Spinning a sustainable future – The Underwood Medal (Day 313)

Mention the word ‘spinning’ to most people, and they might be transported back to their childhood and fairy tales of princesses in towers. They might think about industrial Britain in the 19th century, and the revolution in textile manufacture. Or they might be reminded of the gym session that they look forward to and dread in equal measure every week.

But for chemical engineers, spinning – of fibres into membranes for separation – can be a doorway to a sustainable future.

The winner of this year’s Underwood Medal for research in separations, Professor Neal Tai-Shung Chung, is a true master of the science and technology of hollow fibre membrane spinning.

Membranes offer several advantages in separation over alternatives such as distillation, sublimation or crystallisation. They permit the use both fractions (the permeate and the retentate) after separation and because no heating is involved, less energy is used.

Innovation for water for life (Day 152)

Arid groundThe World Health Organisation’s (WHO) prediction that over two thirds of the world’s population will face living with severe water shortages by 2050 is daunting.

The combination of population growth, climate change and dwindling resources make this a complex problem.

As someone who lives in the UK, this is something that has not really affected us. There have been summers when the water companies impose bans on using hose pipes to water gardens and wash cars. It makes the news headlines and interrupts daily lives, but a dirty car is nothing compared to the problems experienced elsewhere.

In other areas of the world, water scarcity is a daily reality – it’s not just areas of famine hit Africa, but the Middle East and Singapore too. We will all have to address this challenge, in our homes and in the industries that we work in.

Training the microbe (Day 111)

BacteriaLots of IChemE Members will be aware of the many special interest groups established to help advance the chemical engineering profession and its many branches.

One of the most active groups is IChemE’s Biochemical Engineering Special Interest Groups. Sharing best practice, supporting young professionals and generally promoting the discipline are all part of their work, which includes events on topics like synthetic biology and multi-disciplinary meetings for young researchers.
