Do large waste companies really recycle?

This topic came up during a workshop in Pasadena regarding the open spaces program. Also of interest can there be a 0% to landfill waste program? Can all waste be recycled is probably a better question.

There should be a rating system of sorts, or a qualification system that in order to operate in a city limit the company needs to be approved and offer recycling services. Some level of recycling by the waste pickup company is mandatory.
