It bothers us that we use styrofoam cups and plastic spoons to serve the soup and drinks on the street. Styrofoam is made from a non-renewable resource and is not biodegradable or recyclable. It is cheap, however, so that is what we use.
Now there are alternatives that are compostable; cups made from sugar cane fiber or potato starch and spoons made from potato starch. They cost more, but I think it is worth it, if we can continue to address oneproblem without exacerbating another one. Of course, this means I will be asking for more money as the non-offending spoons and cups will cost about $50 more per month.
I do have hope that the costs will come down as these products become more widely used and commonly available.
