How do you model litter? What do you use?

What era?
Seriously there’s been some discussion about this (I guess there’s been discussion of everything at some time or another), and it has been said urban areas in the '60s had more litter than today, use chopped up transculent rod for bottle ends, spray some (neatly) cut plastic rod for cans (predominately white or silver), some cut up squares of thin paper for newspaper, wrapping etc. (use a chisel blade if need be, on a stack of paper).
On my (yet undetailed) modern-era layout, I am saving up litter, mostly trimmings from assembling kits (blobs and bits of dried putty - painted white or red look like fast-food wrappings, pieces of trimmed styrene ends painted up become boxes, less cans around (recycling laws), but the pieces of transculent rod now represent plastic bottles, so they don’t usually have jagged edges (cut them square), paper that I blot my paintbrushes & stirring rods on, get blobs of all sorts of different colors on them, cut those up and they represent all kinds of discarded wrappings and waste paper. Somebody here (or on some forum) recommended a way to get nice discarded tires (for dumping in empty lots), but I can’t remember it, dang it - I do remember reading about putting together some thick styrene in a ‘oblong cube’ (rectangular solid - whee), drilling a big hole in the middle, adding a little styene strip door opened over the how, and a strip in back, paint it white (interior of the hole grey), paint the thin strip black, weather it up and bang - discarded washing machine (modify plans for discarded dryer, oven, fridge, etc.).
Don’t spend much time creating this litter, even a few seconds a piece can be too much (except as part of a detailed ‘scene’ - such as the washing machine for example) - try to use scraps you generate when building other things (as I said, small blobs of dried putty generated when patching seams look wrinkled and rounded - perfect for scrunched up wrapper
