Why is the tar sands project have so much pollution?



  1. 0 Votes

    The tar sands project demands an extraction and separation process that results in high emissions and pollution. Tar sands are acquired through open pit mining. The sand is then transported to an extraction plant where hot water is used to extract the bitumen (oil product) from the sand. Some sands are too deep to extract so extraction of bitumen happens on site via steam injection, solvent injection, and firefloods. These processes leads to contaminated water and toxic leakage through regular extraction plants, solvent injection, and steam injection. Firefloods, which requires burning of some bitumen to extract more bitumen, results in millions of tons of carbon dioxide being released everyday.
