94274 - Raw Materials

Learning outcomes

At the end of the course the student will be aware of the criticiy of feedstock supply of some raw materials, bot organic or inorganic. The student will know how to design new products and processes for the improvment of recyclability and reuse. She/he will be able to use Life Cycle Assessment as most important tool for general and environmental evaluation of chemicals in the perspective of circular economy. The studente is expected to be able to: 1. contributr to design products and processes that are intrinsecally suitable for a smart recycling of the components and materials; 2. to propose alternatives to the critical raw materials now in great use, or improve their recycle; 3. to exploit the instuments of LCA for the assessment of improvements achievable.

Course contents

This CU is composed of three modules which are taught autonomously:

(1) Life Cycle Assessment:

Life Cycle Assessment (LCA) is an internationally standardized methodology to evaluate the eco-sustainability of processes and products over their life-cycle, supporting comparisons between alternatives and providing a rank of environmental priorities in the investigated systems. It is used as a quantitative basis for decision-making in industry, academia and policy contexts.

(2) Sustainability and Circularity of Material Flows

In this module students learn to apply material flow analysis to important raw materials used in the chemical industry. These will be used to develop indicators for circularity and sustainability of chemical processes.

(3) Design for Recycling

In design for recycling, the suitability of a product design for recycling is considered, with products designed for easy disassembly and the use of compatible raw materials. This module covers the concept, rules and guidelines of design for recycling.

Readings/Bibliography

Lecture notes and selected papers will be available for students.

Recommended reading:

• ISO 14040 and ISO 14044
• Brunner, P.H.; Rechberger, H. “Practical Handbook of Material Flow Analysis”. Lewis Publisher, 2004.
• Industrial Ecology and Sustainability, by Thomas E. Graedel (Author), Matthew J. Eckelman (Author), 2023 World Scientific Pub Co Inc

Teaching methods

Expositive lectures presenting the basic concepts and state of the art in the field, and exercise seminars.

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 on Health and Safety online.

Assessment methods

Students could be evaluated by written tests, multiple choice questions, group reports on a given case study, or individual presentations to class.

Teaching tools

The course will be taught with the aid of computer support for the projection of text and images. The slides will be left available to the students, usually uploaded on the course platform.
