Sh*t a brick

Taiwanese researchers say they’ve crafted a win-win situation in the discovery that sewage sludge can be used to bulk up construction bricks. The bio-bricks contain up to 30 percent sludge, which can come from either industrial slurry or the, er, human waste stream. Because the bricks are kiln-fired at 900C, all bacteria and viruses are destroyed. Plus the process seals in any heavy metals that might be present. Best of all, the researchers say, the bricks don’t smell at all. The team behind the discovery admits that people might need some convincing to live in such intimate contact with their past meals, noting that legal approval and public acceptance remain to be sought.

Global population says ‘Pass the chicken’

Meat-eating is on the rise around the globe, a trend that could raise the risk of animal disease spread across borders, the Food and Agriculture Organization of the United Nations (FAO) said this week in a document circulated at a meeting on meat and dairy products. Worldwide meat consumption is expected to grow by 2 percent each year until 2015 — the result of population increases, rising incomes, and the movement of people from rural areas to cities. “However, increased volume of trade and improvements in transportation, infrastructure and technology hold potential risks of spreading of animal diseases rapidly worldwide,” FAO warned.
