In the last couple of years, we have not ceased to be amazed by the source material from which film or paper for packaging are ultimately obtained. Seaweed, bamboo, fallen leaves, rice waste, mushrooms... You can't remember them all. And now it's the turn of onion peels.

The HUID company noticed that a large amount of onion peels are thrown away every week. Which has antimicrobial properties. This means that packaging made from them could potentially extend the shelf life of perishable products. What happened next was apparently a matter of technology.

Cellulose is extracted from onion skins and then combined into a biopolymer mixture. The result is a film that is as strong as plastic solutions. And of course, where there is cellulose, there is cardboard for packaging.

Thus, there are two prototypes of packaging materials from onion peels: flexible film Cellofil and Pyber, which the company compares to cardboard. And while the film is still in development, the company plans to launch cardboard solutions by mid-2025. It is clear that both options are declared as biodegradable at home.

And just recently, HUID received additional funding of £170,000, confirming interest in its development from outside investors.
