Currently I'm looking into the issue of deposit return systems. Usually they are quite effective in keeping addressed items out of the environment, so I wonder why they are not expanded to many more products, such as food packaging in general.
Are there examples of countries (or regions/states) having implemented deposit return systems for products besides beverage containers?
I'm referring to cheap products typically consumed in large quantity (e.g. food packaging), not more valuable products that might have such a system implemented already (e.g. car tyres, electrical appliances).
