Each patented Deterra pouch contains a water-soluble inner pod containing MAT12® activated carbon. Once the pharmaceuticals are placed in the pouch, warm water is then added, which dissolves the inner pod, releasing the activated carbon. The warm water will also help dissolve pills and draw the drugs out of patches. Made from environmentally sound materials. Packaging is USDA certified, 54% biobased and has received the I’m green™ plastic certification from Braskem.
