Table 2 Measured dry and wet weights of coffee pods. *These are the wet weights referenced within the projected scenario results. Wet weights reflect the model closest to the one that facilities services have to consider in terms of disposal.
From: Life Cycle Assessment of Compostable Coffee Pods: A US University Based Case Study
Product | Empty dry weight of coffee pod | Dry weight | Wet weight* | Difference (water content) |
|---|---|---|---|---|
Plastic coffee pod #1 | 3.0213 g Difference between empty cup to dry weight => Amount of coffee = 8.9787 g = 9.9787 g = 4.9787 g Average coffee weight: = 23.9361/3 = 7.97 g => 8 g | 12 g | 21 g | 9 g |
Plastic coffee pod #2 | 13 g | 19 g | 6 g | |
Plastic coffee pod #3 | 8 g | 18 g | 10 g | |
Average dry weight of plastic pods: Â 11 g | Average wet weight of plastic pods: Â 19.3 g | Average water weight: 8 g | ||
Compostable coffee pod | 3.0622 g Difference between empty cup to dry weight => Amount of coffee = 11.9378 g = 10.9378 g = 10.9378 g Average coffee weight = 33.8134/2 = 11.27 g => 11 g | 15 g 14 g 14 g | 24 g 3 g 24 g | 9 g 9 g 9g |
Average dry weight of compostable pods: Â 14.3 g | Average wet weight of compostable pods: 23.6 g | Average water weight: 9 g |
