    Broad and complex challenges associated with sustainability of materials. Aspects of product lifecycle related to material selection and use (processing, production, design, end-of-life).

    Ever wondered what makes a material sustainable, what part you play towards a sustainable future, or why metals should be recycled? MATS 204 takes you on a journey through the lifecycle of everyday objects and the materials they are made of; from the impacts of extracting raw materials to what happens at the end of their life and all the bits in between. Learn what to treasure about materials and how not to trash them! Be proactive about sustainability and study over the summer without having to be on campus.

    Feedback from previous years:

    "It is nice to learn about something that is completely different to my degree."

    "So interesting and refreshingly different to the kind of learning I am used to at university!"

    "It has definitely been my favourite paper that I have taken through my university studies."

    "Really enjoying the subject and classes… and have learnt so much."

    "I absolutely loved the course and how it made me think differently as a consumer."

    Paper Structure

    This paper is structured around a lifecycle and will address the following issues:

    1. National and international principles of sustainability: principles of sustainability, legislation, certification models and assessment tools
    2. Resources (extraction and production): extraction of raw materials waste, pollution, energy use
    3. Strategies for design and manufacturing: materials and methods of manufacturing
    4. Consumer role and ethical considerations: the role of the consumer in use of a product and ethical considerations for sustainability
