About Us

Bio-Trimmings believes in crafting for the future of design and sustainability using science. By making beautiful jewellery & accessories from inedible food compounds, mainly from fruit & vegetable components, our team are passionate about making eco-friendly, re-purposed materials to make a powerful, beautiful, fashion statement.

You will find that most of our designs feature our durable and eco-friendly Bio-Gems, which are handmade in our London studio. Each one is individually handcrafted to create a beautiful, statement piece that promotes the endless possibilities and pushes boundaries of what can be achieved within fashion, from typically discarded materials.

Presented with recycled sterling silver, using materials sourced from UK suppliers, positive, ethical and sustainable practice are central to our brand ethos.

We are always finding new ways to define innovation, forward-thinking design ideas with thought and care.

About The Designer

British-born fashion designer, Hoyan Ip is the founder of Bio-Trimmings. It is the result of a passion for jewellery-making and a desire to prompt positive change in the fashion industry. It is her connection with the vibrant and fast-paced world of fashion, alongside a love of art, architecture, nature and contemporary culture, that serves as constant sources of inspiration for the brand.

Bio-Trimmings was founded in 2012, was first showcased during London Fashion Week as a collection of unique, sustainable, fashion trimmings such as buttons and buckles all handcrafted from inedible food extracts. It soon captured the attention of international press and industry interest with the innovative concept of creating unique, fashion products from domestic food waste collected from her local community and transformed into beautiful sustainable products. Most importantly, it shows how interlinking strong, scientific knowledge and food research with design makes an unusual and powerful statement promoting future sustainability by re-using wasted food to create luxury products that are both beautiful to look at and hold ethical meaning and imagination.

In addition to the Bio-Trimmings collection, Hoyan Ip has developed more to the range including unique pieces of jewellery, handbags, accessories and bouquets to add to the collection of products made from wasted food which have the advantages of being mould-free, odour-free and meat-free as well as being a statement fashion piece.


Sustainability to us is about meeting the current needs without compromising the ability of future generations to meet their needs.

Food waste refers to food appropriate for human consumption being discarded, whether or not after it is kept beyond its expiry date or left to spoil. Often this is because food has spoiled but it can be for other reasons such as oversupply due to markets, or individual consumer shopping/eating habits.

Did you know?

  • Around 7 million tonnes of food is thrown away by households in the UK every year, and most of it could have been eaten.
  • Little by little all this waste adds up, over a year the average family throws away around £700 of food shopping – equivalent to an annual utility bill.
  • Some of the waste is made up of things like peelings, cores and bones, but the majority is, or once was, perfectly good food.
  • Most of it ends up in landfill sites where it rots and releases methane, a damaging greenhouse gas. Throwing away food is also a huge waste of the energy, water and packaging used in its production, transportation and storage. If we all stopped wasting the food which could have been eaten, it would have the same CO2 impact as taking 1 in 4 cars off UK roads.
