling
Association as coeﬃcients.
・The amount of mechanically recycled industrial waste
was determined by subtracting the amount of
mechanically recycled domestic waste from the total ofmechanical recycling originating in post-use products(revised in fiscal year 2021) and mechanical recycling
originating in production and processing waste estimatedfrom statistical figures of industry associations.
Furthermore, based on the results of the survey
conducted in 2018, the amount of mechanically recycled
production waste was set to approximately 70% from the2018 flowchart on while the amount of mechanicallyrecycled processing waste was set to approximately 60%
from the 2019 ﬂowchart on.
・Recycled resin = scrap plastic + recycled material +recycled products. Scrap plastic refers to plastic waste
subjected to intermediate processing (crushing, washing,etc.) as an objective of mechanical recycling. Recycledmaterial, meanwhile, refers to pellets, ingots, ﬂakes, ﬂuﬀ,
etc., while recycled products refer to shipping pallets,building materials, miscellaneous daily goods, etc.

・The export ﬁgure for recycled resin was taken to be thetotal export figure for scrap plastic and recycledmaterial. The amount of exported scrap plastic was
calculated after correcting the amount of exported scrap
plastic based on trade statistics from the Ministry of
Finance. In addition, the amount of exported recycledmaterial was calculated using trade statistics from the
Ministry of Finance in relation to resin material andstatistics from the Japan Petrochemical Industry
Association. Moreover, the amount of imported scrap
plastic, though being small enough to be ignored, wasstill a statistical ﬁgure and therefore subtracted from theamount of export, but the amounts of imported recycledmaterial and exported recycled products were ignored.
3-2 Densified-refuse derived fuel and cement material/fuel,blast/coke furnaces, gasification, and liquefaction
・Figures for densified-refuse derived fuel includes plastic waste
for power generation; figures for densified-refuse derived fueland cement material/fuel are based on the results of surveys
covering respective industry associations.
・Figures for blast furnace raw materials, coke-oven chemicalmaterials, gasification, and liquefaction approved as productrecycling methods by the Containers and Packaging Recycling
Law are based on data released by The Japan Containers And
Packaging Recycling Association. Associated figures for industrial
waste were based mainly on the results of questionnaires.
3-3 Incineration/landfilling of domestic waste
・Incineration/landfilling ratio
This figure was estimated using the results of PWMI surveys
based on figures in the “FY2016 Nation Survey on the State ofDischarge and Treatment of Municipal Solid Waste” released by
the Ministry of the Environment.
・Incineration with power generation, incineration with heatutilization, and simple incineration of domestic waste“Incineration with power generation” means incineration
processing by an incinerator equipped with power-generation
facilities, “incineration with heat utilization” means incineration
processing by an incinerator that, while not equipped withpower-generation facilities, has facilities for utilizing heat
externally, and simple incineration means incineration
processing by an incinerator other than that above. The ratios
shown were estimated using the results of PWMI surveys basedon values released by the Ministry of the Environment.
3-4 Incineration/landfilling of industrial waste
・The disposal and recovery of industrial waste is partiallycommissioned to local governments as business-related
waste. Here, for the ratio of such processing by business
operators to that commissioned to local governments, weused a new value calculated from the results of thesurvey conducted in fiscal year 2018. The percentage
breakdown of commissioned processing into incineration
with power generation, incineration with heat utilization
facility, simple incineration, and landﬁlling was based on
ﬁgures for domestic waste processing.
・For business operators, the incineration/landﬁlling ratio
and the percentage breakdown of incineration processing
into incineration with power generation, incineration
with heat utilization facility, and simple incineration were
new values calculated from the results of the survey
conducted in ﬁscal year 2018.
・Figures for incineration with power generation includes plastic
waste traded for a price.
