Your firstIf 30,000 households in a given community switched to using a garbage disposal, the global warming potential would be reduced by a 1.9 million kg of carbon dioxide when disposing of food waste. And, this isn’t the only benefit of using a garbage disposal. As wastewater treatment facilities continue to install technology that converts food waste to biogas, garbage disposals have the potential to play a big role in actually creating renewable energy. Whereas composting was once seen as a time and cost-efficient method in regards to the natural benefits it offers gardeners, there are many difficulties with this method that can actually be combated by utilizing a good waste disposal system in your home.
Garbage Disposal Units & Sustainability in Biogas
Wastewater treatment facilities are beginning to adopt a technology called anaerobic digestion that can convert all of your discarded banana peels, coffee grounds, egg shells and other food items into biogas, which is a methane-rich byproduct that can be used for energy generation. Whereas it was once thought that using a garbage disposal consumed too much electrical energy and contaminated the local waterways, studies are actually showing that it’s quite the opposite. Waste from garbage disposals is 70 to 90% water, which means that the water generated from garbage disposal waste can actually be used to benefit the local community. By using specialized treatment facilities that are designed with technology that captures the methane gas, it can be cleaned and not only put back into the local water system, but be used as fuel. Choosing to use a garbage disposal in your home, therefore, not only has the potential to help generate biogas fuel for your community, but can also help cut down on costly transportation fees that can pollute the area you live in.
The Difficulties of Composting
In the United States, most food gets sent to the landfill. In fact, 54% of food waste is sent to landfills, according to the U.S. Environmental Agency. When food gets sent to landfills, it decomposes underground, which causes it to produce methane gas, which is 20 times more potent than carbon dioxide. On top of the harmful environmental consequences of composting, the method requires the use of and organics collection system that depends on transportation that is costly and can pollute the environment. These types of collection systems are present in larger cities where the collection of compost can also present issues with the costs of scrap bins and separating food waste.
The Future of Sustainable Waste Disposal
More than 1,200 US wastewater treatment plants have anaerobic digesters producing biogas, with more and more being installed each year. The effort to reduce the number of harmful toxins released into the atmosphere through food waste continues to pick up steam and households around the country are seeing the benefits of turning to a properly installed and maintained garbage disposal unit in order to increase sustainability and reduce their impact on the environment.
