PROJECT: ENVIRONMENTAL TECHNOLOGY VERIFICATION (ETV) OF BIOSOLIDS PRODUCT
LOCATION: Vancouver, B.C.
DESCRIPTION: A biorecovery facility was seeking to use its product as animal feed supplement. The facility treats biodegradable wastes using an Autothermal Thermophilic Aerobic digestion (ATAD) process. The ETV verification program involved developing a sampling protocol followed by a sampling program that included extensive analytical testing plus solids screening (sieve analysis), identification and classification into seven categories of
distinguishable materials in samples.
 ROLE: Sampling protocol development and sampling.
