Waste and recycling: Value chain, from upstream to the customer
Collecting, sorting and treating waste, returning metals, paper and plastics to use
Value chain, from upstream to the customer
Criticality to the chain: 5 · Chokepoint 4 · Critical 3 · Important 2 · Supporting 1 · Commodity service Stage 1 Generation and segregationHold the legal duty for city waste, set segregation rules and user charges, and award collection, processing and landfill contracts.2
Why critical: Each city has one responsible body, and its budgets and contract decisions decide whether the downstream chain gets paid. Technologies Source segregation rules Integrated solid waste management plans Contract and tender management GPS-tracked collection monitoring Depends on Energy Bld Energy in buildings Industries Public administration, defence and securityFinance: banking, insurance, marketsExamples: Indore Municipal Corporation, Brihanmumbai Municipal Corporation, Greater Chennai CorporationPick, buy and sort recyclables from homes, streets and dumps and sell them up a chain of dealers to recyclers.
Why important: Individual buyers are easy to replace, but the network as a whole carries a large share of India's dry recyclables to recyclers and formal systems would take years to rebuild it. Technologies Manual sorting by material and grade Door-to-door buying Small baling and storage yards Waste picker cooperatives Depends on Energy Mu Muscle powerExamples: SWaCH (Pune), Hasiru Dala (Bengaluru), The KabadiwalaRun door-to-door collection, transfer stations and haulage under municipal or commercial contracts.
Why supporting: Many contractors bid for each city, so a failed operator can be replaced within weeks to months. Technologies Compactor trucks Transfer stations Route optimisation RFID bin tracking Depends on Commodities St Steel Energy Oil Crude oilICV Combustion road vehiclesEV Electric and hybrid vehiclesLPG CNG, LPG and biogas distribution Industries Vehicles, ships, rail, aircraftSoftware and IT servicesExamples: Antony Waste Handling Cell, Re Sustainability, Waste Management Inc, Republic Services, VeoliaSort mixed dry waste into paper, plastics, metals and glass bales and sell them to recyclers, sending rejects to fuel or landfill.
Why supporting: Plants are relatively quick to build and many operators exist, though mixed waste lowers bale quality. Technologies Trommels and ballistic separators Near-infrared optical sorting Eddy-current and magnetic separation Balers Depends on Energy Dist Distribution grids, mini-grids and interconnectorsMot Electric motors and drives Industries Machinery and equipmentExamples: Nepra Resource Management, Recykal, Biffa, VeoliaShred, shear and grade ferrous and non-ferrous scrap from end-of-life vehicles, demolition and industry and sell it to steel mills, smelters and foundries worldwide.3
Why important: A global trade with many sellers, but electric-arc steelmakers depend on it, and scrap use reached about 480 Mt in 2025. Technologies Auto shredders Hydraulic shears and balers Eddy-current separation XRF and LIBS alloy sorting Registered vehicle scrapping facilities Depends on Commodities St SteelAl AluminiumCu CopperPb Lead Energy Mot Electric motors and drivesHVAC AC transmissionShp Ship propulsion Industries Metal productsTransport and logisticsExamples: Sims Limited, European Metal Recycling, Mahindra MSTC Recycling, Nucor (David J. Joseph)Turn baled plastics, waste paper and cullet into recycled resin, pulp and glass that brand owners and mills buy to meet recycled-content and EPR targets.
Why supporting: Many recyclers compete; buyers can switch, though food-grade capacity is scarce. Technologies Washing and regranulating lines Bottle-to-bottle PET Recovered-fibre pulping Cullet processing Chemical recycling pilots Depends on Commodities H₂O Water Chemicals NaOH Caustic sodaPET PET resinSrf Surfactants Energy Dist Distribution grids, mini-grids and interconnectors Industries Plastic and rubber productsPaper and packagingExamples: Ganesha Ecosphere, Indorama Ventures, Veolia, Smurfit WestrockDismantle electronics and batteries and recover lead, copper, gold, lithium, nickel and cobalt for sale to refiners and battery makers.
Why critical: Few authorised plants can recover battery metals at scale, and EPR rules force producers to use them.

Why important: Several technology suppliers, but plants take years to permit and need steady waste with enough calorific value. Technologies Moving-grate incineration Refuse-derived fuel Anaerobic digestion to compressed biogas Windrow composting Flue-gas cleaning Depends on Commodities CaO Lime Chemicals AC Activated carbonNH3 Ammonia Energy WtE Waste-to-energyST Steam turbines and thermal power plantsCBG Biogas and biomethaneLPG CNG, LPG and biogas distribution Industries Machinery and equipmentFinance: banking, insurance, marketsExamples: Jindal Urban Waste Management, Kanadevia Inova, Reworld, Re SustainabilityRun lined landfills and treatment, storage and disposal facilities for residues, industrial and hazardous waste, and remediate legacy dumpsites.4
Why critical: Permits are scarce and few sites exist per state, so hazardous waste generators have little choice.

Why important: High-end optical sorters and shredders come from a small group of mainly European firms.

Why critical: EPR targets and permits create most of the revenue for formal recyclers, so rule changes reshape the market.
