10.01 Solid Waste Ciara Goins May 2, 2019 Lydia Goodrum Objective(s): The objective of this lab is to collect and analyze personal garbage content, compare personal garbage analysis to national averages, propose methods to reduce solid waste production, and compare recycling amounts to total solid waste production. Procedure: Using a plastic garbage bag(s), collect all of your family’s garbage for a two-day period. Do not throw “dirty” garbage in your bag (i.e., when you use toilet tissue, just estimate the number of squares you used and record it.). 1. After a two-day period, separate your garbage into the categories listed on the data table. Wear plastic or rubber gloves if you wish. A good way to separate garbage is to spread newspaper or paper towels on the floor and sort the garbage into piles. 2. Using either the kitchen scale or the bathroom scale, measure the mass of each of the separated categories. Remember to divide your total mass of each category by 2 to get a one-day average. 3. Count the number of items in each category. 4. Complete the data chart on the following page. When you have competed the chart, you may clean up your garbage. Data: Data Calculations ● Divide each component category subtotal by the total mass of garbage produced to get the mass percent for each category. Example: (mass glass/total mass) × 100 = mass percent for glass ● If you do recycle or compost, divide the amount by the total amount produced to determine how much you are saving.
