Attachment 15: Sample Weights of Common <strong>Lunch</strong> Items<br />

If your bathroom scale <strong>is</strong> not sensitive enough, try weighing yourself with <strong>the</strong> container filled with <strong>the</strong> waste you<br />

are attempting to measure. Next, weigh <strong>the</strong> container and yourself. Subtract your first number from <strong>the</strong><br />

second— th<strong>is</strong> <strong>is</strong> <strong>the</strong> weight of <strong>the</strong> material. (See page 43 for a sample calculation). If you have very little waste,<br />

a regular scale may not be sensitive enough to calculate <strong>the</strong> waste produced. Th<strong>is</strong> guide provides typical<br />

weights for items found in a lunch.<br />
