Industrial biogas includes biogas from the fermentation of organic wastewater or waste in industrial fields, and landfill gas included.  

    Over the years, Fairyland has been focusing on large-scale biogas projects that existed in waste treatment plants, alcohol plants, tanneries, paper mills, food factories, pharmaceutical companies, and other industries.

    The biogas obtained from the anaerobic digestion process, after pressure balance，storage, desulfurization, dehumidification, particle removal, and pressure adjustment, enters the engines to generate electricity and then connect to the national grid or provide power and heat to the plant itself. It can also be purified and then compressed to CNG that is injected into the municipal gas pipeline or sold as civil and automotive natural gas.
