Bio Reactor Operation Module


Our new Tool for precision fermentation

Precision Fermentation will revolutionize the production of food in the future (proteins, oil, fats, …). The use of “side streams”(not wastes) from food industry and of new, low cost precision fermentation equipment will lead into a new, highly feasible food processes. FLECKS B.R.O.M is an important part of this new development.

Bio Reactor Operation Module
is a highly feasible bioprocess solution and an
attractive TOOL in bioreactor technology. It has the
potential to increase the effciency on the route :
Labscale - semi industrial - industrial production
[Patent pending]

PALM+ Eurostars Project

PALM+ Eurostars Project


🎉🌍 🎉 Flecks Brauhaus Technik GmbH is proud to be a part of the PALM+ Eurostars Project, together with NoPalm Ingredients,Those Vegan Cowboys , Loki Foods, Háskóli Íslands , driving progress towards a greener future and making a positive impact on our planet. 🌿

The project will deliver eco-friendly oils & fats (NoPalm Ingredients) for use in dairy (Those Vegan Cowboys) and fish alternatives (Loki Foods) using brewery infrastructure (Flecks). The University of Iceland will support our efforts with crucial consumer/society acceptance studies. 🌱

Today we kick-off this exciting Palm+ Eurostars project. Stay tuned for updates on this groundbreaking project, and let's work together to build a more sustainable and eco-conscious food industry! 🤝🌎

Are you as excited as we are? Hit that 'Like' button and share the news! 💚
