  • Remediation of solide waste landfill

    1. 1. Waste  Non-liquid, non-soluble materials ranging from municipal garbage to industrial wastes that contain complex and sometimes hazardous substances.  Solid wastes also include sewage sludge, agricultural refuse, demolition wastes, and mining residues.  Technically, solid waste also refers to liquids and gases in containers
    2. 2.  Waste: Any material that is discarded, served its intended purpose, or is a manufacturing or mining byproduct  Solid Waste: Everything not covered by the Clean Air and Water Acts, including solids, liquids and gases (RCRA is a catch all) What is Solid Waste
    3. 3.  Solid waste means any garbage, refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded materials including solid, liquid, semi-solid, or contained gaseous material, resulting from industrial, commercial, mining and agricultural operations, and from community activities
    4. 4.  Solid wastes are any discarded (abandoned or considered waste-like) materials. Solid wastes can be solid, liquid, semi-solid or containerized gaseous material. In Simple Words
    5. 5.  waste tires  septage  scrap metal  latex paints  furniture and toys  domestic refuse (garbage)  discarded appliances and vehicles  uncontaminated used oil and anti-freeze  empty aerosol cans, paint cans and compressed gas cylinders  construction and demolition debris, asbestos Examples of solid wastes:
    6. 6.  Environmentally acceptable disposal of waste on ground. Sanitary landfills are where non-hazardous waste is spread in layers, compacted, and covered with earth at the end of each working day. Secure landfills are those where hazardous waste is disposed of by burial, in holes or trenches in ground lined with impervious plastic sheeting to prevent leakage or leaching of dangerous substances into soil and water supply. What is Landfill

    8. 8. Transfer Station/Disposal Site
    9. 9.  Protect human health and the environment from the potential hazards of waste disposal  Conserve energy and natural resources  Reduce the amount of waste generated  Ensure that wastes are managed in an environmentally sound manner Resource Conservation and Recovery Act
    10. 10.  Hazardous Waste: manages hazardous waste from the time it is generated until it is disposed (referred to as cradle to grave)  Solid Waste: sets criteria for municipal solid waste and other non-hazardous waste disposal facilities and prohibits open dumping of solid waste  Underground Storage Tank: regulates underground storage tanks storing petroleum or other hazardous substances
    11. 11. INTEGRATED WASTE MANAGEMENT  Source Reduction  Recycling and Composting  Combustion (Waste-to-Energy)  Landfills
    12. 12.  Waste Management and Remediation Division is responsible for monitoring and controlling the generation, treatment, storage, and disposal of wastes. On the remediation side, program resources are directed to responding to releases of hazardous substances to surface waters, ground water, or soils. Waste Management & Remediation
    13. 13.  Waste remediation is a process in which contaminants are removed or neutralized so that they cannot cause harm. It may entail actively removing the waste, which is generally preferable, or isolating or containing the waste on-site because it too costly or impractical to remove. Waste Remediation
    14. 14. Light Weighting  The process of reducing the amount of a particular material per unit of product is known as light weighting
    15. 15. Where does our trash go? In 2007 almost 65% of the solid wastes produced in U.S. went to 2,500 sanitary landfills.
    16. 16. Landfilling  Landfilling is the term used to describe the process by which solid waste and solid waste residuals are placed in a landfill  Waste dumps or uncontrolled land disposal sites  Secure landfills for Hazardous Waste a) After geo- membrane liner has been installed b) After two lifts of solid waste c) Landfill with final cover
    17. 17. Incinerators – burn trash 17% of trash is burned in U.S. Japan and Switzerland burn more than 50% of their trash.
    18. 18.  Storage tanks are used to store petroleum or certain other hazardous liquids. Leaking USTs can pose a serious environmental threat if the stored petroleum or other hazardous substance seeps into the soil and contaminates ground water, which is the source of most drinking water. Storage Tanks
    19. 19. For a Cleaner Tomorrow
    20. 20.  Recycling is the process of transforming waste materials into usable resources. It is preferable to treatment and disposal because it helps conserve energy and reduce waste. Recycling, like garbage collection, is an optional service provided at the discretion of local governments or by private recycling companies. Recycling
