  • *Waste & Waste Management

    Definition UU 18/2008 Sampah adalah sisa kegiatan sehari-hari manusia dan / atau proses alam yang berbentuk padat.

    The European Union waste is an object the holder discards, intends to discard or is required to discard.

    Basel Convention: "Substances or objects which are disposed of or are intended to be disposed of or are required to be disposed of by the provisions of international law" (Basel Convention).[1]

    United Nations Statistics Division (UNSD): "Wastes are materials that are not prime products (that is products produced for the market) for which the generator has no further use in terms of his/her own purposes of production, transformation or consumption, and of which he/she wants to dispose.

    Wastes may be generated during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, and other human activities. Residuals recycled or reused at the place of generation are excluded." [2]

    EFFECTS OF WASTE IF NOT MANAGED WISELY

    Affects our healthAffects our socio-economic conditionsAffects our coastal and marine environmentAffects our climate

    *EFFECTS OF WASTE

    GHGs are accumulating in Earths atmosphere as a result of human activities, causing global mean surface air temperature and subsurface ocean temperature to rise.

    Rising global temperatures are expected to raise sea levels and change precipitation and other local climate conditions.

    Changing regional climates could alter forests, crop yields, and water supplies.

    This could also affect human health, animals, and many types of ecosystems.

  • *Effects of waste.Activities that have altered the chemical composition of the atmosphere:

    Buildup of GHGs primarily carbon dioxide (CO2) methane (CH4), and nitrous oxide (N20).

    C02 is released to the atmosphere by the burning of fossil fuels, wood and wood products, and solid waste.

    CH4 is emitted from the decomposition of organic wastes in landfills, the raising of livestock, and the production and transport of coal, natural gas, and oil.

    N02 is emitted during agricultural and industrial activities, as well as during combustion of solid waste and fossil fuels. In 1977, the US emitted about one-fifth of total global GHGs.

    WHAT SHOULD BE DONE ?? We need waste management

    EARLY CONCEPTS OF WASTE DISPOSALThe traditional dilute and disperse approach to waste disposal is inadequate, given current population densities and levels of waste production.

    While concentrating and containing waste is an improvement over the old approach, containment is difficult to achieve.

    Though huge, the worlds largest landfills will be full relatively quickly.

    The waste disposal problem is a function of a large and growing waste volume and limited disposal space.

    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.

    INTEGRATED WASTE MANAGEMENT New strategies today focus on integrated waste management (IWM), emphasizing source reduction, reuse, recycling, composting, landfilling, and incineration.

    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.

    The Waste Management Hierarchy

    The waste hierarchy sets out the main methods for managing waste

    The preferred option is waste minimisation or reduction

    The next best option is re-use

    Recycling or composting come next

    Recovering value by other means follows on

    Landfilling comes last

  • Basic Thought Process of Reducing Waste (From "Osaka City General Waste Management Basic Plan" )

    1ReduceThe amount of waste generated in each of the production, distribution and consumption stages of a product must be minimized as much as possible.

    2ReuseReuse many times over items that are reusable, such as returnable bottles.

    3RecyclingOnce a product is beyond practical use or sentimental value, it is important to promote recycling as a means of reducing waste generation.

    4ThermalrecyclingWhen waste cannot be reused, burn it and use the heat.

    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.

    Colection

    Waste from Cleaning Public Spaces

    RecyclingThese recyclable resources are sent to private manufacturers and used for materials of various products.

    Sorting The collected recyclable waste is carried to places such as Tsurumi Recyclable Resources Sorting Center.

    Characteristics of wastesCorrosive: these are wastes that include acids or bases that are capable of corroding mental containers, e.g. tanks Ignitability: this is waste that can create fires under certain condition, e.g. waste oils and solventsReactive: these are unstable in nature, they cause explosions, toxic fumes when heated.Toxicity: waste which are harmful or fatal when ingested or absorb.

    Types of wasteNon Hazardous waste: refuse, garbage, sludge, municipal trash.Hazardous waste: solvents acid, heavy metals, pesticides, and chemical sludgesRadioactive: high and low-level radioactive wasteMixed waste: Radioactive organic liquids, radio active heavy metals. ( Moeller, 2005).
