Description: There are many sound reasons why environmental issues should be considered in the design and product development process. They help us meet customer and legislative requirements. They put us in a stronger competitive and commercial position. They play a major part in ensuring we maintain innovative credibility.
But most of all, they help us achieve our ambition of reducing the overall environmental impact of our products across their lifecycle. Here we want to demonstrate the environmental impacts of bearings in terms of embodied energy (energy consumed during production), carbon footprint, and eco-indicators of bearing range for a variety of application. New bearings designed on the concept of green design include seal technologies (hard seal coatings and surface design); light-weight parts (polymers), and ‘lub-for-life” thin film lubrication, which makes re-lubrication unnecessary throughout a bearing’s lifespan. An estimated 50 billion bearings are in use at any time and reduction in energy consumption by a 30-70% depending on the type of use can be tremendous savings in energy. It would consequently reduce carbon dioxide emissions in atmosphere as well as savings in resources and money. It will also lead to enormous reduction in the lubricant disposal. Ships trading in the world’s oceans and seas can eliminate both operational and accidental stem tube oil pollution, while also reducing their operating costs.
In this age of Industry 4.0, the design principles and practice must include the nature of industry today not 100 years old practices. The topics included are most of the concerns and ideas discussed briefly above.
The lecture and presentation should attract experts and professional from industry as well as academia. I have noticed in past instructors teaching such courses and, researchers including Ph.D. candidates are interested in such topics and lectures.
Topics:
- Sustainability and Ecological Considerations in Engineering Product Development.
- Mathematical techniques used in sustainable optimal design; including Life Cycle Analysis (LCA) for engineering design.
- Sustainable Consideration and Mathematics of Recyclability, Reuse, and Circular Economy
- Practical and useful applications of sustainability in green power generation, disassembly and recycling, and time elements in assembly and disassembly.
- Ecological considerations and sustainability in manufacturing.
- Green design and manufacture of sustainable products in the age of Industry 4.0
