Maximize equipment dedication. Use dedicated vacuum systems to optimize reuse of contaminated dusts. Use pumps and piping to transfer liquids to minimize potential for accidental spillage. Recycling and Resource Recovery Reuse spent solvent and wastewater from equipment decontamination as makeup in subsequent formulations. This allows sale of drums to scrap dealers as a non-hazardous waste.
Return drums to pesticide supplier for refilling with the same pesticide.
Ship unrinsed drums to an off-site drum reconditioner. Segregate the various process waste streams. Using specialized treatment systems can be more cost effective than utilizing a large complex treatment system for combined waste streams. Treatment Treatment of pesticide-contaminated wastewater can allow reuse of the wastewater in formulating and other associated operations, particularly when high purity water is not required. Activated carbon adsorption.
