This week on Infrastructure Connections we're talking to Veena Sahajwalla about micro recycling and the circular economy. The takeaways from this episode give us new ways to look at circularity: 1. Companies are starting to re-think their identity. "We're not a waste company, we're a supply company." We supply resources as feedstock, resources that used to be waste for someone else. 2. "If we zoom down to the micro recycling level, every material is important." If it was an important component of the original product, it will be important to recover for the next product. 3. "Sustainability is a normal way to think. The more we can make it a norm, the more we can think of practical ways in which sustainability comes to life." 4. We need to think of sustainability and recycling on a local level, specific to the local industries who need it, and make that recovery a priority. This is compared to the current method of sending our waste overseas and then buying it back as sources. Veena puts the re in resource. Veena is the Director of SMaRT Centre (Sustainable Materials Research & Technology) and Associate Dean (Strategic Industry Relations) faculty of Science, University of New South Wales. Her research interests include sustainability of materials and processes with emphasis on environmental benefits. She invented an environmentally friendly process for recycling plastics and rubber tyres in electric arc furnace steelmaking. She is an international award winning engineer. In 2012 she was named Overall Winner of the Australian Innovation Challenge Award. She was awarded the 2012 Banksia Award, the GE Eco Innovation Award and the 2005 Eureka Prize for Scientific Research. We hope you enjoy this episode.

S2E1 - Material Circularity Indicators w/ Steve Porter
Welcome back to Infrastructure Connections, the podcast where we explore what makes sustainable infrastructure work, brought to you by the Infrastructure Sustainability Council. I'm your host, Seth Scott. And hooray! We made it into Season 2. This season we're exploring Circularity and the role it plays in infrastructure. What better way to start off than by looking at the circularity metrics of steel, a product that is virtually 100% recyclable. Nearly half of all steel is used in the infrastructure and construction industry, things like bridge beams and reinforcing bars and mesh, and much of the rest is used on what uses infrastructure, the planes, trains and automobiles. So today we'll be talking about steel with Steve Porter of Infrabuild. Steve is Head of Sustainability, Innovation & Trade at InfraBuild Australia, Australia's largest integrated manufacturer and supplier of steel long products. He's spent most of his career as a General Manager in the steel industry, and he is committed to shaping a sustainable, low-carbon future in energy intensive environments. We discuss circularity initiatives in the steel industry, initiatives like the Electric Arc Furnace which allows phenomenal recycling of scrap metal using renewable energy. We also look at how Material Circularity Indicators (MCI) can enhance EPDs for customers. For even more information, InfraBuild collaborated on the ISC Impact Notes on the Circular Economy, which you can find here: https://www.iscouncil.org/wp-content/uploads/2024/02/Circular-Economy-Impact-Note_Final-for-Publication.pdf

Episode 5 - Taskforce for Nature Based Financial Disclosure w/ Sam Donaldson
Guest Speaker Sam Donaldson, Hub Sustainability Leader at Laing O’Rourke discusses the practice of Nature Based Financial Disclosures as a practitioner who has seen this work in the field. We also zero in on the implications it has for the future of sustainable infrastructure.

How AI and physics create high-resolution climate projections
Host Seth Scott discusses with Guest Speakers Neelesh Rampal, Climate Data Scientist and Dr Peter Gibson, Climate Scientist both from NIWA on the role of data in New Zealand climate projections. We looked into their NIWA research on "High-resolution climate projects using physics and AI" and tackled its potential impacts on infrastructure.
