The above missed out the arrangement as was in the early link/post where a large bucket has a smaller black bucket raised inside it the larger bucket/container has a transparent top and is sat in a shallow tray of cold water.
Please keep in mind, as stated previously, we are unable to give exact disposal instructions as legal requirement vary from place to place. I hope this article helps!

sand tz : en général, les déchetteries municipales ont un dépôt spécial pour les produits chimiques et toxiques. Il suffit simplement de mettre ton IPA dans une bouteille fermée hermétiquement et d’inscrire bien gros ce qu’il y a dessus. Je précise toujours quand je dépose mon alcool ce que c’est aux personnes sur place vu que c’est hautement inflammable.
