Coffee Log - Effortless Heating from the Circular Economy

At Paahtu, we give used coffee grounds a new life. We collect coffee grounds from local businesses and turn them into coffee logs — an entirely new type of firewood that burns hotter, longer, and more evenly than traditional wood.

Whether it’s a fireplace, a cottage sauna, or heating a hot tub, Coffee Log makes heating easier and more efficient. It lights quickly and burns for a long time, so you don’t have to keep adding logs to the fire. This allows you to enjoy steady warmth without unnecessary hassle.

Coffee Log also represents the best of circular economy practices — we don’t cut down trees but instead utilize coffee waste from businesses that would otherwise go to waste. Choose our innovation that combines coffee and heat in a unique way and takes heating to a more sustainable level.

No More Coffee Grounds in the Trash

Finns are famously passionate coffee drinkers. Coffee brings people together and sparks memories. However, the flip side of this passion is that around 66 million kilos of coffee grounds end up in the trash every year. We decided to save coffee grounds from the waste bin and give them a new purpose!

JOIN US IN PROTECTING FINLAND'S FORESTS

Finland is struggling to meet its 2030 sustainability goals, and one of the reasons for this is the decline in biodiversity, heavily impacted by deforestation. Through our efforts, we hope to promote a more sustainable future and preserve nature for future generations.

where it all began

The founder of Paahtu used to spend a lot of time in cafes with his wife, and during these visits, the idea of Kahviklapi was brewing in his mind. At the end of their cafe visits, they would ask employees where the coffee grounds went, and the answer was always the same – they ended up in biowaste. The couple took the used grounds with them and developed a prototype in their own kitchen.
