• Is waste solvent recovery safe?
• Will the recycled solvent meet or exceed virgin purchased specifications?
• What permitting is required to operate a CBG waste solvent recovery system?
• Will the leftover material after the recycling process be considered hazardous waste?
• Is there any special expertise required to operate the recovery system?
• How much operator time is needed for waste solvent recovery?
• Are there equipment or electrical drawings/schematics available?
• What is the expected life span of a CBG waste solvent recovery system?

• Is waste solvent recovery safe?
  Yes! All CBG solvent recycling systems are ETL listed to UL 61010 and UL 2208 for use in non-hazardous environments. Automatic shutdown sensors and pressure relief valves are a standard on CBG systems. For industrial and manufacturing customers who want to recycle but need to operate a recycler in a hazardous setting, the unit can be constructed to Class 1 Division 1 standards.
• Will the recycled solvent meet or exceed virgin purchased specifications?
  Yes, our fractional distillation units will produce recycled solvent that meets or exceeds original specifications, as long as the system is operated correctly and according to the provided user's manual. Our simple distillation units also will produce a high purity recycled solvent, but such purities will vary depending on the waste contaminants.
• What permitting is required to operate a CBG waste solvent recovery system?
  No special or additional permitting is required under Federal EPA laws. The recycling process itself is exempt from RCRA regulations found under 40#CFR 261.4(a)(8). However, the storage of hazardous waste is still regulated in the same manner.
• Will the leftover material after the recycling process be considered hazardous waste?
  Waste solvent recovery results in just two products: the recovered solvent and the remaining waste. You are not creating a new product, nor are you treating the solvent. You are simply separating existing components. The remaining waste will still be considered hazardous waste.
• Is there any special expertise required to operate the recovery system?
  No. A relatively untrained person can easily operate the recycler. CBG offers the option for onsite installation and training for all who wish to receive it.
• How much operator time is needed for waste solvent recovery?
  You can expect to spend about 15 minutes per day, including time for loading the waste solvent into the recovery unit, closing the lid and hitting the start button. At this point. the operator can "walk away" -- the unit operates automatically and will monitor itself through the shut down phase.
• Are there equipment or electrical drawings/schematics available?
  Yes. Simply contact us and we will provide them for you.
• What is the expected life span of a CBG waste solvent recovery system?
  The expected life span of the recycling system is at least seven years - there are many CBG waste solvent recovery systems still in use after 10 years or more. All CBG Recycling systems are built and constructed "durable". The processing tanks are custom manufactured of heavy gauge stainless steel. The units all incorporate high-quality sheet metal cabinetry, with a superior powder-coated finish to resist corrosion and rusting.
