Qingdao Ocat International Trade Co., Ltd. — International Office of Weifang Jinjue

Who We Are

Qingdao Ocat International Trade Co., Ltd. (OCAT) is the international business office of Weifang Jinjue Environmental Protection Technology Co., Ltd., established in Qingdao in 2013. We are solely responsible for the import and export, as well as the international operations, of the group's full product portfolio. Acting as the global gateway for the group's renewable-energy and environmental-protection solutions, OCAT connects overseas customers with trusted Chinese manufacturing, from first inquiry to delivered project.

Our Manufacturing Backbone

Behind OCAT stands Weifang Jinjue Environmental Protection Technology Co., Ltd., a professional manufacturer and solution provider of biogas systems and environmental equipment. Founded in 2002 in Weifang, Shandong Province, with a registered capital of USD 4.5 million, the company operates an integrated, one-stop service covering project design, equipment manufacturing, on-site installation, commissioning, and ongoing technical support. Its solutions are applied across agriculture, livestock farming, municipal wastewater treatment, and industrial organic-waste management — turning organic waste into clean, usable energy with proven technology.

What We Do

OCAT handles the international trade of the group's biogas and environmental product lines, including:

• Medium- and large-scale biogas systems
• Biogas power-generation systems
• Wastewater treatment systems
• Organic-fertilizer systems
• Desulfurization & purification systems
• Double-membrane gas holders (biogas storage)
• Red-mud PVC fermentation bags
• Biogas storage bags

Our flexible PVC engineering materials are produced to Chinese national standards using a hot-melt coating (semi-coated) process, rated for a working temperature range of -40°C to 60°C — engineered specifically for soft-shell biogas engineering.

Note: We have deliberately focused OCAT's scope on biogas and environmental solutions. Products unrelated to biogas (such as water tanks, swimming pools, fish ponds, drinking-water bags, oil bags, and bridge pre-pressure tests) are NOT part of OCAT's offering.
