What are your reasons?
I would rather
reuse free plastic than buy new anything.
I get used, lidded, plastic 10l paint buckets free from my
local paint shop.
Jute twine's handy, but old cotton shhets ripped into strips are great for garden tying. At season's end, they go in the
compost.
My plastic tarps were free, so same rules apply. There's 'old-school' canvas ones too...
As for food storage, glass jars are great. I don't buy the stuff that comes in them, but plenty of others are happy to donate their jars.
Nearly all come with resealabe lids, so they're really useful.
