The metals include uranium, arsenic, cadmium, chromium and mercury. This acid mine drainage – when water mixes with heavy metals in mines
In 2014, Professor Kai Zacharowski, Director of the Clinic for Anaesthesiology, Intensive Care Medicine and Pain Therapy at the Goethe University Hospital of Frankfurt, Germany, was treating a particularly complicated case of an Ebola patient in acute respiratory distress. As the man’s condition worsened, Zacharowski reached for a new experimental drug – a molecule
As the world grapples with the mounting consequences of climate change, the engineering sector stands at the forefront of the battle to create a sustainable future. The challenge is formidable, requiring innovative solutions to reduce greenhouse gas emissions, improve energy efficiency, and develop sustainable infrastructure. This article explores the latest trends in green
In the contemporary era, the concept of sustainability has emerged as a foundational pillar in design and engineering, driving innovations aimed at minimising environmental impact and promoting eco-friendly practices. Eco-friendly materials, or green materials, represent one of the cornerstones of this transformation. They are essential for reducing the carbon footprint of buildings, improving
In recent years, the discourse around sustainability and environmental conservation has intensified, thrusting green engineering into the spotlight as a pivotal force in addressing the myriad challenges posed by climate change and resource depletion. Green engineering, which integrates principles of sustainable development into engineering practices, is reshaping industries and societies in profound ways,
In an era where environmental concerns have ascended to the forefront of global discourse, green entrepreneurship has emerged as a crucial force for driving sustainability. The convergence of innovation and environmental stewardship is not merely a trend but a necessary evolution in the face of climate change, resource depletion, and ecological degradation. This
The 34 dairy cows chewing the cud on a floating platform in the port of Rotterdam probably aren’t thinking about water scarcity – a major challenge in the world today – but they are participating in a Europe-wide effort to find solutions to this modern-day dilemma. The cows’ home, the Floating Farm, is part
Building sustainably has become an imperative in modern architecture, driven by the urgent need to address climate change, reduce carbon footprints, and create resilient, energy-efficient structures. The concept of green engineering in modern architecture encompasses a wide range of practices and principles aimed at creating buildings that are not only environmentally friendly but
ph. Don’t flush any wet wipes – even if they are ‘plastic free’ or ‘biodegradable’. Maridav / shutterstock Randa Lindsey Kachef, King’s College London The UK government recently announced a plan to ban plastics from wet wipes, causing my fellow river activists to release a collective sigh of relief. However, although a general
The transportation sector has long been a significant contributor to environmental degradation, with emissions from vehicles accounting for a large percentage of the world’s greenhouse gases. As the planet grapples with the escalating climate crisis, the need for sustainable mobility solutions has never been more pressing. In recent years, there has been a
