Small Pyrolysis Machine: 8-10t/Batch Plastic Bale Processing Capacity

Plastic pollution has reached critical levels, with around 400 million tons of plastic waste generated globally each year. Yet, less than 10% of this waste is recycled. Traditional recycling methods struggle with contaminated or mixed plastics, leading to increased interest in pyrolysis technology as an effective alternative. However, large-scale pyrolysis plants are costly and complex, with multi-million dollar investments and operational challenges. This is where small pyrolysis machines—capable of processing 8-10 tons per batch—offer a transformative solution for democratizing plastic waste recycling.

Industrial-scale pyrolysis plants require significant investments (ranging from $5 million to $20 million) and large-scale feedstock supply, which can be difficult to secure with mixed plastic waste. Additionally, long permitting processes limit participation to major operators. In contrast, small pyrolysis machines have much lower upfront costs (ranging from $150,000 to $500,000), are modular, and can be deployed in diverse settings, including municipal waste sites and remote locations with limited infrastructure.

Small pyrolysis machine offer an efficient, straightforward process. After shredding plastic bales, feedstock is prepared, with moisture content ideally below 15% for maximum efficiency. The material is then heated in an oxygen-free environment at temperatures between 400-500°C, breaking it down into gas, oil, and carbon black. The process yields about 70-80% oil, 15-20% gas, and 5-10% char. The gas is condensed into liquid fuel resembling diesel, while any non-condensable gas is recycled to sustain the system's heat. The oil can be refined or sold as-is, carbon black used in industries like tire manufacturing, and syngas powers the reactor itself.

Small pyrolysis machines present strong economic potential. For example, an 8-ton batch machine costs between $200,000 and $400,000 and processes a batch in 8-12 hours. With a daily capacity of 16-20 tons, the unit can produce 5-6 tons of pyrolysis oil per day, generating monthly revenues of $60,000-$100,000 at current oil prices ($400-$600 per ton). The investment can typically be recouped in 12-24 months, depending on factors like feedstock costs and potential government incentives, such as carbon credits or waste management subsidies.

The future for small pyrolysis machines looks promising, especially in regions with strict waste management regulations like Europe and Asia. Startups such as Plastic Energy and Agilyx have secured substantial funding, highlighting the potential of this technology. Moreover, pyrolysis's ability to sequester carbon from plastic waste positions it well within the growing carbon credit markets.

While small pyrolysis machines may not replace large-scale operations entirely, they provide an essential solution to expand plastic waste recycling access. Offering a cost-effective, flexible, and scalable option, these units bridge the gap where large-scale infrastructure is impractical. For waste processors, recyclers, and investors, small pyrolysis presents a powerful, tangible approach to tackling the global plastic crisis. The technology is already here—widespread implementation is the next step. Are we ready to embrace this opportunity?
