The heat from city trash dumps is a big deal. In Tamil Nadu, India, cities like Chennai, Coimbatore, and Erode are feeling the burn. These places have huge piles of trash that are not managed well. This trash is not just an eyesore; it's also a fire hazard. The heat from the trash can get so high that it can start fires on its own. This is a big problem because it ca...
Denim is everywhere. It's tough, it's blue, and it's a staple in closets worldwide. But what happens when our favorite jeans wear out? Most end up in landfills or are burned, which is a huge waste. Over 80% of discarded denim meets this fate. That's a lot of wasted material. Imagine if we could give old denim a new life. A recent strategy shows promise. Firs...
Water treatment is a big deal. It's even more challenging when dealing with waste from burning trash and sewage. These wastes produce a nasty mix of chemicals and pollutants. We are talking about stuff like chlorine and organic pollutants. This stuff is hard to get rid of. Researchers have found a clever way to clean up this mess. They use something cal...
Imagine this: tons of peach waste from making fruit juice and compote. It used to go to waste. So why not turn waste into a high-quality product? Industrial waste makes up a lot of what we throw away. That's why every little bit of waste we can reuse and recycle helps our planet. It's all about sustainability. People realized that peaches, specifically the ones ...
Have you ever thought about what happens to the waste left over from mining? Phosphate mining, in particular, generates a lot of waste, including tailings and waste rock. These are usually stored in dams, but these dams can be unsafe. Brazil has seen many dam ruptures, which is why finding better ways to handle this waste is so important. One idea is to mix tailings...
Ever thought about turning your leftover fruit peels into something useful? Researchers have done just that by using pumpkin, papaya, and orange peels to grow microalgae. The goal? To produce biofuel, a special pigment called lutein, and something called biochar. This isn't just about creating new things; it's about doing it sustainably. The study found that the bes...
Believe it or not, trash can be a big problem when it comes to greenhouse gases. In China, people are turning to incinerators to deal with municipal solid waste, or MSW. Researchers decided to take a closer look at two incinerators in Qingdao. They found that Plant A released 56. 55 kilograms of CO2-equivalent per ton of MSW, while Plant B was a bit higher at 96. 73 ...
You might think compost is all about turning waste into something useful, but there's a hidden problem lurking inside: microplastics. These tiny plastic particles are sneaking into our compost from various sources like domestic trash, sewage sludge, and agricultural waste. Once they're in there, they mess up the compost's structure, making it less fertile and difficu...
Imagine turning your leftover fruits and vegetables into a clean energy source. That's what scientists are exploring with ultrasonic pretreated waste. They're mixing fruit and veg waste with sewage sludge and using anaerobic digestion to produce biomethane. This isn't just about reducing waste; it's about finding an alternative to fossil fuels. The researchers teste...
Composting is a smart way to recycle waste, but it often loses nitrogen, which is bad for the process. Biofiltration, a new method, can catch and change gaseous emissions into something useful. A recent study looked into how well a system that combines composting and biofiltration could keep nitrogen in distilled grain waste (DGW) compost. They used pre-composted DGW...
