Reducing Plastic Pollution

CuanTec have developed the World's first clear Chitosan films with natural antimicrobial properties to replace single-use plastics. This is only possible due to our propriety methods of extraction that use less energy and have zero waste.

Saving Food Waste

Chitosan has antimicrobial properties. By using this as a key ingredient in our packaging, we can extend the shelf life of fresh seafood, allowing your fresh food to last longer.

Circular Economy

We have carefully designed our methods to be a zero waste, circular process. We use waste from another industry as our raw material and ensure any by-products are repurposed.



We are a biotechnology company based in Oban, on the west coast of Scotland.


We’ve developed a gentle, biological method to extract the natural product chitin from different sources of waste from the food industry.


Chitin and its derivative, chitosan, have fantastic properties.  We aim to have a zero-waste, circular business and that starts by using waste shells from the seafood industry to create a compostable, antimicrobial material that can replace single use plastic packaging and extend the shelf life of fresh food.
