You’ve probably seen the recycling logo stamped on plastic items, often with a number inside and letters underneath. What do these elements signify?
Recycling Plastics – What Do the Numbers Mean?
On most plastic jars, containers and other packaging of products you buy, you’ll find what’s generally accepted as the recycling logo with a number in the middle and letters underneath stamped into the plastic.
The recycling logo can be a little misleading – just about anything can be recycled, but sometimes not without major effort. It’s a little bit like extracting oil from under the ocean bed compared to extracting oil from tar sands; none of it’s really good as such, but some plastics are far, far worse than others.
The Society of the Plastics Industry (SPI) implemented the system in 1988 to allow recyclers to be able to tell the different types of plastics when sorting. Basically, the numbers in the triangle indicate the grade of plastic – the resin ID code. This is the same system that you will find in many different countries.
Here’s what to look for when recycling and what it all means
1 – PETE – Polyethylene Terephthalate
The easiest of plastics to recycle. Often used for soda bottles, water bottles and many common food packages. Is recycled into bottles and polyester fibers.
2 – HDPE – High density Polyethylene
Also readily recyclable – Mostly used for packaging detergents, bleach, milk containers, hair care products and motor oil. Is recycled into more bottles or bags.
3 – PVC – Polyvinyl Chloride
This stuff is everywhere – pipes, toys, furniture, packaging – you name it. Difficult to recycle and http://www.greenlivingtips.com/articles/186/1/PVC-and-the-environment.html PVC is a major environmental and health threat.
4 – LDPE – Low-density Polyethylene
Used for many different kinds of wrapping, grocery bags and sandwich bags and can be recycled into more of the same.
5 – PP – Polypropylene
Clothing, bottles, tubs. Can be recycled into fibers.
6 – PS – Polystyrene
Cups, foam food trays, packing peanuts. Polysterene is a real problem as it’s bulky yet very lightweight and isn’t really worth recycling.
7 – Other
Could be a mixture of any and all of the above. Avoid it if you can – recyclers don’t want it.

The Green Living Tips logo of course! – sorry, couldn’t resist 🙂
So there you have it –
The recycling logo stamp on plastic isn’t a guarantee that the item is easily recyclable and in some cases, it’s not at all. Look for products where the packaging has a 1 or 2 stamp whenever you can.
Remember, your effort does make a difference.
