Food waste decomposing

Decomposers facilitate decomposition mostlyWhat does decomposer mean? This term is used to refer to the organisms that get nutrients from dead animal materials or plants.  As these microorganisms break down the dead and decaying animals or plants to obtain nutrients from them, decomposition takes place naturally. Decomposers play a vital role in the environment since they help in getting rid of the dead organisms from the environment. What would happen to an ecosystem if the decomposers disappeared? Firstly, every living organism dies at some point, and without decomposers, there would be piles of dead organisms all over. Secondly, decomposers break down the dead organisms to release nutrients into the soil; so that means without decomposers there would be no soil to grow plants on. Animals such as herbivores survive on plants, implying they would not exist as well. Humans depend on plants and animals as their source of food and thus would not live too. This explains that without decomposers the ecosystem would not be complete and therefore no living things would live.


Food wastes such as vegetables, left overs, stale food, fruits and so many others are a daily occurrence in almost every household. Composting these food scraps would be a good way of getting rid of this waste for the following reasons:

  • It is the most effective ways of reducing waste from the landfills as well as the waterway. Composting turns the waste into soil which is more useful than the waste being accumulated on landfills.
  • If you have a garden, getting fertilizer from kitchen wastecan help you save money. You will not need to buy chemical fertilizers as composting enriches the soil with nutrients.
  • Chemical fertilizers are not environment-friendly. Composting will help to spare the environment by proving the soil with natural nutrients from the dead organisms.

Food waste that you should not compost

  • Bones or any other meat waste
  • Fish waste
  • Any grease and oils
  • Cheese, butter, cottage, or any other dairy product

Why you cannot compost the above food wastes

  • They cause an imbalance in the nutrient structure of other food waste making them break down or rather decompose slowly.
  • Scavengers and rodents are attracted by this kind of food waste
  • The meat will attract maggots
  • Your bin will produce an awful smell as these waste foods rot


What you need to know about composting at home

  • Before you start composting food waste in your home, you need to check with your country’s municipality to see if they allow it. Some might not permit it since it attracts rodents and other scavengers
  • Your compost will require the following for the food waste to decompose successfully: carbon, air, moisture, and nitrogen.
  • To get carbon, you will need dead-plant materials such as leaves or twigs. Newspapers too can work.
  • To get nitrogen, you will require vegetables or fruits waste.
  • Air and moisture will be necessary for the decomposers to start the decomposing process. These will either be fungi, insects or bacteria decomposers.


Methods that can be used to decompose food waste

  1. Food waste disposers– They are also known as garbage decomposer units and mostly installed under the kitchen sink where they shred the food wastes into liquid waste that is passed down to the sewage.  These units are of great importance to both the homeowner and the local authorities. This is because of the following advantages:

-Food waste is separated efficiently in the households.

-Kerbside collections will not be required

-Reduced contaminations of cross waste streams

-They provide a source of  nutrients to the soil and renewable energy

-Less space will be required for landfills


  1. Worm composting

If you do not have enough space outside your house, you can use this composting on your balcony efficiently. Worm composting is one of the cleanest and easiest ways of decomposing food waste in a home. It comes with a tin with a lid and with worms inside it. The worms will break down the food scraps as they try to eat them and thus facilitate decomposition to take place. Some of the best food waste that can be composted using this method include; bread, pasta, rice, crushed egg shells, fruit, and vegetables.

  1. Backyard composting

This will apply to the people with a backyard or enough space around their home that they can spare to create a heap for the food waste. After you have dumped the waste from your kitchen into the pit for some time, the pile will be high enough to trap heat inside there. As a result of the increased temperatures, the cultures will multiply faster which will reduce the time taken for decomposition to take place.

  1. Municipal composting

Some cities have massive compost that the people living around can use to get rid of their food waste or any other type of garbage. This type of waste decomposer sorts, shreds and arrange the waste into long rows that allow enough oxygen to circulated in between the trash.  The temperatures and moisture in this compost is regulated to levels that facilitate decomposition to take place.

This type compost is effective to food waste such as meat, fish and dairy products which most compost cannot handle due to various reasons as mentioned before. The final product is mostly used for agriculture uses.
