PhD, Chemical Process Systems Engineer | Process Simulation, Life Cycle Assessment, TEA & Sustainable Process Assessment

I am a chemical and process systems engineer specialising in the environmental and techno-economic assessment of emerging chemical, recycling, and circular technologies.

• Aspen Plus
• Chemieingenieur5 J.
• Life cycle analysis
• Process design
• Process optimization
• Process simulation
• Python
• Recycling / Abfallverwertung
• Sustainability assessment
• Techno economic analysis

I combine process engineering, life cycle assessment, and computational modelling to help R&D teams, technology developers, and engineering organisations determine whether a new process is environmentally credible, technically feasible, and economically viable before major scale-up and investment decisions are made.

My expertise includes:
• Aspen Plus process simulation and conceptual process design
• automated Python-based modelling workflows
• detailed mass and energy balances
• process-specific life cycle inventory development
• comparative and parametric life cycle assessment
• techno-economic and scale-up assessment
• sensitivity and Monte Carlo uncertainty analysis
• environmental hotspot and break-even analysis
• process-route and technology benchmarking
• customised Python and Excel decision-support models
• technical literature reviews and scientific reporting

Rather than producing a single static environmental footprint, I develop transparent and adaptable assessment models that show how process yields, energy demand, raw materials, recovery systems, operating conditions, and scale-up assumptions influence environmental performance and economic viability.

My research has focused particularly on the chemical and solvent-based recycling of polymers. As first author of a study published in Environmental Science & Technology, I developed an automated Python-Aspen Plus-LCA workflow to compare four chemical recycling routes for nylon 6 under changing process conditions and uncertain feedstock compositions. The work identified the technical conditions and process parameters that determine when different recycling routes become environmentally advantageous.

I also led a techno-economic assessment of nylon-6 chemical recycling published in the Chemical Engineering Journal and contributed to research on ionic-liquid-based recycling, solvent-based polymer separation, and sustainable separation processes.

I support clients in comparing alternative technologies, evaluating environmental and economic scale-up risks, identifying critical process improvements, and developing robust technical evidence for R&D, investment, and technology-development decisions.

My objective is not simply to calculate environmental impacts. I identify the process parameters, technology choices, and scale-up conditions that determine whether a technology can succeed, and where development efforts can create the greatest environmental and economic value.
