Reference excerpt

Michael Shaver is Professor of Polymer Science in the Department of Materials at the University of Manchester, Director of the Sustainable Materials Innovation (SMI) Hub, and a Fellow of the Royal Society of Chemistry and the Institute of Materials, Minerals and Mining (IOM3). He is a polymer scientist specialising in the sustainability and circularity of plastics, and his research addresses mechanical, chemical and enzymatic recycling of plastics, sustainable polymer design, and systems-level approaches to materials circularity.

Education Shaver completed his Bachelor of Science in Chemistry at Mount Allison University in 1999. He then earned a PhD in Chemistry from the University of British Columbia in 2005, with a dissertation entitled Small Molecule Activation by Diamidophosphine Complexes of Vanadium, Niobium and Tantalum. He subsequently undertook an NSERC Postdoctoral Fellowship at Imperial College London.

Career Shaver began his academic career at the University of Prince Edward Island (UPEI), where he was appointed Assistant Professor of Inorganic Chemistry in 2007. He rose to full Research Professor and held the UPEI Research Chair in Green Materials Chemistry from 2009. In 2012, he moved to the University of Edinburgh as a Chancellor's Fellow in the School of Chemistry, an early-career fellowship. He was subsequently promoted, becoming Professor of Polymer Chemistry in August 2017, and during his time at Edinburgh served as Head of the Graduate School in the School of Chemistry from 2014. He joined the University of Manchester as Professor of Polymer Science in January 2019, based in the Department of Materials within the School of Natural Sciences. He became Director of the Sustainable Materials Innovation Hub (SMI Hub) in July 2020, and was the inaugural Director of Sustainable Futures, the university's platform for interdisciplinary environmental sustainability research, from 2021. In 2023, he was appointed the Vita Group / Royal Academy of Engineering Research Chair in Sustainable Automotive Polymers.

Research Part of his research concerns the degradation of plastics during mechanical recycling, where used plastic is sorted, washed, melted and re-formed. Another 2024 study published in Nature Communications developed methods for quantifying and tracking the chemical degradation of high-density polyethylene (HDPE) through mechanical recycling cycling. A further topic has been developing methods to quantify the proportion of recycled content in plastic products and packaging. Shaver and his group have also worked on chemical recycling, which breaks down polymer chains back to their monomer constituents for re-polymerisation. Michael Shaver has been an active contributor to plastics policy in the UK and internationally.

Honours and recognition Fellow of the Royal Society of Chemistry (FRSC), elected 2017 Fellow of the Institute of Materials, Minerals and Mining (FIMMM), elected 2019 Vita Group / Royal Academy of Engineering Research Chair in Sustainable Automotive Polymers, 2023-2028 Institute of Materials, Minerals and Mining Swinburne Medal, 2024, awarded for outstanding contribution to the advancement and knowledge of the science, engineering or technology of plastics

Worked examples

Example 1 — a first encounter with Michael Shaver

Start with the simplest possible case. Write down what Michael Shaver claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Michael Shaver before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Michael Shaver ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Michael Shaver

In research: Michael Shaver appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Michael Shaver in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Michael Shaver is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century British chemists, 21st-century Canadian chemists, Academics of the University of Edinburgh, so understanding it makes those chapters shorter.
In everyday life: Look for Michael Shaver outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
