JAMAK Fabrication, Inc.
We use methanol as a carrier for an adhesive product. Parts are dipped into the solution and when the methanol flashes off, the adhesive is left on the part. The process as originally designed required the parts to be dipped hanging from one end and the entire part had to be covered with the methanol/adhesive solution. The tank originally held 55 gallons of methanol and 9 gallons of the adhesive.
We modified the dip tank and the parts orientation. We placed an insert in the tank to reduce the total volume of the methanol/adhesive mixture from 64 gallons to 10 gallons, and placed the parts in the tank flat. This resulted in an 85% reduction in hazardous waste. This redesign also reduced the charge cost from $1,620 ($28,183 per year in 2008) to $243 ($6,733 per year) with an annual cost savings of $20,750.

This equipment modification allowed the facility to change its hazardous waste generator type from small quantity generator (SQG) to conditionally-exempt small quantity generator (CESQG).
