Banana peels don't get a lot of respect. Though we here at Shots have never actually heard of anyone slipping on one, it seems they're stuck in the cultural lore as a nuisance, or even a hazard.

But a Brazilian researcher, who also happens to be a banana lover, has taken an interest in the lowly banana peel and is helping to remake its image. The banana peel, it turns out, can take water dirtied by heavy metals from mining operations or other activities and turn it to clean drinking water.

Groovy, man.
"What he found was that banana peels contain nitrogen, sulfur and organic compounds such as carboxylic acids. Castro was especially pleased to find these acids because they can bind with positively charged metals that leach into rivers from industrial operations.

To test the peels, Castro and his colleagues chopped up and dried a bunch of them and mixed them with water from Brazil's Paraná River, which was polluted with copper and lead. The peels performed as well or better than many typical filtering materials, like silica or carbon. What's more, the peels are a cheap waste material. Castro found they could be used up to 11 times before they stopped working as purifiers."

But what do you do with them when they are used up? No good for compost anymore. :-

surely you can use them for something else? and sounds like you wouold be solving 1 problem but just causing another


Not if you consider the previous filtration method would also generate waste material which would have to be disposed in some safe fashion.
