Fertilize the Land with Your Waste

Quite literally, an architect and professor in Stockholm Anders Wilhelmson has introduced the mobile disposable toilet in a bag.

The creatively named Peepoo is a disposable bag that can be used to collect faeces and urine which is then broken down by urea crystals – rendering waste into fertilizer.

Potentially useful in toilet-deficient neighbourhoods, I would suggest branching out to the camping market as well – since it may now be possible for campers to avoid the complicated task of digging a deep hole for a toilet, and instead dig a shallower hole just to bury the Peepoo.

Imperial College Unveils Degradable Plastic

There are probably a few dozen plastic-like replacements on the market you may have heard of. Now we can add Imperial College’s degradable sugar polymer based-on lignocellulosic biomass.

This guilt-free plastic, unlike other solutions on the market is not based upon corn or sugar beet but on the sugars produced from the breakdown of lignocellulosic biomass, or in other words cellulose, hemicellulose, and lignin found in wood byproducts, grasses, and some types of agricultural waste.

This means plastic produced via this method probably won’t affect the price and supply of food-based agriculture products – a significant issue that needs to be addressed before biodegradable plastic can be widely distributed.

Of course, it would be better if every one could forego all forms of disposable-ware. No amount of biodegradable items can compete with zero-waste production.

Printer: Without Ink, Toner or Paper

As the awkward language suggests, this may be a Google Translation of the original Japanese site. Or I could be completely wrong and they just had a lousy translator.

Anyway, this is the PrePeat RP-3100, a printer by the Japanese company Sanwa Newtech Co. Ltd. Sanwa claims this printer is able to print up to 1000 times on special reusable sheets. That’s right, why toss out that 50-page thesis draft when you can erase everything on it and reprint again, thus saving a few more trees plus handing in a waterproof draft every single time.

CrunchGear has a write-up and a video of the printer in action with links for purchase, while the official site has a cost breakdown of the PrePeat versus generic printers.
