I've had to build fire & gas detection systems for ~15 diary farm biogas operations in the last two years. It isn't even in our usual list of clients to work with, we just happened to have an oilfield client pass our name around and got calls for these systems a year or two later.

If our tiny company is getting requested to bid on life safety systems for biogas operations it must be a lot bigger of an industry than you believe it to be.
