Reduction in Hazardous Waste
Historically, the Amnicola site disposed of
approximately 200,000 pounds of reclaimed styrene
every year.
Created an onsite recycling program to reclaim
styrene previously disposed as hazardous waste.

Reduction in Hazardous Waste
Found a buyer to use the styrene as a raw
material in another manufacturing process.
Results:
Reduced disposal costs
Reduced regulatory fees
The facility’s hazardous waste generator
status was reduced from a Large Quantity
Generator to a Conditionally Exempt Small
Quantity Generator.
