So what I do is to have a large compost pile, with an open space next to it. I want to turn that compost at least once a month in the winter, and every two weeks in the spring. Now I don't have enough time to turn the entire pile, so what I do is take my excavator and start moving compost from one pile to a new pile, eventually making it look like it's a trench. I'll spend an hour or two every day moving a small bit of the compost, eventually ending up with one big pile again.

Municipal composting facilities deal with this problem by just grinding the compost up so that the plastic is in small enough bits that people don't notice it. I don't like that solution because those little bits of compost don't really ever break down, and I know animals will eat it. I'd rather keep the plastic out of the compost entirely, but given our societies love affair with plastic food packaging I know that this will be an ongoing (and never ending) process.
This particular compost pile is almost done. I'll be growing my household vegetables in it this year.
