steelTalks is a series on topics of interest to the global steel community. The lectures are presented in a webinar format with a guest lecturer. In this webinar, Tim Collins, Secretary General of worldstainless, will explain how and why tea staining occurs and outline practical steps that material specifiers, fabricators and end users can take to prevent it and maintain the desired appearance of stainless steel in service.

steelTalks is a series on topics of interest to the global steel community. The lectures are presented in a webinar format with a guest lecturer. In this webinar, we will examine the selective use of stainless steels in structures and explain how this approach can support more resilient, lower-maintenance and lower-emissions infrastructure. The session will explore why life-cycle thinking is important for materials selection decisions, particularly in environments exposed to chlorides, sulphur dioxides and other corrosive media. Tim Collins, Secretary General at worldstainless, will outline the concept of selective stainless steel use in structures and illustrate, through real-world examples, why this approach should be more widely considered in structural design.

Created by The Willy Korf Foundation and Kallanish Commodities, The Green Steel Challenge sparks conversation, drives innovation, and accelerates change toward decarbonising the steel industry.

Stirring the Pot is a podcast by HERA that explores innovation, sustainability, and transformation in New Zealand’s metals industry. Through conversations with experts, it delves into topics such as low-carbon steel, digital construction, workforce development, and cultural integration, aiming to challenge traditional thinking and inspire progress across the sector.

This course, Introduction to Life Cycle Assessment, introduces the methodology to analyse the environmental burdens of product and service systems.

This course introduces the Low-Carbon Circular Design Framework — a material- and typology-agnostic approach to guiding sustainable construction design. Participants will learn how to apply strategies that minimize embodied carbon, enhance circularity, and integrate life cycle thinking across all design phases.

Today, the construction industry is at the heart of the global sustainability challenge. Buildings and infrastructure account for nearly 40% of the world's energy-related carbon emissions.

The reason for shifting from linear to circular economy and the benefits doing will be introduced in the first part. Then, the role of steel in the circular economy. Finally, the advantages of circular economy will be described.

This course will touch upon topics like energy efficiency, resource efficiency and carbon footprint of EAF steelmaking. The concepts will be defined and factors influencing the sustainability will be discussed. Finally, options to increase the sustainability of EAF steelmaking like fossil carbon substitutes, energy efficiency improvements and circular economy approaches will be presented.

Do you know the difference between global warming and climate change? How about the causes or the impacts of it today and in the future? Some of these terms and concepts are talked about so often in today's world but we don't stop to check we understand what they mean!

ESG, an acronym based on the terms Environmental, Social, and Governance, was coined in 2004 in a publication by the UN Global Compact in partnership with the World Bank titled Who Cares Wins. This report introduced the pillars of corporate structure that, according to the study, are most likely to succeed when ESG practices are implemented. Today, ESG is regarded as a new form of corporate sustainability, addressing issues that are fundamental to sustainable development.

This course explores the non-ferrous metals manufacturing industry, with a focus on aluminium, copper, zinc, and nickel. It covers the complete production process from ore extraction to final product refinement, highlighting best practices for energy efficiency and sustainability.
