We put the energy customer into the project before we select the equipment. Our investigation of Gangnam centers on a decision that can transform a waste-to-energy proposition: connecting a defined treatment obligation with a useful, contracted heat demand.
For Klean, the opportunity is to develop both ends of the business together. Waste commitments establish what the plant must receive, while steam requirements establish what it must deliver. We connect those obligations through process selection, site engineering, and the financial model, so the energy opportunity has a credible route to revenue.
Installed capacity earns its value through use. Seoul’s shared-treatment history shows how municipal boundaries and service agreements can constrain that use even when treatment equipment is available. Gangnam began shared treatment in 2007, with Gwanak joining in 2013, and across Seoul’s four-facility system the reported operation rate rose from 33% in 2006 to 85% in 2013, a historical system measure, not Gangnam’s individual availability. It explains why we examine waste-routing agreements before recommending additional capacity. Our first development decision is to establish the dependable catchment: material quantities and quality, transport distances, acceptance conditions and each participant’s obligations. Plant scale follows the service that can actually be organized.
Gangnam’s three 300-tonne-per-day stoker lines provide 900 tonnes per day of design capacity. Completed in December 2001, the facility combines waste treatment with an urban energy outlet. A February 2026 on-site public-broadcast report describes waste arriving from eight districts and approximately 2,600 tonnes of steam sold daily from around 3,000 tonnes produced.
Those reported daily quantities describe a snapshot, so we do not turn them into an annual sales forecast. Our engineering work begins with the customer’s pressure, temperature, seasonal demand and interruption requirements, together with the cost of delivering steam across the site boundary. This is where our technical and investment perspectives meet: a boiler can produce steam, but the commercial arrangement can still leave a project exposed to low demand, connection costs, or outages. We develop the process and the offtake basis together, including metering, responsibility for shared infrastructure and the operating arrangements needed when either party stops.
Environmental controls and community facilities are also part of the service—reagents, monitoring, internal power, residues and maintenance belong in the operating budget, and a host community’s relationship with the facility continues after the construction team leaves. Our Australian wood-waste feasibility work applies this same discipline to industrial energy demand, connecting the available material with useful electricity and heat before developing the investment case. The benefit for clients is a project built around the energy they can use or sell.
We make useful demand a condition of the investment case. Gangnam provides operating evidence for the physical connection between municipal waste and a steam customer. Its historical finances also show why recovered energy must be assessed within the whole treatment service.
| Published financial measure | Original currency | Approximate USD equivalent |
|---|---|---|
| Historical construction | KRW115,500.000 million | US$85.87 million |
| Facility revenue 2012 | KRW19,794.000 million | US$14.72 million |
| Facility expenses 2012 | KRW21,338.000 million | US$15.86 million |
| Revenue less expenses 2012 | KRW-1,544.000 million | -US$1.15 million |
The 2012 figures are a historical municipal revenue-and-expense comparison. The difference is simple subtraction, not current EBITDA or a private-equity return, and it shows why our assessment includes treatment fees or public funding alongside energy sales, operating costs, and capital renewal. An aging plant must also preserve that service during a transition: maintenance arrangements and proposals for underground replacement featured in reporting reviewed for the research edition, but those plans are not completed capacity. We assess renewal around current equipment condition, alternative waste destinations and the heat customer’s requirements.
Our conclusion for a client is concrete: first secure the supply and demand commitments, then design the facility and funding around them. That can change the preferred site, the plant scale and the most valuable next investment.
1. Secure the catchment before buying capacity.
Agree waste quantities, acceptance requirements and municipal responsibilities before committing to plant scale.
2. Develop the heat contract with the process.
Steam conditions, seasonal demand, connection costs and outage duties must support the same commercial proposition.
3. Fund the entire service.
Include treatment income, environmental obligations and major renewal in the model, alongside energy sales.
These three takeaways highlight investment decisions, not guaranteed project outcomes. We define performance commitments, commercial responsibilities, and information access within the agreed project scope and contracts.
Do you have a municipal waste stream and a district-heating or industrial steam customer? Bring us both sides of the opportunity, and we will define the feasibility scope that connects the waste commitment, the energy requirement, and the investment decision.
For a suitable new facility, our paid Detailed Equipment Quotation establishes the pre-feasibility equipment and budgetary basis, and a Detailed Feasibility Study evaluates project-specific viability before FEED where justified. Existing assets and investment opportunities begin with a separately scoped paid assessment.

ABOUT THE INFORMATION PRESENTED
We develop waste-to-value projects by connecting technology, engineering, resource markets and investment assessment across the Klean Group. Our work spans feasibility, equipment and systems definition, project integration and asset improvement. We share selected project information and learning while protecting confidential client details and proprietary know-how, and an inquiry, NDA, or paid engagement does not automatically grant access to restricted information or facilities.
This case connects with Goals 7, 9, 11 and 12 through energy recovery, industrial infrastructure, sustainable communities and responsible production.
