Using the data in Table given below, estimate the ‘as discarded’ density of 1000kg of typical residential waste.
| Component | Percent by mass |
| Food Waste | 15 |
| Paper | 45 |
| Cardboard | 15 |
| Plastics | 10 |
| Wood | 5 |
| Tin Cans | 10 |
To estimate the 'as discarded' density of 1000 kg of typical residential waste, we'll first need to calculate the individual densities of the components in the waste, and then combine them based on their mass percentages. The 'as discarded' density refers to the density of the waste after it has been discarded, which means it includes all the components mixed together.
Density is typically measured in units of mass per unit volume, such as kilograms per cubic meter (kg/m³). Here's how we can estimate the 'as discarded' density:
1. Calculate the density of each component:
- Food Waste: The density of food waste can vary depending on its moisture content, but for typical food waste, we can assume a density of approximately 600 kg/m³.
- Paper: The density of paper ___ _______ __________ ___ _______.
