The University of Colorado's solar toilet

A toilet project that addresses environmental and health concerns was unveiled in Delhi, India this month. Around 2.5 billion people in the world lack proper sanitation, and it’s with those people in mind that a team at the University of Colorado Boulder has designed a self-contained, solar-powered, waterless toilet. It was made possible with a grant from the Bill & Melinda Gates Foundation.  Read More

As with every major city, New York creates a huge amount of waste. Disposing of it requires a variety of environmentally damaging processes, such as landfill and transportation. To try and minimize the impact of waste disposal, Present Architecture has proposed a series of composting islands along the city's waterfront.  Read More

The closed-system Blue Diversion toilet is designed for off-grid use

Two years ago, an off-grid closed-system toilet known as the Diversion won an award at the Bill & Melinda Gates Foundation's "Reinventing the Toilet" fair. Created by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and now called the Blue Diversion, it recently also won the title of Most Innovative Project (Europe/West Asia), as bestowed by the International Water Association. So, what makes it so special? Well, for one thing, the same water that flushes it is subsequently used in its hand-washing sink.  Read More

Iota was designed as a final-year project at the UK's University of Huddersfield

It took thousands of years for the humble toilet to evolve into the model we use today, but there's always room for improvement. With this in mind, Gareth Humphreys and Elliott Whiteley produced the Iota: a folding toilet concept that's smaller and more efficient than the typical loo.  Read More

Don't throw those eggshells away – they could be made into ceramics (Photo: Shutterstock)

According to the US Department of Agriculture, every year approximately 455,000 tons (412,769 tonnes) of discarded eggshells must be transported and disposed of in the US alone. Now, however, scientists at the University of Aveiro in Portugal have developed a method of using such eggshell waste in the production of ceramic goods.  Read More

'If we can't comprehend the issue then we don't feel anything, therefore we don't act. I'm...

Around the world there are hundreds of millions of discarded mobile phones lying around in drawers and boxes, displaced by the bigger screen or better camera of the latest version. But truth be told, even if we were talking about hundreds of billions it would be unlikely to elicit a much different response, because ridiculously big numbers are ridiculously big numbers, right? Seattle-based photographer and activist Chris Jordan is on a mission to make these measures of consumerism manifest through visual art and, as he explained to Gizmag, bridge the disconnect between our mass consumption and its largely invisible consequences.  Read More

Scientists have succeeded in converting plant waste to gasoline (Photo: Shutterstock)

By now, most people have at least a passing knowledge of biodiesel – it's diesel fuel made from plant or animal oils, as opposed to the more traditional and less eco-friendly petroleum. While it's a good choice for people with diesel-powered vehicles, those of us with gas-burning cars haven't been able to get in on the action ... although that may be about to change.  Read More

Goodwill of San Francisco has launched a smart donation bin called goBin that aims to make donating old clothes and other textiles a snap. Instead of having to make a regular trip to a Goodwill store, the bin will allow residents of apartment towers to donate their stuff from the comfort of their buildings. Developed in collaboration with the global product strategy firm, Frog Design, the high-tech textile-recycling bin is expected to help the city's environmental department reach its goal of making San Francisco a zero waste city by 2020.  Read More

This artificial muscle-driven heart pumps human urine and will be used to power the Ecobot...

It's strange to wrap one's mind around the idea of human pee powered robots, but that's exactly what a group of UK researchers are attempting to create. Mimicking the human heart, their latest innovation is a heart pump with artificial muscles that aims to deliver human urine to their latest generation of Ecobots – a self-sustaining robot that runs on all manner of waste matter collected from its environment.  Read More

Vancouver's cigarette butts are being used to manufacture shipping pallets, among other th...

What can you say about cigarette butts? They instantly make wherever they are look seedy, they don't biodegrade, plus they're highly toxic to aquatic organisms. It turns out, however, that they are good for something. The City of Vancouver and TerraCycle Canada launched a first-of-its-kind pilot program this Tuesday, in which the butts will be collected for recycling.  Read More
