Biosolids – What your community needs to know and will never want to forget

The value of biosolids treatment, processing, and land application for all Pennsylvanians is something of a lesser known fact, yet one that becomes increasingly important when they are considering increases in water and sewer bills or considering higher prices for their local produce, or even more so for those more rural Pennsylvanian communities whose chief industries include agriculture and agriculture related industries.

This webinar will cover the history of biosolids in the United States and Pennsylvania, as well as the importance of biosolids to every Pennsylvanian.  Practitioners in biosolids will be identified and clearly defined, including public agencies who treat wastewater, the engineers and other organizations they work with to do so, and the farmers who use them on their land, as well as the state and federal regulators who oversee the process. In addition, the webinar will cover the latest technologies and trends for the future, including fertilizer pellets, compost, nutrient recovery and renewable energy options.
