Landfills majorly contribute to global warming, being the largest man-made producers of Methane gas. When food waste is disposed in a landfill, it starts to rot and becomes a major source of methane production.
Isn’t it time we considered recycling food waste into energy? Methane is a greenhouse gas which damages our environment 21 times more than carbon dioxide does. By sending organic waste to landfills, we are harming our environment.
A recent study shows that 34% of the waste that we send to the landfill is organic. Recycling food waste, generally known as composting, is a step we can take in order to benefit the environment by reducing the garbage production which results in the decrease of greenhouse gas emissions.
The environmental benefits of composting in contrast to the alternatives of burning or burying food waste are far more.
Benefits of Recycling Food Waste
Recycling food waste not only fertilizes our soils but it also reduces soil erosion and prevents polluted storm water overflow from polluting our wetlands, lakes, and streams. It helps soil hold carbon dioxide.
The end result of your endeavors to recycle food waste is to end up with soil rich in nutrients. When this compost is used on fields, it has many benefits. It is an environment friendly replacement of chemical fertilizers because they significantly contribute in the production of nitrous oxide emissions.
“Nitrous oxide is a very powerful greenhouse gas which majorly contributes in global warming as it is about 310 times more powerful than carbon dioxide.”
Synthetic fertilizers have the disadvantage of containing concentrated forms of nitrogen and phosphorus which makes it harder for the plants to absorb them in comparison with the natural fertilizers. The nitrogen and phosphorus that the plants are not able to absorb then contaminates our rivers and streams.
Food recycling companies also use them to make organic fertilizers, generate heat, electricity and natural gas.
The Recycling Process of Food Waste
Recycling Food waste at home in your garden or backyard is one of the easiest and best ways to get all the benefits it has to offer. This will require less energy and less usage of fuel because collecting organic waste from each house in the locality and then processing it at a particular site will take extra energy and fuel than it will take at home.
When it comes to people who cannot compost at their homes and commercial food waste, there are food waste hauling companies that collect food waste from homes, food processing companies, beverage companies, restaurants, hotels, grocery stores and food services.
These companies then send this food waste to go through the process of anaerobic digestion to produce bio gas which helps in the production of heat and electricity as well.
Some farms and food industries get anaerobic digestion, heat recovery and electrical generation system installed on their premises which helps in recycling the food waste and generating heat and electricity which is then used by the industry.
Anaerobic Digestion System in Pennsylvania
Anaerobic digestion is the process of degrading organic materials without oxygen. The Anaerobic digestion system in Pennsylvania assists in saving the environment by making use of the gases that are released when food scrap decomposed. This process not only aids in the reduction in the emission of greenhouse gases but also helps in generating electricity.
