Vermiculture produces EQ class A biosolids at wastewater plant

Article Abstract:

A central Pennsylvania facility has become the first in the United States to receive a permit to make and use biosolids from a process-controlled vermiculture system. Vemitech, an Australian company utilizes earthworms housed in large, industrialized, continuous-flow reactors to process and transform the township's biosolids into an attractive, odor-free material known as vermicompost.
