A buyer comparing PyOil purely by finished-product label, plastic-derived versus tire-derived, is skipping the constraint that actually narrows the field first.
Within the global PyOil market, feedstock purity is the quality decision made first, since whether a waste stream is single-polymer or a mixed, multi-layer blend determines which of the seven PyOil type categories are even achievable before a producer considers technology configuration.
This page describes seven PyOil type categories and seven feedstock source categories strictly as market segments.
It provides no pyrolysis engineering or plant-design guidance, and makes no claim about environmental, safety or regulatory-compliance effectiveness beyond naming certification schemes as market-access categories.
A feedstock stream dominated by a single resin, clean polyethylene film for instance, will generally yield a more consistent PyOil grade than a mixed, multi-layer or contaminated stream, regardless of which technology configuration a facility otherwise runs.
That is why producers experienced in this market lead feedstock qualification with purity and polymer composition rather than with a preferred PyOil type label alone.
Seven feedstock source categories complete the picture once PyOil type is understood, spanning post-consumer plastic waste, post-industrial plastic waste, packaging film waste, flexible plastic waste, agricultural plastic waste, automotive plastic scrap and municipal mixed plastic streams.
Post-consumer and post-industrial plastic waste together represent the feedstock sources most frequently paired with plastic-derived and mixed polyolefin PyOil, reflecting their established position across standard collection and sorting networks.
Flexible plastic waste and multi-layer plastic feedstock present the harder qualification path, since multiple resin layers and additives complicate consistent conversion, which is precisely why chemical recycling is positioned as the recovery route mechanical recycling cannot serve for these streams.
Contamination from residual metals, moisture and chlorine-bearing polymers such as PVC lowers achievable yield and can foul downstream equipment, which is why feedstock qualification typically screens for these contaminants before a supply agreement is finalised.
Producers generally validate a new feedstock source through lab-scale or pilot-scale trial batches before committing to commercial-volume contracting, confirming yield and product specification hold consistently across multiple deliveries rather than a single sample.
Feedstock qualification typically also examines ash content and moisture level, two properties that affect reactor performance independently of resin type or contamination from foreign polymers.
Producers that document feedstock composition consistently over time can generally negotiate more favourable offtake terms, since a buyer places a genuine premium on predictable input quality when planning its own downstream production schedule.
Plastic-derived pyrolysis oil is the broadest PyOil type category, covering pyrolysis oil recovered from general plastic waste streams without a narrower resin-specific qualification attached.
Mixed polyolefin pyrolysis oil narrows that category to polyethylene and polypropylene blends specifically, the two resin families that dominate flexible packaging and rigid container waste across both regions.
Polyethylene-derived PyOil and polypropylene-derived PyOil narrow the category further still, each describing pyrolysis oil recovered from a single resin family rather than a blend.
Single-resin PyOil categories generally command tighter, more predictable specification windows than blended categories, since a known polymer composition simplifies downstream product-output planning covered on the products and end-use page.
Buyers seeking consistent feedstock composition for petrochemical-grade offtake tend to favour single-resin polyethylene-derived or polypropylene-derived PyOil, while buyers with more flexible downstream processing can accept mixed polyolefin PyOil at typically lower cost.
This four-category group together accounts for the majority of PyOil volume described in this report, reflecting how concentrated post-consumer and post-industrial waste streams are around polyethylene and polypropylene resin.
Polyethylene and polypropylene decompose across different temperature profiles during pyrolysis, so a feedstock blend skewed toward one resin over the other can shift the ideal operating conditions for a given technology configuration.
Buyers typically request a specification sheet covering density, sulphur content and chlorine content before accepting a PyOil delivery, since these properties determine how readily the batch integrates into an existing refinery or petrochemical process stream.

BUYER INSIGHT Buyers negotiating PyOil offtake increasingly specify resin composition tolerance bands rather than a bare PyOil type label, since two batches both labelled mixed polyolefin PyOil can still carry materially different polyethylene-to-polypropylene ratios that affect downstream cracker performance. |
Multi-layer plastic feedstock PyOil is recovered from packaging built from several bonded polymer and barrier layers, a category mechanical recycling generally cannot separate but chemical recycling can process as a combined feedstock.
Tire-derived pyrolysis oil is recovered from end-of-life tires rather than plastic waste, and is treated as a distinct PyOil type category in this report given its different feedstock chemistry, sulphur content and downstream handling requirements relative to plastic-derived categories.
Industrial polymer waste-derived oil covers pyrolysis oil recovered from off-specification resin, manufacturing scrap and other industrial polymer waste rather than post-consumer collection, typically offering more consistent composition than municipal mixed streams.
Tire-derived pyrolysis oil is the fastest-growing PyOil type category in this report, tracking expanding tire pyrolysis capacity investment alongside plastics-focused capacity across both regions.
Multi-layer plastic feedstock PyOil addresses a genuine gap left open by mechanical recycling, since multi-material packaging that cannot be mechanically separated into single-resin streams has historically gone to landfill or incineration rather than any recycling route.
Multi-layer films that include PVC or other chlorine-bearing layers require pre-sorting before pyrolysis, since chlorine contamination in the feedstock carries through into the PyOil product and can corrode downstream processing equipment.
Tire-derived pyrolysis oil carries materially higher sulphur and aromatic content than plastic-derived PyOil, a compositional difference that keeps it on a distinct downstream handling and certification path rather than being blended interchangeably with plastic-derived categories.
Post-consumer plastic waste is the largest feedstock source category described in this report, covering household and commercial waste collected after end use.
Post-industrial plastic waste covers manufacturing scrap, off-cuts and rejected material generated before a product ever reaches a consumer, typically offering more consistent composition and lower contamination than post-consumer streams.
Packaging film waste sits between these two categories in practice, since flexible film packaging is collected through both post-consumer household schemes and post-industrial converter scrap streams depending on the collection network involved.
Feedstock source selection connects directly to the pyrolysis technologies each feedstock stream suits, since a consistent post-industrial stream can often run through a simpler technology configuration than a variable post-consumer stream requiring more active process control.
Post-consumer plastic waste collection networks are considerably more developed in parts of Europe than in most of North America, a gap several waste aggregation partnerships covered on the customer and go-to-market page are specifically structured to close.
Post-consumer streams generally carry higher moisture content and more variable contamination than post-industrial scrap, since post-industrial material has not been through a household collection and washing cycle at all.
Packaging film waste destined for food-contact PyOil applications must be handled and documented separately from non-food-contact film waste from the point of collection onward, since blending the two streams would compromise food-contact compliant certification further down the value chain.
Some producers blend post-consumer and post-industrial streams deliberately, using the more consistent post-industrial fraction to stabilise overall feedstock quality when post-consumer supply volume or composition fluctuates seasonally.
Flexible plastic waste covers films, pouches and other non-rigid packaging formats that mechanical recycling struggles to sort and process economically at scale.
Agricultural plastic waste covers greenhouse film, mulch film and other farm-use plastic, a feedstock source concentrated in specific rural collection geographies rather than distributed evenly across a country.
Automotive plastic scrap covers end-of-life vehicle plastic components, typically collected through dismantler and shredder networks rather than municipal waste streams.
Municipal mixed plastic streams cover the residual mixed plastic fraction remaining after recyclable single-resin material has already been sorted out of municipal collection, historically the hardest-to-place fraction of household plastic waste.
Certification readiness for each of these feedstock streams connects closely to the certification schemes each feedstock stream supports, since traceability documentation is considerably more straightforward for a single-source agricultural or automotive stream than for a blended municipal mixed plastic stream.
Flexible plastic waste and multi-layer plastic feedstock together form the fastest-growing feedstock category in this report, tracking the wider industry shift toward processing streams mechanical recycling cannot economically serve.
Agricultural plastic waste often carries soil, moisture and organic residue that requires additional pre-treatment before pyrolysis, a handling step most other feedstock sources in this report do not require to the same degree.
Automotive plastic scrap frequently arrives mixed with foams, elastomers and other non-plastic materials from the dismantling process, requiring more intensive sorting than a comparatively clean packaging film waste stream before it can be processed consistently.
Municipal mixed plastic streams typically arrive with the widest composition variability of any feedstock source in this report, which is one reason producers processing this stream tend to favour technology configurations built for feedstock flexibility over high single-batch yield.
This report tracks seven PyOil type categories: plastic-derived, mixed polyolefin, polyethylene-derived and polypropylene-derived PyOil, multi-layer plastic feedstock PyOil, tire-derived pyrolysis oil and industrial polymer waste-derived oil.
Tire-derived pyrolysis oil is PyOil recovered from end-of-life tires rather than plastic waste, treated as a distinct category given its different feedstock chemistry and handling requirements.
Feedstock purity, whether a waste stream is single-polymer or a mixed, multi-layer blend, determines which PyOil type categories are achievable before technology configuration is even considered.
Multi-layer plastic feedstock PyOil is recovered from packaging built from several bonded polymer and barrier layers, a feedstock mechanical recycling generally cannot separate but chemical recycling can process as a combined stream.
This report tracks seven feedstock source categories: post-consumer plastic waste, post-industrial plastic waste, packaging film waste, flexible plastic waste, agricultural plastic waste, automotive plastic scrap and municipal mixed plastic streams.
