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.
Even long after the tell-tale odor of new paint has vanished, traditional paint can off-gas for months, releasing volatile organic compounds (VOCs) that have been linked to organ and nervous system damage, cancer, and infertility.
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.
While you might assume that potato chip bags or other snack bags are recyclable, most are made from mixed materials. This means that the bags may contain plastic on the outside and an inner lining of plastic and aluminum film or foil. While the individual materials may be recyclable on their own, the only way they could be used is if the recycling facility has the means by which to separate the materials.
Photovoltaic (PV) solar energy represents a modular technology that can be manufactured in large-scale facilities, generating economies of scale, while also being adaptable to small-scale applications. From residential rooftop systems to large-scale power generation installations, photovoltaic solar energy has established itself as a cost-effective option for electricity production in many countries around the world.
Never place batteries of any type in your curbside recycling bin. Batteries can damage recycling equipment and, if lithium batteries are mixed in, cause fires. Always use designated battery collection programs.
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.
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.
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.
If you spend a lot of time in the kitchen, you may find yourself needing to use a lot of disposable plastic products, from plastic bags to plastic wrap. While these tools can come in handy once in a while, a lot of sustainability- and health-conscious home cooks try to avoid them as much as possible. There are concerns that chemicals leached from plastic wrap could cause health issues, and being disposable and decidedly not biodegradable, many view these types of food storage tools as bad for the environment as well (and a great way to cut down on plastic waste in the kitchen).
Researchers at the Norwegian University of Science and Technology and the University of Tokyo have made a prototype of botanical cement made of desert sand and plant-based additives in hopes that it can be used to build houses and roads. Once mixed, the team adds tiny pieces of wood together and presses them all with heat to produce the cement.
"Ironically, many if not most of these 'sustainability' projects remain disassociated from companies' core procurement strategies, meaning the coffee produced from these projects is not necessarily bought by the companies involved, or only in minimal quantities," the paper states. "And for the coffee that is purchased, prices do not factor into the project design, despite the fact that price is the single variable impacting farmer income that is in the direct control of companies."
This is the one and only paint that's on the market that's designed to actually absorb moisture. If you take Lilypad paint and apply it to the wall, the film will actually absorb excess humidity as it starts filling the room, and then, when it dries, it resets itself by slowly letting it back into the space. So it's regulating humidity, Dr. Stein said.
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.
It looks like ordinary paint, but a new coating called Lilypad Paint has a hidden ability to pull moisture out of the air. It works like a dehumidifier, without the energy use. If it's on the wall in your bathroom, it can suck water vapor out of the air after you've taken a shower. The paint holds the humidity in nano-size pores, and then slowly releases it as humidity levels fall in the room.
From the large industrial roofs and galleries of the 19th century to the contemporary atriums of museums and public buildings, glass has been a recurring material in shaping large and monumental interior spaces. More than a technological or engineering solution, these horizontal glazed planes introduce a distinct luminous quality: light that comes from above. Unlike lateral daylight entering through façades, zenithal light is more evenly distributed, reduces harsh shadows, and lends spaces a sense of continuity and openness that is difficult to achieve otherwise.
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.
It's likely that you've encountered recycled glass countertops without realizing it. They're far from the hippie-style broken-glass mosaic art of yesteryear, instead presenting as sleek, highly polished, professional slabs with intriguing bits of confetti-style color trapped inside. That's the recovered glass bits set into a binding material such as resin, cement, or concrete, and then smoothly polished so that the composite surface feels like stone.
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.
Then she read an article in this newspaper, just over eight years ago, and discovered that fossil fuel companies had ploughed more than $180bn (130bn) into plastic plants in the US since 2010. It was a kick in the teeth, says Gardiner. You're telling me that while I am beating myself up because I forgot to bring my water bottle, all these huge oil companies are pouring billions She looks appalled. It was just such a shock.
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.
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.
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).
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.
According to the UN, the "buildings and construction sector is by far the largest emitter of greenhouse gases." Sustainable architecture, in essence, tries to change that-and is more needed than ever. As climate change intensifies, it challenges architects and designers to consider the impact of their work in every step of the building process, from raw materials to site impact to future maintenance, decades down the line.
Lithium-ion (Li-ion) batteries are found in many devices we use every day, like smartphones, laptops, tablets, wireless earbuds, power tools, e-bikes, and electric vehicles. By 2023, there were more than 40 million electric vehicles on the road worldwide, and billions of portable electronics used Li-ion cells. These batteries are valuable for recycling, but they can be dangerous if not disposed of correctly.
Toilet paper, a product that is used for a few seconds before being disposed of forever, is typically made with trees, energy-intensive manufacturing processes and chemicals that can pollute the environment. Experts say more consumers are seeking toilet paper made from recycled content or sustainable materials, but it can be hard to know what to look for. Sustainable toilet paper often costs more, but can have significant environmental benefits.
