Waste and recycling

In a stroke of ingenuity that could have proven handy during Hurricane Sandy, four teenage African girls have come up with a urine-powered generator.

Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, all 14, and Bello Eniola, 15, collaborated on the invention, which they claim generates one hour of electricity from one liter (about a quart) of urine.

The pee-powered product made its debut at Maker Faire Africa in Lagos, Nigeria, this week. A post on the Maker Faire Africa blog describes the generator's workings in the following words: … Read more

Your next pair of Levi jeans may include black trays, brown beer bottles, clear water bottles, and green soda bottles. The new WasteLess collection uses polyester fiber made from crushed plastic recyclables. The bottles are collected from municipal recycling programs around the country.

Both jeans and trucker jackets will be available. Plastic pants don't sound very comfortable, but the plastic parts only take up about 20 percent of the cloth. The recycled fiber is mixed with cotton fiber so you get a pant that feels like regular denim.… Read more

More and more these days, we're picking up drink bottles and plastic utensils crafted from corn rather than regular plastic. So, how about products made from agricultural waste and food scraps? Glad you asked. The Biobased Kidshouse from Dutch consortium BE-Basic is made entirely from natural materials such as agri-waste, tree bark, and potato peels.

The panels are made from compressed straw. The roof is waterproofed with vegetable oils. The electric sockets are where the potato peel bioplastic comes in. … Read more

What would you do for free Wi-Fi? Mexican Internet provider Terra has teamed up with ad agency DDB to offer free Wi-Fi in public parks to dog owners who clean up after their pets.

As seen in the absurd promo vid below, owners who deposit poop in the special bins in 10 parks in Mexico City will be rewarded with free Wi-Fi, broadcast through routers shaped like doggy bones.

The more you add, the more minutes you and everyone else gets. The bins seem to have a simple scale to weigh the poop, so they would likely still work if people put rocks or trash in them instead. … Read more

In a new twist on using waste for energy, Microsoft is designing a data center powered by biogas, the gas given off from landfills and other sources.

The company last week further detailed its Data Plant experiment, an idea to bring more reliability to its data centers and lower pollution from them.

Fuel cells would supply power to the data center and make it independent from the grid, said Christian Belady, general manager of Data Center Services in a blog post last week. In theory, having on-site power allows a data center operator to use the electric grid as bac … Read more

The Denver Zoo is rolling out a motorized rickshaw that has been converted to run on animal droppings. It might help save a bundle.

Imported from Thailand, the tuk-tuk is about 20 years old, but it has been given a new lease on life from engineers at the zoo.

The electric three-wheeler runs on gasified pellets made from animal poop, as well as trash produced by zoo visitors and staff.

A heater on the back of the prototype vehicle turns the pellets into syngas, which is used to generate electricity to power the tuk-tuk. … Read more

They say one man's trash is another man's treasure, and this certainly seems to be the case for Chilean artist Rodrigo Alonso.

Alonso is the mastermind behind the geeky chairs pictured above. They're made from pieces of old tech donated by Chilean recycling company Recycla.

The graphic designer creates the stools by pouring epoxy resin into a mold filled with the e-waste; the legs are made from cast aluminum. Alonso produces the chairs in limited editions, but he also takes special orders. Since no set of e-waste is alike, each piece is original and dyes can also be added to the resin to add color.

For Alonso, the project is more than just a piece of furniture or work of art. The chairs, which are called N+ew for No More Electronic Waste, is also about recycling e-waste. Though consumer electronics companies are slowly becoming more eco-conscious and more recycling programs are being put in place, the amount of e-waste is still expected to rise exponentially by 2020, especially in developing countries. … Read more

When electric Ford Focuses start rolling off the assembly line in March, some vehicles will incorporate recycled plastic bottles tossed away at CES.

The new EV will use Repreve seating material made by Unifi. Repreve is a blend of post-industrial fiber waste and post-consumer waste such as the plastic water bottles made of polyethylene terephthalate (PET). Each electric Focus will have the equivalent of 22 plastic bottles in its interior, and the strategy is expected to divert 2 million post-consumer plastic bottles from landfills.

If you're attending either the 2012 Consumer Electronics Show in Las Vegas or the 2012 … Read more

The conveyor belt of new mobile phone releases has created a stream of revenue for eRecyclingCorps.

The Irving, Texas-based startup today raised $35 million from Kleiner Perkins Caufield & Byers to expand its phone buyback services.

eRecyclingCorps, which is now used by at 3,000 Sprint and 500 Verizon outlets, lets consumers check the value of a phone they no longer want from a Web site and get a credit while in the store. A consumer can also use the application from home and mail the phone for a credit, although the company considers an instant rebate more appealing to … Read more
