Recently, all 40 participants of the "Special Training Course on Improving Professional Capacity for Comprehensive Utilization of Manganese Residue of Xiushan Ecological Environment 2026" visited Vary Tech's Low-Carbon Exhibition Hall for on-site inspections and technical exchanges.
The 5-day training course was entrusted by the Bureau of Ecology and Environment of Xiushan Tujia and Miao Autonomous County, Chongqing Municipality, and undertaken by the School of Humanities, Central South University. This cross-regional integration of theoretical learning and practical field visits aims to jointly explore new paths for solid waste resource utilization and local green transformation and development.
As a key project approved under the non-degree education program of Central South University, this training course closely aligns with the pollution control practices carried out in Xiushan County in recent years, focusing on comprehensively improving professional capabilities covering the remediation of legacy pollution issues, comprehensive utilization of manganese residue and pollution treatment.
At present, guided by the "Two Mountains" Theory, Xiushan County is actively promoting the in-depth integration of phasing out backward production capacity and green development models. As an industry frontrunner with 20 years of in-depth engagement in solid waste resource utilization, Vary Tech's core technological assets are highly aligned with the green transformation strategy of Xiushan County.
Inside Vary Tech's Low-Carbon Exhibition Hall, the training participants systematically learned about the company's profound technological accumulation in solid waste treatment via multimedia presentations, patent exhibitions and industrial operation cases. The trainees carefully observed scale models and actual equipment of Vary Tech's oxygen-free pyrolysis system for organic solid waste, and held in-depth discussions on application scenarios of its three core technologies: mechanical crushing & sorting, oxygen-free pyrolysis and rapid biodegradation.
In addition to cutting-edge pyrolysis equipment, the training group showed strong interest in the self-developed "Three Islands and Two Networks" system built by Vary Tech, and witnessed the actual operation of its digital recycling system on site. Supported by physical networks consisting of Blue Houses (classified drop-off and collection points), Blue Vehicles (classified transport fleets) and Blue Islands (classified disposal hubs), as well as an online IoT-enabled big-data intelligent cloud platform, this system realizes full-category waste recycling covering urban and rural public institutions, residential communities and all other scenarios, linking micro-level collection with macro-level circular economy circulation.
When deployed at the county level, the "Three-Island Collaboration, Two-Network Integration" model realizes coordinated treatment of diverse solid waste through modular and standardized construction of ecological islands for circular economy industries.
Blue Islands: Responsible for efficient recycling and circular utilization of waste materials within the county to revitalize idle resources, including micro blue islands, small blue islands, medium blue islands, full-category large blue islands, and specialized blue islands dedicated to the recycling and processing of specific materials such as scrap metal and waste plastics.
Carbon Islands: Focus on organic solid waste generated in the county including agricultural and forestry residues, waste tyres, waste plastics, oily sludge and sewage sludge, and achieve low-carbon circular conversion of resources via core proprietary technologies.
Green Islands: Conduct harmless treatment of perishable organic matter from the county and realize soil carbon sequestration through returning organic matter to soil.
This collaborative three-island model integrated with dual networks and systematic digital platform support breaks the fragmented, single-mode limitations of traditional solid waste treatment, and delivers innovative solutions for coordinated county-wide environmental governance to Xiushan County.
The training participants spoke highly of Vary Tech's systematic innovations and industrial achievements in the resource recovery and harmless disposal of solid waste. All trainees agreed that this on-site exchange has broadened the horizons of ecological environment cadres, and provided valuable Vary Tech solutions and low-carbon insights for Xiushan County to further advance comprehensive county environmental governance and achieve high-level remediation of manganese residue.
