 Overview:

The L2C game helps players understand the steps required to begin a zero-waste program. Players are presented with a “treasure box” that’s meant to represent a firm’s wastes.

Steps

1. Sort the materials.
1. Things you might find:
1. Glass (in the form of flattened marbles)
2. Various types of plastic (represented by clear pink stones and 2×2, 2×4, & 2×6 plastic bricks)
3. Paper/Cardboard (in the form of cardboard rectangles)
4. Aluminum cans (in the form of aluminum buttons)
5. Food waste (in the form of erasers labeled as food)
2. Take an inventory.
1. Notes:
1. Landfill Waste does not appear in your box. Assume it was 25% of the total (so the objects you’re quantifying represent 75% of the total).
2. The different sizes of plastic bricks represent different types of plastic. Use this key to properly account for the material.
1. Plastic Brick counts
1. 2×2 = 60 kg of PET (Polyethylene terephthalate
2. 2×4 = 35 kg of  Low density polyethylene (LDPE)
3. LDPE
4. 2×6 = 100 kg of  High density polyethylene (HDPE)
3. Calculate quantities.
4. Estimate monthly amounts of each material based on the calculated quantities and the number of days’ worth of waste in your “treasure box.”
1. This represents 7 days of waste material.
2. To calculate an average month, divide the total by 7 and then multiply it by 30.42 (365 days / 12 months   30.42 days)
