Hi,

Like the concept of getting energy from waste stuff, renewable or recyclable things. Got some extra cash from a summer job and looking at some of these companies. I'm thinking it might be a good time to start building a position in some of these. Is there a chart or something to compare these companies? Has anyone built a list of these companies? I'm trying to find them by hit or miss in searching. Hoping someone can trim the list down to a few good potentials to save some time. Interested in bio and trash companies but open to other suggestions. Thanks.
