Waste

As populations and resource demands climb, waste production contributes to emissions of carbon dioxide, leaching of hazardous materials into the soil and waterways, and methane emissions. In America alone, over the course of a decade, 500 trillion pounds of American resources will have been transformed into nonproductive wastes and gases. Thus, a crucial component of sustainable living is being waste conscious. One can do this by reducing waste, reusing commodities, and recycling.

There are a number of ways to reduce waste in sustainable living. Two methods to reduce paper waste are canceling junk mail like credit card and insurance offers and direct mail marketing and changing monthly paper statements to paperless emails. Junk mail alone accounted for 1.72 million tons of landfill waste in 2009. Another method to reduce waste is to buy in bulk, reducing packaging materials. Preventing food waste can limit the amount of organic waste sent to landfills producing the powerful greenhouse gas methane. Another example of waste reduction involves being cognizant of purchasing excessive amounts when buying materials with limited use like cans of paint. Non-hazardous or less hazardous alternatives can also limit the toxicity of waste.

By reusing materials, one lives more sustainably by not contributing to the addition of waste to landfills. Reusing saves natural resources by decreasing the necessity of raw material extraction. For example, reusable bags can reduce the amount of waste created by grocery shopping eliminating the need to create and ship plastic bags and the need to manage their disposal and recycling or polluting effects.

Recycling, a process that breaks down used items into raw materials to make new materials, is a particularly useful means of contributing to the renewal of goods. Recycling incorporates three primary processes; collection and processing, manufacturing, and purchasing recycled products. A natural example of recycling involves using food waste as compost to enrich the quality of soil, which can be carried out at home or locally with community composting. An offshoot of recycling, upcycling, strives to convert material into something of similar or greater value in its second life. By integrating measures of reusing, reducing, and recycling one can effectively reduce personal waste and use materials in a more sustainable manner.
