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.
