Recently, the Environmental Science II class received a mechanical mixer through a generous donation from Dave Harris of Erie. This mechanical mixer will aid in the planned anaerobic decomposition of the High School's protein waste. What this means is that from now on, EJSHS will not throw away any food waste!!
This is very exciting as it adds an additional dimension to our goal of solid waste reduction in the district. The machine will mix the food waste with various sources of nitrogen (manure, grass) and carbon (paper). This mixture will in turn be spread into windrows to process.
The windrows will be monitored to make sure high temperatures are present for sufficient breakdown of the protein material. At the end of the process period (approx. 90 days), we will have a large amount of high-nutrient fertilizer!
This fertilizer is going to be bagged up in used feed bags, and thanks to Ranch Aid Inc., sewn shut for distribution!
Go Green Team!
