The baseline use of plant-based milk prior to instituting oat milk as the default was 16.6%. That jumped to 51.9% when baristas informed guests oat milk was the default option.
"Planning a sustainable wedding starts with prioritising what's important to you and shutting out the consumerist noise. That way, from the get-go you have a guiding principle that informs each decision."
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.
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.
Offsite construction has delivered measurable environmental gains, with a peer-reviewed study showing an average reduction of 78.8% in construction waste compared to conventional methods. Under controlled factory conditions, reductions can reach up to 90%, highlighting significant improvements in sustainability.
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.
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.
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.
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."
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 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.
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).
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.
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.
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.
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.
