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.

Environmental monitoring has traditionally relied on snapshots of exposure from a water sample collected on a single day, a blood sample drawn at one point in time, or soil tested from a specific location. But exposure unfolds gradually as people move through different environments and come into contact with air, dust, and surfaces throughout the day.

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.

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.

Printed signs get reprinted every week, while full LCD signage burns power all day just to show a static promo. E-ink has quietly solved this in e-readers by holding text without sipping battery, but it has not shown up in everyday public spaces where signs still get taped to shelves. Samsung's new 13-inch Color E-Paper is a panel that tries to live in that middle ground, digital enough to update remotely, quiet enough to blend in.

"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."

They write, 'through clever processing changes, this material is now stronger, more beautiful, and available in higher volumes at a lower price point.' The design remains the same with the frosted look, and this time, it can carry loads better but still lasts only as long as it's needed. After use, the bags can be placed in home compost or industrial compost systems, where they break down into healthy soil.

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).

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.

Clean Harbors just locked in a $110 million contract for PFAS water filtration at Joint Base Pearl Harbor-Hickam. This isn't just another project win. It's validation of the company's end-to-end PFAS solution: lab analytics, water filtration, site remediation, and most critically, high-temperature incineration disposal.

Button cell batteries are the small, flat, round batteries found in watches, hearing aids, car key fobs, calculators, and medical devices. Although they are tiny, these batteries contain valuable materials that can be recovered and can harm the environment if not handled or disposed of correctly. The main challenge in recycling button cells is their small size and the difficulty of sorting them.
