SPI resin identification coding system

Grab a plastic container around you, it could be a water bottle, a food container, peanut butter container etc. Look at the bottom of the container, can you find a triangular symbol with a number in it?

Well, it is called SPI resin identification coding system.

The SPI resin identification coding system is a set of symbols placed on plastics to identify the polymer type. The primary purpose of the codes is to allow efficient separation of different polymer types for recycling. Separation must be efficient because the plastics must be recycled separately. Even one item of the wrong type of resin can ruin a mix.

You should know the identity of the symbols to have a good insight about the qualities and uses of plastics that you'll probably use daily. It is important to use these plastics appropriately according to their capacities as misuse of them may cause them to release toxic that will often cause cancer. Not all type of plastics can be reused.

Recycling number				Symbol	Abbreviation	Polymer name	Uses	Recycling
1				♳	PETE or PET	Polyethylene terephthalate	Polyester fibers (Polar Fleece), thermoformed sheet, strapping, soft drink bottles, tote bags, furniture, carpet, paneling and (occasionally) new containers. (See also: Recycling of PET bottles)	Picked up through most curbside recycling programs.
2				♴	HDPE	High-density polyethylene	Bottles, grocery bags, milk jugs, recycling bins, agricultural pipe, base cups, car stops, playground equipment, and plastic lumber	Picked up through most curbside recycling programs, although some allow only those containers with necks.
3				♵	PVC or V	Polyvinyl chloride	Pipe, fencing, shower curtains, lawn chairs, non-food bottles and children's toys.	Rarely recycled; accepted by some plastic lumber makers.
4				♶	LDPE	Low-density polyethylene	Plastic bags, 6 pack rings, various containers, dispensing bottles, wash bottles, tubing, and various molded laboratory equipment	LDPE is not often recycled through curbside programs, but some communities will accept it. Plastic shopping bags can be returned to many stores for recycling.
5				♷	PP	Polypropylene	Auto parts, industrial fibers, food containers, and dishware	Number 5 plastics can be recycled through some curbside programs.
6				♸	PS	Polystyrene	Desk accessories, cafeteria trays, plastic utensils, toys, video cassettes and cases, clamshell containers, packaging peanuts, and insulation board and other expanded polystyrene products (e.g., Styrofoam)	Number 6 plastics can be recycled through some curbside programs.
7				♹	OTHER or O	Other plastics, such as acrylic, nylon, polycarbonate, and polylactic acid (a bioplastic), and multilayer combinations of different plastics	Bottles, plastic lumber applications, headlight lenses, and safety shields/glasses.	Number 7 plastics have traditionally not been recycled, though some curbside programs now take them.

What to talk about?

Hey?
Actually each one of you may give me some tasks to accomplish. Because I really need something do to.
Because I'm  currently super-duper free!
I like it when things to do are tasks given by people. In this way, I'll take initiative to complete the particular task. It's even better if there's a deadline.


Here are some examples of tasks or things that you may request me to do:


- Draw a picture
You have to suggest me a title for the drawing.


- Play songs for you.
Give me the titles of the songs you would like to hear, and if it's a song that I don't know, it'd take some time for me to practise before presenting the song to you. You can give me a deadline in this case.


- Do research.
If there's something that you wish to find out more, you may request me to do some research for you based on the topic. I'll gather all the information and present it to you. It would save you a lot of time. ;) I can even give some explanation and tell you what I know if I'm familiar with that topic.


- Help you on your studies.
You can seek help from me if you face problems on your studies.
For your information, here's my qualifications :
   - UPSR            6A's
   - PMR             7A's
   - SPM             9A's
   - A-level        (Completed)
I'm particularly good at Chemistry, Biology and History.
You can also ask me about Mathematics, Additional Mathematics and English.
Kindly approach me if you have any doubt on your studies. I'm willing to give you good explanations for what you don't understand. :)


That's all I could think about, but I think there are more I can do. I'll be glad if I receive your tasks for me. ;)
I'll try my best to accomplish them.
Contact me via facebook!  Thanks!

What to talk about?

Hello everybody, I'm VWMH, or you can call me Black Vanessa. (Highlight the empty space to see what it is. :) )
I was born on August 17. I had graduated from high school and completed my A-level course. The next and final step of the education journey is to enter a University.


So I have just finished my exam for A-level recently.
Should I be happy about it?


Why be happy?
Because exam is over! I no longer have to engage in long hour study, which is really monotonous and tiring.
And I'll also have more time to do things that I like, such as playing Electone, playing violin, drawing, engage in facebook, singing, recording, taking pictures, sharing stories, fulfilling requests from people, entertaining people, learning new things, reading books other than textbooks, have sufficient sleep, do weird experiments, practise driving, hanging out with friends, socializing and many many more! Hehe, sounds interesting isn't it? :3


Why be sad?
Graduating from A-level indicates that you're going to leave the college soon, and end the Pre-University school life.
You have to start planning for University and your future.
You gotta be really decisive at this point, as this is a crucial point in life, which will also determine your future. And it's tough.


 Well, no matter what, let me enjoy my holidays first!
I'm going to accomplish what I have always wish to do. :D
