We spray paint large steel beams in a dedicated building of which dust accumalates.  At present we dispose of this dust in IBC's but perhaps we don't need to and can just empty it into our general skip.  Does anyone have advise on disposal of paint dust?  We deal with empty cans, left over paint as a separate issue.  All risk assessments and control measures are dealt with - I am just concerned with finding out about the dust.  Thanks.

You really need to discuss this with your waste handler as it is their transfer station and disposal point which will ultimately "set the rules"

We had a system of disposing of bulk bagged dust from an LEV that involved placing the bag in the skip however on changing provider the new site could not handle tipping the skip without ripping the bag and sending up plumes of dust. We had to change to much more expensive practices well beyond the cost saving that switching provider was meant to have secured.

What sort of paint exactly, 2-part epoxy? what you need to do is work out the correct EWC code for what you have, by deciding what you have left once the paint has fully cured and any VOC’s have evaporated.

If it contains no hazardous substances once dry it will be one code (perhaps 20 01 28) but if it does then it may be 20 01 27*. Now you should not mix wastes, but if this dust is already mixed with other dusts and it is non hazardous then you are possibly ok. If it is hazardous still then separate and specific EWC code. What EWC is used at the moment ( is it the same as for the wet paint – See SDS to check against current waste note for the IBC’s). Does it take a long time to fill the IBC or a long time ie do you only generate small amounts

Once your paint on your steelwork is dry one would assume it is no longer hazardous once Fully cured, so why should the dust be.
