In sink garbage disposals are very convenient, but not the most environmentally friendly way to dispose of food scraps. Composting is ideal, but no one wants to leave scraps in the kitchen and only get around to taking them outside when they smell bad enough.
So, let's keep the handy garbage disposal
unit, but reroute the plumbing to a dedicated compost line. Like a grey water line, it runs parallel to the regular sewer line, collecting the fluid for reuse. In this case, the food sludge is directed outside to the compost pile, draining the excess water.
This would be especially useful in cities, where an entire apartment building can have a community compost pile. Now people can use their garbage disposal like always, taking comfort in knowing they're destroying the environment a tiny bit less.

I do take out the compost, as I live in a rural area, but this a great alternative for those who have garbage disposal units. I would also suggest they change the name to promote the composting! Compost disposal unit makes more sense, as you are not to throw *garbage* in there anyway. It's kind of funny or sad, but in other, poorer countries, all those carrot shreds, onion skins, etc. go into a big pot of soup or stew! |

I like the name, [xandram]. I take out the compost myself too. Yesterday the pile happened to be buried under snow and blocked by other obstacles, which led me to the idea for laziness. |

Even given the use of kitchen scraps for stock, there are plenty of things which go into the compost, though thanks to [UnaBubba], we no longer throw coffee grounds away. However, stock remnants persist and, being cooked, are supposedly unsuitable for composting because they would encourage rodents (or possums? Dunno, ask him). Nevertheless we compost cooked scraps. The biggest problem is the quantity, particularly in the winter. |
|
| |
why don't you throw coffee grounds away? |
|
| |
Because they can be used for dyeing and making body scrub. |

Well, I'm not much of a cook though I do enjoy the practice and occasionally the results, but onion skins are only used as a dye: they have no real nutritional value. And carrot shreds are non-existant 'round here since carrots get scrubbed, not flayed. I'm still looking for a use for carrot-greens [edit] though a possible allergen they can be eaten, or used in making stock. |

rodents are part of the ecosystem too.
not composting cooked leftovers is just silly. |
|
| |
I think one issue is that cooked material rots rather malodorously. |
|
| |
//rodents are part of the ecosystem too//
... as are snakes, scorpions, wolves, etc.: all sorts of things you don't want hanging 'round your door demanding a handout. |

I'd like to start composting stuff, but there's this fox that keeps leaving great big poops on our back lawn and I'm worried that if I go to the effort of trudging down to the end of the garden to throw out the scraps, I'll end up trudging in the left-behinds of the fox on my way back in. Any fox/cat deterrent ideas to help promote composting?
In the absence of that, this is a jolly good idea.[+] |

//garbage disposals are very convenient, but not the most

|
| |
Is that true? I presume the minced gunk goes into the
sewerage system, and thence to a sewage treatment plant
where it goes into a digestor along with all the other ...
stuff. |
|
| |
I'd always assumed that the end products of treatment are
relatively clean water, and some sort of composty gunk.
Where does it all go? |
|
| |
I like this idea. I posted it once under the name In-sink-composterator in '03 I think it was. It was deleted.
<shrugs>
I still think it's awesome and plan to incorporate the concept into the dream home I might finally get to build someday. |

The ultimate goal for food scrap disposal is the Mr.Fusion reactor that powered the DeLorean in Back to the Future. |

// onion skins are only used as a dye: they have no real nutritional value // |
|
| |
I wouldn't say that was an internally consistent statement. If something appeals visually, for instance if it's coloured, it's more likely to be eaten. On the other hand, if you're starving that's unlikely to be an issue. |
|
| |
Does any part of the onion have nutritional value? |
|
| |
The steak part of the onion is rich in protein. Or maybe I'm
thinking of steak-with-onions. |

Since you would have a good amount of water, why not
send it to a biodigester <link>. No holding tanks for
//collecting fluid for reuse// and no rodents in the
compost pile. Also, a simple PVC ball valve would allow
rerouting the waste with a minimal amount additional
plumbing. This seems far over-engineered. Or, did I just
take too many meds today? Still a [+] in my book for an
idea that encourages composting and makes an effort to
make it easier. |

Grumpy man. Where do you live that there are foxes?
BTW, you gave me an idea. |
