In , Table 1 shows energy requirements for Materials, Production, Use, Disposal of a washing machine normalized to a single wash load. The results are summarized here:
Category | MJ/wash load |
Materials | 1.5 |
Production | 0.2 |
Use (heating water, agitation, electronics, energy embodied energy of water) |
7.0 |
Disposal | -0.4 |
Total | 8.3 |
Here the negative value for Disposal represents recovered energy from material recycling and waste-water treatment.
The article also describes the ill-effects of miscounting resources when combining life-cycle analyses (LCAs) for multiple products with incongruous boundaries . They call this the "washing machine effect".
