- "Commercial greens are often made with pigment green 7, which contains chlorine and can’t be recycled or composted safely." ?

Uhhh what's the problem with chlorine? Chlorine kills living cells, bad for any living organism in water, most often damaging fish's sensitive gills as well as the skin that covers their entire bodies. Definitely bad for compost as it kills all the microbes and little fun guys doing the work.

  Elemental chlorine maybe, but there’s none of that in green 7.

    I agree. Probably the confusion is caused by the common name of the additive for fish tanks "Dechlorinator". But the "Dechlorinator" does not remove Chlorine atoms from the water. It only transform the NaClO (bleach [1]) into NaCl (table salt[1]). It "steals" the oxygen and binds it to another molecule. [1] ignoring a few technical details.

  "However, the presence of chlorine in an organic compound does not ensure toxicity. Some organochlorides are considered safe enough for consumption in foods and medicines. For example, peas and broad beans contain the natural chlorinated plant hormone 4-chloroindole-3-acetic acid (4-Cl-IAA);[13][14] and the sweetener sucralose (Splenda) is widely used in diet products. As of 2004, at least 165 organochlorides had been approved worldwide for use as pharmaceutical drugs, including the natural antibiotic vancomycin, the antihistamine loratadine (Claritin), the antidepressant sertraline (Zoloft), the anti-epileptic lamotrigine (Lamictal), and the inhalation anesthetic isoflurane.[15]" https://en.wikipedia.org/wiki/Organochlorine_chemistry#Toxicity https://en.wikipedia.org/wiki/Organochlorine_chemistry#Toxic... incineration might be a bad idea but composting might be fine if we are talking about https://en.wikipedia.org/wiki/Phthalocyanine_Green_G https://en.wikipedia.org/wiki/Phthalocyanine_Green_G it's apparently nontoxic enough to use as a tattoo ink so I wouldn't worry about it this is just another witch-burner who wants to destroy anything they don't understand out of fear

    I agree, except for the last sentence. My guess is that it's someone confused by the misleading name of the fish tanks additives. (More details in my reply to the sibling comment.)

      could be, but i meant the scaremongering in the article elemental chlorine legitimately is pretty toxic

  You're referring to elemental chlorine. Your food almost certainly has a compound which contains chlorine too, and makes it taste better.
  - adrian_b 4y ago
    Not only it makes the food taste better, but if a human or any other multicellular animal does not ingest daily enough chlorine in chloride form a quick death is certain. Chlorine, as chloride, is absolutely necessary for the control of the pH and of the osmotic pressure of the extracellular water contained in the body of animals. Moreover, chlorine, as chloride, is necessary for the digestion of the food and for killing most of the microbes ingested together with the food (by making acidic the interior of the stomach). The plants need much less chlorine than the animals, but nonetheless a very small amount of chlorine is absolutely necessary for photosynthesis, being bound in the structure of the Photosystem II, which splits the water, releasing free dioxygen.

    I don't think you need to be water soluble to have impact on aquatic environments; take for example microplastics?

Just by intuition, highly halogenated polyaromatic compounds such as this seem like they might degrade into terrible things - Compare to dioxins. Definitely would not want to burn them at the very least
