In September 2026, DOING ECO's 2.5TPD fully continuous plastic to diesel and gasoline integrated plant entered installation and trial run at the customer's site in Indonesia.
The customer is an Indonesian automotive parts manufacturer. DOING ECO's engineers are on site to provide installation, commissioning and technical support.
Unlike ordinary plastic pyrolysis projects, this customer needed two different fuel products—gasoline and diesel—for oil coating protection of finished vehicle parts. To meet this requirement, DOING ECO supplied an integrated system combining continuous pyrolysis, catalytic cracking and fractionation
Project Details
Item | Details |
Customer | Automotive parts manufacturer in Indonesia |
Plant | 2.5TPD fully continuous plastic to diesel and gasoline integrated plant |
Signed | June 2026 |
Shipped | July 2026, by sea |
Application | Gasoline and diesel for oil coating protection of vehicle parts |
Status | Installation and trial run, September 2026 |
The customer previously purchased gasoline and diesel from external suppliers. This created ongoing fuel costs, while the quality and purity of purchased fuels were not fully under the customer's control.
By producing the required fuels in-house, the customer aims to address both issues and better control the fuel used in its manufacturing process.

Why One Fuel Was Not Enough
Before selecting the equipment, the customer had inspected batch pyrolysis plants operating at other factories in Indonesia.
These conventional systems mainly produce mixed pyrolysis fuel oil. To obtain separate gasoline and diesel products, an additional distillation process is required. Moreover, fuel oil quality can vary between batches.
For the customer's automotive parts coating application, a single mixed fuel oil was not the ideal solution. The customer needed two separate fuel fractions with more consistent production conditions.
Therefore, DOING ECO designed an integrated system that combines pyrolysis, catalytic cracking and fractionation in one production line.
Plant Configuration: Module by Module
Module | What it does |
Continuous pyrolysis reactor with sealed screw feeder | Feeds shredded plastic without air ingress and runs without stopping; heavy-duty drive gears, roller supports and high-temperature seals keep the turning reactor tight |
Catalytic cracking tower and fractionating column | Split the pyrolysis vapours into gasoline and diesel fractions inside the same line, so no separate distillation plant is needed |
Condensation train | Shell-and-tube condensers turn the separated vapours into liquid gasoline and diesel, with oil pumps and circulating water pumps keeping the liquids moving |
PLC control cabinet | Runs feeding, temperatures, discharge and safety interlocks from one panel, with multi-point thermocouples, pressure transducers and automated valves |
Gas recycling and flue gas purification | Non-condensable gas returns through a water seal to the burners, and a dedusting and deodorizing scrubber keeps emissions within Indonesian standards |
Before shipment, all welded parts of the plant passed pneumatic pressure tests at the factory. This helped verify the pressure boundaries before the equipment was transported to Indonesia.

How Does One Production Line Produce Two Fuel Products?
The production process starts when shredded plastic is fed into the reactor through a sealed screw feeder.
The reactor continuously heats and processes the plastic, generating vapours that pass through the catalytic cracking tower and fractionating column.
During fractionation, the vapours are separated according to their boiling characteristics:
Light fractions: Condensed into gasoline.
Heavier fractions: Condensed into diesel.
The condensation system then collects the two liquid fuel products separately.
Meanwhile, carbon black is discharged through a water-cooled screw conveyor without interrupting continuous production. The PLC control system manages feeding, temperature, discharge and safety interlocks.
Installation and Commissioning Service
DOING ECO's engineers are providing on-site installation and commissioning services for the 2.5TPD integrated plant.
The work includes:
Positioning equipment according to the plant layout drawing.
Connecting pipelines and electrical wiring.
Calibrating burners and checking individual systems.
Commissioning the production line.
Training the customer's operators.
Specialized assembly tools, spare gaskets and replacement seals were also shipped with the equipment.
During operator training, the engineers cover feed rate management, temperature adjustment and routine preventive maintenance. The goal is to enable the customer's own team to operate and maintain the production line independently.

Trial Run in Progress
Trial feeding of the 2.5TPD fully continuous plastic to diesel and gasoline integrated plant has started.
During this stage, DOING ECO's engineers are monitoring the temperature profile along the reactor, the sealing conditions at the feeding and discharging ends, and the separation performance of the fractionating column.
The gasoline and diesel fractions need to remain stable before the production line is handed over to the customer's team.
FAQ
1. Does 2.5TPD refer to the oil output?
No. 2.5TPD refers to the daily waste plastic processing capacity, not the final oil output. Part of the feedstock becomes carbon black, non-condensable gas and moisture, so the liquid fuel output is lower than the feedstock input.
2. Which types of plastic can be processed?
Common waste plastics with good oil yield, such as PE, PP and PS, are suitable for this design. Feedstock containing a high proportion of PVC is not recommended.
3. How long did production take before shipment?
The factory production period was 35 days. The equipment was shipped by sea to Indonesia in July 2026.
