Garbage Disposal Impact On Daily LifeJuly 3, 2018
Let’s take a look why should we use the garbage disposal in your homeland. Many people said that: “of course, because it is a convenience for me” or “that is effortless food waste resolution, it saves more time for other jobs or just make things cleaner and easier with the food waste.
They are totally right. Actually, beyond of that, using a 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 the 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 to divert it to alternative recycle resource rather than burying under the solid soil. And garbage disposal is one of a brilliant way to help resolve this problem.
What are garbage disposal impacts to the 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 efficiently 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 a 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 the 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 called Life Cycle of food waste Using disposers. It clearly defines how garbage disposal involves in control polluted greenhouse gas into the environment. In the sample analysis, this research state that if a community of 30000 houses transfers 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. It conducted through anaerobic digestion or turn it into fertilizer product; also known as biosolids, which can help build 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 also has analysis several critical environment impacts: global warming, 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 also concludes that processing of food waste through these advanced waste water treatment facilities has lower energy demand – less than landfill, incineration and centralizing composting.
