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.

"We didn't know what we had," Michele Stansfield, co-founder and CEO of Cauldron Ferm, told TechCrunch. But eventually, Stansfield realized they had more than initially thought.

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.

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.

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.

Industrial adhesives play a key role in modern assembly because they help manufacturers create secure connections while maintaining efficient production. When used correctly, they can improve product quality, support cleaner assembly, and contribute to more consistent manufacturing outcomes.

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.

Today's recipe began life as a way to use up garlic skins and herby leftovers, all of which contain a surprising amount of flavour, but it has evolved over time. Infused oil has countless uses drizzle it over carpaccio, pasta or salad, use it to marinate meat, fish and vegetables, or simply as a dip for chunks of sourdough and some of my favourites include lemon rind, garlic skin and rosemary;

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.

The team, from the Chinese Academy of Sciences and Beijing Institute of Technology, recently published their findings in Nature Communications. According to their research, the process not only avoids conventional leaching chemicals and extreme heat to extract lithium from old batteries, but it also uses carbon dioxide in what the authors call a sequestration step, and turns other battery transition metals into new catalysts - with CO₂-rich water doing most of the chemical work.

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.

"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."

the automation of heavy machinery enabled plants to operate continuously, increasing productivity and revenue. The downside was that any small hiccup was acutely felt, cascading through the production line. At first, it was assumed that inadequate lubrication of factory equipment was causing parts to seize up or break apart. And so, the Lubrication and Wear Group of the Institution of Mechanical Engineers, along with the Iron

Last week, I was making my morning coffee-you know, the complicated order I'm too embarrassed to say out loud at coffee shops-when I noticed the pile of used grounds in my filter. For years, I'd been tossing these straight into the trash without a second thought. But then I remembered something my grandmother wrote in one of her letters years ago: "The garden teaches us that nothing is truly waste."

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.

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.

AqueLyst approaches this challenge through odor elimination science, focusing on neutralizing odor-causing compounds at their origin. Rather than masking unwanted smells, the brand applies a science‑forward method that addresses odors at the molecular level. This approach reflects a shift away from traditional deodorizing practices and harsh chemical treatments, offering a responsible alternative for environments that require consistent, source-based odor control supported by practical chemistry and surface-safe formulations.

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.
