See www.retrologistik.com for processes regarding the return of chemicals and containers, or contact us there if you have further questions.

Waste Disposal

The solid or its solution is dissolved or diluted inlarge volume of water. Diluted acetic acid oracetone is then slowly added to this solutionin a well-ventilated area. Hydrogen generatedfrom decomposition of borohydride shouldbe carefully vented out. The pH is adjustedto 1. The solution is then allowed to stand forseveral hours. It is then neutralized to 7, andthe solution is then evaporated to dryness.The residue is then buried in a landfillsite approved for hazardous waste disposal.
