Reducing waste through better design and simple repairs

Reducing waste through better design and simple repairs

Making simple repairs could save the UK could save millions of pounds by replacing fuses or plugs rather than throwing away perfectly reusable microwaves with brand new ones.

Published in the Journal of Cleaner Production, University of Manchester PhD student Azadeh Dindarian and her team examined 189 microwaves at refuse centres and found that 54% of microwaves in a single year appeared to be disposed of simply for cosmetic reasons or because they had minor faults, and that 85% could be safely repaired. They have also found that some simple changes in design could prevent some of these faults from happening altogether.

Finding ways to re-use discarded microwaves could help to prevent thousands of tonnes of waste every year. These devices are often shredded in specialist recycling centres which are not often capable of retrieving valuable materials.

Azadeh, who was shortlisted to present her research at the House of Commons, believes product reuse is essential to reduce current levels of waste and create a more sustainable economy.

Barry Sheerman, MP for Huddersfield and Chairman of policy connect, added: "The excellent and compelling work carried out by the School of Electrical and Electronic Engineering is persuasive in demonstrating that many microwaves that are discarded could be reused or remanufactured, saving money, and crucially, natural resources."

Azadeh, 29, who is in the final year of her PhD in Electrical and Electronic Engineering, was supervised on her project by Professor Andrew Gibson, and Dr Joao Quariguasi Frota Neto. The researchers now plan to extend the research to include washing machines, fridges and other devices to reveal the full scale of appliance waste in the UK. Azadeh said: "Our research shows that the vast majority of dumped microwaves and other white goods could easily be re-used, however unwanted functional products tend to end up being wasted rather than being disposed of through alternative routes."
