I have a plastic bin with a charcoal filter that I keep under the sink and use when the weather sucks or when I'm just too lazy. Otherwise I walk out to the compost bin with a plate or bag when I'm cleaning up. Even a day or two under the sink, stuff gets nasty. It's best just to deal with it right away. It would be nice to have a hole in the counter to just scrape stuff into, but I can't imagine how that would really make things easier overall. You still have to take the stuff out, so the receptacle would have to be easy to remove. That would mean pulling it up through the counter top. Climbing under the counter to unscrew it would be annoying.
