Waste Tires This fact sheet discusses waste tire
handling and disposal for businesses.
Parts
Washing When choosing a parts cleaning system, shops
need to evaluate both the cleaner and the parts washing
equipment. Often cleaners and the wastes produced during
parts cleaning pose exposure risks to the users, and
in most instances, wastes produced during the parts
cleaning process must be managed as hazardous.
Waste
Tire Disposal Tire disposal in Minnesota is regulated
for many reasons, including concern for public health,
the potential for fire hazards and the expense of cleaning
up after tire fires. This fact sheet outlines ways for
your business to properly manage waste tires.

of wood finishing operations. In 1994, Automated Building
Components of Chanhassen, Minnesota, began to explore
non-hazardous alternatives to standard coatings that
ultimately led to successful conversion to waterbased
finishes.
Trichloroethylene
Examining
Root Causes at X-Cel Optical With the help of a
MnTAP intern, X-Cel Optical eliminated use of trichloroethylene,
reducing the grinding department's cycle time from three
days to two hours. Operating costs for grinding glass
buttons was reduced by two percent.
Petroleum
Solvents and Production Changes Replace Chlorinated
Cleaning Solvents
To eliminate 1,1,1-trichloroethane and CFC-113, Windings,
Inc. converted two vapor degreasers to cold solvent
dip tanks, constructed two stands for drying parts and
changed operating procedures to eliminate the final
stator cleaning step on 85 percent of the units it made.
Note: Although production of both 1,1,1-trichloroethane
and CFC-113 was banned in 1995, these process changes
apply to other chlorinated solvents like trichloroethylene
(TCE), methylene chloride and perchloroethylene (perc).
