I have seen the cans side by side. Also front to back with smaller bins on the side for compost.

Are these custom? If so, you can make your trash cabinet multifunctional. Put the cans to one side, and have dividers in the extra space for things like bags, with a lid to keep trash from accidentally falling in.

You can do a false pullout in 6", which looks like it has an inset door, but the whole face frame pulls out as well.

In three inches you can do vertical storage for cutting boards and baking trays. Or you can do a pullout towel bar thingie.

We are just starting to use a trash pullout that is 12" and has a trash in front and recycling behind. 24" sounds like a large pullout solely for trash. Since these are custom, I just wanted to add that we asked the cabinet maker to put a solid barrier between the trash and the drawer above.

Very few manufactures make a 24" trash cabinet. Those that do call it a recycle center and it may have 4 bins to work with. Usually a 21" would be the largest.

I thought having the silverware above the trash was a little weird too. But, it really is the best option for it. The only other possibility is on the opposite stretch of the same counter, but that's in a corner which will be my prep space, and it's less accessible for others.

I read the suggestion here to entirely box-in the trash cabinet to contain odors. Also, my city has a great recycling system that basically takes everything except food scraps. I've taken to using a small trash under the sink for stinky organic waste. Wonder if I'll do the same in the remodel? I always wished for bigger recycling bins...

Still, 24"? I can't visualize it.

Have you seen these from Rev-A-Shelf?

It is meant for a 24" wide cabinet and it is called a recycling center. My trash out is from Rev-A-Shelf also.

Check out Richelieu for european options. We're going with a 15", but I seem to recall they had wider, with a drawer above.

if you don't mind using some of the under-sink area, i really liked the picture of analysisparalysis's under-sink garbage pullout. look under the heading "Fourteen months later...it's DONE!!! (Pics...and a thank you!)" -- the picture is toward the bottom. perhaps then you could use undersink for garbage and the other for recycle. it wouldn't be so bad to have cutlery above the recycle bin.

we considered getting a 24inch double garbage/recycle drawer but tried one out and decided that it would just be too heavy when full. but i don't have some hand/wrist issues-- so maybe it's fine for you.

I also think 24" would be unwieldy for a pullout that you would be using frequently. I haven't seen this, but could you use an 18" pullout, then use the extra six inches of space for open wine cubbies or something like that? You could also do tray storage there. (I don't have insets, so I am no entirely sure how much space would remain in a 6" tray cabinet, but the wine cubbies would be open, so you should be able to use the full 6").

This is the 24" pull-out I was thinking of. It has an automatic lid, and can be mounted under a drawer. Richelieu is the Canadian distributor, but should be available in the US somewhere.
