At Henan Ruzhou Muyuan Foods, the world's largest pig farming enterprise, the once-perpetually burning biogas flare has been permanently extinguished. It has been replaced by a clean energy pipeline, now smoothly connected to the Ruzhou ENN gas network. This shift from an "agricultural waste emission cost" to a "green, zero-carbon power source" vividly illustrates China's agricultural green transformation and serves as a practical example of ENN's efforts to build a modern industrial system through its digital and intelligent capabilities.
As the national "dual carbon" strategy advances, the "Plan for Accelerating the Construction of an Agricultural Power (2024–2035)" explicitly calls for the comprehensive integration of digital technology with modern agriculture to establish a green, low-carbon, and circular agricultural industry system. The energy utilization of biomass resources is a crucial pathway for achieving zero-carbon goals and source-level governance, as well as a key lever for balancing corporate ecological responsibility with operational efficiency.
The collaboration between ENN and Ruzhou Muyuan is a typical case within this wave of green transition. Guided by the concept of pan-energy, ENN employs a systemic approach that "looks beyond energy to manage energy," deeply integrating digital intelligence with industrial scenarios. This has enabled the successful conversion of biogas—once flared as an "emission burden"—into a green gas source suitable for grid connection and capable of generating stable revenue, through processes like "complex iron desulfurization and pressure swing adsorption decarbonization." Consequently, Ruzhou Muyuan has evolved from its original roles in livestock production and environmental responsibility to a new role as a stable supplier of green energy, optimizing its development model.
Large-scale livestock farming faces dual challenges of "environmental protection and profitability." Ruzhou Muyuan, a core pig farming base in Henan with an annual output exceeding one million heads, produces over four million cubic meters of biogas annually from manure through anaerobic fermentation. Prior to the upgrade, only 42% of this biogas was used on-site, with the remaining nearly 60% flared, resulting in resource waste and emission pressures. This underutilization of biomass resources also subjected the company to operational pressures from environmental regulations, emission reduction compliance, and rising governance costs.
"Handling massive amounts of livestock manure is a primary challenge. Most of the biogas produced from fermentation is either left unused or flared, polluting soil and water sources while releasing significant methane, increasing regional emission reduction burdens," explained an industry insider. Methane has a global warming potential over 21 times that of carbon dioxide over a century, and its uncontrolled discharge severely impacts the ecological environment, forcing companies to invest heavily in pollution control.
Ruzhou Muyuan's predicament is not unique. Across Henan and nationwide, many large-scale farming enterprises have basic biogas facilities but are constrained by a lack of professional digital management tools, cost-effective systems, and operational frameworks. As a result, biogas utilization often remains at inefficient on-site use or direct flaring stages. Manure in fields, flaring on-site, and rising environmental costs on balance sheets paint a realistic picture of the industry. Against the backdrop of "dual carbon" goals and agricultural green transition, innovatively addressing the dual dilemma of environmental protection and profitability has become essential for the industry to break through development bottlenecks and cultivate green core competitiveness.
The "Muyuan Model": Reshaping Sustainable Momentum for Industrial Green Development with Systemic Capabilities. Addressing the needs of green upgrades in animal husbandry, ENN, centered on its pan-energy concept, customized a full-process solution of "complex iron desulfurization and pressure swing adsorption decarbonization" for Ruzhou Muyuan. This established an integrated system covering biogas collection, purification, and grid connection. The system can process 600 cubic meters of biogas per hour, purifying it into biomethane with a methane concentration exceeding 96%, which is then fed into the Ruzhou ENN gas network via a dedicated pipeline, supplying up to 1.56 million standard cubic meters annually.
Compared to traditional single-pollution-control approaches, the core value of ENN's solution lies in its systemic optimization of corporate energy management, establishing a dual-loop business model of "environmental governance + energy value addition." Biogas at Ruzhou Muyuan is no longer viewed as a "byproduct disposal issue" but is integrated into the company's medium- to long-term operational system, representing the true value of the role transformation facilitated by ENN's involvement.
Biogas has shifted from passive disposal to efficient resource utilization. The purified biomethane is directly supplied to the urban gas network, creating a dual-utilization pattern for both on-site use and external sales, successfully enabling the market circulation of green energy. While strictly adhering to environmental emission standards, the company has secured stable revenue, transitioning from pollution control expenditures to income generation from clean energy, with annual gains nearing one million yuan. What was once an overlooked "weak energy source" has gradually become a "new leverage point" driving corporate transformation, fundamentally strengthening the industry's sustainable development foundation.
The value of ENN's "Muyuan Model" extends beyond the company's own profit enhancement, fostering a win-win situation for the region and society. The local biomethane supply to the gas network supplements the urban gas market with stable, clean gas sources, further optimizing gas procurement structures and stabilizing operational costs. Simultaneously, various scattered biomass resources are integrated for intensive utilization, significantly improving comprehensive resource utilization rates and injecting robust momentum into the green transformation and upgrading of the regional energy structure.
Exploring a Replicable Pathway for Agricultural Green Development. ENN's successful practice at Ruzhou Muyuan not only updates the traditional energy consumption model for individual enterprises but also provides a replicable new model for green development along the "resource-energy-end user" chain.
Beyond Muyuan, many enterprises in Henan, such as alcohol and starch producers like Weihui Jiaxin, possess potential for organic waste resource development. Leveraging the pan-energy development concept, ENN tailors solutions based on different enterprises' resource endowments and operational conditions, establishing comprehensive biogas purification and utilization systems. This not only helps companies reduce reliance on fossil fuels but also significantly enhances their energy-related income.
Building on accumulated industrial experience, ENN is accelerating the large-scale promotion and iterative upgrading of this pathway. Centered on integrated energy-carbon solutions, the approach is expanding from animal husbandry to diverse sectors like alcohol and starch production, paper processing, and waste-to-energy, fully tapping into the resource value of organic waste. Projects such as Xinxiang Xing Shouchuang Environment and Luoyang Yichuan Chengfa Waste-to-Energy Plant are already underway, enabling more enterprises to benefit from intelligent and green transformation. By systematically integrating "overlooked energy" into regional energy systems and leveraging digital intelligence to advance agricultural intelligence and green upgrades, ENN is injecting sustainable momentum into the implementation of the "dual carbon" strategy.
