Definition of waste as per MSW Rules 2000 "municipal solid waste" includes commercial and residential wastes generated in municipal or notified areas in either solid or semi-solid form excluding industrial hazardous wastes but including treated bio-medical wastes
Categorizationofwaste • high organic fraction • paper, glass, metals, plastic • rags • inert andothermaterials • Can be: • infectious, • hazardous 6. Bio-medicalwaste 1. Householdwaste(incl. offices, restaurants, hotels, SMEs, etc.) • multi material mix • valuable secondary resources, recycling options • extremely heavy and voluminous • possibly hazardous fraction • Can be: • toxic, • inflamable, • explosive, • corrosive, • reactive Categoriesofwaste 5. Hazardouswaste 2. Constructionanddemolitionwaste 4. E-waste 3. Plasticwaste • fast growing fraction of waste • requires appropriate processing • potentially harmful for workers and the environment • resource recovery • fast growing fraction of waste • high durability (centuries to thousands of years) • littering and choking of drainages and sewage systems • significant pollution of landscape, coasts and oceans • high recovery value, recycling options

Amount of urban waste in Maharashtra (2011) • MSW generation in India : • year 2000: 34 million tons (100%) • 2015: 83.8 million tons (x 2.5) • 2030: 221 million tons (x 2.6) • Per capita waste generation in cities: • 2010: 0.17 – 0.62 kg / day • projection 2030: 1.032 kg /day Source table: Sustainable Solid Waste Management in India; R.K.

Household waste • High organic fraction • Plastic (foils, cups, plates, bags,…) • Inert andothermaterials • Rags • Paper, glas, metals
Construction and demolition waste in India Itisestimatedthat C&DW accountstoapprox. 25% of solid wastegenerated in India • nearly 50% of C&DW are reused or recycled; • remainder is mostly landfilled; • common practice to pile waste form large construction or demolition projects in the roads causing traffic congestions; • C&DW from households normally goes to MSW making it heavy and degrading quality for further treatment Amountof C&DW generated • 40-60kg/m² during construction; • 40-50kg/m² during renovation and repair; • 300-500kg/m² during demolition; Source: http://www.waste-management-world.com/articles/print/volume-12/issue-5/features/rebuilding-c-d-waste-recycling-efforts-in-india.html Author: SadhanGhosh, President of the International Society of Waste Management, Air and Water (ISWMAW), India; and professor of Mechanical Engineering at Jadavpur University, Kolkata
Plastic Waste Increasefrom 7.5 milliontons in 2011upto 15 milliontons in 2015 (in India) • Waste plastics • •are causing littering and choking of sewerage systems; • • are often the most visible component in waste dumps and open landfills; • • are meanwhile significantly polluting the oceans; • in the oceans constitute a high risk for various groups of marine animals; • remain in the environment for decades to centuries *Source: Plastindia Foundation (2012)

Activity: Rating of MSWM in your hometowns • Rate the implementation / quality of services of MSWM in your municipality marking the specific rating score • The scores have the following meaning: • -2: item not existing • -1: item requires remarkable improvement • 0: situation reasonable • +1: good situation / performance • +2: best practice example, should be shared • Transfer your individual rating to the poster
