Talk:Plastic recycling

message: The section about the UK is simply not true. Almost every council provides either Kerbside collection or plastic bottle banks, and there is not always any idea of the source. "It all being sent to China" therefore can't be verified.
One problem, however, is the different types of plastic, many councils will not accept recyclable food containers to avoid confusuion. Almost all Supermarkets have plastic bag recycling points. Mojo 10:56, 27 August 2007 (UTC)

message: It seems very odd, and not good, that of the numbering system of 7 numbers, only numbers 1 and 2 are mentioned in this article. All the numbers should be mentioned, and what they are. Badagnani (talk) 19:01, 23 January 2008 (UTC)
replies: text: Unfortunately just because there is a recycling symbol with a number, doesn't mean that it can be recycled. PETE (1) bottles, HDPE (2) bottles, and stretchy plastics (like bags and wraps, often LDPE (4), or HDPE) are most commonly recycled. I found an article on PVC (3) recycling, which i added to the 'see also' section. Recently i found a website where you can mail in styrofoam, or E(xpanded)PS (6).  There are other types of PS and HDPE containers that cannot be recycled because of how it is chemically structured, even though they are technically the same 'type' of plastic. Also a site explaining why no one recycles PP (5) with a link at the bottom, How to Recycle Different Types of Plastics, which is also informative. (7) is just a catch-all. (more on the resin id codes)  Now if i only could have written that all into the article instead...Quickmythril (talk) 22:58, 23 January 2008 (UTC)

thread_title:  How do they reprocess the plastic? 

message: The article says Manufacturess of plastic food packaging and containers can voluntarily mark their products with the PIC, but according to Holt Chemestry (Florida edition), some countries/regions require manufacturers to label their products with the appropriate PIC. Also, PICs ca be found on all kinds of stuff, from prescription bottles to sheds, not just food containers. PCHS-NJROTC (Messages) 21:24, 2 January 2009 (UTC)

message: There is still an issue with overlap of content with the "process" section and "applications" section.  One solution might be to have a section for each type of plastic and then describe the processes used to recycle that plastic within that section.  A separate section could then include novel processes that are not yet widely utilized.  I would need to do more research before I can make that change to give each section significant content.

message: Is recycling actually worth it, or does it use more energy then making plastic from scratch? I would like see more about this debate since I find it quite difficult to make a conclusion.  —Preceding unsigned comment added by 139.222.224.70 (talk) 17:45, 7 February 2011 (UTC)

message: 'Typically a plastic is not recycled into the same type of plastic,'
A very odd thing to say. When plastic'c chopped, cleaned and melted it doesn't change into some other type of plastic!

Milly Zantow has passed away is Prairie du Sac, Wisconsin at 91.  You likely never heard of her. And yet she affected your life every day for decades.
You know the little triangle symbols on plastics, with the numbers (1-7) inside, that tell you how to recycle?  That's the "plastic identification code."  We all know it, and we think it's been there forever.  It hasn't.  It began in the late 1970s, and it all goes back to a very sweet lady, a neighbor of mine, Milly.  — Preceding unsigned comment added by 74.209.3.98 (talk) 02:19, 7 August 2014 (UTC)

thread_title: PYROLYSIS mention - Plastic-to-oil conversion

message: I want to know whether this can be efficient way of plastic recycling or not. Let me know your feedbacks about this.
1. chop the unsorting plastic wastes
2. shake it softly
3. then you can find the layers of materials caused by the density. This effect has name but i can't remember XD.
4. sorting complete!
5. Also you can use various kind of liquid that has specific density to sort the plastic wastes.
6. you can use water for washing wastes. is this too basic? XD

thread_title: New plastic sorting system

message: Can we mention the plastic waste sorting system by Imincorp (99% effective, using liquid with iron oxide particles), and Ioniqa's system to make new plastic from old plastic (the latter uses an ioniq liquid).

message: Wanted to capture a note here for @Project Osprey -- we are missing beneficial reuses that divert plastic from recycling wastestreams but need consistent quality (i.e. art from recycled plastic or Ecobricks). I am wondering if we need to work that into this article or the main article Plastic pollution? Sadads (talk) 12:56, 6 August 2021 (UTC)
replies: text: Maybe... though I'd worry about giving a WP:FALSEBALANCE. Are those things important, or just interesting? Do they reduce the need for new plastic to be produced, or do they just divert waste away from landfill. There's so much plastic to get rid of that I feel the focus needs to be on big solutions that can operate on the megaton scale. Plastic pollution feels bloated and unfocussed to me (although I am very fussy) but I think that plastic itself is in more need of attention. --Project Osprey (talk) 13:15, 6 August 2021 (UTC)

text: Also I'm pretty sure artwork and ecobricks count as reuse rather than recycling, as there's no reprocessing involved. --Project Osprey (talk) 16:02, 6 August 2021 (UTC)
thread_title:  Potentially missing an important part of reuse vs recycling 

message: There have been a number of recent articles and investigations (including a recent subpoena by the California state government on the matter against ExxonMobil) discussing the ineffectiveness of plastic recycling:

I feel that their exclusion undermines the neutral point of view (NPOV). ViperSnake151  Talk   15:20, 31 May 2022 (UTC)
replies: text: It's a fairly US-centric argument, driven in part it seems by a dip in plastic recycling during the Covid years. In the EU about a third of plastic is recycled at present, so its not entirely ineffective. What are you proposing exactly? --Project Osprey (talk) 15:37, 31 May 2022 (UTC)
replies: text: ViperSnake151, I agree that the exclusion of such sources undermines the NPOV of the article. As the COVID-19 lockdowns began, PBS Frontline released the documentary "Plastic Wars" in March 2020 that discussed the ineffectiveness of plastic recycling in the United States pre-COVID, and in May of last year, the Minderoo Foundation (one of the largest philanthropic organizations in Asia) published its Plastic Waste Makers Index report that ranked the countries of the world by per capita single-use plastic waste in 2019 (pp. 63–67). The United States ranked 9th with 53 kilograms per person while Singapore, Australia, Oman, the Netherlands, Belgium, Israel, Hong Kong, and Switzerland finished 1st through 8th respectively, and of the 27 EU members states, only Luxembourg and Malta did not make the top 100. So, I must disagree with your assertion, Project Osprey, that what ViperSnake151 is suggesting is a US-centric argument. -- CommonKnowledgeCreator (talk) 21:34, 22 November 2022 (UTC)

thread_title: Wiki Education assignment: Research Process and Methodology - FA22 - Sect 201 - Thu

message: I think it would be good if you added at least very brief info on synthetic biology-based processes under development (mostly). Such include for example this approach featured in 2022 in science:
A novel synthetic biology-based process for recycling of plastics mixtures is presented.
This is probably not relevant to recycling: Plastisphere#Degradation by microorganisms.
Moreover, there should also probably a bit more info on automated waste sorting and sortability/recyclability than section "#Sensor based separation" (see that article).
Info in Plastic pollution#Collection, recycling and reduction is missing here too.
