We have 60 litres of organic solvents as HPLC waste collected in the solvent bottles, how can these be discarded?
It is better to discard the waste as these days, HPLC solvents are cheaper in price and also we require high purity solvents. So please go through the following article:
LCA approach to the analysis of solvent waste issues in the pharmaceutical
industry (Green Chem., 2010, 12, 1826–1834. (DOI: 10.1039/c003666h))
What solvents? There ought to be a hazardous waste disposal company that will take it (for a price). The university probably has a contract with someone already, so discuss with your department head or safety officer. Some institutions will use flammable organic solvents for co-generation, which is why I asked what solvents?
Its a mixture of IPA:Hexane with eluted epoxides and diols analyzed on HPLC @Jack Silver.
That mixture is "burnable" We have a proper disposal company that picks up our waste; it is burned and used for making bricks (heating the oven).
