Garbage disposas have l indeed had environmental significance. Probably the
best way to answer is to provide a list of "good" and "bad" contributions
of the garbage disposal as follows:
- Reduced urban city and landfill waste of organic material (which
rots and smells, attracts flies, insects, rodents, and lends itself to
- Some convenience in cleaning the dishes and food preparation.
- New commodity invented.
I'm not sure how you could measure significance, except to
chronologically correlate number of disposals in a selected city to the BOD
load on the WWTP, while eliminating straight population increase.
Hope I've helped some.
- Increases the
Biological Oxygen Demand load to municipal
wastewater treatment plants, thus increasing operation and maintenance
costs in these plants (probably why NYC is slow in approval).
- Has made rural and other folks lazy- most everything that goes down the disposal
could be used as either some type of animal feed (esp. chickens and pigs)
or would be great for composting. Rural disposals are ridiculous. They
also overload limited septic systems.
- Use electricity and water resources that would not be otherwise used.
