A successful plastic to oil project starts with feedstock control. Not every plastic behaves the same during pyrolysis, and mixed waste can significantly change oil yield, wax formation, gas composition, corrosion risk, and residue volume.
Before selecting a plastic recycling pyrolysis plant, you need to know which polymers dominate your feedstock, how much moisture and contamination are present, and what you plan to do with the recovered oil. These factors determine whether your project needs sorting, drying, shredding, dewaxing, enhanced condensation, or additional gas treatment.
Which Plastics Are Better Suited for Oil Recovery?
PE Offers High Oil Recovery Potential
Polyethylene (PE) is widely found in plastic film, shopping bags, agricultural film, shrink film, HDPE containers, bottles, and pipes.
Relatively clean PE can provide an indicative oil yield of around 80–95%. However, PE-rich feedstock, especially film waste, tends to generate heavier wax fractions.
For this type of plastic pyrolysis recovery project, Yushunxin can configure larger oil-gas passages, dewaxing equipment, and suitable condensation systems to reduce wax accumulation and cleaning frequency.
PP Performs Well in Plastic-to-Oil Projects
Polypropylene (PP) commonly comes from woven bags, bottle caps, plastic buckets, food containers, storage boxes, trays, and injection-molded products.
Sorted PP can provide an indicative oil yield of around 75–90%. If your feedstock contains fillers, dirt, labels, or non-plastic materials, the actual liquid recovery will be lower.
For PP-dominated plastic to oil projects, Yushunxin can match the feeding, reactor, condensation, and oil collection system to your actual material condition and required processing capacity.
PS Produces a High Liquid Fraction
Polystyrene (PS) can be found in EPS packaging foam, insulation foam, protective packaging, disposable food containers, and other rigid PS products.
Clean PS may produce approximately 80–92% liquid product. Its oil is generally more aromatic than PE- or PP-derived pyrolysis oil.
If PS represents a large percentage of your feedstock, you should confirm the downstream oil application before finalizing your plastic recycling pyrolysis plant configuration.
ABS Can Also Be Processed by Pyrolysis
ABS is commonly used in appliance housings, electronic equipment housings, automotive trim, luggage, toys, and other engineering-plastic products.
Its indicative oil yield is around 40–50%. Because ABS contains acrylonitrile, butadiene, and styrene, its gas and liquid products differ from those produced from PE or PP.
Yushunxin can adjust the condensation and gas-treatment configuration when ABS forms a significant part of your feedstock.
Are Paper Mill Rejects Suitable for Plastic Pyrolysis?
Paper mill rejects should be treated as a mixed industrial waste stream, not as one specific polymer.
They may contain PE or PP film together with paper fibers, labels, adhesives, moisture, metals, and other impurities. Depending on composition and dryness, the indicative oil yield may vary widely, around 15–60%.
For this type of feedstock, Yushunxin can first evaluate the plastic content, moisture, impurities, and polymer composition before recommending sorting, drying, shredding, or other pretreatment equipment.
Which Plastics Should Be Removed First?
PVC Requires Priority Control
PVC can release chlorine-containing compounds during pyrolysis. This may increase equipment corrosion, affect pyrolysis oil quality, and place additional load on the gas-cleaning system.
PVC pipes, flooring, cable insulation, synthetic leather, and other chlorinated plastics should therefore be identified and controlled before feeding.
PET Is Less Suitable for Oil Recovery
PET generally produces much less useful liquid fuel than PE, PP, or PS and may generate more oxygenated and acidic products.
If PET represents a significant proportion of your waste stream, separating it can improve feedstock consistency and overall plastic pyrolysis recovery performance.
Before requesting a proposal, confirm your PE, PP, PS, and ABS proportions, PVC and PET content, moisture, impurities, feedstock size, daily supply, and target oil application.
Based on these conditions, Yushunxin can configure the pretreatment, feeding, pyrolysis, dewaxing, condensation, gas purification, and residue-handling systems around your actual feedstock instead of applying one standard solution to every plastic recycling project.
