Residuals recycled or reused at the place of generation are excluded."

In 1977, the US emitted about one-fifth of total global GHGs.</p><p>Inventory of US Greenhouse Gas Emissions and Sinks: 1990-2000, US EPA, Office of Atmospheric Programs, April 2002 EPA 236-R-02-003.</p><p>WHAT SHOULD BE DONE ?? We need waste management</p><p>EARLY CONCEPTS OF WASTE DISPOSALThe traditional dilute and disperse approach to waste disposal is inadequate, given current population densities and levels of waste production.</p><p>While concentrating and containing waste is an improvement over the old approach, containment is difficult to achieve.</p><p>Though huge, the worlds largest landfills will be full relatively quickly.</p><p>The waste disposal problem is a function of a large and growing waste volume and limited disposal space.</p><p>MODERN TRENDSDisposal is not the only problem with waste; disposed wastes represent underutilized resources.Industrial ecology considers waste as resources out of place; this type of thinking encourages recycling and reuse, and thus reduce disposal and associated waste problems.The zero waste movement seeks to eliminate discharges to the environment.Many waste management techniques present a risk to public health, pose a nuisance, or merely move the waste from one site (or environmental medium) to another.</p><p>INTEGRATED WASTE MANAGEMENT New strategies today focus on integrated waste management (IWM), emphasizing source reduction, reuse, recycling, composting, landfilling, and incineration.</p><p>Waste Management Waste management is the collection, transport, processing, recycling or disposal of waste materials, usually ones produced by human activity, in an effort to reduce their effect on human health. Waste management can involve solid, liquid, or gaseous substances with different methods of disposing with for each. </p><p>The Waste Management Hierarchy</p><p>The waste hierarchy sets out the main methods for managing waste</p><p>The preferred option is waste minimisation or reduction </p><p>The next best option is re-use</p><p>Recycling or composting come next </p><p>Recovering value by other means follows on</p><p>Landfilling comes last</p></li><li><p>Basic Thought Process of Reducing Waste (From "Osaka City General Waste Management Basic Plan" )</p><p>1ReduceThe amount of waste generated in each of the production, distribution and consumption stages of a product must be minimized as much as possible.</p><p>2ReuseReuse many times over items that are reusable, such as returnable bottles.</p><p>3RecyclingOnce a product is beyond practical use or sentimental value, it is important to promote recycling as a means of reducing waste generation.</p><p>4ThermalrecyclingWhen waste cannot be reused, burn it and use the heat.</p><p>5Appropriate treatmentItems which have been through the preceding efforts and must be discharged as waste must be treated and handled so as to minimize the burden it places on environment.</p><p>Colection</p><p>Waste from Cleaning Public Spaces </p><p>RecyclingThese recyclable resources are sent to private manufacturers and used for materials of various products.</p><p> Sorting The collected recyclable waste is carried to places such as Tsurumi Recyclable Resources Sorting Center.</p><p>RECYCLE PLAZA</p><p>Incineration Plant</p><p>4.Reclamation 3.Unloading 1.Loading 2.Transporting </p><p>LANDFILL SIDES</p><p>THANK U</p><p>Waste16 June 2010Waste Management.ppt*Municipal solid wastePaperYard trimmingsFood scrapsPlasticsMetalsTextiles, leather, rubberWoodGlassmore</p><p>Waste Management.ppt</p><p>WasteMinimizing Municipal solid wasteMinimizing packagingRecycleablePaper, plastics, metals, glass, wood Reusable ?
