Fraunhofer FFB and RWTH Aachen University have developed a model for comparing lithium-ion battery-recycling processes by economics and environmental impact. It tracks material flows and accounts for factors including plant utilization and regional electricity mixes; the developers say the framework may be expanded to cover more battery chemistries and regulatory scenarios.
Fraunhofer FFB and RWTH Aachen University have developed a modular model that compares lithium-ion battery-recycling processes by their costs and CO₂ emissions. The tool lets users build process chains and account for variables such as battery composition, plant utilization and regional electricity supply, giving recyclers and manufacturers a common framework for evaluating technology choices.
The model, called the Modular Lifecycle Tool, breaks the recycling chain into areas, process steps and technologies. Users can assemble customized chains from a database of process information, set inputs such as battery composition and material throughput, and examine how choices at one stage affect later steps. For example, the model can compare alternative shredding methods and assess their downstream effects.
Calculations connect material flows with economic and environmental indicators. The inputs described include energy use, emissions, operating and investment costs, revenue from recovered materials and disposal costs. Users can also account for regional electricity mixes, labor costs and plant utilization. Changing throughput, separation efficiency or recovery rates shows how those adjustments affect subsequent stages, costs and emissions, according to the report.
The tool is intended for recycling companies, technology providers and battery manufacturers, and can be used to examine existing processes or assess new technologies. Its development formed part of a consortium study with partners from recycling, plant engineering and consulting. The source report does not provide a public release date, access terms or independent validation results.
Comparing Recycling Costs and Emissions
The model addresses a practical challenge for an industry weighing different recycling routes: a process that performs well at one stage may affect the quality of recovered material, the work needed later, and the overall economics. By linking steps across a chain, the tool is designed to show where costs or emissions arise, rather than treating each technology in isolation.
Its location and utilization inputs also matter to investment decisions. Electricity sources and labor costs vary by region, while the amount of material passing through a facility can change its operating economics. Comparing those assumptions could help companies test whether a proposed process chain remains viable under different operating scenarios. The model is an evaluation framework, however; the report does not establish that it will improve recycling profitability or reduce emissions in actual facilities.
The economic backdrop is difficult. A study from the EU research project Safeloop, cited in the report, found that under the conditions it examined, recycling lithium-ion batteries in Europe produced an average loss of about €1.90 per kilogram of battery pack. The finding is specific to that study’s examined conditions, not a universal estimate for all plants or recycling routes. Safeloop identified hazardous-goods transport, disassembly and uncertainty over material recovery as key cost drivers.

A Chain-Level View of Recycling
Battery recycling involves multiple linked operations, and the available methods can differ in energy demand and recovery rates. The report says early-stage decisions can influence material quality and the effort required in later processing. A comparison that includes those connections may offer a fuller view than an assessment of a single machine or process step.
The Fraunhofer-RWTH model represents those operations as a modular process chain. Users can alter individual parameters and see their modeled effects downstream. This makes it possible to explore scenarios for scaling recycling industrially, though scenario outputs depend on the data and assumptions entered. The developers’ stated aim, as reported by electrive.com, is to put different recycling concepts on a common basis for technological and strategic decisions.
The framework is not described as a new recycling technology or a facility. It is a calculation and comparison tool intended to support decisions about processes. The source says it was produced through a consortium study involving industry and consulting partners, but does not name those partners or provide details on the model’s software format.
“With this tool, we aim to make different recycling concepts comparable on a common basis and thereby create a robust foundation for technological and strategic decisions.”

Questions on Data and Availability
The source report does not say when the tool will be available, who will be able to use it, or whether access will be commercial, public or limited to project partners. It also provides no test results comparing model predictions with operating data from recycling facilities, so the tool’s accuracy and practical performance cannot be judged from the report alone.
The scope of the current database is also not specified in detail. The developers say the framework is expected to expand to include additional battery chemistries, regional datasets and regulatory scenarios, indicating those areas are not yet fully covered. The report does not state which chemistries, regions or regulations are currently represented, or when the planned additions may be completed.
Finally, the Safeloop loss estimate applies to the conditions examined in that project. The report does not give enough detail here to generalize the figure across different battery types, plant scales, locations or market prices for recovered materials. Those factors may affect whether a particular recycling chain is economically viable.
Planned Model Expansions
The developers plan to extend the evaluation framework with more battery chemistries, region-specific datasets and regulatory scenarios. The source report gives no schedule for those additions. It also does not identify a next public milestone, such as a software release, pilot deployment or independent review.
For now, the reported next step is further development of the model’s coverage. Its potential usefulness will depend on the availability and quality of input data, how well modeled results reflect real facilities, and whether intended users can access it. No adoption figures or decisions by recycling companies were reported.
Key Questions
What did Fraunhofer FFB and RWTH Aachen develop?
They developed the Modular Lifecycle Tool, a model for evaluating lithium-ion battery-recycling process chains by cost and environmental impact.
What factors can the model include?
According to the report, it can account for material throughput and battery composition, energy use, CO₂ emissions, investment and operating costs, recovered-material revenue, disposal costs, regional electricity mixes, labor costs and plant utilization.
Does the model prove that battery recycling is profitable?
No. It is described as a tool for comparing processes and scenarios, not as evidence that recycling is profitable. A cited Safeloop study found an average loss of about €1.90 per kilogram of battery pack under the conditions it examined in Europe.
When will companies be able to use the tool?
The source report does not give an availability date, access terms or a public release plan.
What additions are planned for the model?
The evaluation framework is expected to be expanded with additional battery chemistries, regional datasets and regulatory scenarios. No timeline was reported.
