Garbage at the Farmer's Market

There is a lot of garbage at the farmer's market. The top picture shows some of the vendor-garbage and the one below it shows the large number of customer coffee cups. It was a cold day and nearly everyone had coffee, but the waste is not congruent with the "sustainable" spirit of the farmer's market (as explicitly mentioned by the sponsors and, otherwise, implicitly evident in the market itself)

Is there a way to improve the garbage situation using more reusable or, at least, recyclable items?
