In the United States, many of us automatically think of an InSinkErator, which is a brand of electrically run mechanical grinder of food which then flushes it all down the drain for someone else to deal with. It is attached to a kitchen drain and mounted underneath.

I remember when i was growing up, we had one. There was always a good respect for its power – keep fingers and spoons out of them! However, as an adult, i’ve never had one and honestly never missed it. Now, i wonder why one would ever need this type of garbage disposal. Natural processes are excellent at garbage disposal – especially food scraps and other organic stuff.
But, garbage disposal is actually just a term that describes various ways to dispose of garbage. Your location and occupation often determines your definition of garbage and how you may dispose of it. If you have too much; it might be time to make a plan to reduce, reuse, repurpose, recycle, repair.
In my world, food scraps are not garbage – either they are composted, (i’m lazy and just throw them out on the garden spot to break down over time, or if i’m really energetic, i may get a spade and bury them) or i feed them to our pastured laying hens (chooks), but chicken scraps go to the dog – (i never feed chicken bones and such to chickens – it just seems wrong). Fruit from fruit trees almost always produce far more than i’m willing to preserve in some fashion, so the extra is allowed to fall, rot, and provide fodder for soil microbes which in turn provides fertilizer for the tree.
There are some amazingly attractive kitchen sized compost bins available. Here are some on Amazon, but i’ve never tried any of them. Do some research before purchasing – you sure don’t want smell and/or flies in your house!
But, by and large, we have very few scraps. Leaves from broccoli and cauliflower, for example, make awesome replacement for celery or other similar greens. This goes for nearly all greens attached to vegetables. The core from tomatoes go to the chooks; they love them! Beef fat goes to the chooks for extra protein they need when bugs are in short supply outdoors. (As an aside, if you are buying eggs that are labeled as vegetarian raised chickens, the label is either a lie or the hens are in confinement – either crowded in a floored building or in a cage.)
There is a lot of hue and cry about being ‘green’, but as is usual, the ones crying the loudest are often the ones living the least ‘green’ and the biggest wasters of natural resources. They are the crowd who shout ‘do as i say, not as i do’ while they manipulate regulations to suck cash out of your pocket and put it in theirs.
We can all do better at managing resources – we are, by and large, a wasteful country because we are blessed with so much abundance.
