At Woodland Park Zoo we have been composting our animal waste for more
than 25 years. We are always looking to improve our process and product
so we would like to know of other institutions that compost their
animal waste. Specifically we would like to know if you test for
contaminants and, if so, what do you test for? Any information will be
greatly appreciated.
