You may remember that I made a few suggestions in my festive blog, ‘Can chemical engineers save Santa?’. One of my suggestions was to process the reindeer’s poo in order to produce biogas for fuel to help Santa travel around the globe to deliver presents.
But processing waste to biogas for fuel may not be limited to just our planet. Researchers at the University of Florida have been working towards the design of an anaerobic digester that can be used on the moon to power a rocket – this rocket would return astronauts back to earth.
NASA is planning to construct a lunar station over a period of five years between 2019 and 2024 with four crew members. So Pratap C. Pullammandappallil, associate professor of agricultural and biological engineering at the University of Florida and author of the study, has conducted research into optimising technologies for waste digestion.
