Premium waste-to-energy and pyrolysis systems optimized for high throughput and environmental compliance.
As one of Central Africa's primary oil-producing nations, Equatorial Guinea—centered around the economic engines of Malabo (Bioko Island) and Bata (Río Muni mainland)—is facing a rapid transition. The expansion of oil refining, chemical processing, urban development, and agricultural processing has led to a significant accumulation of industrial solid waste, oily sludge, and end-of-life tires. Traditional disposal methods like open-air landfilling or unmitigated combustion are becoming ecologically unsustainable and regulatorily restricted.
Furthermore, the Government of Equatorial Guinea's national strategic frameworks, notably the Horizon 2035 agenda, prioritize industrial diversification, local energy sovereignty, and environmental stewardship. Implementing decentralized Industrial Solid Waste to Energy (WTE) plants offers a dual-benefit solution: it mitigates severe environmental contamination while generating valuable process steam, electricity, and synthetic oils, reducing the country's reliance on imported refined diesel for microgrids and industrial factories.
Our engineering framework is designed to convert high-calorific solid waste into clean thermal energy, combustible gas, and synthetic fuels.
Utilizes continuous screw and rotary kiln reactor geometries to thermally crack complex carbonaceous structures (waste tires, plastics, and petrochemical residues) in the absence of oxygen at temperatures ranging from 450°C to 750°C.
High-temperature exhaust gases from pyrolysis and thermal oxidizers are routed through multi-pass A-Class waste heat boilers, generating superheated steam that can drive turbine units or supply direct heat to refinery operations.
Integrated dry and wet scrubbers, combined with activated carbon adsorption and baghouses, neutralize acidic gases (SOx, NOx, HCl) and capture particulate matter, conforming strictly to EU 2010/75/EU emission levels.
Founded in 1968, Huayuan Tech has established itself as an international pioneer in thermal energy conservation, pressure vessel manufacturing, and industrial waste recycling systems. Spanning a vast footprint of 209,335 square meters (with a built-up plant area of 98,680 square meters), our company operates at the intersection of precision engineering and environmental technology.
Our team of over 500 dedicated employees includes engineering and technical specialists representing 34% of our workforce. This technical density enables us to maintain complete National A-class boiler manufacturing licensing, A2-class pressure vessel production credentials, and D1/D2 pressure vessel design certificates.
To guarantee absolute safety and performance for international markets like Equatorial Guinea, we are fully certified under the ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and OHSAS 18001 / ISO 45001 (Occupational Health & Safety) systems, alongside holding prestigious American Society of Mechanical Engineers (ASME) certifications.
Tracing our technological advancement from classic boiler fabrication to modern Industry 4.0 continuous pyrolysis plants.
Initially, Huayuan Technology developed boiler technology in several factory workshops, establishing fundamental thermo-mechanical capabilities.
Restructured as Linyi County Boiler Manufacturing and Repair Factory, under the jurisdiction of the Linyi County Industrial Bureau to scale production.
Renamed Linyi Boiler Factory and merged with Linyi Auto Parts Factory, relocating to a larger site at 373 Tongda Road.
Successfully restructured into Linyi Boiler Co., Ltd., transitioning into a streamlined corporate shareholding structure.
The successful restructuring provided wings for the company's takeoff and took the first step towards becoming a modern global enterprise.
Obtained national A-level boiler manufacturing license and ISO triple certifications. Commenced batch production of waste tire pyrolysis plants.
Moved to a state-of-the-art facility covering 220 acres in Zaoyuan Town Industrial Park. Launched focused R&D on continuous model pyrolysis systems.
Developed the screw running model continuous pyrolysis plant. Obtained American ASME certification, accelerating global distribution.
Unified operations under the green corporate vision: "doing energy conservation and emission reduction, making the sky bluer, the earth greener, and the water cleaner."
At Huayuan Tech, we combine heavy engineering capabilities with advanced automation systems. Our thermal recycling equipment integrates automatic loading systems, high-efficiency catalytic cracking structures, low-temperature condensation pathways, and electronic instrumentation control networks.
Watch our operations and test runs displaying the system integration of A-class boilers, pressure vessels, and polymer pyrolysis processing units. We offer customized thermal configuration, contract energy management, project financing consultancies, and engineering, procurement, and construction (EPC) solutions.
Why global enterprises buy from Huayuan Tech's intelligent factories.
Purchasing industrial equipment from Huayuan Tech leverages China's advanced manufacturing supply chain infrastructure. We utilize automated plasma cutting machines, heavy-duty plate rolling machines capable of handling up to 100mm thickness, submerged arc welding gantries, and 100% non-destructive testing (NDT) rooms. This robust tooling ensures structural reliability and minimizes mechanical deformation under thermal cycling.
Our localized raw material sourcing (high-grade Q345R pressure vessel steel, chromium-molybdenum heat-resistant alloys) and integration with domestic control component ecosystems allow us to supply complete waste-to-energy packages at highly competitive capital expenditures (CAPEX) compared to European manufacturers, without compromising on life expectancy or safety compliance.
Deploying heavy industrial machinery in locations like Bata or Malabo requires specific technical adaptions. We configure our plants to operate reliably under Equatorial Guinea's humid, tropical marine conditions, utilizing maritime-grade anti-corrosive coatings, stainless-steel electrical cabinets, and tropicalized IP65-rated wiring.
Furthermore, we support compliance processes with Equatorial Guinea's regulatory bodies, including the Ministry of Mines and Hydrocarbons and the Ministry of Agriculture, Livestock and Environment (MAEMA). Our documentation package includes full thermal calculation sheets, structural safety calculations, hazard and operability (HAZOP) studies, and complete P&ID drawings.
Upon cargo arrival at Port of Malabo or Port of Bata, our senior engineers deploy to your site to supervise structural installation, direct cold commissioning, and lead technical training programs for local operations crews in Spanish or French.
*All systems manufactured conform strictly to ASME Section VIII Div 1, Chinese National Standard GB150, and international ISO 9001/14001 quality frameworks.
