Abstract

Integrating waste minimization metrics with Life Cycle Assessment (LCA) enhances sustainability evaluations in chemical manufacturing. This study proposes a hybrid framework combining ISO 14040/14044-compliant LCA with green chemistry indicators such as E-factor, Process Mass Intensity (PMI), and Atom Economy to assess the environmental performance of a chemical process. The methodology employs a cradle-to-gate system boundary and utilizes both primary inventory data and secondary sources including Ecoinvent and EF 3.1 databases. Waste metrics are derived from life cycle inventory data, and environmental impacts are assessed using TRACI 2.1 and EF 3.1 methods. The results demonstrate that integrating waste metrics with LCA offers deeper insights into process sustainability. A process characterized by an E-factor of 2.20, PMI of 5.80, and Atom Economy of 78.0% showed significant material efficiency but also revealed trade-offs between solvent recovery and energy demand. The Life Cycle Impact Assessment (LCIA) reported a Global Warming Potential (GWP) of 2.45 kg CO₂-eq and a water footprint of 2.50 m³ per kg of product, indicating the influence of upstream inputs and energy sources. This dual-framework approach improves decision-making in process design by aligning operational efficiency with environmental outcomes. It facilitates the identification of hotspots, supports targeted optimization, and enhances transparency in sustainability reporting. The findings underscore the value of integrating LCA and green chemistry metrics to advance environmentally responsible chemical manufacturing.

Abstract

Chemical manufacturing is under increasing pressure to reduce its environmental footprint. Life Cycle Assessment (LCA), as defined by ISO 14040/14044, is an established method for evaluating such impacts. This study aims to integrate LCA with quantitative waste minimization metrics Process Mass Intensity (PMI) and E-Factor to evaluate the environmental benefits of process redesign. Two chemical process scenarios (baseline and improved) were assessed using a cradle-to-gate LCA approach. TRACI 2.1 and USEtox were employed to evaluate environmental impacts across categories such as climate change, human toxicity, and water use. PMI and E-Factor were calculated from foreground process data, and background inventory was sourced from the ecoinvent database. Allocation was based on mass, and uncertainty was assessed via Monte Carlo simulations and sensitivity analysis. The improved process demonstrated a 33% reduction in PMI and a 50% decrease in E-Factor, driven by solvent recovery and energy optimization strategies. Climate change impact dropped from 15.0 to 10.2 kg CO2-eq, while human toxicity and water footprint also saw substantial improvements. LCA findings provided actionable insights for process redesign, revealing that targeted waste minimization enhances overall environmental performance. While energy demands initially rose, optimization and heat integration neutralized trade-offs, supporting more sustainable operations. Integrating LCA with PMI and E-Factor offers a robust, standardized framework for evaluating waste minimization in chemical processes. This approach supports environmentally sound decision-making and can guide future innovations in green chemistry and sustainable manufacturing.

Abstract

Uncertainty in energy markets and emission factors presents a significant challenge to sustainable manufacturing. This study aims to develop a simulation-based sensitivity framework to assess how variability in fossil fuel prices and emission coefficients impacts sustainability outcomes. Using One-At-a-Time (OAT), Tornado analysis, and Monte Carlo simulations, the study evaluates the influence of energy prices (oil, coal, natural gas) and emission factors (CO₂ per GJ for various fuels) on manufacturing sustainability. The framework incorporates real-world parameter ranges and applies probabilistic modeling to capture compound uncertainties. Sensitivity analysis reveals that coal and oil prices are the most influential variables in cost-driven assessments, while emission factor variation particularly for coal and diesel introduces significant uncertainty in carbon accounting. Monte Carlo simulations, run over 10,000 iterations, show wide variability in sustainability scores, underscoring the need for risk-informed planning. Tornado diagrams visually rank variable importance, facilitating policy and operational prioritization. Contextual influences, such as national energy mixes and regulatory environments, further shape parameter sensitivity. Findings demonstrate the strategic value of compound modeling in subsidy targeting, supply chain planning, and compliance forecasting. This study contributes a practical, adaptable framework for sustainability modeling under uncertainty. By quantifying the probabilistic impact of volatile energy and emissions data, it enhances the credibility and utility of manufacturing assessments. The framework supports policymakers and industry leaders in designing robust, context-specific strategies for sustainable transitions.
