A. Not in our opinion. There are even disposers that add enzymes every time that you use that disposer. From what we have read, bacteria grow naturally after initially being introduced (mostly by nature) into septic tanks, and no additional enzymes/bacteria need to be introduced. From our perspective, adding additional enzymes/bacteria each time seems like a waste of money and resources. One additional note, our Founder wishes to encourage you to use composting and not throwing all wastes down your food disposers. Save the Planet and recycle as much as possible.
