Small organic molecules underpin modern life, from medicines and flavours to advanced materials. Much of this functional diversity comes from shape: modest changes in a molecule's 3D structure can completely change its properties.
The #6 symbol on the foam container only tells you what kind of plastic it is, not if it can be recycled. If you put it in the bin just because you see a number and the recycling arrows, it can actually contaminate your other recyclables, like paper, cardboard, and aluminum, and might cause the whole batch to be rejected.
In the nineteenth century, entire railway networks became obsolete almost overnight, not due to physical deterioration, but because of changes in the technical standards that supported them. The expansion of railroads across Europe and North America adopted different track gauges, and as a dominant standard gradually emerged, these infrastructures became incompatible with one another.
Most water filter pitchers are made of BPA-free plastic. But as new research shows that bottled-water drinkers ingest tens of thousands of excess microplastic particles, wellness lovers have begun to look askance at water filters that are themselves made of plastic.
Shredded paper is especially difficult to recycle, so many programs will not accept it. Shredding accelerates fiber shortening and lowers the paper grade from high-grade to mixed-grade. Mixed-grade paper is still recyclable, but it ends up baled and processed into products like paper towels and packing paper.
Industrial adhesives play a key role in modern assembly because they help manufacturers create secure connections while maintaining efficient production. When used correctly, they can improve product quality, support cleaner assembly, and contribute to more consistent manufacturing outcomes.
The body of the robotic fingers is built from polyglycerol sebacate, a synthetic elastomer made from glycerol and sebacic acid. Glycerol is a byproduct of biodiesel production while sebacic acid is derived from castor oil, and both of them are plant-based. Polyglycerol sebacate is safe since it is already used in medical implants because the body can absorb it without a toxic response.
Crude oil is a complex mixture of hydrocarbons - molecules made mainly of carbon and hydrogen. Refineries and chemical plants separate and transform these molecules into smaller chemical building blocks known as petrochemicals. Some of the most important petrochemical building blocks include chemicals such as ethylene, propylene and benzene.
Your eyes don't deceive you. The use of polyester has ballooned with time, according to Henry Navarro Delgado, an associate professor at Toronto Metropolitan University's school of fashion. It's partly because polyester can be quite useful, he said. It is a type of plastic made from petroleum compounds that are cooled and stretched into yarn, according to Michael Palladino, a fashion industry veteran and lecturer at Kingsborough Community College's business of fashion program in New York.
This corn-based construction material was made by Manufactura, a Mexican sustainable materials company, and it imagines a second life for waste from the most widely produced grain in the world. The project started as an invitation by chef Jorge Armando, the founder of catering brand Taco Kween Berlin, to find ways he could reintegrate waste generated by his taqueria into architecture. A team led by designer Dinorah Schulte created corncretl during a residency last year in Massa Lombarda, Italy.
In Indra's Net of pearls and jewels, every gem reflects every other, a shimmering image of interdependence. This ancient Vedic metaphor for connection across the cosmos also illuminates what the environmental philosopher Glenn Albrecht first proposed in 2014as 'theSymbiocene': the era after the Anthropocene, in which human technologies take their cues from living systems and work in partnership rather than through dominance.
Now, researchers have created an artificial-intelligence system that vastly simplifies and accelerates the process of chemical synthesis. The system, which is called MOSAIC and is described in a study published in Nature on 19 January, recommended conditions that researchers were able to use to generate 35 compounds with the potential to become products like pharmaceuticals, agrochemicals or cosmetics without needing to do any further trawling or tweaking.
More research is needed, however, for government agencies to determine whether the chemical levels found in these products requires greater regulation, the study authors say. The hazardous chemicals we identified each carry their own risks, says Elissia T. Franklin, lead author of the new paper and a research scientist at the nonprofit research organization Silent Spring Institute. Our findings showed that these products can expose [people] to multiple chemicals over time, and through repeated use, these combined exposures add up.
the automation of heavy machinery enabled plants to operate continuously, increasing productivity and revenue. The downside was that any small hiccup was acutely felt, cascading through the production line. At first, it was assumed that inadequate lubrication of factory equipment was causing parts to seize up or break apart. And so, the Lubrication and Wear Group of the Institution of Mechanical Engineers, along with the Iron
Black plastic gets its color from carbon black pigment and is commonly used in food containers, such as meat or produce trays and take-out containers, as well as disposable coffee lids, plastic bags, and hard plastic items like DVD cases and planters. While plastic is one of the categories of things that we are encouraged to recycle - when we can't reuse or repurpose it - not all black plastic items can be recycled.
This research-based design project by Laura Oliveira investigates discarded as a potential raw material for sustainable design applications. Human hair is produced continuously and in large quantities through everyday grooming practices, yet it is almost always treated as waste once separated from the body and typically disposed of in landfills. Despite its material properties, strength, flexibility, and durability as a keratin-based protein fiber, its remains uncommon within design and research contexts.
In a balance of aesthetics, performance, and versatility, HIMACS shows a solid surface material of choice for many architects and designers. Taking a further step forward, the entire range of standard HIMACS sinks and basins is now officially SCS certified, containing a minimum of 8% pre-consumer recycled content. This certification enhances the material's technical and visual appeal by providing a more sustainable option without compromising quality or functionality.
Each piece begins with used coffee pods collected from my community, materials that were never meant to last beyond a single use. Before any design work begins, the pods must be cleaned, sanitized, flattened, cut, folded, and shaped entirely by hand. They arrive dented, stained, and inconsistent, carrying the marks of their previous life. Learning how to work with those imperfections, rather than erasing them, was one of my first challenges.
The vascular system and the brain are examples of physical networks that differ from the networks typically studied in network science owing to the tangible nature of their nodes and links, which are made of material resources and constrain their layout. The importance of these material factors has been noted in many disciplines: as early as 1899, Ramón y Cajal suggested that we must consider the laws conserving the 'wire' volume to explain neuronal design8
Signs of ageing accelerated when fish were exposed to the chemicals, according to the study, which could have implications for other organisms. Chemical safety regulations tend to focus on short-term exposure to high doses of pesticides and other chemicals, but the study focused on long-term exposure. Low doses of pesticides are widespread in the environment, so their effects should be studied and understood, the authors said.
Europe's supermarket shelves are packed with brands billing their plastic packaging as sustainable, but often only a fraction of the materials are truly recovered from waste, with the rest made from petroleum. Brands using plastic packaging from Kraft's Heinz Beanz to Mondelez's Philadelphia use materials made by the plastic manufacturing arm of the oil company Saudi Aramco. The Saudi state-owned holding opposes production cuts under the UN plastic treaty and is the world's largest corporate greenhouse-gas emitter (over 70m tonnes up to 2023).
One of the earliest large-scale examples of composite materials can be found in the Great Wall of China, where stone, clay bricks, and organic fibers such as reeds and willow branches were blended to create a resilient and lasting structure. These early techniques reveal a timeless intuition: distinct materials, when combined thoughtfully, produce properties unattainable by any single element.
According to research by the World Economic Forum and United Nations Development Programme, the circular economy could unlock $4.5 trillion in new global value by 2030, and investors are racing to capture part of that opportunity. Meet Elizabeth Blankenship-Singh, Director of Innovation at Overlay Capital, an Atlanta-based alternative investment firm whose Waste and Materials Fund is backing both early-stage materials innovators and later-stage recycling operations with established infrastructure.
Just like that coffee cup, eyewear is a complex fusion of materials. Metal hinges are screwed into polymer frames, which hold chemically-coated lenses. This mix of metals, plastics, and coatings means standard sorting machines cannot process them. As a result, they are rejected as contamination and sent directly to landfills, where they contribute to non-biodegradable waste. Unlike a disposable paper cup, however, a pair of sunglasses is built for durability. Its high-quality components make it a perfect candidate for repair, reuse, or reinvention.
Mexico's construction sector faces significant environmental and social challenges. The widespread use of carbon-intensive materials has positioned the industry as a major contributor to national CO₂ emissions. At the same time, construction labor conditions remain unstable, with limited access to technical training and high occupational risk. CORNCRETL, developed by MANUFACTURA, proposes a circular material strategy that addresses both environmental impact and production models within the building industry.
New filtration technology developed by Rice University may absorb some Pfas forever chemicals at 100 times the rate than previously possible, which could dramatically improve pollution control and speed remediations. Researchers also say they have also found a way to destroy Pfas, though both technologies face a steep challenge in being deployed on an industrial scale. A new peer-reviewed paper details a layered double hydroxide (LDH) material made from copper and
