When buying bottled water, you must check the bottom of the bottle,
in order to protect your health and environment. At the bottom of every
plastic bottles and containers there are recycling symbols. These
symbols are used to identify the type of plastic and recyclability of
the product. The symbol is a number, ranging from 1 to 7, within a
triangle. Using this recycling symbols, you can identify the safety of
the plastic. There are several types of plastics – some being safer than
others. Plastic bottles that are marked with the numbers 2, 4 and 5 are
the safer choices.
Below are 7 common recycling symbols and their meanings:
Number 1 Plastics — PET or PETE (polyethylene terephthalate)
It is most commonly used plastic found in water bottles and soft drinks
bottles. This type of plastic is intended for one time use. PETE plastic
should not be reused because cleaning detergents and high temperatures
can cause chemicals to leach out of the plastic into the water. These
chemicals can have a significant effect on our health. Recycling rates
of this plastic is relatively low (around 20 percent).
Number 2 Plastics — HDPE (high density polyethylene)
High-density polyethylene (HDPE) is a polyethylene thermoplastic made
from petroleum. HDPE is hard, opaque and can remain unaffected by high
temperatures. This plastic practically releases no chemicals, therefore
no health concerns for consumers. These bottles are highly recommended
by experts when buying bottled water. HDPE plastics also have one of the
highest recycling rates.
Number 3 Plastics — V (Vinyl) or PVC
Polyvinyl chloride (PVC) is a thermoplastic polymer. These type plastic
is commonly found in window cleaner and detergent bottles, shampoo
bottles, cooking oil bottles. Plastic bottles labeled with 3V or PVC is
highly hazardous and should be avoided. It discharges 2 toxic chemicals
that influence the hormones in body. These type of plastics are rarely
recycled.
Number 4 Plastics — LDPE (low density polyethylene)
Low-density polyethylene (LDPE) is a thermoplastic made from petroleum.
It can be found translucent or opaque. It is commonly found in
squeezable bottles. These plastics does not release any substances or
chemicals harmful for our health. Recycling rates of this plastic is
low.
Number 5 Plastics — PP (polypropylene)
Polypropylene (PP) is a thermoplastic polymer. It is strong, tough, has a
high heat resistance and low moisture intake. It is regarded as one of
the “safest” plastics produced today. PP is generally found in
squeezable bottles, syrup bottles, ketchup bottles, bottle caps, straws
and medicine bottles. This plastic is gradually becoming more accepted
by recyclers.
Number 6 Plastics — PS (polystyrene)
Polystyrene (PS) is a petroleum-based plastic. Polystyrene is widely
used in packaging materials and insulation. It is commonly found in
disposable plates and cups, egg cartons, carry-out containers, aspirin
bottles, compact disc cases. This type of plastic is difficult to
recycle and also been shown to release dangerous toxins over time into
anything packaged in it.
Number 7 Plastics — PC (Polycarbonate) or non-labeled plastic
It is the most dangerous plastic in the food production which releases
BPA chemicals and it is often used in the production of 3-5 gallon water
bottles and food containers. This plastics have traditionally not been
recycled.
