Biodegradable and Non Biodegradable Waste

Biology | 7-14 yrs | Interactive

Before the Industrial Revolution, waste generated by our needs was low and mainly agricultural waste. Agricultural waste was further converted to either products like ropes, baskets, mats, roofing, fencing or animal feed and soil nutrients.

Industrial revolution and its requirements caused urbanisation, birth of cities and migration to cities. Growth in population in selected areas gave rise to excessive consumption, which in turn caused excessive generation of waste from factories which churned out products to meet our needs and from the work force employed to man factories in cities.

The huge quantities of waste generated over a period of time which could not be disposed has also been the cause of several epidemics.

Which leads us to ask several questions.

What is biodegradable waste?

Materials or Objects capable of being broken down or decomposed to smaller products by the action of living things (such as animals or microorganisms).

After being broken down they are easily absorbed into the soil to become nutrients or elements.

Identifying biodegradable waste

It is generally of plant, animal or mineral origin. It can be easily disposed by the action of microorganisms or animals. It can be broken down to base elements and is easily absorbed by the environment without damaging it.

Examples of biodegradable items

  • Food Waste
  • Animal And Human Excrement
  • Manure
  • Sewage
  • Slaughterhouse waste
  • Most paper products
  • Egg shells
  • Grasss
  • Flower/brush clippings

What is non biodegradable waste?

Materials or Objects not capable of being broken down or decomposed to smaller products by the action of living things (such as animals or microorganisms).

Since they cannot be broken down or decomposed they clutter the earth’s surface and and natural resources and are termed as POLLUTANTS.

Identifying non biodegradable waste

It is not of plant or animal origin or is of plant and animal origin but is processed and modified to change it’s basic natural composition. And hence cannot be broken down or decomposed to smaller products by the action of living things (such as animals or microorganisms).

Examples of non biodegradable items

  • Plastic Cups
  • Styrofoams Cups and Plates
  • Plastic bottles

What is waste management?

Waste management is collection, transportation, and disposal of garbage, sewage and other waste products. Waste management involves the process of treating solid wastes and recycling items that don’t belong to trash. It is about how garbage can be used as a valuable resource.
Reduce Reuse Recycle plays a very important part in waste management.

These are some of the things that can be recycled and reused.

  • Cardboard
  • Cooking Oil
  • Earth and Rubble
  • Electrical Appliances
  • Small Electrical Appliances and Electronic Products
  • Garden Waste
  • Glass Bottles & Jars
  • Household Batteries
  • Lead Acid (Vehicle) Batteries
  • Mixed Recycling
  • Mobile Phones
  • Oil
  • Paper
  • Pressurised Containers (gas bottles, fire extinguishers, etc)
  • Scrap Metal
  • Textiles
  • Tyres
  • Wood

Waste that cannot be Reduced, Reused or Recycled generally becomes a part of the environment and is around for 100s of years.
