Sunflower By-Product Elevates Bread Nutrition and Sustainability

Researchers found that partially defatted sunflower seed flour, a by-product of sunflower oil production, can replace 10%–60% of wheat flour in bread, significantly raising protein and fiber (up to 27.16% protein) and antioxidant levels, while also inhibiting α-amylase and pancreatic lipase; however, higher substitution can make loaves denser, though using an aqueous extract of the flour helped preserve texture, presenting a promising, cost-effective way to valorize a waste product and support a circular economy.

"Eggshell Waste: A New Source for Rare Earth Element Recovery in Green Energy"

Researchers from Trinity College Dublin and iCRAG have discovered that eggshell waste can be used to recover rare earth elements (REEs) from water, offering an eco-friendly and low-cost method for extracting these critical materials needed for green energy technologies. The study, published in ACS Omega, highlights how calcium carbonate in eggshells can absorb and separate REEs, potentially transforming waste into a valuable resource and supporting sustainable practices.

Revolutionary Recycling Method Eliminates Polyethylene Waste

Researchers at the University of Adelaide have developed a method to convert polyethylene waste into valuable chemicals using light-driven photocatalysis and solar energy, offering a sustainable solution to plastic pollution and contributing to a circular economy. The process upcycles polyethylene plastic waste into ethylene and propionic acid with high selectivity using atomically dispersed metal catalysts, harnessing renewable solar energy and addressing contemporary environmental and energy challenges. This innovative approach could revolutionize waste management and chemical manufacturing while reducing plastic pollution.

"Republic Services Unveils Revolutionary $75M Plastics Recycling Facility in Las Vegas"

Republic Services has opened a unique $75 million recycling plastics facility in Las Vegas, aiming to reduce plastic waste in landfills. The facility, called the Polymer Center, will convert water bottles into flakes and use them to create new plastic bottles, extending their lifecycle. It is expected to produce over 100 million pounds of recycled plastics annually and will be the first of its kind in North America. The plant is set to be operational by January 2024 and will have a significant economic impact on the northeast valley of Las Vegas. Coca-Cola will be the facility's first customer, committed to using 50% recycled plastics in its packaging by 2030.

"Fruit Peel Transformed: Italian Designers Craft Furniture Masterpieces"

Milan-based company Krill Design is creating furniture products made from a patented plastic-like biomaterial named Rekrill, which is fully organic, biodegradable, and can be reused and recycled. Using fruit peel, orange seeds, and coffee ground waste collected from businesses in Italy, Krill's designs include bookends, stools, clocks, bowls, and lamps. The company aims to reduce waste and carbon emissions by repurposing food waste that would otherwise be incinerated or dumped in landfills. While Rekrill is more expensive than common plastic, Krill hopes that as awareness of the environmental impact of unsustainable plastics grows, the material will become more widely used.

French Environment Minister's Anti-Shopping Campaign Sparks Intense Black Friday Debate

The French environment ministry's anti-shopping campaign, aimed at promoting sustainable consumption and transforming Black Friday into a Green Friday, has sparked controversy within President Emmanuel Macron's administration. While the campaign seeks to combat unsustainable over-consumption, it has faced criticism from cabinet members, including the economy minister, who is concerned about rising unemployment and reducing living costs. The campaign, initiated by the French Government's Agency for Ecological Transition, uses humorous TV ads to encourage individuals to question their buying decisions and promote a circular economy. However, the Confederation of Small and Medium-Sized Businesses has condemned the campaign, citing concerns over inflation and a slowdown in economic activity in the retail sector.

"Game-changing Bacteria Devour Ocean Plastic Pollution"

Researchers at Northwestern University have discovered a common bacterium called Comamonas testosteroni that has the ability to "eat" plastic, potentially revolutionizing plastic recycling efforts. With less than 5% of plastic currently being recycled, this bacterium could be used in large-scale recycling operations due to its natural ability to break down plastic without requiring modification. The researchers also found that the bacterium could recycle plastic into different polymers, reducing our dependence on petroleum chemicals. While not yet in use at recycling facilities, this breakthrough could pave the way for a more sustainable and circular economy.

"Breakthrough Method Purifies Glyphosate-Contaminated Water, Brazilian Researchers Reveal"

Researchers at São Paulo State University in Brazil have developed a method for removing glyphosate, a commonly used herbicide, from water using sugarcane bagasse. The technique involves isolating and chemically functionalizing the bagasse fibers, which can then adsorb glyphosate from water through processes like filtration or centrifugation. The researchers found that the most efficient removal occurred at pH 14. Glyphosate is known to pose health risks, and its use is restricted or banned in several countries. The method developed by the Brazilian researchers offers a potential solution for purifying water contaminated with glyphosate.

Reviving Old Mattresses: The Power of Chemistry in Polyurethane Recycling

Researchers at Aarhus University have developed a method to break down polyurethane foam mattresses into their monomeric building blocks, allowing for the extraction of polyol, a key component. By using this extracted polyol as a raw material, they have successfully replaced 64% of a mattress without compromising quality. The process, called solvolysis, offers a potential solution to the challenge of recycling polyurethane, which is difficult to recycle and often ends up in landfills. While the method is not applicable to all types of polyurethane, it represents a step towards a circular economy for flexible polyurethane foam.

Revolutionizing Rare Earth Element Discovery and Sustainability through AI

The demand for rare-earth elements (REEs) is rapidly increasing due to their crucial role in green technologies. However, their availability is limited, with China, the United States, and Russia controlling the majority of reserves and production. To meet soaring demand without damaging the environment, the REE industry needs to transition to a circular economy. This can be achieved by boosting global REE recycling, implementing compulsory take-back policies, investing in tracking and recovery technologies, reworking supply chains, and fostering global collaboration. These measures would ensure a sustainable and fair distribution of REEs, support green industries, and accelerate the global energy transition.
