At Qingdao Haiyue, we are dedicated to green energy and environmental protection, transforming agricultural organic waste and crop residues into renewable energy and valuable resources. Our innovative approach injects new vitality into sustainable development, supporting both environmental conservation and local agricultural progress.
From Waste to Resource
Agricultural residues and animal manure collected from farmland are transported to biogas processing plants equipped by Qingdao Haiyue. These seemingly insignificant agricultural wastes gain new value, serving as essential raw materials in the biogas production process. Crop residues are carefully stored to prevent degradation, ensuring availability for future use, while animal manure is securely kept in specialized facilities with advanced odor control systems, effectively addressing traditional agricultural waste management challenges.
Inside the biogas equipment, these raw materials undergo a remarkable transformation. They are fed into a series of airtight and highly efficient anaerobic digesters, where microorganisms play a crucial role in breaking them down. This microbial decomposition process generates biogas, a clean and sustainable energy source. Qingdao Haiyue ensures a fully controlled and environmentally friendly production process, preventing harmful gas emissions and truly achieving green energy generation.
Once produced, biogas is collected and refined through advanced separation technology to create high-purity biomethane. This biomethane is not only clean and eco-friendly but also has a high energy density, making it an excellent alternative to fossil fuels. Part of the biomethane is injected into the national grid, supplying households with clean energy, while another portion is used for on-site power generation, sustaining production operations and providing necessary heating for the digesters—achieving a closed-loop energy system.
A key byproduct of the biogas process, digestate, is equally valuable. As a natural biofertilizer, digestate is rich in beneficial microorganisms and nutrients, significantly enhancing soil structure and fertility while replacing carbon-intensive chemical fertilizers. At Qingdao Haiyue, digestate is safely stored and transported to farmland, contributing to healthier crops and more sustainable agriculture.
With digestate enriching farmlands and biomethane powering homes, Qingdao Haiyue’s circular economy model not only reduces reliance on fossil fuel imports and lowers carbon emissions but also provides additional income opportunities for local farmers. This sustainable approach strengthens regional economies while contributing to global efforts in combating climate change.
