Waste management

  1. 1. What is waste management ? Waste management is the collection, transport, processing or disposal, managing and monitoring of waste materials. The term usually relates to materials produced by human activity, and the process is generally undertaken to reduce their effect on health, the environment. Waste management practices can differ for developed and developing nations, for urban and rural areas, and for residential and industrial producers. Management for non-hazardous waste residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while management for non-hazardous commercial and industrial waste is usually the responsibility of the generator subject to local, national or international controls.Waste Management  Page 2
  2. 2. The term waste generally entails an unwanted or unusable material that is deliberately discarded by its users.HouseholdsCommerce and IndustryAgricultureFisheriesSources of Waste  Page 3

  10. 10. Waste hierarchy - The waste hierarchy refers to the "3 Rs" reduce, reuse and recycle, which classify waste management strategies according to their desirability in terms of waste minimization. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste.Polluter pays principle - The Polluter Pays Principle is a principle where the polluting party pays for the impact caused to the environment. With respect to waste management, this generally refers to the requirement for a waste generator to pay for appropriate disposal of the unrecoverable material.Waste Management Concepts  Page 11

  13. 13. LANDFILLLandfill, or land-raise sites are currently the primary disposal route for all wastes in the UK, accounting for around 80% of the country’s waste stream. Most types of waste may be disposed of via landfill.In this process, the waste materials are brought to a particular place abandoned or unused, such as: quarries, mining voids or borrow pits. Then they are buried on the ground to get disposed with time.A properly designed and well-managed landfill can be a hygienic and relatively inexpensive method of disposing of waste materialsDesign characteristics of a modern landfill include methods to contain leachate such as clay or plastic lining material. Deposited waste is normally compacted to increase its density and stability, and covered to prevent attracting vermin (such as mice or rats). Many landfills also have landfill gas extraction systems installed to extract the landfill gas. Gas is pumped out of the landfill using perforated pipes and flared off or burnt in a gas engine to generate electricity.Methods of disposal  Page 14

  16. 16. COMPOSTINGComposting is a biological process in which micro-organisms convert biodegradable organicmatter into a stabilized residue known as compost. The process uses oxygen drawn from theair and produces carbon dioxide and water vapour as by-products . Composting  Page 17

  18. 18. IncinerationThe process of incineration involves the burning of waste materials. Incinerators usually transform the waste materials into heat, gas, steam and ashes. As this particular waste management system produces heat, therefore it is sometimes called thermal treatment.This waste management process is considered to be a practical method of disposing certain categories of harmful waste materials, such as medical waste materials.

  19. 19. Plasma GasificationPlasma gasification is another waste management process where gasified vessel utilizes to transform solid or liquid wastes into a syngas. This particular process of waste management results in the fundamental disposal of waste and other harmful materials. It is not only a very useful process of waste management, but also a great way of renewing power generation in an environmentally sustainable manner. Plasma Gasification  Page 20

  23. 23. RECYCLINGRecycling is a resource recovery practice that refers to the collection and reuse of waste materials such as empty beverage containers. The materials from which the items are made can be reprocessed into new products. Material for recycling may be collected separately from general waste using dedicated bins and collection vehicles, or sorted directly from mixed waste streams. Known as kerb- side recycling, it requires the owner of the waste to separate it into various different bins (typically wheelie bins) prior to its collection.The most common consumer products recycled include aluminium such as beverage cans, copper such as wire, steel food and aerosol cans, old steel furnishings or equipment, polyethylene and PET bottles, glass bottles and jars, paperboard cartons, newspapers, magazines and light paper, and corrugated fiberboard boxes.

  25. 25. An important method of waste management is the prevention of waste material being created, also known as waste reduction. Methods of avoidance include: Reuse of second-hand products. Repairing broken items instead of buying new. Designing products to be refillable or reusable (such as cotton instead of plastic shopping bags). Encouraging consumers to avoid using disposable products (such as disposable cutlery). Removing any food/liquid remains from cans, packaging and designing products that use less material to achieve the same purpose (for example, light weighting of beverage cans).Methods  Page 26
  26. 26. There are a lot of waste management methods available for disposal of different kinds of waste materials. While going to dispose these waste materials, in order to make the process easy, at first the waste materials are sorted out into various categories, such as:• Waste materials for landfill disposal• Plasma gasification• Incineration• And Recycling Depending on the type of material, different methods are used. Among all the existing waste management processes, waste management recycling is considered to be the best.Various methods  Page 27
