Thirsty Planet

"Each of us can make a difference if we first consider the water implications of our lifestyles and the water footprint we are leaving behind"

"Rice farmers in the region are now also saving water by a practice known as 'wet and dry' irrigation"

"The industrialised world is quick to point its finger at agricultural producers, blaming them for water woes, but it is our food habits that drive the problem"

Green Chips

In a fine example for a large company with a solid green stride, Sun chips, has announced that by 2010, the company will start to sell their snacks in compostable packaging. The new bag is made of a plastic from renewable, plant materials (PLA) and you will be able to compost it in your home compost pile, after you eat chips, of course.

Given the fact that composting is largely on the rise, and is increasingly common in the U.S., the promise of a fully compostable bags is indeed compelling.

The bags are made from polyastic acid or PLA, a unique polymer. In the press release from Sun Chips:

PLA is produced from lactic acid. Lactic acid is made from dextrose by fermentation.
Dextrose is made from starch and starches from carbon dioxide and water. Because it is with plants that grow every year instead of oil (millions of years to form) the impact on greenhouse gases is much lower.

The studies, based on the new bags to show that they compost in aerobic and anaerobic conditions in 12-16 weeks with temperatures above 55 degrees F. Of course, independent studies not yet be made on the bags because they are not on the market for a another year - so we have these results at face value. In other words, these bags are truly 100% biodegradable? Or are tiny particles of PLA will remain in your compost pile, and eventually found their way into the earth?

If not, this is a big step in the greening of product packaging.
