Recycling

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

Researchers have combined materials derived from alfalfa and pine resin to create a recycl...

Thanks to their high power ratings and relative reliability, lithium-ion (Li-ion) batteries are an efficient and reliable source of power, widely used in modern electronic equipment. On the downside, however, expired Li-ion batteries are also difficult to dispose of, with their potentially toxic content and the complex methods required for their recycling. Researchers at Uppsala University’s Ångström Laboratory think that they may have a solution: combine the salvaged remnants of a Li-ion battery with completely organic materials derived from alfalfa and pine resin, to create a recycled biomaterial Li-ion hybrid battery.  Read More

Carbon black from tires reportedly makes a better anode material than the traditional grap...

There may soon be a new use for discarded tires ... besides turning them into mattresses for cows, that is. Researchers from the US Department of Energy’s Oak Ridge National Laboratory have devised a method of harvesting the carbon black from them, and using it to make anodes for better-performing lithium-ion batteries.  Read More

By measuring a plastic item's fluorescence half-life, it's possible to tell what kind of p...

If you've ever had to separate different types of plastic for recycling, then you'll know how much it slows down the recycling process. Now, imagine how much harder it is for staff receiving huge amounts of unsorted plastic at municipal recycling plants. New technology developed at Ludwig Maximilians Universitat in Munich, however, identifies plastic types automatically.  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

Matterbetter is seeking ideas for new uses of the Russian Typhoon nuclear submarine

Reappropriating structures or spaces for new uses is a common occurrence. Sydney's Goods Line and Battersea Power Station are both the focus of such projects. Now, architectural firm Matterbetter is asking for submissions to reimagine perhaps the most unusual thing yet: a Russian nuclear submarine.  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

Researchers at Ford and Heinz are developing a method of manufacturing car parts from toma...

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

Unwanted toilets may soon have new life, as a component of cement  (Photo: Shutterstock)

An international team of researchers has discovered a potential new use for discarded toilets, along with other ceramic waste such as basins, stoneware and bricks. It turns out that they can be made into a more eco-friendly form of cement.  Read More

The shipping container-based terminal is located in Spain's only river port, based in Sevi...

In order to accommodate the growing number of cruise ship passengers who regularly disembark at the Spanish Port of Seville – the country's sole inland port – a new cruise ship terminal has been built using shipping containers. While they aren't always the best building material for every situation, in this case they appear to have proved a good fit.  Read More
