Tissue Digestor™ - Cost Calculator

What this calculator does:

The form below will calculate an estimate for the cost of operating a WR² Tissue Digestor™ when you enter your local costs for electricity, water, sewer, etc.
The calculator estimates costs only for models operating at 300°F and is based on typical loads, typical cycles, and use of potassium hydroxide solution.

What this calculator does not do:

This calculator does not estimate cost of operation for low temperature models, Effluent Decontamination Systems, or the STI Medical Waste System.
This calculator does not estimate costs for using alternate alkali.
Tissue Digestor automatic cycles may be customized for atypical waste loads, using more or less water, alkali and longer or shorter cycle times. This calculator will estimate costs only for typical cycles and loads.
Please contact a sales representative for more information if you need more information.

Enter values of variables to use for the calculation

What is the maximum capacity required? (Enter the largest load you expect to run in lbs.)	lbs
What will be the average load run? (in lbs)	lbs
What is the cost of water per gallon? (in $/gal)	$ /gal	Cooling water may be captured for reuse in the next cycle (requires additional equipment). Grey water may be used for all aspects of the process.
Estimated Alkali cost per pound. ($/lb) (Formula assumes alkali used is KOH 45/55% solution.)	$ /lb	Technical grade KOH 45/55% solution cost varies depending on quantity bought at once. One vendor listed price variation from $0.0725/lb to$0.30/lb.
Electricity cost per KWH (in $/KWH)	$ /KWH
Steam cost per pound of 70 psi steam. ($/lb)	$ /lb
Sewer cost ($/gal)	$ /gal
Landfill cost ($/ton)	$ /ton

Alkali (assumes weight of 45/55% KOH solution needed is 23% of tissue weight)
House Steam (estimated high)
Water Usage (with hot rinse)
Solid waste produced per cycle (bone remnants, moist)
