Waste management is a crucial part of any community’s overall environmental health. The way we produce, store, and dispose of waste has a direct impact on our water quality and biodiversity. While there are many different methods of managing waste, reducing and recycling are the most sustainable practices. These strategies reduce our reliance on natural resources and help protect the environment.
For example, when it comes to food waste, 30 to 40 percent of the United States’ annual food supply is wasted. This waste is a significant burden on our landfills, which are already filled to capacity. In addition, it is a major contributor to climate change. There are several ways we can prevent food waste, from buying only what we need to using leftovers for future meals. Some of these methods include donating unwanted food, using a reusable container to store it, and using manure as a soil enhancer for plants.
Historically, most industrial, commercial, and household waste has been placed in landfills or surface impoundments. These sites are often leaking and have been found to contain toxic materials that have contaminated groundwater, rivers, and streams. In addition, this waste often releases dangerous gases into the atmosphere and leaves behind ash that can be inhaled by humans and animals.
The primary purpose of waste management is to ensure that the amount and type of solid waste generated is controlled and that it is managed in a safe and responsible manner. This requires an understanding of the various types of waste and their impacts on the human environment, the land, and water resources. It also involves an analysis of the best methods for handling each type of waste.
There are many factors that influence the amount of waste a community generates, including economic activity, consumption habits, and population growth. However, a key factor is public awareness. Currently, public awareness is poor and needs to be improved by integrating environmental education with emphasis on solid waste into school curricula beginning in primary/elementary schools. This could also be done through local radio and newspapers, community events, etc.
One of the best ways to increase public awareness about solid waste issues is to provide training and education for waste managers and other relevant personnel in a community. This includes training in the use of decontamination technologies and a clear understanding of what constitutes a hazardous waste stream.
Another way to improve public awareness is to encourage the 3Rs – reduce, reuse and recycle. Ideally, this process should occur throughout the community from generation to disposal. This method can significantly lower the cost of disposal by reducing the amount of waste and lowering the need for extraction of resources. For example, reusing or recycling plastic bottles reduces the need for new ones to be made. In addition, this process helps to minimize the risk of contamination by reducing the number of waste streams that may need to be transported to a hazardous waste facility.
