At all stages, an LCA is likely to include information about the use of energy, transport of materials, and the release of waste substances into the environment.
The manufacture of products has an impact on the environment, including:
The impact of a product on the environment during its use depends on the type of product. For example, a wooden chair has very little impact, unless it needs cleaning or repair. On the other hand, a car will have a significant impact.
The disposal of old products has an impact on the environment, including:
The table shows some data about the energy needed in the life cycle of a pillow case.
|Life cycle stage||Energy use|
Discuss the use of energy during the life cycle of the pillowcase, and describe one way in which the energy use could be significantly reduced.
15% of the energy use is associated with making the pillowcase, and very little in disposing of it. The greatest use of energy happens when it is being used, probably because of washing, drying and ironing the pillowcase. Energy use could be reduced by drying it outside and without ironing it.
