Welcome to Melt&Marble

From day one, all of us at Melt&Marble (formerly Biopetrolia) have been looking to provide solutions to some of today’s sustainability challenges. That’s why we exist.


It all began in Jens Nielsen’s Systems and Synthetic Biology group at Chalmers University of Technology in Gothenburg, Sweden. The group, known for its in-depth knowledge and world-leading expertise in synthetic biology and metabolic engineering of microbial cell factories, decided to make a change.


Initially, the company was a patent-holding company for the research group, financed by providing yeast engineering services.


In 2021 we pivoted to focus on creating the best possible fats for the food industry and beyond. The world needs to change…

Our vision

Fats play an essential role in many consumer products. Meat and dairy fats give these products their characteristic mouthfeel, juiciness, and flavour. Cocoa butter gives chocolate its smooth, luxurious mouthfeel. In personal care applications fats are widely used for their moisturizing and thickening properties.

However, the vast majority of fats produced today are unsustainable, lack needed functionality, and/or are plagued by supply chain instabilities.

Melt&Marble’s mission is to be part of the solution.

With our technology, we can supply different industries with the most delicious, sustainable, and healthiest fats- better for consumers and the planet.
