.The Importance of Source Segregation –
Source Segregation in India is an important factor we need to promote and execute for waste management in all the areas to get the least landfill in the coming years.
Waste segregation is divided into two – bio-degradable and non-bio degradable wastes.
Bio-degradable wastes – fruits, vegetables, flowers, grasses, leaves and wood or pencil shavings.
non-bio degradable wastes – we have paper, plastics, glass, metal, tetra packs and aluminum foil.
But If the waste is not segregated properly, all the waste will mix up and dump in the landfill and finally there will be harmful gas generated and mixed up in the air and will pollute the environment.
And there is lot of chance for methane gas to generate which is very harmful and dangerous for humans, if the waste is not segregated properly.
Source Separation starts from the Kitchen
• Source Separation of waste is the best way to recycle. Relies on separation where the waste is produced instead of trying to separate it out later
• Rather start with the food waste and then move onto other waste streams instead of the other way around
• Low-cost sorting method which is an easy way to implement.
The Benefits of Source Seggregation
Extract Energy – Anaerobic Digestion
Recover nutrients to enrich soils
Save landfill space
Compost can be used for soil erosion prevention, land rehabilitation, grow food
Control generating of Methane
Less space occupies for landfills
Makes recycling easier in more hygienic way for staff
control bad odours
Solid waste includes domestic and commercial waste, industrial waste, hospital waste, e-waste and construction debris.
Waste segregation –
It is divides waste into dry and wet. Dry waste includes wood and related products, metals and glass. Wet waste typically refers to organic waste usually generated by food.
i) Domestic and commercial waste – Compostable, recyclable ii) Industrial waste – non-hazardous and hazardous iii) Hospital/biomedical waste – non-hazardous and hazardous iv) E-waste – recyclable and non-recyclable v) Construction debris – reusable as building material
About food waste –
FOOD WASTE is composed of raw or cooked food materials and includes food loss before, during or after meal preparation in the household, as well as food discarded in the process of manufacturing, distribution, retail and food service activities All food waste should be separated from general waste and storage in specific containers and/or bins. And this separation prevents other waste streams from being contaminated, making it easier to recycle all streams (cardboard, plastics, food, etc.).Food waste must be stored appropriately in accordance with food hygiene principles and food safety guidance prior to collection, particularly if containers need to be stored in outdoor areas. Ideally this would be away from the immediate kitchen area.
Containers should not be overfilled and should be regularly cleaned in order to minimise the potential for spills, which may be a slipping hazard as well as causing odour.
Segregation of our waste is essential as the amount of waste being generated today causing immense problem. There are certain items are not Bio Degradable but can be reused or recycled in fact it is believed that a larger portion of the waste can be recycled, a part of can be converted to compost, and only a smaller portion of it is real waste that has no use and has to be discarded.
