However, this use of algae as a means to treat sewage as well as serve as biofuel is noteworthy because it also serves to remediate an environmental liability. I proposed this in an article I published five years ago where I question the use a switchgrass as a sustainable biofuel. I suggested...

About this blog

This blog was originally created in January 2013 to serve as a means for providing updates on science activities from the environmental science lab manual Ecology, Development, and Sustainability. I have now expanded its purpose to include other items of interest to science teachers.
