The great news is that BZT® Waste Digester is ridiculously easy to use! BZT® Waste Digester is packaged in either 1 lb. [454g] foil packs, or in a 20 pound [9.08kg] box. The product is a dry powder which is stirred into lukewarm water and poured directly into the drain or grease trap. It can’t get much easier than that!
