Grading Type:
Prerequisite Modules:
Rationale and Purpose of the Module:
To inform the student of the need to design and manufacture products in an environmentally sustainable manner.
To illustrate the use of life cycle analysis software to ensure that the lowest impact material selection, manufacturing processes etc. are adhered to.
To identify the various recycling/recovery processes available to ensure that the student designs a product with these solutions in mind at end of life.
To identify key alternatives to existing fossil fuels in energy creation and thereby help promote a more sustainable manufacturing environment.
Syllabus:
Design for Environment
Strategies, tools, key fundamentals such as design for dematerialisation, design for product recovery and design for capital protection and renewal.
Sustainable Manufacturing
Alternative energy supplies, solar, wind, geothermal, alternatives to oil such as bio-diesel, gaining energy from recycling materials or waste e.g. incineration, pyrolysis.
Material properties, material property charts, material selection, case studies.
Recycling Technologies
Magnetic separation, shredding, eddy current separation, infra red separation, examination of waste streams, destruction disassembly versus step by step disassembly. Design obstacles to disassembly, design techniques to encourage disassembly and thereby encourage effective recycling/recovery.
Lifecycle Assessment
Overview of total product life cycle, from raw material selection to transport to manufacturing processes and systems to packaging and the impact individual decisions regarding the product have on the environment. Using LCA software to calculate the cost to the environment.
Reverse Engineering
Techniques, systems of approaching systematic reverse engineering to enable design for the environment and to learn from previous mistakes. Product redesign can take the form of incremental or radical changes.
Legislation
WEEE directive, RoHS directive, ISO 14062 - environmental aspects to product design, ISO 9000.
Design for End of Life
Examination of fastening technology, standardisation of techniques, placement of access points, location of high value/hazardous materials.
Learning Outcomes:
Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)
On successful completion of this module students will be able to:
1. Develop a life cycle analysis of a product detailing both the cost to the environment and the cost to the manufacture of specific design features .
2. Understand the implications of design changes on the manufacture of a product
3. Evaluate and consider effective alternatives to fossil fuels in energy creation.
4. Reverse engineer and then redesign (incremental or radical) a product from an environmentally sustainable perspective.
5. Develop and design a product with en end of life perspective to ensure effective and efficient and therefore economic recycling and recovery.
6. Minimise wastage within the manufacturing process to ensure a sustainable product.
Affective (Attitudes and Values)
On successful completion of this module students will be able to:
1. Appreciation for the environment and the need to design products with End of Life considerations. Appreciation for use of alternative energy supplies within the manufacturing process.
Psychomotor (Physical Skills)
On successful completion of this module students will be able to:
1. Project work - fabrication techniques (turning, milling), automation of system.
How the Module will be Taught and what will be the Learning Experiences of the Students:
The module will be delivered in a formal lecture setting complimented with laboratory practical sessions. A number of site visits to recycling plants may be included.
