Waste

The toilet trike will hit the Japanese roads in the coming days, making its way from Kyush...

If you think this smells like a PR stunt, you're right. In an effort to raise awareness about bathroom emissions and water savings, Japanese toilet manufacturer TOTO has created the Toilet Bike Neo Project ... yep, it's a road-going, three-wheeled toilet fueled by "biogas" generated from the toilet waste.  Read More

Researchers have created an efficient new thermoelectric nanomaterial, that could be used ...

Virtually all electrical devices and industrial processes create heat as they operate, which is typically wasted. In the past several years, various thermoelectric technologies have been developed to address that situation, by converting such heat into electricity. The ideal material for the purpose would be one that has a high electrical conductivity, but a low thermal conductivity – that way, it could carry plenty of electricity without losing efficiency through overheating. Unfortunately, electrical and thermal conductivity usually seem to go hand in hand. With some help from an ordinary microwave oven, however, researchers from New York’s Rensselaer Polytechnic Institute have created a nanomaterial that appears to fit the bill.  Read More

A new technology is able to convert paper mill waste into bio-foam (Photo: P199)

In a world increasingly concerned with waste, the smart manufacturers are identifying ways of utilizing the by-products of manufacturing and creating two products from one process. One example – a graduate student in agriculture at the Hebrew University of Jerusalem has developed a way of creating foam from the waste from paper mills, radically reducing waste from paper production and creating two products that are highly valuable and in demand.  Read More

A mock-up of an industrial-scale version of The Muncher, a prototype system that rapidly c...

A number of cities around the world now sort their municipal trash, diverting organic matter into giant anaerobic composters that turn it into nutrient-rich soil. Such systems can be very expensive, however, and have a large physical footprint. The composting process can take as little as 14 days, or as long as one year. Nevada-based company Ecologico-Logic, however, has created an alternative system, called The Muncher. Not only is it relatively small, but its makers claim that it can convert organic waste into mulched and liquid compost in less than an hour.  Read More

Standing around, sorting debris from construction or demolition projects for recycling ... it probably isn't anyone's idea of a good time. Given the risks posed by sharp or heavy objects and airborne particles, it's not a particularly safe way of making a buck either. That's where, perhaps someday soon, ZenRobotics' Recycler autonomous waste-sorting robot arm will come into play.  Read More

LED light bulbs are becoming increasingly popular with designers and consumers of green technology, as they use less electricity, last longer, and emit more light on a pound-for-pound basis than traditional incandescent bulbs. However, while it may be tempting to look at them as having solved the problem of environmentally-unfriendly lighting, researchers from the University of California would advise against such thinking.  Read More

The Ferrator is a device that produces ferrate, a type of iron particle, to treat waste- a...

Ferrate is a type of supercharged iron particle, in which iron is in the plus 6 oxidation state – it’s also known as Iron (VI). That might not interest you, but perhaps this will: it can be used as an environmentally-friendly disinfectant in water treatment applications, reportedly outperforming stand-bys such as ultraviolet light, hydrogen peroxide, and chlorine. So, why isn’t it in common use? Unfortunately, it’s proven too expensive to produce, package and transport. Ferrate Treatment Technologies (FTT), however, claims to have addressed that limitation with its product, the Ferrator.  Read More

The Odourbuster mounts on an existing toilet, and uses a fan to draw odors down into the s...

Nobody likes the smell of a just-used bathroom – and no, we don’t mean a bathroom in which someone has just bathed. That’s one of the reasons bathrooms have ceiling extractor fans, although installing the wiring and ducting for such hardware is a hassle that it would be nice to avoid, if possible. The Odourbuster is an invention that reportedly does away with the need for a fan, by taking those nasty odors and sending them where everything else went – down the toilet.  Read More

The simplehuman sensor can is a 'touchless' garbage can that reacts to human activity

Of all the things we expected to see on display at CES in Las Vegas, a garbage can was not one of them. Nonetheless, amongst the tablet computers, 3D camcorders and iPhone apps, there sat the simplehuman sensor can. Like some other “touchless” garbage cans, its built-in sensor detects when someone is nearby, causing the can to obligingly open its lid. What makes it special – perhaps – is the company’s claim that the can’s “multi-sense” technology can adapt to what the user is doing.  Read More

Poo-Gloos (Bio-Domes) prior to submersion in a sewage lagoon

Poo isn't something generally talked about in polite company but like it or not, all of that human waste has to go somewhere. In smaller rural communities, it usually goes to wastewater lagoon systems; the alternative is mechanical treatment plants which process waste far more quickly but are expensive, labor intensive and often use chemicals. Enter the "Poo-Gloo," or Bio-Dome as it is officially known – an igloo-shaped device that can reportedly clean up sewage as effectively, but far more cheaply, than its mechanical counterparts. The Poo-Gloo, developed by Wastewater Compliance Systems, Inc., uses a combination of air, dark environment and large surface area to encourage the growth of a bacterial biofilm which consumes the wastewater pollutants. It is claimed that Poo-Gloos can treat pollutants just as quickly as mechanical plants while operating at a fraction of the cost – hundreds of dollars a month rather than thousands – and can be retrofitted to existing lagoon systems.  Read More
