#120 Recycled Plastic: The Canadian Potential Aug 12, 2021

Show notes

In 2019, Justin Trudeau declared war on plastic waste. And single-use plastics were listed as a toxic material in Canada in May of this year. Before long, Canadian companies will have to find a use for the immense quantity of material they generate. Yet the North American reprocessing industry is still young. Meanwhile, on the...

#119 The Grange: Saving Time, Saving Lives Aug 05, 2021

Show notes

As COVID-19 rampaged across the UK in 2020, society shut down and hospitals reached breaking point. For engineers building The Grange University Hospital in Cwmbran, South Wales their work took on a greater meaning. They had to make sure that this 450 bed critical care facility was completed ahead of time. Their actions didn’t just...

#118 Gateway: The Lunar Space Station Jul 29, 2021

Show notes

The last time a person walked on the moon was 14 December 1972. Almost 50 years ago. Since then, human operations have been confined to Earth orbit. But during that time, technology has not stood still. Now we are ready to take the next step. This episode we are talking to NASA about the Lunar...

#117 How Sails Could Save Shipping Jul 22, 2021

Show notes

The first boats that harnessed the wind to skip over the waves may have been built 8,000 years ago. Several hundred years later, the earliest seaborne trading networks began to form in the Aegean and the Persian Gulf. Modern cargo shipping relies on ‘bunker fuel’ a thick, black sludge made from the dregs of the...

#116 Climate Change: Islands on the Frontline Jul 15, 2021

Show notes

Island states are at the forefront of climate change. Rising sea levels mean more coastal erosion, overtopping of defences and salinification of land. More frequent and devastating severe weather events are disrupting everyday life and acidification of the ocean is impacting on fishing. It is happening now, not in decades to come. From atolls in...

#115 The Circular Road Jul 08, 2021

Show notes

In this episode we explain how one of the world’s biggest problems – plastic waste can be reused in state of the art, energy-efficient road-building products. Working with Cumbria County Council within an initiative called Adept Live Labs Shell will be publicly sharing the knowledge they are gaining in these lab trials, with the overall...

#114 Engineering with Dogs Jul 01, 2021

Show notes

Ecologists on infrastructure projects have some new team members: Conservation dogs. Their superior olfactory systems mean that they can sniff out a plethora of protected species from great crested newts and water voles, to bats and birds. Critically these canine detectives can do this more quickly, accurately and safely than humans. Thanks to pioneering work...

#113 Food Waste: Making a Net Zero Jet Fuel Jun 24, 2021

Show notes

Every year 1.3 billion tonnes of food are wasted. The waste occurs all through the supply chain, from the farm itself, all the way to the household. It represents enough calories to potentially feed every undernourished person on the planet, and there is an environmental cost to this. About 6% of all human greenhouse gas...

#112 Hagerbach: The Bat Cave of Tunnelling Jun 17, 2021

Show notes

Every good superhero universe has its origins story. Hagerbach’s begins with Rudolf Amberg, looking to innovate and find new efficiency savings for his iron mine. So began a 50-year journey from testing equipment and explosives, to fire and tunnel safety simulations, and ever more creative uses for underground space. Ultimately the mining industry in Switzerland...

#111 Machine Learning: Construction’s Future Jun 10, 2021

Show notes

When people think of digital tools to help with engineering problems, they usually think of a 3D model or a computerised image, representing something that exists in the real world. Machine learning is not that. What it does is completely alien to your way of thinking. It operates in such a way that is totally...
