Overview

As fossil-based fuels and raw materials contribute to climate change, the use of renewable materials and energy as an alternative is increasingly important and common. This transition is not a luxury, but rather a necessity. We can use the unique properties of microorganisms to convert organic waste streams into biomaterials, chemicals and biofuels. This course provides the insights and tools for the design of biotechnology processes in a sustainable way. Six experienced course leaders will teach you the basics of industrial biotechnology and how to apply these to the design of fermentation processes for the production of fuels, chemicals and foodstuffs.

Throughout this course, you will be encouraged to design your own biotechnological process and evaluate its performance and sustainability. This undergraduate course includes guest lectures from industry as well as from the University of Campinas in Brazil, with over 40 years of experience in bio-ethanol production. The course is a joint initiative of TU Delft, the international BE-Basic consortium and University of Campinas.
