1. SUBJECT: Coolant Recycling System
REQUEST #:
FUNDS: $XX,XXX
Strategy
EXECUTIVE SUMMARY:
Capital funds in the amount of $XX,XXX.XX are required in order to purchase, fabricate, and install a
coolant recycling system. The current management process for coolant maintenance is to use it to end of
life cycle, then dispose of it after processing through the evaporator. Annual average cost of new coolant
purchases over last three years is about $XXX,XXX Through the recycling process,we will see a minimum
10% reduction within the first year of implementation ($XX,XXX). This percentage will improve as the
program matures.
TECHNICAL DESCRIPTION:
The system will hold up to XXXX gallons of coolant. There are three holding tanks where contaminants are
continuously removed from the coolant. System will require an air supply and standard electrical connection.
There is a single control panel that measures coolant level controls the transfer and processing of coolant.
JUSTIFICATION:
Current coolant management practices result in high product cost and machine downtime due to servicing
coolant sumps for draining and recharge of necessary metal working fluids. By withdrawing coolant from
machines before it reaches the point of expiration, it can be reformulated and reused rather than disposed of. As
the program evolves, the goal will be an annual reduction of new coolant purchases of approximately XX%.
Additionally, used coolant/oil is a leading contributor to our Industrial process waste stream. This initiative
supports environmental metric goal reductions for 20XX goals of recycled and non-recycled waste.
Furthermore, it establishes a foundation to address recycling opportunities toward the 20XX Environmental
goals. Directly affected metrics include Green House Gas by reducing natural gas burner use at the evaporator
(XXKccf and $XXXXX), purchased city water will reduce by XXXKgals, used coolant disposal and
transportation will be reduced by XXXKlbs, and $XXXXX in transportation costs. Total expected savings in
year 1 of the initiative is $XXXXX dollars. This figure does not include oil services labor or down/service time
on the production machines involved.
ALTERNATIVES:
Various companies were solicited for alternative solutions. EH&S staff and Site benchmarked
manufacturing facilities in Connecticut utilizing different models of coolant recycling systems. One of the
sites was the coolant management team selected as a finalist for the leadership awards in 20XX. (A copy of
the leadership package can be supplied upon request). Based on the number of machines in the facility,
floor space available, and volume of coolant that will be processed,this technology and eventual
management strategy was selected. EHS research supports that recycling systems can reduce coolant
purchases by the aforementioned minimum XX% to XX%, with growth potential to XX%. Associated
disposal costs and volumes are also expected to be at least XX%. Simple system payback is anticipated to
be XX months or slightly less, (when factoring in labor and down/service time) depending on energy and
waste transportation costs.

2. RISK & OPPORTUNITIES:
There are no risks associated with this investment only the opportunity for improvement; such as a cleaner
more effective work environment and the continued support toward the reduction of environment, health and
safety hazards in the workplace. The list below identifies additional opportunities:
Improvement on productivity, tool life, and part
finish
Superior coolant condition & reduced odor complaints
Overall cleanliness of coolant part of machines Reduced disposal/shipping liability associated
with waste product
Green initiative with lower water consumption Cleaner less pungent odors from evaporator
Positive culture change among operators Less downtime for machines during coolant change
OPERATIONAL PLAN:
This is an out of plan request for Capital. Capital approval is expected in December 20XX, followed by a
purchase order. Receipt of equipment and install will be completed in March, and system will become
operational in April, with Capital Closure in July 20XX.
