Title: recycling


1
recycling
  • Energy and waste management

2
Types of recycling
  • Closed loop recycling plastic bottles becoming
    new plastic bottles when the material collected
    is recycled into new material of the same type.
    Common with aluminum cans becoming new aluminum
    cans

  • Open loop recycling normally when products are
    recycled into different materials plastic
    bottles being downcycled into plastic tubing,
    pipes or polyester fiber to make clothes..

Recycling and energy saving
  • Recycling is a way to save energy in
    manufacturing new consumer goods.

8
Aluminum
  • One of the most efficient forms of recycling is
    aluminum recycling. Aluminum can be reused
    repeatedly and requires very little processing to
    make it available for reuse. Manufacturers simply
    melt down crushed aluminum stock and add it to
    freshly extracted aluminum without any
    degradation of quality in the finished product.
    According to the U.S. Environmental Protection
    Agency, recycling an aluminum can requires less
    than 5 percent of the energy that would be
    expended in creating a similar can out of fresh
    bauxite ore. The Aluminum Association estimates
    that the energy saved in recycling a single
    aluminum can could power a television for 3 hours.

9
Ok modelli.. Now something we can take notes on..
  • Recycling aluminum requires only 5 of the energy
    it would be required to manufacture an aluminum
    can from the bauxite ore..
  • Energy enough to power a TV for 3 hours! (that is
    a lot of xbox time)

10
  • recycled aluminum can comes back to the grocery
    store shelf as a new can in as little as 60 days
  • Aluminum cans are the most recycled item in the
    US
  • More aluminum is used to make cans than any other
    product
  • Because they are recycled at a high rates
    aluminum cans make up less than 1 of the waste
    in the US, that is awesome yo!
  • We use more than 80,000,000,000 aluminum cans
    every year

11
plastic
  • Seven major types of plastic are found in
    consumer products, and recycling can extend the
    use of most of them. Recycling plastic requires
    only a tenth of the energy needed to create new
    plastic from raw materials.

12
  • Americans (thats us) use 2,500,000 plastic
    bottles every hour! Most of them are thrown away
    stop that!
  • Plastic bags and plastic garbage thrown in the
    ocean kill as many as 1,000,000 sea creatures
    every year..
  • Recycling plastic saves twice as much energy as
    burning it into an incinerator
  • Americans (thats us again) throw away
    25,000,000,000 styrofoam coffee cups every year

paper
  • Recycling paper not only saves energy but also
    saves trees, reducing the amount of carbon
    dioxide present in the atmosphere. The EPA
    estimates that producing a recycled paper product
    requires only 60 percent of the energy required
    to create one from fresh wood pulp, and the
    Energy Administration Information reports that
    recycling a ton of paper can save 17 trees.
    Recycling paper also requires about half the
    water normally used in processing paper from
    virgin wood.

glass
  • Glass recycling is less efficient than many other
    forms of recycling, due to the processing
    required to return glass to a usable, raw state.
    According to the EPA, recycling glass only saves
    about 30 percent of the energy cost of producing
    new glass, and the raw materials required are in
    abundant supply. Reusing glass bottles and jars,
    however, requires no energy whatsoever, so you
    can reduce energy costs by finding new uses for
    these containers instead of simply throwing them
    out. Once you throw glass out, 1 million years
    will pass before that glass breaks down at the
    landfill

17
Each person creates about 4.7 pounds of waste
every single day In the US 33.4 of solid waste
is either recycled or composted, 12.6 is burned
in combustion facilities and 54 makes it's way
into landfills In 2007 99 of lead acid
batteries were recycled, 54 of paper and
paperboard were recycled, 64 of yard trimmings
are recycled and nearly 35 of metals were
recycled The amount of recycling in 2007 saved
the energy equivalent of 10.7 billion gallons of
gasoline and prevented the release of carbon
dioxide of approximately 35 million cars

  • The number of landfills in the US are decreasing
    while their size is increasing. In 1998 there
    were 8,000 landfills but only 1,754 in 2007
  • Each ton of mixed paper that is recycled can save
    the energy equivalent to 185 gallons of gasoline
  • Approximately 8,660 curbside recycling programs
    exist in the United States
  • There are about 3,510 community composting
    programs in the United States
  • Disposal of waste to landfills has decreased from
    89 in 1980 to 54 in 2007
  • Recycling 1 ton of aluminum cans conserves the
    equivalent of 1,665 gallons of gasoline
  • In 2007 the United States recycled and composted
    85 million tons of the 254 million tons of
    municipal solid waste created

21
  • Every month we throw out enough glass bottles and
    jars to fill out a giant skyscrapper
  • The energy saved from recycling 1 glass bottle
    can power a 100watt light bulb for 4 hours or a
    CFL for 20 hours
  • Causes 20 less air pollution and 50 less water
    pollution than making a new bottle from raw
    materials
  • A modern glass bottle will take over 4000 years
    to decompose and much longer if it is in a
    landfill
  • Mining and transporting materials to make glass
    produces 385 pounds of wasteif recycled glass is
    substituted for half of the raw materials and
    waste is reduced by 80
