2021 Highlights(1) Despite the ongoing effects of the COVID-19 pandemic, an economic recovery began to take hold. At 10,450 kt, resin
production nearly returned to its 2019 pre-pandemic figure, and at 9,000 kt, domestic plastics products consumption
increased from the previous year.
(2) Total plastic waste discharge was about the same at 8,240 kt.
(3) Effectively used plastic waste increased by 70 kt from the previous year to 7,170 kt and the effective plastic utilization raterose by about one point over the previous year to 87%.
In 2021, a recovery trend could be seen in production activity
despite the ongoing effects of behavioral restrictions associatedwith the COVID-19 pandemic, and due to a growing demandfor plastic products, resin production for 2021 increased fromthe previous year to 10, 450 kt (+820 kt relative to 2020; +8%).
In addition, resin export, and resin import, increased to 3,910 kt(+180 kt; +5%), 2,370 kt (+180 kt; +8%), respectively. As aresult, domestic plastics products consumption increased to
9,000 kt (+580 kt; +7%).
Product export, and exported plastic parts from assembled
products increased, so domestic plastic input increased to 8,870
kt (+490 kt; 6%).
On the other hand, total plastic waste about the same at 8,240
kt (+20 kt; ±0%). On breaking down total plastic waste
discharge, domestic (general) plastic waste increased to 4,190 kt(+100 kt, +2%), and Industrial waste, on the other hand,decreased to 4,050 kt (-80 kt, -2%).
In terms of disposal and recovery methods, mechanicalrecycling increased to 1,770 kt (+40 kt; +2%), feedstock
recycling*1 increased to 290 kt (+20 kt; +7%), and energy

recovery*2 increased in total to 5,110 kt (+20 kt; ±0%).
As a result, effective plastic utilization decreased to 7,170 kt(+70 kt; +1%) from the previous year. At the same time, simple
incineration and unused plastic waste by landfilling together
decreased slightly to 1,070 kt (-50 kt; -5.0%). Additionally, inthe breakdown of mechanical recycling, the export of scrap
plastic came to 560 kt (-180 kt; -24%) while the export ofrecycled material came to 750 kt (+130 kt; +21%). A growing
trend can therefore be seen in the processing of scrap plastic
and its export as recycled material due to the effects ofamendments to the Basel Convention and other regulations. The
percentage contributions to the effective plastic utilization rateby mechanical recycling, feedstock recycling, and energy
recovery were 21%, 4%, and 62%, respectively, resulting in a
one-point up from the previous year to 87%.
*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.
・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: transportation related products (mainly
automobile), Electrical and electronic equipment (mainly home
appliances)
・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 theelectronics/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, was still astatistical figure and therefore subtracted from the amountof import, but the amount of imported recycled products
was ignored. Furthermore, since the amount of imported
recycled material and the amount of exported recycled
products were already recorded in the amount of imported/
exported resin and products, they were not included in thiscalculation.
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 “FY2020 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.
