In the quest for sustainable and environmentally friendly methods of resource recovery, researchers have developed a novel approach to extract gold from electronic waste (e-waste) using whey protein, a byproduct of the cheesemaking process. The Challenge of E-Waste E-waste is a growing environmental concern, containing valuable metals like gold (Au), which are often difficult and…
In the quest for sustainable waste management solutions, a novel approach has emerged utilizing spent brewer’s yeast, a byproduct of the beer brewing process, to filter out metals from waste streams. This method offers an eco-friendly and cost-effective alternative to traditional metal recovery processes. Electronic waste (e-waste) is a growing environmental concern due to the…
The automotive industry is increasingly focusing on sustainability, with a significant emphasis on reducing the carbon footprint of its manufacturing processes. Among these, automotive paint shops are notable contributors to greenhouse gas (GHG) emissions, primarily due to high energy consumption and volatile organic compound (VOC) emissions. Understanding the Impact A typical automotive paint shop is…
Lead is a toxic heavy metal that can cause serious health problems, especially for children and pregnant women. Exposure to lead can affect the brain, nervous system, kidneys, blood, and bones. According to the World Health Organization (WHO), there is no safe level of lead in drinking water. Therefore, it is important to monitor and control…
In many parts of the world, access to clean drinking water is a significant challenge. The introduction of portable water filters has been a game-changer, especially for those in remote or underdeveloped areas. Among the latest advancements in this field is the hydrogel-based filtration system, which stands out for its efficiency, cost-effectiveness, and sustainability. Understanding…
Grit is a term used to describe the sand, gravel, and other abrasive particles that enter wastewater treatment plants. Grit can cause serious problems for the plant’s equipment and processes, such as clogging pipes, wearing down pumps, and reducing the efficiency of biological treatment. Therefore, it is essential to remove grit from the wastewater stream…
Carbon neutrality, or net-zero emissions, is the goal of reducing greenhouse gas (GHG) emissions to zero or offsetting them by removing an equivalent amount from the atmosphere. This is a crucial step to mitigate the effects of climate change and ensure a sustainable future for our planet. However, achieving carbon neutrality is not an easy…
Nuclear weapons are one of the most powerful and destructive inventions of humanity. They have the potential to cause massive devastation and harm to people and the environment. Therefore, it is important to monitor and prevent the proliferation and testing of nuclear weapons by rogue states or terrorist groups. However, detecting nuclear tests is not…
Trucks are one of the major contributors to greenhouse gas emissions in the transport sector, accounting for about 6% of global CO2 emissions. To tackle this challenge, researchers have developed a novel system that can capture CO2 from truck exhaust and store it in liquid form on the vehicle. The system can reduce truck CO2…
Lubrizol, a specialty chemical company that produces engineered polymers for various industries, has announced that three more of its sites have achieved the International Sustainability and Carbon Certification (ISCC) PLUS certification. This certification is a globally recognized standard for sustainable supply chains, which allows companies to track and attribute environmentally friendly raw materials along the…
