Measure Baseline Costs
Input solvent $3.50/gallon × 4,000 = $14,000 per
yearWaste disposal
$2.50/gallon × 3,950 = $9,875 per year

Identify Options
1. Recycle solvent2. Use non-hazardous cleaning
method

Measure Waste Generation for Option 1
New solvent
RECYCLE
Fugitive emissions
CLEANING PROCESS
360 gallons
3,950 gallons
50 gallons
Waste disposal
3,640 gallons
310 gallons

Measure Benefits Option 1
No change in production of output, so no revenue change for output
No revenue from recycled solvent because it is used rather than sold.

Outcome?
Comparing recycling to current practice, would save $81,317.23 over 10 years
Comparing material substitution to current practice, would save $75,702.02 over 10 years

What is Life Cycle Analysis?A tool to understand environmental impacts
associated with products, processes, and activitiesLCA is a systems approach to evaluating
environmental consequences of a product or process
It takes a “cradle to grave” or “cradle to cradle” perspective.
A systematic set of procedures for examining the environmental impacts of a product or service throughout its life cycle

Applications
Alternative Fuels/energy sourcesAlternative materials (Aluminum vs. Steel body,
Asphalt vs. concrete, wood vs. brick
Alternative processes (Corn-biomass ethanol)
Alternative products (cloth diapers vs. disposable diapers)
Alternative packaging (cans vs. tetra-packs)Alternative end of life management options
(recycle, incinerate, dispose)Environmental, economic tradeoffs
