Emerging PFAS Pollutants at a Lithium Battery Recycling Plant.

The paper I'll briefly discuss in this post is this one: Nontarget Analysis of Legacy and Emerging PFAS in a Lithium-Ion Power Battery Recycling Park and Their Possible Toxicity Measured Using High-Throughput Phenotype Screening Zenghua Qi, Yutian Cao, Dan Li, Chenguang Wu, Kaihan Wu, Yuanyuan Song, Zeji Huang, Hemi Luan, Xiaojing Meng, Zhu Yang, and Zongwei Cai Environmental Science & Technology 2024 58 (32), 14530-14540.

For a long time around here and in many other places around the world, the absurd lie that energy storage is "green" has persisted with no amount of information being capable of dislodging the cultish faith that it is that, "green." The word "green" has become one of the most abused words in the English language. To my mind, a subject of my rather continuous harping, the most basic information - all that is a required - is that this is in fact a lie, the statement that storing energy is "green," is a law of physics, the second law of thermodynamics, which clearly shows that storing energy wastes energy. Since the production of industrial and consumer primary energy always has environmental effects, wasting energy increases these environmental effects. It makes things worse, not better.

The nonsensical belief that storing energy is "green," is exacerbated by other lies we tell ourselves. No matter how much we lie to each other and ourselves, however, to repeat my oft repeated chant, numbers don't lie.

A brief list of lies supporting the lie that storing energy is "green" and the numbers that expose these lies as lies, follows.

The world is not, despite the lie we tell ourselves, awash in so called "renewable energy," such that it overflows and therefore should be stored.

The numbers are here: 2023 World Energy Outlook published by the International Energy Agency (IEA), Table A.1a on Page 264.



The world is not awash in so called "renewable energy." So called "renewable energy" is trivial.

Another big lie is that so called "renewable energy" is "cheap." It is not. It is absurdly expensive given that it has proved to be a useless reactionary enterprise in addressing environmental catastrophe:

The amount of money spent on so called "renewable energy" since 2015 is 4.12 trillion dollars, compared to 377 billion dollars spent on nuclear energy, mostly to keep vapid cultists spouting fear and ignorance from destroying the valuable nuclear infrastructure.



IEA overview, Energy Investments.

The graphic is interactive at the link; one can calculate overall expenditures on what the IEA dubiously calls "clean energy."

A third lie supporting the lie that storing energy is "green" is that it has something to do with fighting climate change, but the reality that things are getting worse faster, despite these vast expenditures reveals this lie for what it is.

Update on the Disastrous 2024 CO2 Data Recorded at Mauna Loa

Some text I modify as required for my Mauna Loa CO2 Observatories updates for each in a series of posts I produce here:

There have been 2529 weekly data points such as that immediately above, recorded at the Mauna Loa CO2 Observatory which are available on the data pages of the website which compare the value with the same week of the previous year. The reading above, for week 28 of 2024, shows an increase of 4.50 ppm over week 28 pf the previous year, 2023. Among all such increases for weekly data, again, 2529 of them, compared with the same week of the previous year, this is the 11th highest ever recorded. It is one of only 29 readings to exceed an increase of 4.00 ppm, eight of which took place in the current year, four of which exceed increases of 5.00 ppm, three of which were in 2024. Of the top 50 week to week/year to year comparators 16 have taken place in the last 5 years of which 10 occurred in 2024, 39 in the last 10 years, and 45 in this century. Of the five readings from the 20th century, four occurred in 1998, when huge stretches of the Malaysian and Indonesian rainforests caught fire when slash and burn fires went out of control. These fires were set deliberately, designed to add palm oil plantations to satisfy the demand for "renewable" biodiesel for German cars and trucks as part of their "renewable energy portfolio." The only other reading from the 20th century to appear in the top 50 occurred in the week beginning August 21, 1988, which was 3.91 ppm higher than the same week of the previous year. For about ten years, until July of 1998, it was the highest reading ever recorded. It is now the 34rd highest.


Again, things are getting worse faster.

But the real indicator that the storage of energy is anything but green, relates to its mass intensity, and in particular, the toxicology associated with the production of this mass, and the fantasy that recycling this mass - which doesn't really happen on a scale approaching even 90% - is "green."

From the introductory text of the paper cited at the outset:

As the popularity of electric vehicles starts to soar, so does the volume of lithium-ion power batteries (LIPBs) that once powered those cars. In order to cope with the upcoming peak in the number of retired LIPBs, and the problems around the insufficient supply of the transition metals Co, Ni and Li and their rising prices in the battery manufacturing process, countries around the world are vigorously promoting and developing the lithium-ion power battery (LIPB) recycling industry. In 2022, China recycled 102,000 tons of spent LIPBs and this is expected to reach 570,000 tons in 2025. (1) The European Parliament and the Council stated mandatory requirements for the recovery of spent LIPBs in regulations issued on July 12, 2023. (2) At this stage, recovery of critical raw materials (in particular metals) through recycling has generated considerable economic and ecological value. At the same time, a number of environmental problems caused by the “recycling tide” of LIPBs have become increasingly prominent.

In the process of dismantling and recycling LIPBs, a variety of heavy metals from cathode materials, fluorine-containing electrolytes in the electrolyte, and toxic and harmful substances such as organic solvents will continue to be released into areas and the surrounding environment, which will cause serious harm to people’s health. (3,4) Although research and understanding of the pollution characteristics and health risks of pollutants in LIPB recycling sites are still very limited, it can be inferred that persistent (in)organic fluorinated chemicals are representative pollutants that should be focused on in recycling sites, based on LIPBs’ components, process flow and toxic effects. (5) Rensmo et al. demonstrated the possibility of perfluoroalkyl and polyfluoroalkyl substance (PFAS) formation and release during LIPB recycling with respect to battery composition and the recycling process (pyrometallurgy, hydrometallurgy), and highlighted the urgent need to investigate emissions of fluorinated substances during LIPB recycling. (6) PFAS have good thermal and chemical stability for reducing the surface tension of liquids and surfaces in the electrodes, binder, electrolyte (and additives), and separator. (7) During the recycling and disposal processes of LIPBs, PFAS may be released either directly or indirectly from the components. Notably, PFAS are easy to migrate and accumulate in different environmental media and organisms and can pose a threat to human health and ecosystem security. However, little information is known about the potential emission and occurrence of PFAS in LIPB recycling areas.

At present, the number of PFAS used in industrial production has exceeded 10,000 with various headgroups and properties. They may transform into one another in the environment, which poses significant difficulties for their detection when only depending on target analysis...


"Targeted Analysis" and "Nontargeted Analysis" are terms widely used in mass spectrometry, a scientific tool which has been the subject of astounding technical developments in the last three decades. Ultimately, at its core, my career is involved with this technology. "Targeted Analysis" is used when one wishes to quantitate a compound that one knows (or expects) to be present. "Nontargeted analysis" is used when one is searching for a plethora of compounds, some of which may not have been known to be present or even not known to exist. It also gives a looser idea of quantitation. The latter is obviously more complex than the first, and involves advanced (and very expensive) instrumentation.

Anyway, it looks like, from a toxicological standpoint, that magical "green" recycling of the much worshipped idea that batteries are "green" has some pretty profound toxicology associated with it.

The authors state that "a large LIPB recycling park located in the southeast of Guangdong Province, China, was selected as the study site."

They then exposed some worms to this mixture to study the biochemistry associated with these compounds.

I don't know about you, but when I read this paper, I mutter, "...so much for 'green'..."

By the way, one can see around here instances of people selling the big lie that hydrogen is "green" - I regard the "hydrogen is 'green'" myth as fossil fuel rebranding - pointing to instances of the flammability danger of batteries, which is, of course, real, but hardly common. (The smoke from burning batteries should be regarded as highly toxic.) There is even emotive discussions of cats being burned to death in a Tesla flameout in a garage. Speaking only for myself, I'm not sure the cats would have done better in a hydrogen explosion. Stored energy is inherently dangerous. It should be obvious, but somehow isn't, that gasoline is stored energy, the storage of hundreds of millions of years of the solar flux, and yes, gasoline is dangerous. Only a fool would say it isn't.

It is notable that hydrogen fuel cells are reliant on fluorine based organic chemistry.

I trust you will enjoy the holiday weekend.
