Brenntag - The Glocal® Distributor
The players
Tier 1 supplier to Auto Industry supplier
&
Brenntag Great Lakes
High capacity paint lines requiring multiple cleaning cycles
Generating 40-50 drums/month
Solvent is used one time to flush paint lines then disposed
of
High chemical cost for the virgin solvents

The Issues
Can the solvent be recycled?
Solvent specifications of the solvent
Waste solvent must be such that solvent distillation is
economically feasible- Yield ?
Virgin solvent value must be in excess of transportation
and recovery costs
Returned/Reclaimed solvent must meet predetermined
specifications

Specifics of waste
Solvents used to clean paint lines
Waste solvents are RCRA regulated solvents and must
be managed as hazardous waste

Reclaiming results
Lab results show potential recovery rates of 80-90 %
Net result : 22,400 gallons of recovered solvent .
This represents 22,400 gallons of an otherwise waste
material turned into a resource !
Our chemical distribution & blending and analytical
capabilities allow us to perform lab analysis on the
reclaimed material and blend to specification.
