Summary of Key Points
The expansion of AI infrastructure (such as data centers and computing facilities) has opened up new business opportunities for the environmental protection industry. These opportunities no longer revolve around traditional "end-of-pipe pollution treatment" methods (e.g., building wastewater treatment plants), but rather involve integrating environmental considerations into the daily operations of these facilities to ensure they operate 24/7, are energy-efficient, and comply with regulations. There are four main types of new demands: continuous services for water and cooling systems, green upgrades of existing data centers, waste incineration in conjunction with computing capabilities, and the disposal of retired servers. However, for environmental companies to secure these contracts, they must address four critical issues: "who will buy, what will be purchased, how payment will be made, and who will assume responsibility."
1. AI Infrastructure Transforms Environmental Protection from "Post-Clean-up" to "Pre-Operational Maintenance"
In the past, the environmental protection industry focused on remedial actions—building wastewater treatment plants and waste incineration facilities to deal with pollution that had already been generated. Now, with the ongoing operation of AI infrastructure (such as data centers), there is a need for timely cooling of high-density servers, stable water supply, energy efficiency for outdated equipment, and secure data destruction for retired devices. All these measures are essential to ensure uninterrupted computing operations, shifting the focus from end-of-pipe treatment to becoming an integral part of the production system.
More importantly, the clients have changed. Previously, they were mainly governments or municipal entities; now, they include data center owners, operators, park water service companies, and cloud service providers. Their priority is not just compliance with emission standards but ensuring that systems do not fail. For example, when evaluating cooling systems, they consider not only equipment specifications but also the ability to maintain stable temperatures even under varying server loads.
2. Water and Cooling: Moving from Selling Equipment to Providing "Continuous and Stable Services"
Cooling in data centers is far more complex than just using air conditioning; it involves a complete water system that includes water source access, reclaimed water supply, anti-scaling and corrosion protection for circulating water, wastewater treatment, and real-time monitoring. A concrete example is China Tower Jiangsu Branch's two-year water treatment maintenance contract for a Nanjing data center, valued at 1.28 million yuan—this demonstrates that the need for continuous water treatment has evolved from a technical concept to a actual business opportunity.
There are also opportunities related to reclaimed water usage: Zhengzhou requires that non-potable water (e.g., for cooling) used in data centers account for 50% by 2027, and the Zhongwei Data Center Cluster has implemented a wastewater recycling project capable of processing 6,000 cubic meters of industrial waste daily. To turn this into a stable source of revenue, clear agreements on water quality, quantity, price, and backup water sources must be established. It's important to note that liquid cooling does not necessarily increase water consumption (some closed-loop systems can even reduce evaporation); environmental companies can gain benefits in terms of water supply assurance, stable water quality, and compliance with discharge regulations. Only by providing continuous services from the design phase can they turn this into a long-term business opportunity.
3. Green Upgrades of Existing Data Centers: Energy Efficiency Without Downtimes
Many older data centers have a PUE (the ratio of total electricity consumption to server-specific electricity usage, with lower values indicating greater efficiency) higher than 1.35 and cannot be relocated due to operational constraints. Under policy pressure, owners are now taking the initiative to upgrade their facilities:
- Beijing Policy: Starting in 2026, data centers with high PUE will face differential electricity pricing; energy-efficient upgrades can receive up to 30% of the investment cost as a reward (with a cap of 30 million yuan per project).
- Upgrade Examples: The Wenzhou Binhai Data Center upgraded its natural cooling system, achieving an 35% reduction in energy consumption; the Fuzhou Mobile Data Center optimized its cooling system using AI, resulting in nearly 4,000 hours of natural cooling annually and a 30% energy saving.
- Payment Model: The payment model is based on "Energy Performance Contracting (EMC)": the company upgrades the facilities and receives a share of the energy savings, while also ensuring uninterrupted operations. For instance, the Sichuan Tianfu Information Center's upgrade required online construction, with energy-saving data being uploaded to a corporate platform, and the split over three years amounted to no more than 13.82 million yuan.
4. Waste Incineration + Computing: An Attractive Concept but with Challenges
The idea of using waste incineration to generate electricity and provide cooling for data centers is appealing in theory, but practical implementation faces hurdles:
- Technical Feasibility: While waste incineration is technically feasible, the integration with data centers is still in its early stages. For example, the Shanghai Liming Incineration Plant has successfully provided cooling for a park, but projects to supply cooling to data centers (such as the Liming Intelligent Computing Center) are still under development and have not yet generated stable revenue.
- Unclear Commercial Contracts: Issues such as who will pay for green electricity or cooling services, how to share investment in infrastructure (e.g., power lines and backup power), and who is responsible for scheduling remain unresolved, making this a nascent but high-value area of opportunity.
5. Disposal of Retired Servers: Not Just Recycling, but a Business Focus on Data Security and Asset Management
The expansion of computing capacity means a large number of servers will be retired. The disposal process involves more than just physical dismantling:
- Tencent's Approach: Servers are first inventoried and classified; those that can still be used internally are reused (a reduction of 4,980 tons of electronic waste by 2025), while those that cannot are securely data-deleted before being dismantled (759 tons).
- Environmental Companies' Role: Their role shifts from simply handling waste to providing comprehensive services, including asset inventorying, testing and grading, data destruction, reusing equipment, and ensuring traceable transportation. Customers are most concerned about data security and maximizing the residual value of the equipment; compliance with environmental regulations is secondary.
Conclusion
To capture these new opportunities, environmental companies must adapt to the changing landscape:
- Identify the right clients (e.g., data center operators or cloud service providers).
- Provide tangible results (stable water supply, energy savings, data security) rather than just selling equipment.
- Accept flexible payment models (maintenance contracts, EMC arrangements, asset buybacks).
- Assume operational responsibilities (ensuring uninterrupted operations and continuous monitoring).
By transforming their traditional environmental protection capabilities into services that support the smooth operation of computing facilities, companies can seize these new business opportunities.
