Our landfill expirement

A couple weeks ago Kayla and I did a landfil expirement to see what decomposed and what biodegrades. The hardest part of all of that was making sure that it was in good shape and to dry. I enjoyed the part where We tipped out the landfil and seen what has happened over a few weeks.

What to do with four sided shapes?

This week we are learning about quadrilaterals. The thing I found diffucult was drawing the different quadrilaterals and getting the right angles. My next step would to be to put in depth questions. 

What can plastic bags do to the environment?

                        This week we created a quiz about plastic bags and whatr can happen to them and what they can do. I found diffucult linking the different slides and finding the information. I think my next step is to include more information at the begining. 

Is that bottles you are wearing?

How can plastic bottles become clothing?

On this day when we recycle bottles it can somehow become clothing that you wear in everyday life. This step by step process is a complicated time consuming journey.

Firstly the workers shred the bottles because we may leave some liquid in the bottle without even realising. Once they are shredded they get wrapped in cellophane and sent over to China to continue the journey.

Once they are delivered to China the shredded parts with bright stickers have to get removed, to get rid of them they have to go in two different baths one after another. When they have finished the first bath they then need to go into the next bath which is dangerous for the human skin. When they have had their baths they need to dry out so they put it in an oven.

Once the bottles have dried out, the workers put the bottles into a rotation screw that can heat up to 270 celsius. When it has been through the rotation screw it has created thread but that thread isn’t yet strong enough to create cloth. So they have to stretch the thread and as they are stretching the thread it needs to be heated. Next the workers have to rip it all apart again, then it gets baled up and sent to another factory in China to make polyester which means that there job is done for now.

When they arrive to the other factory the workers have to scrap the thread to create very rough cloth. Then the rough cloth gets carded, carding is when the bonded fiber faces in a similar direction which will strengthen the material that it has created.

Once they have the material the workers use a machine that creates tiny loops into the material to give it a nice feel. Then after that for some strange reason they use steel brushes to get rid of the tiny loops that they just created so that it would be a softer feel to the product. Then they get the cloth and send it to a designer factory to finish off the product.  

When the designers have received the cloth they immediately get to work and design the product. When they have completed designing the product it gets sent all around the world.

When the product is complete they have to do that process all over again.  That has been the step by step process that the workers have been through. So the clothes you wear to this day started out as bottles and was transformed into clothes.
