About Us

Coffee Reloved

Preloved Coffee is a Turku-based start-up with a passion for sustainability and innovation. Our mission is to upcycle spent coffee grounds and turn them into high-quality bio-materials for businesses. By doing so, we help our local partners, coffee shops, offices and shopping centres reduce their carbon footprint and contribute towards achieving Sustainable Development Goals.

At Preloved Coffee, we firmly believe in the power of the circular economy. By transforming “waste” into value, we create a more sustainable and resilient future for our planet. Our commitment to mitigating climate change and promoting sustainability is at the heart of everything we do. Our first bio-product, coffee oil, is just the beginning of our journey. With its versatile applications in cosmetics, flavouring and pharmaceuticals, we are excited to pave the way for more sustainable and eco-friendly solutions in various industries with our bio-materials.

We are inviting coffee shop owners, companies, roasteries and shopping centres located in the Turku area to join us on this journey towards a better, more sustainable future.

Let's make a positive impact together, one coffee ground at a time!
