Glass Sustainability: Recycling

In this video Faidra Oikonomopoulou & Telesilla Bristogianni explain that while glass is 100% recyclable in theory, in practice, successful closed-loop recycling is largely limited to the container industry (bottles and jars). For other glass products, like architectural and automotive glass, recycling rates are very low, with most post-consumer waste being downcycled or landfilled. The main barriers are technical, such as contamination from coatings and chemical incompatibility between different glass types, and logistical, including the difficult disassembly of complex products like windows. The video contrasts the high recycling rate of glass bottles in the EU (76%) with the minimal recycling of post-consumer float glass from buildings (under 1%). Solutions proposed include investing in new recycling methods like casting, establishing better collection facilities, implementing tracking systems for building materials, and designing products for disassembly from the start. The video concludes that overcoming these barriers is key to unlocking the full potential of glass recycling. The video was produced by the Open GLASSroom project.

Creating a circular healthcare economy: Circular strategies for a sustainable healthcare

Our world is the only planet, as far as we know, which harbors life. The number of humans on our planet has grown tremendously in recent centuries. In 1800 one billion humans occupied our earth; on 15 November 2022, this number reached 8 billion. A result of this growth, the emissions of carbon dioxide (CO2), the primary greenhouse gas emitted by human activities, drastically increased. The increased concentrations of greenhouse gases in our atmosphere foster the long-term increase of our earth’s temperatures, also referred to as global warming. While the earth’s population grew, so did our mass consumption society. After the Second World War humanity witnessed gigantic global economic development with great technological improvements. Computers, laptops, airplanes, tablets and Internet of Things connected humans all over the world. The hunger for plastics and steel grew as all products had to be manufactured in ever-increasing volumes. As the economy developed, our consumption grew apace. The healthcare sector has seen the same increase of consumption. The number of patients grew, and so did the number of single-use medical products. As products become more complex and more different materials were combined., recycling became more difficult. Thus, hospitals transformed into waste factories with ever-growing waste streams. The consumption of (disposable) medical devices takes up scarce raw materials and contributes to the growing CO2 emissions. In this book, Van Straten, Alvino and Horeman present their findings on how to create a sustainable healthcare economy by introducing different circular strategies. In 9 chapters, they present a wide variation of studies as practical cases to show what strategies and actions can be taken in order to implement sustainable strategies for a circular healthcare. This book was written in line with the courses the authors developed at TU Extension School, the open online education edX platform of Delft University of Technology/TU Delft, a leading university in science and technology, recognized for its world-class research. This book is a manual for everyone who follows the online course ‘Circular strategies for a sustainable healthcare’, but certainly also for everyone who wants to discover more about circular strategies and wants to understand the principles and practices of circular economy and urban mining. This book is suitable for students, researchers, policymakers and practitioners in the fields of healthcare sustainability, management, business and economics.

Toekomst zonder plastic? | Radboud Reflects Lecture by milieukundige Ad Ragas, chemicus Jeroen

Is een leven zonder plastic nog wel denkbaar? En in hoeverre is dit eigenlijk wel zo wenselijk? Zijn onze huidige recyclingmethoden effectief, of zijn er betere oplossingen nodig? Zijn alternatieven voor plastic een realistische oplossing? Duik dieper in deze vragen met milieukundige Ad Ragas en chemicus Jeroen Jansen. Laat je daarnaast meeslepen door muzikanten Rogier de Nijs en Sjaak van Dam die met hun performance Soundtrack of the Plastic Age een statement maken tegen de wegwerpcultuur en vóór een schonere wereld. Toekomst zonder plastic? | Lezingen, gesprek en muziek met milieukundige Ad Ragas, chemicus Jeroen Jansen en Soundtrack of the Plastic Age Maandag 7 oktober 2024 | 20.00 - 21.45 uur | LUX, Nijmegen Radboud Reflects en Faculteit der Natuurkunde, Wiskunde en Informatica

Introduction to Environmental Sustainability in Glass

In this video Rebecca Hartwell outlines the two key factors for sustainable glass design: material efficiency and energy efficiency. Material efficiency focuses on reducing the environmental impact from production to end-of-life, guided by the "9R framework". Energy efficiency concerns the glass's role in reducing a building's operational energy for heating, cooling, and lighting. The video explains that while advancements like double glazing and low-E coatings have improved energy efficiency, they often create complex, multi-material assemblies that are difficult to disassemble and recycle. Consequently, unlike container glass, most post-consumer flat glass is rarely recycled and is often downcycled or landfilled. A whole life-cycle perspective, balancing embodied and operational carbon, is essential for a sustainable glass future. The video was produced by the Open GLASSroom project.
