Waste

A length of the paper-based bricks being extruded

Paper waste has already been used to create things like foam and batteries – now, a team of researchers from Spain’s University of Jaen are making bricks out of the stuff. Although the finished products still need a little tweaking before they're ready for prime time, they could ultimately give traditional bricks a run for their money.  Read More

A team of researchers at Rice University has developed a new technology that uses light-absorbing nanoparticles to convert solar energy directly into steam. Even though it is already significantly more efficient than solar panels at producing electricity, the technology will likely find its first applications in low-cost sanitation, water purification and human waste treatment for the developing world.  Read More

The Zero Waste Twist Dispenser is a prototype container designed to let consumers use ever...

Does it bother you that you can’t get all of the liquid out of the bottom of a hand-pump-equipped container? Well, the folks at Pack Flow Concepts think that it should. According to them, such containers don’t dispense up to 15 percent of the ketchup, shampoo, soap or other liquid stored inside of them. That’s why Pack Flow is developing the Zero Waste Twist Dispenser.  Read More

A cheese-powered dragster designed by researchers at Utah State University (USU) set a new speed record for a vehicle of its type, reaching a shade over 65 mph (104 km/h) at the Utah Salt Flats Racing Association's 2012 World of Speed event in September. No prize Stilton was wasted in the pursuit of glory however, as the vehicle runs on yeast biodiesel derived from the industrial waste of cheese production.  Read More

Bog in a Bag is a portable way to 'use the bathroom' anywhere

Have you ever tried to poop in a small plastic bag? Outside of a childhood dare or college prank, the answer is probably an emphatic NO. In certain backcountry and river camping scenarios, however, that's exactly what you're expected to do. The Bog in a Bag gives you a better way of doing that dirty work.  Read More

The Bokashicycle Food Waste Pulverizer is designed to consolidate commercial food waste, a...

Businesses such as restaurants, grocery stores and farms are known for generating a lot of food waste. Not only can that waste take up space and attract vermin in landfills, but it can also be costly for those businesses to dispose of. That’s why Nevada-based Bokashicycle introduced a new product this week, the Bokashicycle Food Waste Pulverizer. The machine “shreds, rips, bruises and pulverizes” food waste, allowing more of it to fit within a receptacle, and preparing it for easy composting.  Read More

A chemical engineer has created a 'food biorefinery' that converts used coffee grounds and...

Every year, the individual stores that make up Starbucks Hong Kong produce almost 5,000 tonnes (4,536 tons) of used coffee grounds and unconsumed bakery items. As it stands now, all of that waste is incinerated, dumped in a landfill, or composted. In the future, however, it may be used to produce a key ingredient in laundry detergents, plastics, and many other items. A recent experiment showed that it can indeed be done.  Read More

Collecting plastic nurdles with the 'Nurdler'

You may have heard about the huge floating islands of garbage swirling around in the middle of the Earth's oceans. Much of that waterlogged rubbish is made up of plastic and, like Electrolux with its concept vacuum cleaners, U.K.-based Studio Swine and Kieren Jones are looking to put that waste to good use. As part of an ambitious project, they’ve come up with a system to collect plastic debris and convert it into furniture.  Read More

Bill Gates weighs evaluates the Toronto Toilet at the Reinvent the Toilet fair in Seattle

In an effort to improve conditions for the more than 2.5 billion people worldwide with no access to safe sanitation, the Bill & Melinda Gates Foundation last year awarded grants totaling US$3 million to eight universities to reinvent the toilet. At the two-day “Reinventing the Toilet” fair held in Seattle this week, where Bill Gates was on hand with 50 gallons (189 l) of fake feces made from soybeans and rice to put the various designs through their paces, a California Institute of Technology (Caltech) team claimed first place for their solar-powered toilet.  Read More

A Japanese inventor has built a waste basket that tracks garbage tossed in its general dir...

We've all done it: you toss a piece of trash at a nearby waste basket only to have it ricochet off the edge, forcing you to make that shameful walk to go pick it up and drop it in carefully. You only have your own hand-eye coordination skills to blame, but if you think about it, shouldn't catching trash be the garbage can's job? That certainly seems to be the thought process that led one Japanese inventor to construct a smart trash can that tracks garbage tossed in its general direction and then moves across the floor to catch it.  Read More
