Landfills

Old (Closed) Landfills

Landfills will eventually meet
capacity and close.

  • Once closed, they no
    longer accept trash
    and must be monitored for 30 years.

  • Operators must comply
    with federal and state regulations
    throughout the entire process.

Hazardous waste

Anything with the terms flammable, poison, warning, corrosive, explosive, danger, pesticide, caustic, or acid. (Look on label for symbols).
Examples:

  • Latex or oil-based paint and items containing
    mercury, such as fluorescent lights and thermostats are also considered hazardous waste.

  • There are specific drop off locations for these wastes and they should never be placed in with the regular trash.

Hazardous waste

Improper disposal of these waste materials can:

  • Pollute the environment

  • Pose a threat to human health.

Household hazardous waste can cause:

  • Physical injury to sanitation workers

  • contaminate septic tanks or wastewater treatment systems if poured down drains or toilets.

  • They can also present hazards to children and pets if left around the house. Never allow hazardous waste to enter into a storm drain.

Electronic Waste (E-waste)

In the U.S. it is estimated that about 3 million tons of e-waste are generated each year.

  • This waste includes about 27 million units
    of televisions, 205 million units of computer
    products, and 140 million units of cell phones.

  • Less than 15 - 20% of the e-waste is
    recycled or refurbished;

  • e-waste constitutes less than 4% of
    total solid waste in the U.S

  • However, with growth in technological advancements many electronic products are
    becoming obsolete quickly, thus increasing the
    production of e-waste at a very rapid rate.
