Does anyone know about the relative trade-offs of composting and recycling? Many of the trendier environmentally-aware people I see around me seem to prefer composting, including compostable disposable cups, etc.<p>But it&#x27;s not clear to me that composting would be better. What is the chemical composition of this compost of somewhat random materials? Is it safe? Is there waste? Is it usable as quality compost? Does it get used? How much demand is there? etc.
