Fonterra Challenge: Optimal Biogas Utilisation

Posted June 26, 2019

Biogas is a renewable fuel produced during the decomposition of organic waste. Fonterra recently opened a state-of-the-art cream cheese plant located in Darfield, New Zealand. With the addition of a biodigester, the plant will generate a large quantity of biogas. Therefore, Fonterra is searching for innovative approaches to harness biogas and create a cost-effective energy source.

This Theoretical Challenge requires only a written proposal.


Although biogas composition varies based upon the raw material, the two primary components are methane and carbon dioxide. Nitrogen, hydrogen, hydrogen sulphide, and oxygen are also found but in lesser quantities. Due to the presence of greenhouse gases, it is undesirable to release biogas directly into the environment. Furthermore, the conversion of biogas into heat, electricity, and fuel helps decrease our planet’s reliance on fossil fuels. To advance its commitment to produce dairy nutrition in a sustainable manner, Fonterra is interested in finding the best ways to utilise biogas effectively.

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on July 18, 2019.
