Continuous plastic project qualification

Qualify the feed and operating campaign before selecting the line

A continuous plastic pyrolysis plant is an integrated project, not a reactor selected from a daily tonnage alone. Define the incoming waste, preparation system, operating campaign, downstream products and site acceptance basis before equipment is sized.

Primary equipment page

One material-specific destination for continuous plastic projects

Use this page for a continuous line built around waste plastic. The continuous equipment hub remains the family overview, while the batch plastic page covers a separate cycle-based operating route.

Four decisions that control the configuration

Each decision should connect a buyer input to a supplier document or test. Generic model labels are not enough for contract comparison.

01

Define the feed

Record source, polymer mix, physical form, contamination, moisture and delivery variation. The proposal should state the accepted feed window and the sampling or test basis used to set it.

02

Draw the complete line boundary

Assign responsibility for sorting, size reduction, buffering, sealed feeding, thermal conversion, condensation, non-condensable gas, solids and residue handling—not only the reactor.

03

Set output destinations first

State the intended oil or condensate use and the route for solids and residues. The supplier should connect equipment choices to a project mass balance and written product or disposal criteria.

04

Write the site acceptance basis

Define utilities, plot interfaces, permits, emissions controls, safety responsibilities and maintenance access, then agree how a stable run, throughput and output quality will be measured.

Minimum input pack for a comparable RFQ

Send the same evidence to every supplier so configuration, scope and exclusions can be compared on one basis.

  1. 01Annual source, quantity and delivery-variability record
  2. 02Representative samples and available composition or contaminant tests
  3. 03Current sorting, size-reduction, storage and feed-handling plan
  4. 04Operating calendar, planned stops and maintenance resources
  5. 05Site layout, utilities, fire protection and permit constraints
  6. 06Required output destinations and contract acceptance method

Request a configuration review with evidence, not a generic model quote

Share the material record, operating basis and site interfaces. Pyrojin can then define the equipment boundary, open assumptions and tests that must be closed before contract.

Day 37 feedstock screening matrix

Screen polymer families before continuous-line design

This matrix is an early project screen for representative samples, not a list of guaranteed acceptable feeds. Polymer family, additives, contamination, physical form and the required product route must be assessed together.

Polymer streamScreening positionWhy the boundary mattersEvidence and pre-treatment to close
PEHDPE and LDPE streamsCandidate after testingPolyethylene is a hydrocarbon-rich polyolefin, but film, rigid parts, fillers, labels and contamination can change feeding, heat transfer and products.Report PE share, grade and form; test moisture, ash, halogens and metals; define sorting, cleaning, size reduction, blending and feeding trials.
PPRigid PP, woven or film streamsCandidate after testingPolypropylene is also a polyolefin candidate, while fillers, pigments, glass fibre and mixed closures can alter residue, gas and condensate behaviour.Quantify PP and non-PP fractions, additives and inerts; submit representative samples; confirm preparation, feedability and the intended condensate route.
PSRigid or expanded polystyreneConditional — product route firstPolystyrene can produce an aromatic and styrene-rich condensate profile that differs from polyolefin-derived oil. Expanded material also changes bulk-density and feeding design.Separate the PS stream where practical; declare rigid or foam form, additives and flame retardants; agree the product specification and condensation route before sizing.
Mixed plasticsVariable post-consumer or industrial mixConditional — composition controls designA mixed label does not define polymer ratios, PVC/PET carryover, brominated additives, food residue, paper, metals or delivery variation.Provide a seasonal composition study and composite samples; sort incompatible fractions, remove metals/inerts, wash or dry where required, then homogenise and buffer the prepared feed.
PETBottles, sheet and polyester-rich fractionsSeparate or specialist routePET contains oxygen and can form oxygenated or acidic products, gas and solids that create a different product and condensation basis from PE/PP.Do not treat PET as interchangeable with polyolefins. Quantify carryover, assess a separate recycling route, or obtain a written specialist process and product-acceptance basis.
PVC and halogenated plasticsPVC, chlorinated items and halogen-bearing additivesExclude until specifically engineeredPVC can release hydrogen chloride and chlorinated species, creating corrosion, emissions, catalyst and downstream product risks. Resin labels alone do not cover all halogen sources.Segregate from the standard feed; test total chlorine and other halogens; only proceed with a documented dehalogenation, materials, gas-cleaning, emissions and product-acceptance package.
Contract control gates

Moisture and chlorine need measured project windows

Write the test basis and response action next to each acceptance limit. A number without sampling, method and disposition rules is not an engineering control.

Moisture and free water

State whether results are as-received or dry basis, capture delivery variation and distinguish surface water from the polymer stream. Moisture affects drying duty, stable feeding and water handling.

Buyer supplies composite-sample results; supplier states the accepted window, dryer duty, water handling and reject or diversion rule.

Chlorine and other halogens

Measure representative feed rather than estimating from visible PVC alone. Link feed halogens to HCl capture, material selection, gas cleaning and oil/solid destinations.

Agree the analytical method, feed window, product specification, monitoring point and stop or diversion rule before contract.
Prepared-feed workflow

Convert an incoming waste description into a controlled feed lot

The final sequence depends on the waste stream and reactor interface, but every proposal should show where these controls sit and who owns them.

  1. 01Map source, seasonality and packaging or collection changes.
  2. 02Take representative composite samples and retain reference material.
  3. 03Identify polymer shares, additives, halogens, moisture, ash, metals and other inerts.
  4. 04Sort incompatible fractions and remove metals, fines and foreign materials.
  5. 05Wash, dewater, dry and reduce size where the verified feed specification requires it.
  6. 06Blend and buffer prepared lots; record traceability and release each lot against the agreed window.
Day 38 engineering-claim review

Evidence review complete; project engineering release still required

The five statements below have been checked as conditional design language against government, standards-body and peer-reviewed sources. They do not certify a named plant, feed batch, product, permit or operating procedure.

Desk-review statusSource-backed wording retained
Project release statusPending named-model and site sign-off
01Boundary retained

Feedstock applicability

The Day 37 PE, PP, PS, mixed-plastic, PET and chlorinated-plastic matrix is suitable only for early screening. Resin names do not close variability, additives, physical form, moisture, ash, metals or halogens.

Release evidence
Approve a feed window only from representative composite samples, stated test methods, delivery variation and a feeding or process trial tied to the selected line.
02Destination-specific

Oil and condensate destination

Plastic pyrolysis liquid is an intermediate stream whose properties depend on feed and operation. It is not automatically accepted as a finished fuel, refinery feed or steam-cracker feedstock.

Release evidence
Name the receiver and specification, then agree sampling and analysis for water, solids, halogens, acidity, heteroatoms, metals, boiling behaviour and stability as required by that destination.
03Conditional reuse

Non-condensable gas loop

Recovered gas may contribute process heat, but quantity, composition and heating value vary. Recycle must not be presented as guaranteed energy self-sufficiency or as a substitute for a safe start-up and upset strategy.

Release evidence
Issue gas composition and heating-value data plus the cleaning basis for acid gases, water, tar and particles, with pressure control, isolation, purge, flame supervision, trips, safe disposal or backup-fuel logic and the approved sequence.
04No automatic product status

Solids and residues

Char, fines, salts, spent sorbent and separated contamination remain distinct streams. Plastic-derived solid is not recovered carbon black or a saleable product merely because it contains carbon.

Release evidence
Characterise carbon and ash, halogens, metals, PAHs or other residual organics, leaching and hazard properties, plus self-heating and combustible-dust risks; document cooling, storage, transport and an authorised route.
05Site-specific safety case

Safety and emissions

Oxygen exclusion alone does not resolve fire, explosion, overpressure, corrosive gas, hot-solid, liquid-storage or combustion hazards. Emissions performance depends on the complete line and the applicable permit.

Release evidence
Close the P&IDs, hazard study, relief and safe-disposal basis, hazardous-area review, gas detection, burner management, alarms, interlocks, emergency shutdown, fire protection, emissions monitoring and pre-start-up review.
Engineering release pack

Seven documents before a project claim becomes a guarantee

Each document needs a revision, named owner and approval status. A brochure sentence or equipment list cannot replace this record.

  1. 01Approved feed specification, sampling plan and representative laboratory results.
  2. 02Process flow diagram, P&IDs, equipment boundary and project mass-and-energy balance.
  3. 03Liquid, gas and solid stream specifications with named destinations and receiver acceptance.
  4. 04Gas-handling diagram and cause-and-effect for purge, ignition, flame failure, pressure and emergency shutdown.
  5. 05Residue sampling, classification, cooling, self-heating and dust controls, storage, transport and disposition plan.
  6. 06Project hazard and pre-start-up review covering relief, vents, hazardous areas, fire/explosion protection and operating procedures.
  7. 07Local permit matrix, emissions-control and monitoring plan, plus written site-acceptance criteria.
Waste plastic pyrolysis equipment

Configure a continuous waste plastic pyrolysis line

Plastic pyrolysis performance varies widely by polymer mix, contamination, chlorine content, moisture and preparation. A continuous plastic pyrolysis plant should therefore be configured from representative feed testing and the required downstream oil specification.
