Yes - but with caveats. Solids like meat scraps and fruit pulps(not peels!) can be liquified with septic tank additives. It's a good idea to use these every month(I set a recurring reminder on my phone). The caveat is substances like fruit peels, coffee grounds, oils, or the gristle portion of meats. These don't break down with the enzymes, and just float(or sink) in your septic tank until you have it pumped.
