    • DEFINITIONS
      • According to the 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 national law" (Basel Convention).
      • Produced by the 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."
      • The European Union defines waste as an object the holder discards, intends to discard or is required to discard.
      • Waste Management Licensing Regulations 1994 defines waste as: any substance or object which the producer or the person in possession of it, discards or intends or is required to discard but with exception of anything excluded from the scope of the Waste Directive.
    • INTRODUCTION
      • Unavoidable by-product of most human activity.

    • TYPES OF WASTES
      • Generation and Characteristics
      • Municipal Solid Waste
      • Industrial Solid Waste
      • Agricultural Waste and Residues
      • Hazardous Waste
      • Nuclear Waste
    • Municipal solid waste
      • Municipal solid waste (MSW) is generated from households, offices, hotels, shops, schools and other institutions. The major components are food waste, paper, plastic, rags, metal and glass, although demolition and construction debris is often included in collected waste, as are small quantities of hazardous waste, such as electric light bulbs, batteries, automotive parts and discarded medicines and chemicals.
    • Industrial Solid Waste
      • Industrial solid waste in the Asian and Pacific Region, as elsewhere, encompasses a wide range of materials of varying environmental toxicity. Typically this range would include paper, packaging materials, waste from food processing, oils, solvents, resins, paints and sludges, glass, ceramics, stones, metals, plastics, rubber, leather, wood, cloth, straw, abrasives, etc.
    • Agricultural Waste and Residues
      • Expanding agricultural production has naturally resulted in increased quantities of livestock waste, agricultural crop residues and agro-industrial by-products.
    • Hazardous Waste
      • A hazardous waste is waste that poses substantial or potential threats to public health or the environment. There are four factors that determine whether or not a substance is hazardous:
      • ignitability (i.e., flammable)
      • reactivity
      • corrosivity
      • toxicity
    • Nuclear Waste
      • Nuclear waste is the radioactive waste left over from nuclear reactors, nuclear research projects, and nuclear bomb production. Nuclear waste is divided into low, medium, and high-level waste by the amount of radioactivity the waste produces.
    • B. Environmental Impacts of Waste
      • Nature's price- effect of chemicals and hazardous waste on soil and water conditions.
      • Animals- effect of chemicals on wildlife and food cycles.
      • Heath- waste accumulation breeds bacteria and is a good breeding area for vectors e.g. mosquitoes.
      • Eye sore to man - destruction of the beauty and tranquility of the earth.
      • Economy- the long term effects of waste on the environment are hard to see so it is much easier to ignore our waste now and leave the future generation to literally pay the price.
    • Waste processing and control
      • Collection and Transfer
      • door-to-door collection
      • indirect collection - containers, communal bins placed near markets, in residential areas and other appropriate locations.
      Municipal Solid Waste/ Industrial Solid Waste
      • (b) Material Recovery, Reuse and Recycling
      • Recycling involves processing used waste materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for &quot;conventional&quot; waste disposal, and lower greenhouse gas emissions as compared to virgin production.
      • (c) Disposal Methods for MSW/ISW
      • Open Dumping
      • Land filling
      • Incineration
    • Open Dumping
      • Most widespread method of solid waste disposal
      • Uncontrolled disposal of waste without measures to control leachate, dust, odor, landfill gas or vermin.
      • Open burning of waste is practiced at dumpsites.
      • Waste is dumped along the shoreline and into the sea.
      • Drawbacks :
      • scarcity of available land.
      • build-up of landfill gas (predominantly methane), which can led to outbreaks of fire and adverse health effects on workers and adjacent residents.
    • Landfilling
      • disposal of waste materials by burial
      • Its impacts includes,
      • - fatal accidents
      • - infrastructure damage
      • - pollution of local environment
      • - Off gassing of landfill gas (Methane)
      • - harboring of disease vectors
    • Incineration
      • Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials.
      • Incineration of waste materials converts the waste into ash, flue gas, and heat.
      • Incinerators reduce the mass of the original waste by 80–85 % and the volume by 95-96 %.
    • Bio-Medical Waste
      • ‘ Bio-medical waste’ means any solid and/or liquid waste including its container and any intermediate product, which is generated during the diagnosis, treatment or immunization of human beings or animals or in research pertaining thereto or in the production or testing thereof.
      • It differs from other hazardous waste because of its source of generation.
    • Environmental Concern
      • The following are the main environmental concerns with respect to improper disposal of bio-medical waste management:
      • Spread of infection and disease through vectors (fly, mosquito, insects etc.) which affect the in -house as well as surrounding population.
      • Spread of infection through contact/injury among medical/non-medical personnel and sweepers/rag pickers, especially from the sharps (needles,blades etc.).
      • Spread of infection through unauthorized recycling of disposable items such as hypodermic needles, tubes, blades, bottles etc.
      • Reaction due to use of discarded medicines
      • Toxic emissions from defective/inefficient incinerators.
      • Indiscriminate disposal of incinerator ash / residues.
    • E-Waste
      • Electronic waste, e-waste, e-scrap, or Waste Electrical and Electronic Equipment (WEEE) describes loosely discarded, surplus, obsolete, or broken electrical or electronic devices.
      • Some electronic scrap components, such as CRTs, contain contaminants such as lead, cadmium, beryllium, mercury, and brominated flame retardants.
    • Effects on environment and human health
      • Computer wastes that are landfilled produces contaminated leachates which eventually pollute the groundwater. Acids and sludge obtained from melting computer chips, if disposed on the ground causes acidification of soil.
      • Incineration of e-wastes can emit toxic fumes and gases, thereby polluting the surrounding air.
      • Improperly monitored landfills can cause environmental hazards.
      • The most dangerous form of burning e-waste is the open-air burning of plastics in order to recover copper and other metals.
    • Responsibilities of the Citizen
      • Waste prevention is perhaps more preferred to any other waste management option including recycling. Donating electronics for reuse extends the lives of valuable products and keeps them out of the waste management system for a longer time. But care should be taken while donating such items i.e. the items should be in working condition.
      • Reuse, in addition to being an environmentally preferable alternative, also benefits society. By donating used electronics, schools, non-profit organizations, and lower-income families can afford to use equipment that they otherwise could not afford.
      • E-wastes should never be disposed with garbage and other household wastes. This should be segregated at the site and sold or donated to various organizations.
      • While buying electronic products opt for those that:
        • are made with fewer toxic constituents
        • use recycled content
        • are energy efficient
        • are designed for easy upgrading or disassembly
        • utilize minimal packaging
        • offer leasing or take back options
        • have been certified by regulatory authorities. Customers should opt for upgrading their computers or other electronic items to the latest versions rather than buying new equipments.
    • Waste hierarchy
      • The waste hierarchy refers to the 3Rs of reduce, reuse and recycle, which classify waste management strategies according to their desirability. The 3Rs are meant to be a hierarchy, in order of importance.
      • The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste.
    • Re-thinking Waste
      • Reduce - to buy less and use less. Incorporates common sense ideas like turning off the lights, rain barrels, and taking shorter showers, but also plays a part in Composting/Grasscycling (transportation energy is reduced), low-flow toilets, and programmable thermostats. Includes the terms Re-think, Precycle, Carpool, Efficient, and Environmental Footprint/Foodprint.
      • Reuse - elements of the discarded item are used again. Initiatives include Hand-Me-Downs, Garage Sales, Quilting, and Composting (nutrients). Includes the terms Repair, Regift, and Upcycle.
      • Recycle - discards are separated into materials that may be incorporated into new products. This is different from Reuse in that energy is used to change the physical properties of the material. Initiatives include Composting, Beverage Container Deposits and buying products with a high content of post-consumer material.
      • Generate - capturing useful material for waste to energy programs. Includes Methane Collection, Gasification and Digestion, and the term Recover.
      • Incinerate - high temperature destruction of material. Differs from Gasification in that oxygen is used; differs from burning in that high temperatures consume material efficiently and emissions are controlled.
    • Waste Treatment Technologies
      • Composting
      • Anaerobic digestion
      • Gasification
      • Waste autoclave
    • Composting
      • treating solid waste in which organic material is broken down by microorganisms in the presence of oxygen to a point where it can be safely stored, handled and applied to the environment.
      • essential part of reducing household wastes, garden wastes.
      • can be done inexpensively by every household and produce a product -- finished compost or humus -- that can benefit the environment as a natural fertilizer for gardening and farming.
    • Anaerobic digestion
      • Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen, used for industrial or domestic purposes to manage waste and/or to release energy.
      • Anaerobic digestion is widely used as a renewable energy source because the process produces a methane and carbon dioxide rich biogas suitable for energy production, helping to replace fossil fuels. The nutrient-rich digestate which is also produced can be used as fertilizer.
    • Gasification
      • Gasification is a process that converts carbonaceous materials, such as coal, petroleum, biofuel, or biomass, into carbon monoxide and hydrogen by reacting the raw material, such as house waste, or compost at high temperatures with a controlled amount of oxygen and/or steam. The resulting gas mixture is called synthesis gas or Syn-gas and is itself a fuel. Gasification is a method for extracting energy from many different types of organic materials.
    • Waste autoclave
      • solid waste treatment that utilizes heat, steam and pressure of an industrial autoclave in the processing of waste.
      • waste autoclaves process waste in batches. Saturated steam is pumped into the autoclave at temperatures around 160°C. The pressure in the vessel is maintained at 5 bar gauge for a period of up to 45 minutes to allow the process to fully 'cook' the waste.
      • The autoclave process gives a very high pathogen and virus kill rate.
