Solder paste tube disposal

Solder paste tube disposal | 27 August, 1999

Recently, our solder dross reclaimer refused to take our used solder paste tubes. He said the small percent of paste remaining in the tube is now considered hazardous waste. I'm interested in advice on how others are disposing of this "hazardous waste". Thanks in advance!

We have no problem with our tubes, the vendor (Alpha Metals) has them qualified under the classification of 'recyclable materials' as long as they are kept separate from any other solder bearing reclaim.

Thanks in advance! | We treat all our material that has lead on/in it as Hazardous Waste, that includes kimwipes that have cleaned stencils and our mylar used for stencil alignment -- ANYTHING with lead. We have properly labeled Harzardous Waste containers and we use a properly certified disposal company to come pick it up, with all the proper manifests, paperwork and yada yada yada with the EPA, et. al. Them's the rules... Scott

Bloody Hell! DROSS is hazardous waste! And probably much more hazardous than solder-paste smears in a used pot. It would seem obvious that your reclaimer is not with it and is prevaricating because he does not want your plastic because he cannot make a profit from it.

If all else fails, then your best solution is to wash the pots/syringes/cartrdiges/tubes/whatever out with e.g. the cheapest alcohol you can lay your hands on, until they are visibly free of grey smears and pour the dirty alcohol onto your dross (in closed cans). The remaining plastic can then be sent for recycling. Now for the $64,000 one: how do you clean your screens/stencils? What do you do with the resultant powder? Can you not put your pots etc. into the screen/stencil cleaner?
