High-efficiency continuous operating models engineered for maximum throughput, low energy consumption, and high oil yields.
As the Kathmandu Valley faces growing municipal solid waste management challenges alongside a sharp surge in end-of-life tires (ELTs) driven by rapid urbanization, conventional batch pyrolysis plants are quickly becoming obsolete due to high labor costs, inefficient thermal usage, and stringently enforced environmental monitoring by the Department of Environment (MoFE Nepal).
Our Continuous Waste Tire Pyrolysis Plant featuring the advanced Drum Running Model introduces a paradigm shift. Unlike stationary reactors equipped with internal screw conveyors that suffer from rapid mechanical fatigue, coke accumulation, and uneven heating, the 360-degree rotating drum design guarantees continuous material tumbling, uniform heat transfer via indirect thermal radiant walls, and fully dynamic seal integrity.
Tailored engineering solutions addressing Nepal's terrain, climate factors, fuel deficits, and circular economy goals.
Kathmandu generates hundreds of tons of municipal solid waste daily, with waste tires piling up along major arteries like Ring Road and industrial centers in Patan, Balaju, and Bhaktapur. Continuous drum pyrolysis diverts rubber scrap from overburdened dumpsites like Banchare Danda, converting waste into revenue-generating resources.
Nepal's industrial sector relies heavily on imported liquid fuels. The Pyrolysis Oil (Tire Pyrolysis Oil - TPO) produced by our continuous plants features a high calorific value (42-44 MJ/kg), offering an immediate, cost-effective heavy oil substitute for local brick kilns, asphalt mixing plants, and industrial boilers within the valley.
The solid residue recovered from drum continuous processing yields high-purity carbon black. Local Nepalese rubber product manufacturers, cement factories (for co-processing/fuel), and asphalt compounding facilities provide an eager local market for refined rCB powder.
Overcoming high-altitude thermal loss and continuous material sealing obstacles in Kathmandu.
Operating continuous plants in the Kathmandu atmospheric zone (approx. 1,400 meters altitude) requires dynamic pressure adjustments. Lower ambient pressure affects gas flow dynamics. Our drum running system integrates automated negative-pressure draft control, preventing gas escape and guaranteeing steady gas evacuation into multi-stage vertical condensers.

Focusing on waste-to-energy and waste tire pyrolysis technology, Huayuan Tech was founded in 1968. The company covers an expanse of 209,335 square meters, with a modern industrial manufacturing plant area of 98,680 square meters and over 500 skilled employees—engineering and technical research personnel accounting for more than 34% of our workforce.
Huayuan Tech holds a national A-class boiler manufacturing license, A2-class pressure vessel manufacturing license, and D1/D2 pressure vessel design certificates. We maintain full ISO9001, ISO14001, and OHSAS18001 system certifications alongside prestigious United States ASME authorization stamps.
Initially, Huayuan Technology pioneered boiler heat exchanger technology across specialized workshop facilities.
Evolved into Linyi County Boiler Manufacturing Factory and subsequently restructured into Linyi Boiler Co., Ltd., expanding manufacturing capability for pressure vessels.
Obtained national A-level boiler manufacturing licenses, ISO triple system certification, and initiated production of early-generation batch waste tire pyrolysis machines.
Relocated to a 220-acre modern facility in Zaoyuan Industrial Park. Successfully engineered continuous screw and continuous drum-running model pyrolysis plants, obtaining U.S. ASME accreditation.
Adhering to our vision of "Energy Conservation & Emission Reduction: Making the sky bluer, the earth greener, and the water cleaner," expanding our tailored export engineering directly to key emerging regional hubs like Kathmandu, Nepal.
Streamlined manufacturing efficiency combined with specialized cross-border logistical support for Nepal.
Utilizing high-tensile Q345R pressure vessel steel, automated submerged arc welding, and non-destructive ultrasonic flaw detection, our Chinese mega-factory guarantees structural integrity designed to endure decades of thermal stress cycles.
We manage complex multimodal shipping routes into Nepal via Gyirong Port (Rasuwagadhi border crossing) or Kolkata port transit corridors. Machinery is custom-modularized to fit standard flat-rack and high-cube containers, overcoming narrow Himalayan highway constraints.
Our experienced field engineers deploy directly to installation sites in Kathmandu Valley. We handle plant assembly, system debugging, safety valve calibration, and localized operator training in Nepali or English.
