How to Create a Lean Manufacturing Process with Environmentally Friendly...

Running the Numbers:



So, how do the numbers wash out Here is a way to conduct a preliminary feasibility study to begin your return on investment justification. This five-minute analysis could save you millions in cost savings.



Conducting an instant preliminary feasibility study:



Undoubtedly, you have some questions. You are wondering whether self-cleaning filters can help with your waste minimization problems. Or just how much they can reduce your disposal costs. Or improve your return on investment.



Grab a calculator and a pencil. By completing the following self-survey, you can quickly calculate what disposable media filters are costing you in terms of disposal costs alone.



When you finish, you will have taken a major step toward determining whether self-cleaning filters are a viable alternative to the filters you are currently using or considering.



Determining Your Disposal Costs for Disposable Media Filters:



1. For one filter, multiply the number of cartridges or bags it contains by the number of changeouts per year. This will give you the total number of spent media per year. Write your answer below.



Example: A cartridge filter with 36 - 10-inch cartridges is changed every week: 36 cartridges x 52 weeks - 1,872 cartridges per year.



CARTRIDGES PER YEAR: __________



Spent Media per Year:



2. If you are using 10-inch cartridges or bags, divide the total number of spent media per year by 180 (this is how many of these cartridges or bags fit into one 55-gallon drum). If you are using 30-inch cartridges, divide the total number of spent cartridges per year by 60. In each case, the result is the total number of 55-gallon drums that you will fill each year.



Example: 1,872 total spent cartridges divided by 180 = 10.4 barrels per year.



BARRELS PER YEAR: __________



10-inch cartridges or bags:



30-inch cartridges:



3. Multiply the number of barrels per year by the cost per barrel for disposal.



Example: Assuming you pay $500 per barrel for non-hazardous waste (or $1,000 per barrel for hazardous waste), the calculation is 10.4 x $500 = $5,200 (or 10.4 x $1,000 = $10,400).



DISPOSAL COSTS PER FILTER PER YEAR:



Remember 's8211; these calculations are based on a single filter, and they account for disposal costs only. Additional costs include the purchase price for disposable cartridges or bags (typically at least $3 apiece) as well as associated costs such as the labor required for media replacement, the increased emissions, and the increased safety risk.
