One of Australia’s largest forest products companies is examining how its own wood waste could power its next production cycle. Klean is developing a Detailed Feasibility Study for converting those residues into electricity and useful industrial heat — recovering energy from the by-products of manufacturing and putting it back to work in the same value chain.
This is the circular opportunity at the heart of the project. An existing residual material stream becomes a potential source of local energy, connecting resource efficiency, industrial competitiveness and a lower-carbon manufacturing pathway. Our work is developing the technical and commercial basis for that opportunity through the evaluation of advanced biomass gasification and combined heat and power integration.
Forest products manufacturing creates valuable products alongside residual wood streams. Where those residues cannot be retained in suitable material applications, recovering their energy provides another productive use. At the same time, industrial operations need electricity and heat at the right quality, quantity and time to support production.
Bringing those needs together requires more than selecting a gasifier. Moisture, particle size, contaminants, seasonal availability and existing uses influence how much wood is genuinely available and how consistently it can support energy production; a wet tonne of residue is not equivalent to a dry tonne in an energy model. The energy user matters just as much as the fuel: heat has commercial value when an operation can use it at the required temperature or pressure, and electricity has value only after the plant’s own consumption is deducted and connection arrangements are assessed. The DFS provides the framework for evaluating those relationships before major capital commitments are made.
An integrated pathway from residual wood to useful energy. The process under evaluation uses controlled, oxygen-limited gasification to convert suitable wood residues into a combustible syngas. In a heat-and-power configuration, that gas is combusted under controlled conditions, with the resulting thermal energy recovered in a boiler; steam can drive a turbine-generator, while suitable heat is recovered for industrial use. Fuel preparation, controlled feeding, emissions treatment and ash management complete the system. This staged approach allows fuel conversion and energy recovery to be integrated around a defined industrial duty, with the final equipment arrangement and heat-and-power balance depending on the DFS findings.
Designing around the operation. Our development approach connects the feedstock, conversion equipment and energy users as one system. Potential thermal applications in the forest products sector include timber drying and other process-heating duties, with suitability depending on the actual heat demand, distribution distances and operating profile. The objective is a configuration that makes useful energy available where it has the greatest operational value, including the trade-off between electricity generation and heat recovery, together with the effect of drying requirements and auxiliary equipment on net output.
Turning an opportunity into an investment decision. The feasibility assessment establishes the available feedstock envelope, a study-level mass and energy balance, the integration requirements and the basis for capital and operating costs, together with environmental approvals, utilities, maintenance, operating capability and the route into subsequent engineering. Sensitivity analysis is essential: changes in feedstock moisture, annual availability, energy prices, usable heat demand and plant operating hours can materially change the investment case, and evaluating those variables establishes what the project must deliver to justify progression into Front-End Engineering Design and an eventual investment decision.
More value from the wood already being processed. Energy recovery extends the productive use of eligible residual wood after suitable material uses have been considered. The opportunity starts with the available waste stream and its current destination, allowing the project to assess additional value without assuming every residue is unused or destined for landfill.
Electricity and heat returned to industry. Combined heat and power creates the opportunity to use both electrical and thermal output. Where a steady heat demand exists, recovering useful heat can increase the share of feedstock energy put to productive work and improve the economics of the overall system.
A pathway to lower-carbon production. Replacing fossil-derived energy with energy from eligible biomass residues could reduce the emissions associated with manufacturing. The DFS must test that benefit against the existing energy supply and residue-management baseline, including feedstock sourcing, transport, preparation, auxiliary fuels and conversion efficiency; biogenic carbon emissions remain part of the assessment, and the lower-carbon outcome must be demonstrated for the complete system.
Greater control over an essential input. Using an available residual stream for on-site energy could reduce exposure to purchased energy and create a closer connection between production and fuel supply. Reliable operation still requires appropriate maintenance, backup arrangements and a sound feedstock plan, and any islanded operating capability would need separate assessment and design.
A stronger basis for environmental performance. Controlled conversion, suitable flue-gas treatment and monitoring are integral to evaluating a clean-energy project. Ash must be characterised and managed through an authorised route, with beneficial use considered only where its properties and applicable requirements support it.
Developing the basis for deployment. The project is at the DFS development stage. The intended outcome is a defensible basis for deciding whether, how and at what scale the proposed biomass energy system should proceed; plant capacity, annual energy production, carbon savings and financial returns will depend on that assessment. The significance is already clear: a major forest products business is examining how its wood waste could become part of its own energy solution, and Klean’s role is to connect that opportunity to the technology, equipment integration and project-development decisions required to make it deliverable.
1. Size the project around usable energy demand.
For an electricity-and-heat opportunity, a dependable thermal user can be central to value. Evaluate the demand profile and heat quality before fixing generating capacity; output that cannot be used does not carry the same value as energy that displaces a real cost.
2. Value the residue on a usable-fuel basis.
Moisture, preparation, existing outlets and seasonal supply determine what a wood-waste stream can contribute. Establish the dependable quantity, energy content and delivered cost before using headline tonnage to support an investment model.
3. Build the carbon case alongside the financial case.
The proposed benefit depends on which energy and residue-management practices are displaced. Assess those baselines together so the project can substantiate its environmental contribution while testing whether the energy savings support the investment.
These takeaways highlight selected lessons from this case study, not an exhaustive account. Klean brings deeper technical expertise and commercial insight to each project through tailored engagements.
If your operation produces wood residues while purchasing electricity and process heat, the consequential question is how much useful energy that material could supply — and at what whole-project cost. Klean brings technology development, equipment and systems-integration experience to that assessment.
A defined, paid DFS can establish the fuel basis, evaluate the appropriate conversion and heat-recovery configuration, and test the commercial case before progression into FEED. Earlier-stage opportunities can begin with project evaluation and a Detailed Equipment Quotation (DEQ) to establish the initial scope.
