Railway Science (Environment – Environmental Wastes)

Nonbiodegradable waste: Decays at a relatively slow pace and keeps on accumulating. The cost of disposal of nonbiodegradable waste is high. Examples: Electronic waste, Plastic  waste, Nuclear waste, Artificial rubber, Polymer, Batteries etc. Methods to disposal : Recycling, Pyrolysis, Incineration, Sanitary landfills, Encapsulation, etc.

Micro Bacteria involved in the biodegradation process are Pseudomonas Mycobacterium, Sphingomonas, Bacillus, and Achromobacter. A large amount of microbial flora around the wastes is produced which may increase the risk of communicable diseases in humans, plants, and animals caused by microbes.

Non Bio Biodegradable Waste - It is defined as a substance that cannot be decomposed or dissolved naturally and acts as a source of pollution. Ways to reduce non-biodegradable wastes: Recycling, Use of Jute bags, Reuse, etc.

Non Bio Biodegradable Waste - It is defined as a substance that cannot be decomposed or dissolved naturally and acts as a source of pollution. Ways to reduce non-biodegradable wastes: Recycling, Use of Jute bags, Reuse, etc. Biodegradable Waste - Any organic waste that can be degraded by microorganisms into simpler compounds.

Biodegradable substances can be easily decomposed by naturally occurring agents such as oxygen, water, ultraviolet rays etc. Examples: Peels of vegetables, Stale bread, Stale biscuits, Egg shells, Peels of fruits, Paper, Fruits.

Plastics pollute our land and water, made from non-renewable resources, composed of very resistant synthetic polymers that never break down, harmful to wildlife and marine life & human health, not easy to recycle. Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. They are lightweight, durable, flexible, and inexpensive to produce. Most plastics contain organic polymers.

Recycling: The process of collection and conversion of waste into useful and new products. Benefits: in reducing air, land, water and soil pollution, in conserving natural resources and saving energy.

Waste segregation can be defined as the process of identifying, classifying, dividing and sorting of garbage and waste products in an effort to reduce, reuse and recycle materials.
It decreases the amount of waste going to landfill. Segregation helps in reducing the expenditure incurred on disposal of waste.
This is helpful in identifying items that can be sold to generate revenue. It saves items from being thrown away that are suitable for recycling.

Kitchen Waste composting is the act of using kitchen waste and food scraps to create compost beneficial for enriching soil and growing plants and crops. Compost - A mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical and biological properties. It is commonly prepared by decomposing plant, food waste, recycling organic materials and manure.
