Garbage disposal, Why should we use it?

Why should we use a garbage disposal?

Why should we use a garbage disposalLet’s take a look why should we use the garbage disposal in your home land. Many people said that: “of course, because it is convenience for me” or “that is effortless food waste resolution, it save more time for other jobs or just make things more clean and easier with the food waste.

They are totally right. Actually, beyond of that, using garbage disposal in your kitchen also help protect your environment as well.

Imagine that there is no garbage disposal in your homeland. There are tons of daily food wastes and where should they go? The landfill is the major answer.

According to EPA, the landfill is the major source of methane, greenhouse gas that is potent nearly 21 times of carbon dioxide. And your guest is right. The major component of landfill that produces most of this gas is food waste.

Because food waste is major component to make this problem worth, many cities’ goal is divert it to alternative recycle resource rather than burying under the solid soil. And garbage disposal is one of brilliant way to help resolve this problem.

What are garbage disposal impacts to environment?

Using this garbage disposal can cause significant problems if the waste water is not ready for it. The first important thing that is garbage disposal need more water. You typical using more water to help grind up food waste more efficient and keep the unit more longevity. The more you grind the more taking use of water. This can be critical problems if your community is dry or have to save water for agriculture.

If lack of water is not your problem, then there is concern of the contaminant water will change the chemical composition of natural water? It will strongly affect the aquatic life like algae blooms, which is considerate as contaminated water. However, most of waste water treatment system is design good enough to handle this problem. This only happens as long as the local waste water treatment is not ready for it. In this case, they will refer landfill treatment which is easier to execute.

Which is best for environmental protection, landfill or waste water treatment?

Which have shown above is call Life Cycle of food waste Using disposers, which clearly define how garbage disposal involve in control polluted greenhouse gas into environment. In the sample analysis, this research state that if a community of 30000 houses transfer all of their food waste into garbage disposal instead of sending to landfill will reduce up to 2,100 tons of carbon dioxide emissions. That is about 4.6 million miles of car traffic.

Moreover, many advanced waste water treatment plants can convert the food waste from garbage disposal into renewable energy through anaerobic digestion or turn it into fertilizer product, also known as biosolids, which can help build a healthy soil.

The above result of the Life Cycle Food Waste is based on the assessment of environmental impacts of  four primary system of managing food waste – waste water treatment, landfill, incineration and advanced composting. This report has also analysis several critical environment impacts: global warning, acidification potential, smog formation, the energy demand associated with each system and so on.

In summary, this report state that food waste processed through waste water treatment plant with anaerobic digestion and co-generation can even result in a reduction of global warning potential. It’s also conclude that processing of food waste through these advanced waste water treatment facilities has lower energy demand – less than landfill, incineration and centralizing composting.
