Life Cycle Inventory Assessment as a Sustainable Chemistry and Engineering Education Tool

Abstract

Chemists and chemical engineers are involved in and responsible for the life of a product from the discovery stage to manufacturing, market introduction, and end of life. They participate in and contribute to all segments of the supply chain, from cradle to grave. In the industrial sector, they work hand in hand with other professionals in engineering, business, intellectual property, and environmental safety and health. To better prepare students to understand industry-focused grand challenges and contribute to the long-term sustainability of the enterprise, we designed a course for advanced undergraduate and graduate students in the Schools of Chemistry & Biochemistry and Chemical & Biomolecular Engineering at the Georgia Institute of Technology. The pilot class of 26 students was introduced to chemical manufacturing, the eight sustainability grand challenges, intellectual property, regulatory and registration, and process hazard and safety. Invited speakers from industries such as Albemarle, BASF, Dow, ExxonMobil, GSK, Solvay, and PepsiCo presented their companies’ approach to sustainability. Life cycle inventory (LCI) assessment of an existing product in the market was the main thrust of course, whereby student teams were charged to develop a virtual manufacturing process based on their review of patented literature. The groups completed nine LCI assessment projects, and by applying mass metrics and GC&E principles, they offered recommendations for rendering the processes more sustainable. This perspective presents the course objectives, approach, LCI methodology, results, conclusions, and lessons learned.

A consolidated road map for economically gainful efficient utilization of agro‐wastes for eco‐friendly products

“…It is necessary to make products that are affordable . An eco‐efficiency and footprint analysis, and lifecycle assessment of each product is necessary to consider issues of biodegradability, recyclability, toxicity, etc . A product should satisfy a wide variety of interests – business, the public, farmers, wildlife, those who are concerned about the environment, etc.…”

Safety, Economic, and Environmental Optimization Applied to Three Processes for the Production of Solar-Grade Silicon

“…In past decade, significant advances have been achived in identification and understanding of the problems related to the safety and environmental impact in industries. Chemical engineers and chemists are involved in and responsible for the life of a product from the discovery stage to manufacturing, safety, market introduction, and end of life . Nowadays, many products and processes are already designed considering safety and environmental issues.…”

“…Chemical engineers and chemists are involved in and responsible for the life of a product from the discovery stage to manufacturing, safety, market introduction, and end of life. 3 Nowadays, many products and processes are already designed considering safety and environmental issues. Nevertheless, there is still much to be done in novel processes and products, since the safe and clean engineering practice has shown its potential for being applied more broadly, deeper and in a more systematic way.…”

Beyond the Deficit Model: Organic Chemistry Educators’ Beliefs and Practices about Teaching Green and Sustainable Chemistry

“…Mahaffy and coauthors offer a vision for integrating green and sustainable chemistry into the general chemistry curriculum, and the next few years will reveal the impacts of these reforms. The concepts of green and sustainable chemistry are also commonly discussed in relation to professional development, or progressive ideas such as social justice . Despite evidence of a robust field of research and academic interest, implementing major change to science curricula remains a slow-moving process. , The recent increase publications on “green chemistry education” highlights an active and ongoing pursuit of resources, pedagogical approaches, and educational frameworks for centering these topics in post-secondary courses .…”
