Giving packaging new life
Very straight forward to the point, although in today's day in age majority of designers and even the average joe already know these recycling facts. that being said there are some things said such as the methods used to recycle them that people to not know about, if these were described in more detail it would be better. It is VERY good how they have the video following the process of what is happening, when these methods are just verbally said to somebody they do not understand them, but when a video of the process is shown it makes it much easier to understand.
i did find the recycling of plastics the most interesting video as there is a different method of recycling for each individual plastic.
the statistical fact at the end also comes in useful as it gives the viewer a vivid understanding of how good or bad this technique is as it usually explains how commonly it is done.
How its made
Cardboard boxes: did not mind the video, already know most of it, all except for how the "flute" was made, along with that i was not aware of some of the terminology. I was also incredibly impressed at what rate they all shoot out at.
packaging tubes: was interested about the "aluminum slugs" i always thought it was fed in at a pellet or grain like form, melted, and then molded. i am truely amazed by forcing the tube out into that shape. I would think that it would require too much energy to push it out like that, but now that i think about it i suppose it would use more energy than having to melt the thing. i really liked this video, i learnt alot
aluminium cans: was and have been for a long time highly aware of this method. i have always found it most interesting how the machine will do its job of punching it, then all the excess material is sent back to the melting factory, ints just interesting how this material is always being sent too and from just to save money, that being said it VERY good that the material is not simply being thrown out. most implressed by the rate of whiche the cans are made, 1800 hundred cans per minute, amazing.
plastic bottles: i have known this method for a long time, and knowing that PET bottles are used very commonly in this world it is a reality that this method is very commonly used. i learnt MORE about this method in my materials and tech C class. what i find most interesting is the size of the preforms before they are blown out. again impressed by the rate they are made. Something else i like most about this is that we can not actually think of another method that can make these as cheap, as strong, and as recycleable and yet staying at the same production rate, clearly one of the most reputable production methods
glass bottles: my MOST favourable factor of this is that glass can be recycled infinite times, it makes this a truelly renewable resource. the way how the hot globs of glass are thrown through so quickly is amazing, although glass is a great RENEWABLE material, and it has its many positive properties when manufacturing, i can already tell that making plastic bottles would be significantly cheaper, i can tell first just by how hot the flobs get, that is alot of energy that needs to be used, resulting in a very high cost.
tetrapak: i have not known much about tetrapak as i never really had an interest in them. i always thought they were not ENTIRELY reusable, but when i found out that the entire tetrapak is made from recyclable materials i found interesting. It does look like a very costly method of manufacturing, i also found it od how there was more hands on labour intensive work rather than having the entire system automated. i always thought the layers get melted together but when i saw that they just get forced together by rollers i found significantly interesting. not my favourite production method but still very interesting
