When organic waste is transformed into clean energy, and the circular economy illuminates a sustainable future — Qingdao Haiyue Membrane Structure Engineering Co., Ltd. is reshaping ecological value through innovative biogas technology.
With nearly two decades of deep cultivation in the biogas sector and over 20 national patents, Qingdao Haiyue has served more than 3,500 ecological projects worldwide. Leveraging cutting-edge technology with a desulfurization and purification efficiency of 99.5% per cubic meter, we transform agricultural waste, kitchen leftovers, and municipal sludge into “green oilfields.” Our independently developed CSTR high-efficiency anaerobic digestion system processes up to 500 tons per day, increasing biogas output by 40%—equivalent to the carbon reduction of planting 200,000 trees annually. This is not only an ultimate exploration of resource regeneration but also a firm commitment to a zero-carbon future through intelligent manufacturing.
From biowaste-to-energy projects on large-scale dairy farms, to urban food waste treatment centers serving millions; from Southeast Asian palm oil effluent biogas power plants, to biomethane upgrading and grid injection systems—we unlock the energy of every gram of organic matter and transform every molecule of methane into light and heat. Our AI smart cloud control system optimizes fermentation parameters 24/7, while 304 stainless steel double membrane gas holders ensure zero-leakage and safe operations—technology safeguarding our blue skies and clean waters.
With a focus on innovation grounded in the earth, we customize modular household biogas units to support rural revitalization, bringing clean blue flames to farmers’ kitchens. We develop CHP (combined heat and power) solutions for industrial parks, replacing traditional coal with green energy. For eco-cities, we build full-chain systems integrating collection, treatment, production, and utilization—turning waste into a circular resource.
From the shores of the Yellow Sea to the global stage, Qingdao Haiyue connects agriculture, energy, and the environment through biogas. We tackle pollution with high-temperature anaerobic digestion, enhance energy quality with membrane separation, and create lasting value through full-lifecycle service.
