Obsoleteness VI - Plastic

There was a time when human products were ecological and sustainable, or at least much more natural before the invention of plastic. Ropes and nets were out of hemp, pots and kitchenware were out of clay, iron or copper, or even wood or tightly woven straw, clothes were made out of natural material like linen, hemp, wool or cotton; toothbrushes and combs, too, bottles were made of gourds, glass or clay, or later ceramics, wicker baskets were made out of willow rods, and grocery bags were out of hemp ropes. When it became worn out it could have decomposed in or on the soil. We should not romanticize it as the Romans were poisoned by lead that the enamel of their kitchenware contained (or maybe just slaves were fed up with them and did it on purpose). Also the blacksmiths became sick due to the vapor of the molten ore. And, I guess, others got other ailments. Now, we are surrounded by plastic wherever we go – it's lighter and cheaper. But is it cheaper on the long run? Now, humans produce almost 20,000 plastic bottles per day and across the world in 2016 480 bn plastic drinking bottles were sold worldwide. And, these are just plastic bottles. Between 5m and 13m tones of plastic leaks into the oceans, and is consumed by marine animals and people who eat seafood, ingest up to 11,000 tiny pieces of plastic every year, tells us this article. More data can be obtained here and here is a more recent study about synthetic polymer contamination in global drinking water.  Those articles tell that plastic is produced at higher rate than it could be recycled (now ca. 10% is recycled), even though quite some initiatives have been established to depolymerize used plastic back into gasoline (but first it has to be collected and delivered to such a factory), to use it as construction material in form of bricks or building blocks (will it be hazardless to live in?), to harden the asphalt, to use as plates against flooding. I don’t want to moralize, but we should reconsider what we do on this planet. We extract crude oil from the Earth, produce some products and throw it all around the planet where they poison other creatures and eventually us. What we do to the planet and our fellow creatures we do to ourselves.

Sort:  

Depolymerization of plastic for reuse or use as gasoline is energetically not sustainable hence not only not ecologically but also not economocially. PET for example can be recylced (and already is to a rather high extend in Middle Europe, of roughly 40-60%) without breaking up the whole chemical structural network.
Other plastics can not be reused/recycled in such a way, due to the very properties they were initially designed to have (high mechanical or thermical resistance). Those plastics can only be energetically recycled, what means that they have to be burned. If this is done i a proper way (depending on the specific plastic) it is just the same like burning wood. The energetical output and the released gases are pretty much comparable.
...Just adding to your depolymerize-into-gasoline-statement. ;)

I guess they must have pretty thick filters if they are burning plastic. And as usual, if the fine is cheaper than the less poisonous and probably more ecological solution, then the businesses will choose a fine, or some cheaper solution no matter of the consequences for environment. That's the way it is. And, I don't expect it to change it so soon.

Take PE (Polyethylen). It is built up out of Carbon and Hydrogen. Hence does even has less problematic Elements than Wood (N and S will form gaseous oxides). Burning PE (at appropriate elevated temperatures) will eventually lead to CO2 and H2O only.
Placing a fine on such a process to drive recycling towards 'depolymerization to gasoline' would be irrational and a bigger ecological burden than the other way round. I guess I have to do a more deep diving article on this topic to show the basic calculation behind. :-)

I didn't write this to propose or promote any fines, but to show that the impact of decomposing plastic is already shown on humans - that is on water and seafood.
When washing fleece it tiny fibers fall out and enter the sewage. Besides, I just wanted to show that there are other possibilities, too. The main purpost of my post was to show that we all use plastic and that it is already a very similar problem to humans as it is to animals. What we do to them, we do to us. Mass production causes this and mass consumtion, and the invention of plastic initially. Have humans ever invetened anything where the decompostion of waste (when a product comes to this stage) is included into the invention&production&consumption. So, what do they do with the CO2 and H2O from the incineration process? Do they sell it or just release it?

The main problem is inproper disposal/degradation and in some cases inproper use. Neither invention (as an intellectual process primarily) nor modern production are dangerous or harmful.
What a question... CO2 and H2O are released. Like IT is also done if you fire any 'natural' called energy carriers like wood.

First, you actually write here to earn for your own comments. Second, you try to tell me that nuclear bomb is harmless (sorry I remember quite good how Chernobyl felt). Third, CO2 is released and we pay carbon dioxide taxes. Yay!

Don't mix up knowledge/IP/Inventions and their actual way of usage. ;-)

Good post

Back then, plastics were considered the pinnacle of human innovation. By mixing polymers, humans have created a material that couldn't be seen anywhere else. Alas, humans aren't really equipped for those sort of innovation at the time and the result was a catastophic mess. A hundred years from now, many of the plastic waste would still clog waterways. I'm glad that recent innovation surrounding biodegradable plastics have been embraced. Let's hope that plastic becomes obsolete before humanity does.

It's a hope yes, so I hopefully hope that we won't become plastified before plastic gets obsolete. ... and that they don't produce some even more harmful material.

Suddenly people are talking about this and pondering change.

About bloody time eh!

Man is a foolish animal.

:(

Succinct and informative post ~ thanks.
