Waste Reduction
Waste is any material that is discarded or thrown away. The impact of waste on the environment is significant. Landfills, where most waste goes, create a variety of environmental problems, including:
When waste is not disposed of properly, it can end up in oceans and other waterways, where it harms marine life and ecosystems. In addition, producing new products from raw materials requires energy and creates pollution. By reducing waste, we can help to minimize these negative impacts.
One way to measure the environmental impact of waste is through a life cycle analysis (LCA). An LCA looks at the entire life cycle of a product, from raw material extraction to disposal. This analysis takes into account the energy and resources used at each stage of the product's life, as well as the environmental impacts associated with each stage. By conducting an LCA, we can identify areas where waste reduction efforts can be most effective.
For example, consider the environmental impacts associated with producing a plastic water bottle. The production process requires the extraction and refining of petroleum, which releases greenhouse gases and other pollutants. The bottle is then transported to a bottling facility, which requires additional energy and resources. Finally, the bottle is transported to stores, where it is sold and eventually discarded. When the bottle is thrown away, it can take hundreds of years to decompose in a landfill. By reducing our use of plastic water bottles, we can reduce the amount of waste that goes to landfills and the environmental impacts associated with producing and disposing of them.
