5 Free Apps to Swap, Share and Sell Your Extra Stuff

Read the full post on Shareable.

The average American spent $82 per day on consumer goods last month. It’s safe to say that we’re in the grips of a powerful consumption habit.

Not surprisingly, this creates a gargantuan amount of waste. Where does all that stuff go when we’re finished with it? Too often, the landfill. In 2012, Americans generated nearly 251 million tons of trash. That’s over 1,500 pounds of trash per year for every man, woman and child in the U.S.

Sharing can not only keep tons of trash out of landfills, it can save us tons of money. If Americans cut their daily consumer goods habit by half, they could save an estimated $15,000 a year.

There’s never been a better time to share or tools to do it. Below are five apps to help you swap, share, and sell your extra stuff like a pro.

Abstract: Embedding of mammalian cells into hydrogel scaffolds of predesigned architecture by rapid prototyping technologies has been intensively investigated with focus on tissue engineering and organ printing. The study demonstrates that such methods can be extended to cells originating from the plant kingdom. By using 3D plotting, microalgae of the species Chlamydomonas reinhardtii were embedded in 3D alginate-based scaffolds. The algae survived the plotting process and were able to grow within the hydrogel matrix. Under illumination, the cell number increased as indicated by microscopic analyses and determination of the chlorophyll content which increased 16-fold within 12 days of cultivation. Photosynthetic activity was evidenced by measurement of oxygen release: within the first 24 h, an oxygen production rate of 0.05 mg L−1 h−1 was detected which rapidly increased during further cultivation (0.25 mg L−1 h−1 between 24 and 48 h). Furthermore, multichannel plotting was applied to combine human cells and microalgae within one scaffold in a spatially organized manner and hence, to establish a patterned coculture system in which the algae are cultivated in close vicinity to human cells. This might encourage the development of new therapeutic concepts based on the delivery of oxygen or secondary metabolites as therapeutic agents by microalgae.

Apple swings for the fences with $848 million solar deal

Read the full story in GreenBiz.

In October, Apple‘s Vice President of Environmental Initiatives Lisa Jackson told a GreenBiz audience that the Silicon Valley tech giant is “swinging for the fences” on sustainability and renewable power.

On Tuesday, Apple made good on Jackson’s promise — and then some — by announcing the largest commercial purchase of solar power ever with an $848 million deal with First Solar to buy the electricity generated from a huge solar farm the equipment firm is building in California.
