Switching from land application to biofuel generation reduces our reliance on petroleum products. That's a big plus.

Land application of sewage-derived biosolids is harmful to the environment and to human health. In addition to the viable pathogens, there are many other harmful compounds contained in our sewage plant waste, including heavy metals and many other toxic compounds. The practice of land-applying this waste as fertilizer for grasses that are consumed by cattle, ultimately bound for human consumption as milk and meat, is a dangerous practice. The fact that this is allowed by the current regulatory regime, is cold comfort to those who know better.
