Project Overview
In 2026, Shangqiu Jinpeng Industrial Co., Ltd. delivered and installed four sets of 15TPD batch-type waste tire pyrolysis plants for a waste tire recycling enterprise in Liaocheng, Shandong Province. The four-line configuration provides a combined processing capacity of approximately 60 tons of waste tires per day, converting scrap rubber into fuel oil, carbon black, steel wire, and combustible gas.
Shandong Province is one of China's most active regions for rubber processing and tire manufacturing, which also makes it a major generator of end-of-life tires. This project was designed to serve the local waste tire supply chain with a compliant, resource-recovery-oriented processing solution rather than low-value crushing or landfilling.
Why the Client Chose a 4 × 15TPD Batch Configuration
Rather than installing a single large-capacity reactor, the client opted for four independent 15TPD batch units. This decision was driven by several practical operational factors:
Staggered cycle scheduling - Each batch reactor runs its own loading, heating, pyrolysis, cooling, and discharge cycle. By staggering the four units, the plant maintains a steady daily output of oil and carbon black rather than experiencing large peaks and idle gaps.
Operational resilience - If one reactor requires maintenance or inspection, the remaining three units continue operating, preserving roughly 75% of plant throughput.
Lower initial investment threshold - A modular multi-line layout allows the client to scale capacity in stages as tire collection volumes increase.
Simplified maintenance access - Individual 15TPD reactors are easier to inspect, reline, and service than one oversized vessel.

Key system features delivered:
Horizontal rotary batch reactors with reinforced sealing doors and multi-layer insulation for stable thermal efficiency
Automatic feeding and discharge systems to reduce manual handling and shorten cycle turnaround time
Condensing and oil collection system for efficient recovery of pyrolysis oil from the oil-gas stream
Non-condensable gas recycling, with surplus combustible gas returned to the heating system to reduce external fuel consumption
Flue gas treatment system designed to meet applicable Chinese environmental discharge standards
Safety interlocks and pressure relief devices on each reactor to ensure safe operation throughout the batch cycle
From Waste Tires to Recovered Resources
A batch tire pyrolysis line processes waste tires in a sealed, oxygen-limited environment at controlled temperature. Typical recovered outputs from a waste tire feedstock include:
Pyrolysis fuel oil - used as industrial fuel, or further refined into diesel-grade products
Carbon black - applicable in rubber compounding, pigments, construction materials, or further processed into higher-grade carbon products
Steel wire - recovered after the pyrolysis cycle and sold directly to steel recyclers
Combustible gas - recirculated as process heating fuel, improving overall plant energy efficiency
This four-product recovery model is what makes tire pyrolysis economically attractive: nearly the entire input mass is converted into a saleable or reusable output stream.
Project Significance
The Liaocheng project demonstrates how a mid-scale, multi-line batch configuration can serve regional waste tire volumes efficiently. For enterprises collecting tires within a defined geographic radius, a 60TPD facility built from four modular units offers a practical balance between capital investment, operating flexibility, and resource recovery value.
For investors and operators evaluating similar projects, this case illustrates a repeatable model: start with a modular multi-line batch layout, match total capacity to reliable local feedstock supply, and expand line-by-line as collection volumes grow.
Frequently Asked Questions
What is a batch-type tire pyrolysis plant? A batch-type tire pyrolysis plant processes waste tires in discrete cycles. Each reactor is loaded with a fixed quantity of tires, sealed, and heated in an oxygen-limited environment to thermally decompose the rubber. After the cycle completes and the reactor cools, carbon black and steel wire are discharged and the reactor is reloaded for the next batch.
How much waste tire can a 15TPD unit process? Each 15TPD unit is designed to process approximately 15 tons of waste tires per 24-hour operating period. In the Liaocheng project, four such units provide a combined capacity of up to 60 tons per day.
What products are recovered from waste tire pyrolysis? The main outputs are pyrolysis fuel oil, carbon black, steel wire, and non-condensable combustible gas. Actual yields vary depending on tire type, moisture content, rubber composition, and operating parameters.
Why choose four 15TPD units instead of two 30TPD reactor? Multiple smaller batch reactors allow staggered operating cycles, easier maintenance, phased investment, and continued production when one unit is offline - advantages that a single large reactor cannot provide.
Can this configuration be applied outside China? Yes. The same 4 × 15TPD modular batch layout has been supplied to clients in multiple countries, with adjustments made for local feedstock characteristics, environmental regulations, and site conditions.
