Answer:
Plastic is an essential component of many items, including water bottles, combs, and beverage containers. Knowing the difference, as well as the SPI codes, will help you make more informed decisions about recycling.
The seven types of plastic include:
Polyethylene Terephthalate (PETE or PET)
High-Density Polyethylene (HDPE)
Polyvinyl Chloride (PVC)
Low-Density Polyethylene (LDPE)
Polypropylene (PP)
Polystyrene or Styrofoam (PS)
Miscellaneous plastics (includes: polycarbonate, polylactide, acrylic, acrylonitrile butadiene, styrene, fiberglass, and nylon)
When it comes to promotional giveaways, and even items we use around the house, there is no material more important than plastic. The same can be said for the items we use at the office. Most of our supplies contain at least a little bit of this material. In fact, humans have thus far produced 9.1 billion tons of plastic!
For the sake of the environment, it's important to know the different plastic types and their uses, as well as the resin identification codes found on each. This will help you make informed decisions when it comes to recycling.
Recycling Codes for Plastic
Understanding the plastic types can help consumers like you make more informed decisions related to your health and the environment. In addition, it's important to become familiar with an item's SPI (Society of the Plastics Industry) code, which is also known as a resin identification number and is used to classify the different types of plastic. This information will help you sort plastic materials more effectively for recycling.
The Society of the Plastics Industry (SPI) established a classification system in 1988 to allow
consumers and recyclers to identify different types of plastic. Manufacturers place an SPI code, or
number, on each plastic product, usually moulded into the bottom. This guide provides a basic outline
of the different plastic types associated with each code number.
Polyethylene Terephthalate sometimes absorbs odours and
flavours from foods and drinks that are stored in them. Items
made from this plastic are commonly recycled. PET(E) plastic is
used to make many common household items like beverage
bottles, medicine jars, rope, clothing and carpet fibre.
High-Density Polyethylene products are very safe and are not
known to transmit any chemicals into foods or drinks. HDPE
products are commonly recycled. Items made from this plastic
include containers for milk, motor oil, shampoos and conditioners,
soap bottles, detergents, and bleaches. It is NEVER safe to reuse
an HDPE bottle as a food or drink container if it didn’t originally
contain food or drink.
Polyvinyl Chloride is sometimes recycled. PVC is used for all
kinds of pipes and tiles, but is most commonly found in plumbing
pipes. This kind of plastic should not come in contact with food
items as it can be harmful if ingested.
Low-Density Polyethylene is sometimes recycled. It is a very
healthy plastic that tends to be both durable and flexible. Items
such as cling-film, sandwich bags, squeezable bottles, and plastic
grocery bags are made from LDPE.
Polypropylene is occasionally recycled. PP is strong and can
usually withstand higher temperatures. It is used to make lunch
boxes, margarine containers, yogurt pots, syrup bottles,
prescription bottles. Plastic bottle caps are often made from PP.
Polystyrene is commonly recycled, but is difficult to do. Items
such as disposable coffee cups, plastic food boxes, plastic cutlery
and packing foam are made from PS.
Code 7 is used to designate miscellaneous types of plastic not
defined by the other six codes. Polycarbonate and Polylactide are
included in this category. These types of plastics are difficult to
recycle. Polycarbonate (PC) is used in baby bottles, compact discs,
and medical storage containers.
