Tianjin Capital Environmental Protection Group Company Limited (1065.HK): Mission and Values

• Sewage water processing and sewage treatment plant construction - design, build, operate and transfer (DBOT)/EPC contracts and ongoing O&M contracts for municipal and industrial sewage facilities.
• Recycled water and auxiliary projects - production and sale of reclaimed water, water distribution networks, and ancillary services tied to industrial parks and municipalities.
• Heating and cooling supply services - centralized heating/cooling systems for urban districts and industrial complexes, often under long-term concession or service contracts.
• Environmental protection equipment customization - engineering, manufacture and installation of water and waste treatment equipment for in-house projects and third parties.
• Hazardous waste treatment - collection, treatment and disposal services for hazardous and medical wastes with licensed treatment facilities and fee-for-service contracts.
• Construction and management of related facilities - project development, financing, construction management, and entrusted operations of environmental infrastructure.

• Recurring service income - long-term O&M, water sales and heating/cooling supply contracts provide stable, predictable cash flows and service margins.
• Project construction revenue - EPC/engineering contracts generate lump-sum construction revenue and equipment sales, typically with lower margin but higher near-term cash inflows.
• Asset-based returns - investments in concession-style projects or BOT/BOOT plants yield steady returns over concession life through tariffs and availability payments.
• Hazardous waste fees - per-ton treatment fees for hazardous waste contribute higher-margin, specialized-service revenue streams.

• Project types - EPC, DBOT/BOT, concession and entrusted operation models tailored by client and municipality.
• Financing mix - combination of corporate cash, project-level debt, and sometimes municipal or government-backed financing for large infrastructure projects.
• Risk allocation - construction risk typically borne during EPC phase; operational and demand risk managed via long-term contracts with municipalities, industry clients or availability-based payments.

• Water sales and heating/cooling tariffs produce recurring operating cash inflows with seasonal and tariff-adjustment features.
• O&M contracts reduce customer acquisition cost and create opportunities for margin expansion through scale, standardization and asset utilization.
• Construction/EPC work drives short-term revenue spikes; margin management and timely contract completion are critical for converting backlog into profit.
• Value-added equipment sales and hazardous waste services offer higher blended margins, improving overall profitability.

• Diversified service lines reduce single-segment exposure and enable integrated project delivery (from design and equipment supply to long-term operations).
• Technical capabilities in hazardous waste and equipment customization create differentiation versus pure-play water operators.
• Scale (2,321 employees) supports simultaneous multi-region project execution and long-term O&M commitments.

Tianjin Capital Environmental Protection Group Company Limited (1065.HK): How It Works

• Sewage treatment - urban and industrial wastewater collection and biological/chemical treatment, billed via treatment fees and government concession agreements.
• Recycled water - production and sale of reclaimed water to industrial and municipal users under purchase agreements.
• Water supply - bulk water sales and utility operations under concession/PPP arrangements.
• Energy cooling and heating - centralized heating/cooling services and energy management for industrial and district clients.
• Sludge treatment - treatment, disposal, and resource recovery (e.g., dewatering, heat recovery) with treatment fees.
• Hazardous waste treatment - licensed collection, incineration, and disposal for industrial hazardous streams under contractual fees.

• Operation & maintenance (O&M) contracts - recurring cash flows from long-term O&M of municipal/industrial facilities.
• Construction & EPC - revenues from building new plants and infrastructure (engineering, procurement, construction), often recognized per contract milestones.
• Environmental equipment & technology - sale and customization of treatment equipment and integrated systems.
• Resource sales & byproducts - recycled water, recovered materials, and energy sales supplement service fees.
• Public-private partnerships (PPP) and concessions - capital-light models where the company operates assets under long-term concessions, collecting regulated user fees.

• Tariff collection: municipal and industrial tariffs set by local authorities or agreed in contracts provide predictable cash inflows for water and sewage services.
• Contract diversification: mix of short-term EPC revenue and long-term O&M/PPP recurring income smooths revenue volatility.
• Scale and integration: cross-selling of recycled water, sludge treatment, and energy services on existing sites increases average revenue per project.
• Regulatory tailwinds: stricter environmental standards and government investment in infrastructure drive new project pipelines and aftermarket equipment sales.
