Now – more than ever – managing food waste is a big deal.

People all over the globe are concerned about the environment. While there's no single solution for managing and getting rid of the world’s waste, even the simple things we do may have an important impact on the environment – like using an InSinkErator? garbage disposal to keep food waste out of landfills. That may help reduce methane emissions by decomposing food waste. Rotting food also contributes to leachate, an acidic liquid residue that can seep into and contaminate ground water.

Food waste put down disposals may become renewable energy.

In many communities, the food waste sent down garbage disposals flows to a municipal wastewater treatment plant, where it can be processed along with other organic solids. When that happens, methane gas, known as biogas, is produced. Capable treatment plants can capture the biogas and use it to power the facility, saving on operating costs. Then, once the wastewater treatment process is completed at such plants, residual biosolids can be turned into fertilizer or soil conditioner for use in agriculture and home gardening.

Proper operation better protects your disposal & the environment.

It’s best to not grind large amounts of food waste at one time. Rather, slowly put scraps into the disposal and allow it to grind the waste completely before turning it off. That helps it break waste into smaller particles, which are more easily handled by waste treatment systems. Always use cold water and make sure to let the water run for several seconds after grinding is done to flush waste. Never pour oils or grease down the disposal, which could cause clogs in pipes and sewer lines.

Did you know garbage disposals are an environmentally responsible option for keeping food waste out of landfills?

Is it true that disposals put a strain on municipal pipes & sewage systems?

How can using a garbage disposal be environmentally beneficial?

Using a disposal to keep food waste out of landfills can have environmental benefits, from reducing the exhaust emissions of garbage trucks hauling food waste to the decomposing food scraps generating methane and liquid leachate at the landfill.??

Alternatively, a capable wastewater treatment facility can convert food waste from garbage disposals into renewable energy and?fertilizer.

Is it true that disposals put a strain on municipal pipes & sewage systems?

What are biogas and biosolids?

Biogas provides a renewable energy alternative to fossil fuels. When treating wastewater, methane gas is produced. A capable wastewater facility can capture the biogas and use it to power the plant.?

Biosolids are the nutrient-rich organic materials that result from the treatment of wastewater. Biosolids contain many essential plant nutrients and can be recycled as fertilizer or soil conditioner for use in agriculture.


Is it true that disposals put a strain on municipal pipes & sewage systems?

Do garbage disposals use a lot of water and energy?

A garbage disposal uses less than 1% of a household’s total water consumption (less than a gallon per person) and on average costs less than 50¢ a year in electricity to operate (3-4 KWh annually). In a foodservice operation, an average disposal costs about 12¢ per day to operate.?

Additionally, durable and long-lasting InSinkErator? disposals require little, if any, maintenance.

Is it true that disposals put a strain on municipal pipes & sewage systems?

Is it true that disposals put a strain on municipal pipes and sewage systems?

According to more than two dozen independent studies from around the world, garbage disposals do not harm municipal sewer systems. In the United States, installing a disposer also contributes one point towards achieving the NAHB National Green Building Standard.

Research shows garbage disposal use may benefit the environment.

Food waste can be a large contributor to issues related to solid waste management. Studies have shown that when households use garbage disposals to dispose of food scraps, the overall volume of waste taken to landfills may decrease, lessening the environmental impact of food-related waste.?
