RFQ for Waste Recycling Pyrolysis Equipment: What to Include

A useful Request for Quotation (RFQ) for waste recycling pyrolysis equipment should make five things clear: what you want to process, how much you need to process, how the system should operate, where it will be installed, and what the supplier should include in the quotation.

Based on Doing ECO’s experience delivering pyrolysis production lines to clients across 120+ countries and regions, the key information can be grouped into five areas: project background, feedstock, capacity and process, technical and compliance requirements, and commercial scope.

Necessary elements included in a quotation for waste pyrolysis equipment

You do not need to specify every engineering parameter yourself. If a requirement depends on the feedstock or process, ask the supplier to recommend a suitable configuration.

Pyrolysis Equipment RFQ Checklist

1. What Project Information Should Be Included?

Start with the basic project information:

• Destination country and city

• Delivery port or final delivery address

• Target commissioning date

• Expected operating schedule

• Budget range, if available

The destination is important because it can affect shipping, local standards, installation, import procedures, and the Incoterm used in the quotation.

A final budget is not essential, but an approximate investment range can help suppliers avoid proposing equipment that is significantly larger or more complex than required.

Key project details for an accurate pyrolysis equipment quotation

For example, Doing ECO uses the destination and budget information to determine whether to propose a standard configuration or a customized solution, and to calculate accurate shipping costs based on the nearest port of discharge.

2. What Feedstock Information Does the Supplier Need?

Feedstock is one of the most important parts of an RFQ. Different wastes can require different pretreatment, feeding, heating, condensation, and residue-handling systems.

Include:

• Feedstock type

• Physical form and particle size

• Moisture content

• Contamination level

• Main composition, if known

• Whether pretreatment is required

• Approximate daily feedstock availability

Be as specific as possible rather than simply writing “waste” or “mixed waste.”

Key feedstock details needed for a pyrolysis equipment quotation

For example:

• A tire recycling pyrolysis project should indicate whether the feedstock consists mainly of passenger car, truck, or OTR tires.

• A plastic project should identify the main polymer types, such as PE, PP, or PS.

• If several feedstocks may be processed, list them separately.

Doing ECO’s engineering team uses this information to recommend specific pretreatment configurations. For example, waste tires require bead wire removal and shredding to 5–20 mm before feeding to a continuous pyrolysis reactor, while mixed plastics may need crushing and drying.

Pyrolysis pretreatment process for different types of waste

DOING pyrolysis systems have processed over 30 types of feedstock, including waste tires, mixed plastics, oil sludge, medical waste, and aluminum-plastic composites, with each requiring a different reactor configuration and temperature profile.

3. How Should Capacity and Process Type Be Specified?

State the required capacity clearly and use the correct unit:

• kg/day for laboratory or pilot systems, typically 100–500 kg/day

• tons/day (TPD) for commercial systems, typically 15–50 TPD per set

• tons/batch for batch equipment

Do not confuse batch capacity with continuous throughput.

Because “semi-continuous” can mean different things between suppliers, ask them to explain how feeding, heating, pyrolysis, and discharge actually operate.

For example, if you require 20 TPD continuous processing, write “20 TPD continuous throughput” rather than simply “20-ton pyrolysis plant.”

4. What Technical Requirements Should Be Included?

An RFQ should describe the required performance without requiring the buyer to design the equipment.

Product and Process Requirements

State the products you expect, such as:

• Pyrolysis oil: target oil yield and intended application

• Recovered carbon black: whether you want to refine it for further application or meet a specific refining degree

• Steel wire

• Syngas

Applications of products from waste tire pyrolysis and oil recovery projects

If product quality is important for your market, include the relevant requirements where known.

You can also specify requirements for:

• Feeding and discharge

• Heating method

• Syngas recycling

• Condensation and oil collection

• Residue handling

• Flue-gas treatment

• Product upgrading

• PLC/HMI or other automation

Waste pyrolysis oil refining environmental protection equipment configuration

If you do not have an established engineering specification, it is usually better to ask:

“Supplier to recommend a suitable configuration based on the feedstock, capacity, and operating requirements.”

This allows the supplier to propose pyrolysis equipment based on the actual project rather than forcing the buyer to define technical parameters they may not be familiar with.

Compliance Requirements

State the standards and regulations applicable to the destination market, such as:

• CE or other applicable equipment requirements

• ATEX requirements where applicable

• Electrical and control-system standards

• Local emission requirements

• Environmental approval requirements

Do not assume that the same requirements apply in every country.

Doing ECO holds ISO 9001 and ISO 14001 management systems and CE marking for equipment exported to international markets. Its pressure vessel components are built based on EN 13445 standards.

When preparing a waste recycling equipment quotation, Doing ECO’s engineering team reviews the destination country’s specific regulatory requirements and adjusts the equipment configuration accordingly — for example, adding ATEX-compliant explosion-proof motors for installations in zones with combustible dust risk.

5. What Should Be Included in the Commercial Quotation?

Specify the commercial requirements that suppliers should include:

• Incoterm and destination

• Payment terms

• Delivery time

• Warranty

• Installation and commissioning

• Operator training

• Spare parts

• After-sales support

More importantly, ask the supplier to separate the quotation into clear cost categories, including:

• Base equipment

• Optional equipment

• Installation and commissioning

• Training

• Spare parts

• Transportation and other additional costs

Key cost items in a waste recycling pyrolysis equipment quotation

This makes supplier quotations easier to compare and prevents a low equipment price from appearing cheaper simply because important systems or services have been excluded.

Doing ECO provides a detailed scope breakdown in every waste recycling equipment quotation, clearly separating base equipment, installation and commissioning costs, operator training, spare parts packages, and transportation.

The standard delivery time for a complete pyrolysis line is 30–90 days from order confirmation, with 15–30 days allocated for on-site installation and commissioning. Warranty covers 12 months from the commissioning date, with lifetime technical support and spare parts supply.

6. What Evidence Should You Request From the Supplier?

An RFQ should not only ask “How much does the equipment cost?” It should also request information that allows you to evaluate the pyrolysis equipment supplier.

Ask for:

• Technical proposal with process flow diagram

• Equipment list and specifications

• Process flow diagram or layout

• Utility requirements, including power, water, and fuel consumption

• Expected output and yield basis

• Environmental treatment scope and emission data

• Similar project references

• Photos or videos of operating equipment

Case study of a continuous waste plastic pyrolysis equipment project

For pyrolysis project references, prioritize similarity in feedstock + capacity + process type, rather than simply choosing the supplier’s largest project.

For example, a 15 TPD oil sludge thermal pyrolysis project may be more relevant to another oil sludge project than a 50 TPD tire oil pyrolysis project, even though the latter has a larger capacity.
