Leading Biogas Project Contractor Professional Solutions By Shijiazhuang Zhengzhong Technology Co., Ltd

At Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), we are proud to be a leading biogas project contractor, delivering comprehensive solutions for the design, construction, and operation of biogas projects worldwide. With over three decades of experience, our team has a strong foundation in wastewater treatment, biogas systems, and equipment manufacturing, making us a trusted partner in addressing complex environmental challenges.

Comprehensive Biogas Solutions for Diverse Industries
Center Enamel’s expertise spans multiple sectors, offering biogas project solutions tailored to the unique needs of industries such as agriculture, municipal wastewater, industrial wastewater, and high-concentration organic waste treatment. From the breeding industry to landfill leachate and kitchen waste, our biogas systems are designed to maximize energy efficiency, reduce waste, and promote sustainability.

We has developed a set of patented technologies for the biogas project, We collect, recycle and treat all kinds of organic waste from daily life, industry, agriculture, and animal husbandry in a scientific and environmentally friendly way. Using the mixed raw material fermentation technology that does not require the classification of raw materials and the maintenance-free super-large anaerobic reactor for waste heat insulation of biogas power generation, the gas production rate, and investment utilization ratio are effectively improved, and the sustainable and profitable commercial operation mode is realized in the biogas project.

We have a number of engineering design and construction cases for different raw materials such as livestock and poultry manure, crop straw, kitchen waste, high concentration organic wastewater. The self-developed high-efficiency anaerobic fermentation unit can fully mix the raw materials, solve the "capping phenomenon" on the liquid surface of the reactor, with a high volume gas production rate and stable operation. The self-developed anaerobic reactor heating system has the characteristics of instant automatic heating, low energy consumption and stable operation. The waste heat from biogas generation was used to heat the thermal insulation heating system outside the reactor, which greatly improved the gas production rate and investment utilization rate, and made the reactor work normally all year round.
