The Sound Green

I went to the Vegfest at Seattle Center yesterday and I noticed that people are not very clear about what are compostables, what are not. There were containers designated for general trash and compostables. However, at the end of the event, the trash was all mixed up and nobody seemed to care to sort their trash before tossing them into the bins. Then I began to wonder how well-educated people in Seattle on the concept of composting trash are. How do people learn about the types of trash that can be composted?  Do people just sort out their trash at home and care less when they are in public events or places? How are some effort that event planners made to help sorting out the type of trash?  What happens after the garbage is collected by workers from waste management companies?  And of course the very basic question, what are compostables and non-compostables?

Here are some pictures of the trash bins at the Vegfest:

This is a bag that collects compostables, how many containers in here are non-compostable?

And this is the bin for general trash, how many containers here should be in the compostables bin?
