33 Years of group heritage, 12 Years of biogas focus —
a closed-loop biogas purification service provider from financing to O&M.
Chintech Innovation (Shanghai) Technology Development Co., Ltd. focuses on biogas purification and resource utilization. Leveraging full-cycle group capabilities, we provide end-to-end service — from investment consulting, planning and design, infrastructure engineering, through equipment installation, commissioning, operation, and after-sales maintenance.
We adhere to the four-in-one operating principle: "Fair Pricing · Reliable Quality · Rapid Response · Craftsmanship." As a co-drafter of 2 industry/group standards, we aim to become a leading technology enterprise in the green energy sector.
From Anaerobic Fermentation, to Biogas Purification, to Grid Injection & Sales —
we operate the full biomethane value chain.
CTI masters Membrane Separation, Pressure Swing Adsorption (PSA), MDEA Amine, High-Pressure Water Scrubbing four core CO₂ removal technologies, combined with desulfurization methods including wet complexed iron, dry iron oxide, and acidic/alkaline biological desulfurization — solutions tailored to feedstock properties and downstream user profiles.
After purification, methane concentration reaches ≥ 96%, meeting the Class I gas standard of GB/T 41328-2022. It can be directly injected into city gate stations, compressed into CNG, or used as feedstock for green methanol, green LNG, and SAF.
Multiple operating and under-construction biomethane projects, distributed across county-level energy bases in East and Northeast China, forming a scaled industrial cluster.
Our projects concentrate in county-level areas with dense biomass resources, adopting flexible cooperation models such as BOO, EMC, and EPC+O. Feedstock sources span municipal leachate biogas, agricultural straw and manure biogas, and industrial wastewater biogas. Process routes include alkaline/acidic biological desulfurization, wet complexed iron, dry iron oxide, membrane separation, PSA, MDEA amine, and high-pressure water scrubbing — each project tailored to feedstock properties and downstream user profile.
Broad and Quality Sales Channels —
Stable Downstream Partner Network
Locking in CTI's downstream certainty.
CTI is a domestic leader in green gas — a core member organization, participating across production, certification, verification, monitoring, trading, and off-take — with priority access to new revenue streams.
Leveraging industry resources, the company is also developing Green LNG, Green CO₂, Green Hydrogen, Green Methanol— extending the biomethane value chain into the high-value segments of ESG and green certificate markets.
