Plastic Waste
For the past few days news on the plastic eating enzymes been offered as the solution for some of our plastic waste. Is anyone old enough to remember the BBC Doomwatch program where aircraft were falling out of the sky because the plastic in them was being recycled this way? -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

It is an enzyme that can digest PET discovered by researchers at Kyoto. https://www.sciencealert.com/new-pla...ing-revolution Several biological polymers also exist that degrade in the environment but they are nowhere near as good as engineering plastics. OK for golf tees and similar small objects that often get lost though. Never been particularly commercially successful an ICI/Zeneca invention sold to Monsanto and then changed hands a couple more times since. http://www.bioplastic-product.com/biopol/ Is anyone old enough to remember the BBC Doomwatch program where aircraft were falling out of the sky because the plastic in them was being recycled this way? Yes. Plastic components turning to grey goo. ISTR Prince Charles has wittered on about it too. http://news.bbc.co.uk/1/hi/uk/3883749.stm -- Regards, Martin Brown |

I am pretty sure they did books of some of the more popular episodes, and I had that one at some stage. Not very good, as is mostly the case with converted scripts. I just had a look, and I don't seem to have it any more. -- My posts are my copyright and if @diy_forums or Home Owners' Hub wish to copy them they can pay me £1 a message.

Yes despite the hammy acting very scary.

On the subject of plastic waste, many of the fields around here are covered in polythene sheet ATM. From a distance they look like sheets of water, until you realise they're not horizontal. They are there to cover rows of potatoes, to warm the soil and bring them on early, to compete with 'new' potatoes from Egypt and Malta. After harvesting the spuds in the Summer, the poly sheet is now dirty with soil etc. and the farmer has to pay for it to be recycled, as it has to be washed, and that's expensive. It's usually just bundled up and dumped in the corner of a field, sometimes set fire to on a still Summer's evening at the weekend by "bloody kids" perchance? -- Jim K ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

It all depends on whether the substance left after its been eaten is of any
use or less harmful. Brian -- ----- - This newsgroup posting comes to you directly from... The Sofa of Brian Gaff... Blind user, so no pictures please! "alan_m" wrote in message ...

It was Prince Charles who was to blame, but Doomwatch certainly did not
help. Brian -- ----- - This newsgroup posting comes to you directly from... The Sofa of Brian Gaff... Blind user, so no pictures please!

If I recall it was accidental in the doomwatch story. If ever you develop
something like that you need to also make sure you can destroy your creation in case it escapes out of the confines of its intended use case. I can see this increasingly being deployed as a weapon.

Brian Left to its own devices the organism will metabolise the plastic back to CO2 and H2O but by stealing its enzyme the researchers got something approximating the monomers/components that when polymerised form PET. How bad you think mobile low MW phthalates are depends a bit on gender. https://en.wikipedia.org/wiki/Xenoestrogen It isn't the only way to do it see 10.3 in https://en.wikipedia.org/wiki/Polyet..._terephthalate -- Regards, Martin Brown |

We had some Tesco ones that did the same. IIRC quite a few decades ago, the whole business of plastic bags littering the countryside was a popular topic, because they weren't breaking down. Then some chap came up with the idea of incorporating starch granules into the plastic, which would degrade in sunlight or something, and the plastic would fairly rapidly disintegrate into smaller and smaller pieces, so would no longer be visually offensive littering roadsides etc. I wonder if that process is still used, or if they have another way of getting the bags to fall to pieces. I think those were an oxi-degradable plastic. I remember putting some Christmas tree decorations in one and storing it in the loft only to find that it had fallen to pieces by next Christmas. Certainly didnt need light to trigger the process. There are photo-degradable plastics but they just fragment and arent really a solution to plastic pollution. Tim -- Please don't feed the trolls |
