Introduction to and Operating Instructions for 457.xls1. 457.xls is a spreadsheet intented as a companion to "Integrated Solid Waste Management" Tchobanoglous, Theisen and Vigil, McGraw-Hill 1993, ISBN 0-07-063237-52. The problem or example reference (tab at bottom of page) is also the spreadsheet title e.g. spreadsheet Pr3-4 refers to problem 3-4 on p.67 of the referenced text3. The user is encouraged to make a copy of the original disk and use the copied disk as a working tool.4. When working with a particular sheet, is recommended that the Edit>Move or Copy Sheet menu be exercised to create a copy of the sheet of interest. Check on "Create a copy".
EDIT THIS COLUMN or EDIT THIS FIELD is often included. 6. The sheets may be unlocked with Tools>Protection>Unprotect Sheet; the sheets may be locked with Tools>Protection>Protect Sheet7. Many styles of graphs have been included as a demonstration.8. The sheets may be used in a variety of ways including Tools> Goal Seek which can adjust a chosen cell to meet a desired target.
5. The sheets have been "locked". Generally only the columns that are bolded can be edited or changed. The comment

Assumptions and Comments:1. The landfill life is 5 years which is unrealistically short, nonetheless, the enclose calculations provide a starting point for a longer analysis. All calculations are based on 1 pound of waste.2. For RBW and SBW, the gas production and rate of gas production is modelled by a triangle whose ordinate, y, value is the gas production rate, ft3/yr, and whose abscissa, x, value is the time in years. In other words, the rate at any time is the corresponding rate, y value, associated with that time. The area under the curve is the gas production, ft3. The gas production between the end of year 3 and the end of year 4 is the area under the curve for those time periods which in this case is a trapezoid whose base is 1 year (4-3) and whose bases are the rates at years 3 and 4. Area trapezoid=.5h(b1+b2).3. For RBW, the time period for activity is 5 years and the peak is achieved at the end of the first year leaving 4 years after the peak. From the peak, the rate slopes to 0 at the end of the 4th year which is the beginning of the 5th year. The peak is, therefore, PEAK*4/4, the rate at the end of year 2 is PEAK*3/4; year 3=PEAK*2/4; year 4=1/4; year 5 is 0. The total area under the curve is 14ft3. 4.For SBW, the time period for activity is 15 years and the peak is achieved at the end of year 5 leaving 10 years after the peak. From the peak, the rate slopes to 0 at the end of the 15th year which is the beginning of the 16th year. The peak is, therefore, PEAK*10/10, the rate at the end of year 6 is PEAK*9/10; year 7=PEAK*8/10; year 8=7/10 etc.; year 15 is 0. The total area under the curve is 16ft3.
