Meininger, who grew up in Germany but now lives in London, likes making things. So when he saw how much his young sons enjoyed the jungle gym and play forts at the local park, he made an indoor treehouse for them.
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.
By January 2026, over a quarter of Americans will live in states with right-to-repair laws, and that number should rise to more than 35% by fall 2026 when Connecticut and Texas join in. The European Union also passed a Right to Repair Directive in 2024, which will apply to all EU countries by July 2026. These rules make manufacturers give consumers and independent repair shops the tools, parts, manuals, and software needed to fix their own products.
According to the UN's Global E-waste Monitor 2024, a record 62 million metric tons of electronic waste was generated worldwide in 2022, an 82% increase since 2010. E-waste is projected to reach 82 million metric tons by 2030. In the U.S. alone, roughly 8 million tons of e-waste is discarded each year.
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.
Americans are likely to have spent a record $1 trillion-plus this holiday shopping season alone, and about $5.5 trillion in retail sales in all of 2025, according to estimates by the National Retail Federation. That includes many unhappy returns for retailers: And when it comes back to them, a lot of the $850 billion in returned merchandise is often cheaper to discard than to inspect, sort, and resell-adding millions of tons to landfills every year.
The advertising industry has always been in the business of making things, such as the OOH billboard, the 30-second spot, the snappy social post, the standard website: final, finite assets polished and pushed into the world. Agencies were paid, often by the hour, for producing final versions of these things and then moved on to the next project. Even with generative AI entering the picture, much of the conversation remains focused on making those same things faster or cheaper.
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.
When you think about building a house, what materials come to mind? Brick, wood and metal all come to mind; there are also some very distinctive glass houses out there. (Even if their occupants should refrain from throwing stones - though honestly, that's a good tip for indoor living in general.) A group of MIT researchers have come up with a very different way of making buildings, and it's one that also addresses an ongoing waste issue."We've estimated that the world needs about 1 billion new homes by 2050. If we try to make that many homes using wood, we would need to clear-cut the equivalent of the Amazon rainforest three times over," explained AJ Perez, who conducts his research in the MIT Office of Innovation. The title of a paper written by Perez and his colleagues - "Design, Manufacture and Testing of Structural Trusses Using Additively Manufactured Polymer Composites" - gives a sense of the solution that they have in mind.
We can make changes to reduce our waste by precycling when we shop, reducing what we purchase, reusing items to get the most use out of them, and recycling when possible. But when we have items to throw away, please dispose of trash responsibly and don't litter. Let's reduce our waste and clean up our planet. It's our only home.
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.
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.
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).
