INTRODUCTIONo Solid Waste Management refers to handling of waste in Eco-friendly
way
o It is responsible for generated waste from source to disposal
o Municipal solid waste includes household wastes, commercial wastes and waste from street wash by a municipality
o Effectively managed by converting Waste into Wealth (W2W)
SANITATION + BUSINESS = SWM
OBJECTIVESThe main aim is to study the different concepts of Solid Waste Management in sub urban area
o To assess the quantity of solid waste generated
o To get pros and cons from people in SWM activities
o To check effectiveness of Landfill site
o To prepare business proposal for converting waste
ABSTRACTo Study area is Pattukkottai Municipality
o Our idea is to convert waste to wealth (W2W) and it helps in improve the sanitation for a hygienic environment
o Detailed Investigation – the quantity & the types of waste generated o Survey - to identify the problems faced by the local people & visitors
o Laboratory tests – to find out the suitable waste processing technique
o Determined the effectiveness of the Landfill site
o From the results obtained, we have decided to implement Vermi-composting Bio-degradable wastes Waste resale centre Non-bio-degradable wastes(Recyclable)
o Business Proposal was prepared
STUDY AREAo Area chosen for our case-study is Pattukkottai Municipality
