Clean Harbors, Inc. (NYSE:CLH) is looking for M&A. Michael Battles, Chief Financial Officer said, "When I think about kind of M&A opportunities and kind of where we deploy capital, kind of we love all children equally. And we think that it's all about kind of where we get the best return. That could be through M&A, that could be through capital spend, we're building a new incinerator in Western Nebraska.

And so I feel like it's kind of ROIC-driven decisions, and I think that's been paying off. I see plenty of opportunity certainly on the small side over the next year or 2 in that area".
