Sodium polyacrylate, recovered from industrial rejected diapers, is perfectly suited for making flood bags. Sodium polyacrylate absorbs more than 150 times its weight in water. A small amount of this material inserted in a permeable pouch provides a lightweight and easy to handle bag. Once in contact with water, the super absorbent polymer will absorb water and will inflate the bag, which will be used as a flood barrier. These bags are an improvement on the traditional sandbags used in these situations. Ten bags of sodium polyacrylate weigh 5 kg, whereas ten sandbags weigh 220 kg. People located in flood-risk area can easily store one hundred of these new “sand bags” in their homes, and one person can easily install the bags to protect their property.
These “sand-free sandbags” already exist on the market and Recyc PHP encourages people who want to acquire this innovative product to consult the following websites:
