Impressions from this shallow dive:
- Some things are far better to recycle than others
- We should consider full costs (production and disposal) in whether to recycle or not, which probably involves some economic modifications on the present system.
- There are some tractable changes which could be implemented more widely, such as increasing waste collection services and increasing the spread of landfill technology.
- It seems like something which could benefit from much better international practice. It's possible this is something better suited to a large multilateral organisation's scope. In some ways EA is itself a large, multilateral organisation though, so maybe it’s not out of our scope.
Why don't EAs care more about what we leave behind? I have an underdeveloped wondering whether waste is a neglected cause area. I can think of impacts on equity, the long term, biosecurity and health, not to mention wild animal welfare.
Why waste?
Waste management and recycling programs are suboptimal in many countries, and where they are adequate (high income countries) they are still often ad hoc, with less desirable recyclables shifted to the global south to recycle. I’m Australian, we do this, and have a big issue with domestic recycling since China stopped accepting our recycling exports. International trade in waste products adds lots of miles to waste which could be managed in their countries of origin. Managing it better would have environmental, health and economic benefits, particularly in resource limited settings. I imagine one of the simplest improvements we could have made 50 years ago would be reducing plastic use. Wouldn’t it make sense to try and reverse this and other potential waste headaches of the future now?
Previous investigations
From reading EA Forum I can find the following summaries, which I have read and considered:
- Daniel Freidrich’s post on waste & resource scarcity argument as it relates to existential risk
- Sahron Ngaya’s effective E waste management in African countries
- Rob Wiblin’s discussion on waste. I broadly agree with the assessment, but think some arguments, e.g. about individuals reducing consumption and using reusable things are outdated.
Reasons why this might be justifiably not an EA priority (feedback welcomed).
- Not neglected enough - there’s a UN-brokered plastic pollution reduction treaty which might become legally binding in 2024. There are successful bans in 99 countries to reduce single use plastics.
- Perhaps it isn’t tractable enough, as environmental campaigns would have presumably seized upon the easy changes.
- Doesn’t represent enough of an X risk, due to similar arguments from climate change
Some ideas to address this issue (feedback welcomed)
- Better cost benefit assessment of the area to consider the full cost of metals and other very effectively recycled materials. For example, rare earth metals mining which is not only carbon intensive to refine, but has a very limited supply chain that is leaving countries very open to volatility (not just in an economic sense, but exposed to technological shocks if conflict arises).
- E-waste recycling (particularly salvaging working metal parts when the issue is, say a battery or the device is just outdated)
- Research into construction materials and their recycling, especially concrete, and whether subsidy/taxation is needed to change practices
- Policy work extending producer responsibility in places where it doesn’t exist yet (i.e. making producers pay for a portion of waste management)
- Expanding best-practice landfill technology (including methane capture) to places with large landfills
- Capture of wastewater during droughts using different technologi(see Bradshaw, J.L., Ashoori, N., Osorio, M., Luthy, R.G.’s 2019 article)
- Nuclear waste (I don’t know much about this at all)
Please tell me your thoughts, I am no expert in this area (at all). Thanks!
I'm also not a subject matter expert, but did spend a couple of years working with an academic spinoff monitoring illegal dumping, so here’s my two cents. Happy to discuss further with anyone interested in researching or acting in the sector, and may get around to writing a longer post if there's interest
Great comment, thank you for the info! It seems like there's many aspects to this issue, some which might be neglected and tractable and some which are really saturated already
Love the social enterprise idea
If you're especially motivated by environmental problems, I recommend reading the newly released book by Hannah Ritchie Not the End of the World (here's her TED talk as a trailer).
I'd like to correct something I mentioned in my post - I implied one reason I didn't find plastic pollution impactful, is that it just doesn't have an easy fix. I no longer think that's quite true - Hannah says it actually could be solved tomorrow, if the Western leaders decided to finance waste infrastructure in developing countries. Most of ocean plastic pollution comes from a handful of rivers in Asia. Since we have this kind of infrastructure in Europe and North America, our waste is only responsible for ~5 % of the ocean plastic (Our World in Data). Presumably, such infrastructure would also lay ground for reducing the harms coming from other waste.
I think there are two other reasons for the low attention to waste:
While I think one would do more good if they convinced a politician to target developmental aid at alleviating diseases and extreme poverty, than if they convinced them to run the project suggested by Hannah, perhaps given the bias I mentioned in point 2), it may be that politicians are more willing to provide funding for a project that would have the ambition to eradicate ocean plastic (constituting one of these ripple effects). So if you feel motivated to embark on a similar project, best of luck! :)
(The same potentially goes for the other 2 waste projects I've suggested - supporting biogas plants and improving e-waste monitoring/worker equipment)
Recently I've been hearing tires are a major cause of air pollution and AND ocean plastic pollution.
I think some changes in tire requirements could go a LONG way to improving these as I doubt much effort has gone into improving tire material's environmental impact yet.
https://www.theguardian.com/environment/2022/jul/25/tyre-dust-the-stealth-pollutant-becoming-a-huge-threat-to-ocean-life
https://www.thedrive.com/news/tire-dust-makes-up-the-majority-of-ocean-microplastics-study-finds
Looks like gov might be on the case, but perhaps we could get it moving wider and faster. "In the EU, the Euro 7 standards will regulate tire and brake emissions from 2025. In the U.S., the California EPA will require tire manufacturers to find an alternative chemical to 6PPD by 2024, to help reduce 6PPD-q entering the environment going forward. In turn, manufacturers are exploring everything from alternate tire compositions to special electrostatic methods to capture particulate output."
I've thought about this a little bit and then got stuck when it comes to figuring out where the big wins are and where the dead ends are.
In no particular order: Some metals are valuable. For this reason I don't think they are neglected but I also think the public doesn't know these metals should be recycled.
Recycling is almost certainly neglected because it is a public good that doesn't pay - these are pretty well always neglected.
Destroying things and making giant landfills feels bad and looks ugly but actually doesn't do as much damage as it feels like. The main reason that most waste campaigns give for more waste management is that it's destroying the earth. It's not. Getting an accurate picture of where the most damage occurs from bad waste management (perhaps polluted rivers in India? ghost nets left in the ocean?) is something very important and critical to the EA approach. As far as I know this hasn't been done yet. Not by EA and not by recycling orgs.
Recycling is tricky because there is the benefit of the materials (mostly estimated by their material value) but also the value of preventing more material from being gathered. (environmental damage) The material value is already pretty accurate I suspect. With one big caveat: As new forms of waste (for example plastic) appear, then it takes awhile for new forms of use (recycled plastic shoes? idk) to appear and value the material.
Some materials are so difficult to reuse that recycling them takes more energy and resources than simply disposing of them AND creating them anew. Those kinds of things ought to NOT be recycled! Maybe they should not created from the outset. Depends on how useful they are probably. Styrofoam is an example.
Environmental damage of creating more stuff is missing from the recycling economic math equation and is where potential important interventions would lie for society.
Toxic materials are a whole category that is very important and I know very little about. This is probably where the biggest improvements and most neglect is.
There are some cool new technologies to look into - a student I met was breeding bacteria to survive in highly metal contaminated environments to breakdown plastics and concentrate useful metals for waste management. Potentially a lot safer than human chemical processing.
Plastics are generally becoming more biodegradable. I'm not sure what body is pushing that to happen but it's a very good thing.
Furniture used to be a much bigger investment (like clothes were historically. People used to own 3-4 clothes and have them tailored. hard for us to imagine), but changing technology, culture, and mobility is turning furniture into a disposible resource. Potentially eventually almost as disposible as clothes. This seems like a big shift that recycling and reuse should anticipate and adapt to. Encouraging standards could go a long way to making furniture more valuable materials and increase the post-first-use value for both the purchaser, the recycler, and society.
Thanks! And totally agree! Many of these points are similar to the thoughts I've been having since looking into this. Addressing highly toxic or very poorly managed waste sectors makes a lot of sense. Would be interested to know more about the plastic eating bacteria
I remembered incorrectly - it was not the plastics, but the rare earths that they were recycling. Tanzeena Hussain was the graduate student working on it and having success getting bacteria to survive in increasingly toxic environments. She was crushing up old electronics to feed the bacteria - pretty on the nose.
It was in Elizabeth Skovran's lab at San Jose State University. This is the only write up I can find on it: https://blogs.sjsu.edu/newsroom/2023/taking-bio-recycling-to-the-next-level/
It looks like they are having enough success to file for a patent and investigate if this could eventually be a viable business too. But speeding this up at such early stages could be hugely beneficial to reducing mining and improving human health damaged by rare metal recovery.
Container-deposit legislation seems like existing policy to investigate strengthening:
https://slate.com/technology/2013/08/bottle-deposit-should-keep-up-with-inflation-time-to-raise-fee-from-a-nickel-to-30-cents.html
Do you mean it seems like it is existing policy or that strengthening it should be investigated?
