The food processing industry is a vital sector that provides a wide range of products for global consumption. However, the byproducts of this industry, including organic waste, wash-water, and production residues, pose a significant waste management challenge. If not handled properly, these waste streams can lead to environmental pollution and create a substantial financial burden for companies. Fortunately, this organic waste is also a valuable resource. Through the process of anaerobic digestion, it can be converted into biogas, a clean, renewable fuel source, and a nutrient-rich digestate that can be used as fertilizer. At the very core of this sustainable process is the biogas tank, a meticulously engineered container that serves as the main reactor for the biological conversion. The success of a food processing plant’s waste-to-energy system is directly dependent on the performance and durability of its digestion tanks.
Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), a global leader in containment solutions, has engineered the ideal answer with its advanced Biogas Tanks. Our tanks are specifically designed to meet the rigorous demands of food processing environments. Utilizing robust Glass-Fused-to-Steel (GFS) technology, our tanks provide a secure and stable environment for microorganisms to efficiently break down organic waste and produce biogas. By offering a containment solution that is highly resistant to corrosion, easy to install, and built for long-term reliability, our tanks are fundamental to maximizing the efficiency of biogas production, ensuring responsible waste management, and helping plants reduce their operational costs.
Center Enamel’s Biogas Tanks are a superior solution for anaerobic digestion, built to address the unique challenges of containing and processing organic waste from the food processing industry. The core of our technology lies in the use of high-quality materials and precision engineering, which ensures exceptional performance and durability. This innovative design offers a multitude of advantages that directly benefit biogas production and plant operation.
The primary advantage of our biogas tanks is their unmatched durability and corrosion resistance. The Glass-Fused-to-Steel technology creates an incredibly strong bond between enamel and steel, providing a non-porous and chemically inert surface. This unique coating makes the tanks highly resistant to the corrosive gases and acids produced during anaerobic digestion, ensuring a long service life with minimal maintenance. Unlike concrete or other traditional materials, GFS tanks do not suffer from spalling, cracking, or material degradation from prolonged exposure to harsh digester environments. This resistance ensures the structural integrity of the tank is maintained, providing a reliable and safe environment for the digestion process.
Another key advantage is the enhanced structural integrity and rapid installation. Our tanks are constructed from standardized, factory-coated panels that are bolted together on-site. This modular design simplifies the installation process, significantly reducing construction time and labor costs compared to traditional cast-in-place concrete tanks. The precision manufacturing of each panel ensures a perfect fit, creating a strong and reliable structure. This pre-fabricated system also allows for greater flexibility, as tanks can be easily expanded, relocated, or even disassembled if needed. The bolted design is a key differentiator, providing a robust solution that is both efficient to deploy and easy to maintain.
Furthermore, the design of our tanks allows for optimal process control and hygiene. The smooth, inert surface of the GFS panels prevents the buildup of bacteria and algae, which can interfere with the anaerobic digestion process. This hygienic surface ensures a clean environment that supports the health of the microbial community, leading to more stable and efficient biogas production. Additionally, the tanks can be equipped with various accessories and fittings for monitoring temperature, pressure, and pH levels, allowing for precise control over the digestion process. This adaptability, combined with the low maintenance requirements and superior containment capabilities, makes our biogas tanks a premier choice for any anaerobic digestion application.

Center Enamel's Biogas Tanks are a key component in a wide range of industrial and agricultural biogas projects, providing a reliable main container for anaerobic digestion. In food processing plants, these tanks are used to process organic waste, including wastewater, food scraps, and byproducts. This helps facilities manage waste products responsibly while generating a valuable energy source. The tanks are also essential in municipal wastewater treatment plants for the treatment of sewage sludge, which helps municipalities reduce their environmental footprint and generate power for their operations. Additionally, they are critical to agricultural waste treatment facilities, where organic waste from livestock manure and other farm residues is processed to produce energy. By providing a secure and durable reactor for the anaerobic digestion process, these tanks help facilities handle their waste responsibly while simultaneously generating a reliable renewable energy source and controlling odors. The versatility of our biogas tanks makes them suitable for a diverse range of applications, from small-scale digesters to large, complex industrial biogas plants.
As a premier provider of bolted tanks and containment systems, Center Enamel has established a global footprint with numerous successful projects. The following non-fictitious cases, selected from our extensive portfolio, demonstrate our capacity to deliver high-quality biogas solutions for industrial and agricultural waste treatment.
Thai Brewery Wastewater Treatment Project: We supplied 5 tanks with a total capacity of 21,500 cubic meters for a major brewery wastewater treatment project in Thailand. These tanks served as the core containers for the facility's anaerobic digestion process.
Mexico Sugar Cane Processing Wastewater Project: We provided 3 tanks with a total capacity of 13,200 cubic meters for a sugar cane processing plant in Mexico. These tanks were an integral part of the plant’s system, used as the main reactors for the digestion of organic waste.
