Using a garburator and landfill sites to dispose of your organics are bad ideas.
Many cities, and the Canada Mortgage and Housing Corporation, recommend that people on septic systems avoid using a garburator because it will put too much organic waste into your tank. This means you’ll have to pump out your septic more often, which will increase your costs. Not only that, but when initially designing a new septic system the drain field sizing will have to be larger to support the Biochemical oxygen demand (BOD) (also called biological oxygen demand) is the amount of dissolved oxygen needed (i. e., demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period. This all means a much greater cost to your septic system and also on maintenance.
I recommend composting. You can try backyard composting, or indoor composting.
Vermicomposting is ideal for small spaces and can be done indoors—under the sink, in the garage or in a spare room. Discard organic matter generated in your kitchen—like banana peels—by feeding it to worms. The result is a fertile mixture of decomposed food scraps and worm poop.
Most Canadian cities also have local vermicomposting champions or organizations that sell worms and worm bins or will show you how to build one, like the Compost Education Centre in Victoria.
A second option is bokashi composting. It’s different from outdoor composting because it turns food scraps into fertilizer via fermentation. Bokashi means fermented organic matter in Japanese. A select group of microorganisms anaerobically (without air) ferment the organic waste. Apparently, they will also break down things like meat, fish and cheese.
Another idea, if you live in the countryside, is to canvass your neighbours about setting up and investing in an animal-proof composter. Perhaps it could live near a community garden, or maybe your city or town could start a composting location on public property.
