Waste

Cigarette ash could now have another use besides ... well, nothing (Photo: Shutterstock)

In a perfect world, cigarette waste simply wouldn't exist. Given that it does, though, scientists have explored a number of methods of repurposing it – these have included using compounds from cigarette butts to store energy, make shipping pallets, and rust-proof steel. Now, researchers have shown that cigarette ash can be used as a low-cost means of filtering arsenic from water supplies. It's a little ironic, as cigarette smoke actually contains a dangerous amount of arsenic.  Read More

The Energy Tower is a new waste-to-power incinerator in Roskilde, Denmark

Incinerators can't often be described as beautiful, but a newly inaugurated incinerator in Roskilde, Denmark, is just that. The main purpose of the Energy Tower is to generate electricity and heat. At night-time, though, glowing lights can be seen beneath its perforated façade.  Read More

A bacteria found in England that can survive in harsh alkaline conditions could be used to...

"Extremophile" bacteria have been found thriving in soil samples from a highly alkaline industrial site in Peak District of England. Although the site is not radioactive, the conditions are similar to the alkaline conditions expected to be found in cement-based radioactive waste sites. The researchers say the capability of the bacteria to thrive in such conditions and feed on isosaccharinic acid (ISA) make it a promising candidate for aiding in nuclear waste disposal.  Read More

Mushrooms grown in used diapers help reduce waste volume by up to 80 percent

While the contents of a diaper could easily be considered an environmental hazard by many, disposable diapers themselves pose a more significant problem for the environment. According to the EPA, the average baby will work their way through 8,000 of them before the underwear makes its way to landfill, where it takes centuries to break down. In an effort to reduce the problem, scientists at Mexico's Autonomous Metropolitan University, Azcapotzalco (UAM-A), have turned used diapers to the task of growing mushrooms.  Read More

It's an unfortunate fact that every day around the world, supermarkets throw out tons of food that has spoiled before it could be purchased. While it would be best if that spoilage could be avoided in the first place, British grocery chain Sainsbury's is taking what might be the next-best approach – it's about to start using that unsellable food to power one of its stores.  Read More

Martin Myerscough believes that little changes in the way coffee cups are produced could a...

Along with a timely hit of caffeine, takeaway coffee can deliver its fair share of environmental angst as the office trash can begins to brim with empty paper cups. But what if, instead of being carted off to landfill, these cups could be recycled up to seven times, much like newspapers and regular cardboard? According to UK-based inventor Martin Myerscough, a small difference in the way these cups are produced could significantly reduce the monumental waste generated by today's coffee-crazed society.  Read More

The Sangenic Nappy disposal system: when you're tired of dealing with other people's crap

Life can be cruel, folks. Just a few weeks ago I was road testing electric motorcycles, wind in my chest hair, livin' the dream. Then, in an instant, I became a dad – well, it was an instant for me, the missus might feel differently about it. Either way, here I am, reduced to writing a road test for a diaper bin. But a fine diaper bin it is, and I have resolved to attack this new topic with vigor and passion. Ladies and gentlemen, the nappy sausage machine.  Read More

Can garbage be used as an eco-material to construct a house? That's the intriguing premise behind the recently-completed Waste House project, which is believed by those involved to be the first permanent British building built almost solely from waste and recycled materials. Constructed at the University of Brighton's Grand Parade campus, the Waste House is an ongoing experiment which aims to prove, in the organizer's own words, that "there is no such thing as waste, just stuff in the wrong place."  Read More

Thanks to its extensive composting and recycling facilities, the city of Edmonton, Canada is already diverting approximately 60 percent of its municipal waste from the landfill. That figure is expected to rise to 90 percent, however, once the city's new Waste-to-Biofuels and Chemicals Facility starts converting garbage (that can't be composted or recycled) into methanol and ethanol. It's the world's first such plant to operate on an industrial scale, and we recently got a guided tour of the place.  Read More

Tomatoes are already found in soup, ketchup, and most Italian dishes, but researchers at Ford and Heinz may have discovered the secret sauce to making car parts from them. The companies' boffins are currently investigating the potential use of waste tomato peel for the manufacture of interior car parts, such as wiring brackets, and dashboard-based storage.  Read More
