My employer provides snacks to employees and generally uses compostable plates, cups, and utensils. However, a significant portion of the waste stream comes from the wrappers for things like chips and cookies. If my employer wishes to provide these kinds of snack foods, how can they get the attention of manufacturers of these to provide alternative packaging which is compostable?
The biggest cookie company in NZ (Cookie Time) started off by selling its cookies without packaging by providing large glass jars to store them (to be placed on a shop counter). It would very easy to provide some tongs and paper bags to reduce mess when handing them out. You might find a business that can provide the cookies in this way.
It's probably easier to find businesses using sustainable packaging already rather than trying to get a large business to change. When big businesses see small businesses thriving thanks to a particular quality, they often imitate it, so you can make a difference.
Alternatively, if you could create a large enough demand for a particular product (such as forming a consortium of like minded businesses), then it might have enough influence to get a small food business to change their packaging.
