SHANGHAI, April 29, 2025 /PRNewswire/ — The 26th IE Expo China was held at the Shanghai New International Expo Center, where Vary Tech, a pioneer in solid waste resource utilization for over 20 years, showcased its groundbreaking “Three-Island” model. This innovative framework integrates urban-rural waste recycling and low-carbon systems, earning Vary Tech a spot in the IE Expo TOP 100 Enterprises list. Through keynote speeches and strategic partnership signings, the company highlighted its leadership in pyrolysis-driven technologies and circular economy solutions, attracting widespread industry attention.
Three-Island Cooperate: Revolutionizing Solid Waste Management Across Scenarios
As a strategic partner of IE expo, Vary Tech’s “Three-Island” integrated solution—combining physical, chemical, and biological approaches—emerged as a focal point. This full-chain solution addresses challenges in solid waste management, spanning domestic, industrial, and new energy sectors, offering replicable and diversified pathways for global waste treatment.
Blue Island System: Building a Comprehensive Recycling Network
The Blue Island system, based in mechanical crushing and sorting technologies, establishes a precise, large-scale recycling network for all categories of resources. From household appliances and waste vehicles to plastics, textiles, paper, metals, and lithium batteries, all materials find opportunities for “rebirth.” Supported by an innovative digital recycling platform, the system integrates intelligent front-end collection, meticulous mid-end sorting, and efficient back-end processing, significantly enhancing resource utilization and accelerating the development of “urban mines.”
Energy Island System: Tackling Organic Waste via Pyrolysis
Central to the Energy Island system is Vary Tech’s 6th-generation oxygen-free pyrolysis technology, which processes over 30 types of organic waste, including plastics, tyres, and EV batteries. With a daily capacity of 240 tons per unit, this system reduces emissions while converting waste into energy and raw materials. By prioritizing pyrolysis-based solutions, Vary Tech addresses the “impossible triangle” of efficiency, cost, and sustainability in waste management.
Green Island System: Maximizing Waste Utilization
The Green Island system utilizes molecular membrane fermentation and biological recycling to manage biodegradable waste such as garden debris, food waste, straw, and livestock manure. Through aerobic fermentation and MBT-RDF preparation technologies, these materials are transformed into nutrient-rich soil, organic fertilizers, or solid alternative fuels (RDF). Additionally, zero-carbon biomass utilization technologies convert agricultural and forestry waste into biocarbon, applied in agricultural fertilizers, fuel, activated carbon, and industrial smelting, ensuring complete resource utilization.
By synergizing physical, chemical, and biological pathways, Vary Tech has established a comprehensive technological matrix covering resource recycling, organic/hazardous waste treatment, biomass conversion, biocarbon production, and new energy waste transformation. This matrix not only provides tailored solutions for diverse waste challenges but also serves as an exemplary industrial model for “zero-waste city” initiatives.
Oxygen-free Pyrolysis: Solving the “impossible trinity” in the solid waste management industry
At the concurrent “2025 Green Manufacturing Development Forum,” Deputy General Manager Song Zhen of Vary Tech delivered a keynote speech titled “Oxygen-free Pyrolysis: A Low-Carbon Technology Driving Green Development,” sparking industry-wide discussions.
Under global carbon neutrality goals and plastic pollution treaties, traditional landfilling and incineration fall short. Pyrolysis, with its adaptability, industrial maturity, and carbon reduction advantages, has become a “last-resort” technology for complex waste. Among various pyrolysis methods, Vary Tech’s rotary kiln pyrolysis stands out for its versatility, stability, energy efficiency, and cost-effectiveness.
Multi-Layered Sealing: Near-zero leakage for continuous pyrolysis operations.
To address leakage risks during high-temperature pyrolysis, Vary Tech developed a multi-layered flexible sealing system combining physical, mechanical, and inert gas protection. This achieves near-zero leakage, enabling 24/7 continuous and safe operations.
Anti-Coking Design: Eliminates downtime with automated cleaning of pyrolysis equipment
The anti-coking + online cleaning technology prevents residue buildup in pyrolysis reactor and allows automatic cleaning without shutdowns, reducing maintenance downtime and extending equipment lifespan.
Heat Recovery and Utilization: Pyrolysis reduces energy consumption by 15% compared to traditional methods of solid waste management
By integrating heat recycling, thermal enhancement components, and tiered energy recovery designs, the system cuts energy consumption by 15% compared to traditional incineration, optimizing energy efficiency and emission reduction.
Vary Tech’s oxygen-free pyrolysis technology has been applied to over 30 types of organic waste, including plastics and tyres. In 2019, the company pioneered its chemical recycling of domestic waste plastics. Recognized globally, it is the sole Chinese member of the IBTC and collaborates with a Brazilian Fortune 500 mining giant to advance green metallurgy.
Dual Strategic Partnerships Anchor New Industry Growth
Vary Tech sealed two landmark agreements at the expo, driving innovation in waste management:
Zero-Waste City Resource Utilization Demonstration Base
Partnering with Shanghai Jiajinying, Vary Tech will deploy a 60,000-ton/year hazardous waste pyrolysis line, setting a benchmark for high-value resource recovery in the Yangtze River Delta.
Aluminum Recycling and Biomass Energy Development
A joint venture with Shenyang NEU-SANKEN focuses on pyrolysis-enhanced aluminum recycling and biomass energy systems, driving nationwide synergies in waste-to-resource innovation.
Vary Tech’s IE Expo showcase underscores China’s leadership in environmental technology. By championing pyrolysis-centric solutions across its Three-Island model, the company transforms waste from a liability into an asset, accelerating the global transition to a circular, carbon-neutral future.
