Burning gas and propane for cooking, water heating and space heating in California homes and businesses creates 10% of the state's greenhouse gas emissions. It also releases pollutants indoors.
tozero's proprietary acid-free hydrometallurgical process runs in a single cycle and produces materials pure enough to feed directly back into battery cell manufacturing without further refinement.
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.
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.
By bricking your plastic, the company claims it'll no longer jam recycling equipment the way individual plastic bags often do. Just feed your plastics into this 61-pound bin and watch them magically disappear into its whirring slot. Wait for it to spit out a brick weeks later, drop it into a supplied bag, and let the US Postal Service whisk your guilt away.
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.
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.
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.
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.
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).
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.
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.
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.
