New Zealand produces over 5 million end-of-life tyres (ELT) annually. With the 2024 launch of Tyrewise, the country's first regulated product stewardship scheme, the demand for local Continuous Waste Tire Pyrolysis Plant technology has surged. Our screw running models are designed to meet the strict environmental standards set by the NZ Ministry for the Environment.
Unlike batch systems, the Screw running model offers a continuous feeding and discharging mechanism. This is critical for New Zealand’s medium-to-large scale industrial operations in regions like Auckland, Christchurch, and Waikato, where efficiency and minimal downtime are paramount for commercial viability.
The NZ government's commitment to a circular economy means moving away from stockpiling tires. Our plants convert waste into high-value Tire Pyrolysis Oil (TPO) and recovered carbon black, which are increasingly sought after by the New Zealand roading and maritime fuel sectors.
Focus on waste to energy and waste tire pyrolysis technology, Huayuan Tech was founded in 1968. Company covers an area of 209,335 square meters, plant area of 98,680 square meters, more than 500 employees, engineering and technical personnel accounting for 34% of the total number of employees. Has a complete A-class boilers and pressure vessels complete sets of manufacturing, testing equipment.
With the continuous development of enterprises has now become engaged in a boiler, pressure vessels, waste tire and plastic scrap pyrolysis machine development, manufacturing, sales, consulting services, thermal equipment system integration, contract energy management, investment and financing, supplemented by energy efficient use of professional firms. Holding a national A-class boilers, A2-class pressure vessel manufacturing license, D1D2 pressure vessel design certificate.
Pressure pipe installation permit, and through iSO9001, ISO14001, OHSAS18001 three system certification and the United States ASME certification. For New Zealand clients, this means every Continuous Waste Tire Pyrolysis Plant we export meets the highest safety and durability standards required for local Resource Consent applications.
Integrating screw pyrolysis units into waste management facilities in South Auckland to process urban tire waste into industrial heating oil for local manufacturing.
Utilizing recovered carbon black from tires in the production of high-durability rubber components for the forestry industry and logistics fleets operating in the Southern Alps regions.
Refining pyrolysis oil to serve as a sustainable fuel blend for New Zealand’s coastal shipping vessels, reducing reliance on imported heavy fuel oils.
The Continuous Waste Tire Pyrolysis Plant (Screw running model) is specifically engineered to handle the throughput requirements of modern New Zealand waste plants. Unlike older technologies, this model ensures:
Our screw running model utilizes a high-temperature, anaerobic thermal decomposition process. The specialized screw design ensures that tire shreds or rubber powder are moved through the reactor at a precise speed, ensuring uniform heating and maximum oil yield. This technology is particularly effective for New Zealand's varied tire types, including passenger car tires and heavy OTR (Off-The-Road) tires used in NZ’s mining and agricultural sectors.
As New Zealand moves towards its 2050 net-zero goal, the role of advanced pyrolysis technology is evolving. The NZ Emissions Trading Scheme (ETS) is increasingly looking at waste-to-energy projects. By diverting tires from landfills and producing renewable fuels, NZ enterprises can potentially leverage carbon credits. Furthermore, the push for "Green Roads" by Waka Kotahi (NZ Transport Agency) is creating a massive market for recovered carbon black and tire-derived aggregates.
Huayuan Tech remains at the forefront of this transition, providing not just machinery, but complete system integration including Waste Heat Boilers and Oil Refining Plants to ensure NZ manufacturers can produce high-grade diesel-like fuel locally.
