These include a glass container that uses water channels to keep its contents from oxidising, and a loose-leaf teapot to replace single-use bags.

Different coloured scales on the side of each vial help the pharmacist fill in the right doses, while the lid is made from recyclable plastic to create an airtight seal.

Another project intent on repurposing waste comes from Gao Ziyu, who designed a fishbowl that doubles up as a watering can.

As food packaging is a major contributor to the plastic waste crisis, various projects proposed more sustainable alternatives.

The polymers in plastic, on the other hand, degrade a little every time they are recycled, meaning they need to be mixed with new, virgin plastic to remain viable.

Jaxon Pope created a series of glass vials that could be used as an alternative to the throwaway blister packs in which medication is commonly sold.

Another student encased coloured glass offcuts – which are harder to recycle due to the chemicals used to dye them – within clear glass to create decorative, Terrazzo-like tiles.

Julius Nobling, meanwhile, created a series of vases in different shapes and sizes, to draw attention to the little-known fact that various vegetables can easily be re-grown at home with nothing but scraps and stumps that would otherwise have gone to waste.

Others turned their attention to the personal care industry, designing packaging that would facilitate a keep-and-refill system. Customers would hold on to their glass containers and top up everything from make-up to cleaning products in the shop.

The tiles would be attached to the wall using a backplate. Its internal pattern allows wires to be neatly organised before they are safely enclosed behind a removable front face.

In this way, the potassium, phosphorous and nitrogen that build up in the water over time aren't flushed down the drain when the water gets changed, but instead used to help plants grow.

In the system Pope is proposing, pharmacies would receive medication in bulk before portioning it out into these vials according to the needs of each customer.

Rob Parker, Director at Grant Thornton said: “We are very pleased to have completed a going concern sale of the business, which secures the continued employment for a loyal workforce in these challenging economic times.

Reusable glass vials for pills can replace disposable blister packs, while glass tiles could replace the plastic used to insulate wires.

"Glass has two main selling points in a cyclical system: its longevity and its recyclability," said Lund University student Riccardo Centazzo."It is an impermeable material with high corrosion and temperature resistance that can also be exceptionally hard."

"Used vials are sent to a cleaning facility to be industrially cleaned and a vial that is considered too scratched can be sent back to the manufacturer to be melted down and used in the production of new vials."

The Joint Administrators were advised on the transaction by the Squire Patton Boggs team and Hilco Valuation Services, in Birmingham. S M Automotive Division Limited was advised on the transaction by MFG Solicitors in Worcestershire.

Centazzo's project is a system of tiles that makes use of the insulating properties of glass to replace the vast amount of mixed plastics normally used to encase electrical wires in the home.

"I created a thin, long vase for things like leeks and spring onions so that they could grow straight," he explained. "The round one is meant for herbs like basil or coriander and has a small opening so that the cutting can fit easily without falling."

"By moving the wiring from inside the walls to their surface, they are easier to access for maintenance or modification without having to damage walls or replace the whole system. If a house is demolished, the tiles can easily be reused or recycled."
