Waste Stream Overview:
Estimate how much of your waste falls
into these common categories, adding
more categories if necessary.
|___% Engine Fluid
|___% Surplus Parts/Miscellaneous
First, consider alternatives for using less harmful products such
as recycled mechanical fluids. Then use
this checklist to identify possible problem areas and develop your pollution
Engine Fluid Waste
All engine fluids - Do You?
- Practice proper storage and spill prevention techniques as described
in - General Housekeeping.
Oil - Do You?
- Use or donate used oil to be burned in a waste oil heater (heat your
shop or greenhouse)
- Use a reputable recycling service or collection program to collect
- Prevent oil from being contaminated (and thus becoming hazardous waste)
through contact with other wastes.
Antifreeze- Do You?
- Properly label used antifreeze
in a spill proof container. (Ideally, put it back into its own container,
but remember to label accordingly.)
- Consider an antifreeze recycling
- Seek a partnership with a
local shop in town to share a recycling unit
- Keep antifreeze segregated
from other waste
- Seek a partnership with a
local garage or government facility to turn over antifreeze for recycling
Transmission fluid - Do You?
- Handle transmission fluid
and other heavy oils like regular motor oil.
- Consult the heater's manufacturer
before burning it in a waste oil heater.
- Consult your recycler to see
if these fluids may be integrated with standard motor oil.
Brake fluid - Do You?
- Avoid contamination with break
- Store in their own segregated
- Investigate local recycling
or collection options.
Parts cleaning solvents -
(Solvents can be expensive; conservation can lower your costs.)
- Consider less hazardous strippers
- Reuse solvents when possible.
- Pre-clean with dry methods
to remove excess dirt and grease whenever possible.
- Filter solvents to prolong
- Avoid F-listed (chlorinated
- Use proper storage and spill
containment techniques described under General Housekeeping
- When you must dispose
of solvents, be sure to: use a legitimate recycling facility,
OR a permitted hazardous waste treatment facility.
Spill protection while changing
fluids - Do You?
- Install drip pans and trays
throughout the shop — under vehicles and wherever liquids are transferred.
Tires - Do
- Avoid acquiring junk tires
at all cost!
- Try to set up a recycling
connection for tires through a local tire store, recycling service,
garage or government facility.
- Realize it is illegal to burn
tires. (It is usually legal to dispose of tires with approval of the
landfill, but most landfills charge a fee.)
- Do You?
- Drain filters into used oil
- Recycle filter bodies.
- Practice spill prevention
procedures while draining.
- Avoid using terne-plated filters
which are difficult to properly manage.
batteries - Do You?
- Store used batteries off the
ground, upright in a secure covered location to prevent leaks and temperature
- Recycle batteries through
a local recycling service, garage or government facility.
- Remember not to stack batteries.
- If you drop a battery, neutralize
the spill with baking soda or lime.
- Wear proper personal safety
clothing when handling batteries.
and towels - Do You?
- Avoid disposable shop rags,
utilize a shop towel laundering service.
- Wring out shop towels (into
an appropriate waste container) to reclaim solvents and other products
(use proper personal protection, e.g. gloves).
- Avoid chemicals which may
hinder laundering of shop towels (e.g. perchloroethylene and toluene).
- Keep clean and dirty shop
towels in separate, well-labeled containers.
- Do You?
- Know that absorbent materials
(sawdust, kitty litter, etc.) containing absorbed materials may be considered
hazardous and will require special disposal.
- Use drip trays and pans to
- Use squeegees to recover product
and cleanup spills.
- Consider using rags that can
be “wrung” out to recover product.
Containers and Packaging - Do You?
- Reuse empty clean containers
for storage of appropriate items.
- Return empty containers to
the distributor for reuse where possible.
- Use empty containers for storage
of fluids to be recycled
- Store fluids in properly labeled
containers and never mix e fluids inappropriately.
- Reuse and recycle paper and cardboard
as recommended under General Housekeeping.
- Buy products with as little
packaging as possible
- Separate reusable and recyclable
packaging materials from those that can only be disposed of.
Parts, Miscellaneous, and Metal Waste - Do You?
- Use parts for other projects or repairs; or turn in for salvage value
- Recycle metals with other metal
waste (may require separation of different metals).
- Sort usable or recyclable pieces
from unusable mixed solid waste
- Observe proper disposal rules for
the remaining (unrecyclable) portion.
Adhere to all WATER QUALITY, AIR QUALITY and ENERGY CONSERVATION recommendations
listed in General Housekeeping.
