Solvent recycling is an environmentally preferred alternative to other means of hazardous and non hazardous waste disposal whenever feasible. Reclaimed chemicals and solvents take many forms—from hydrofluoric acid, to solvents and paint additives— and can benefit a range of industries, including automotive, pharmaceutical, and plastics manufacturing.
TIER uses state-of-the-art equipment and superior distillation processes to separate solvents from pigments, resins, and polymers. The resulting clean solvents can then be made available to a range of customers for reuse at a fraction of the cost of virgin materials.
Hydrofluoric Acid Re-concentration
TIER employs a sealed production system to deliver hydrofluoric acid (HF) in 10%-70% pure concentrations, as well as for proprietary blends. Our highly trained chemists and technicians are committed to the safe storage, processing and packaging of HF. Our state-of-the-art processing equipment enables hands-off blending, packaging, re-concentrating, and dilution. Some common uses of Hydrofluoric Acid include:
- Glass and metal etching
- Oil refining processes including production of high octane fuels
- Production of plastics
- Fluorescent light bulbs
- Production of refrigerants
As your HF supplier, we help manage and meet your needs via an automated process. By maintaining and updating your purchasing profile, we can track the materials you need in the proper concentrations and quantity you require. Our in-stock program can be adjusted as your needs evolve to ensure timely delivery of the products you need when your business demands them.
At TIER, we are committed to continuously improving our efforts to reduce the amount of waste released into the environment. Solvent recycling is one of the ways in which we do this, whether returned to our customers or made available to others. TIER’s reclaimed solvents are up to 99.9% pure, and are available at a fraction of the cost of virgin material. Several H.E.S. Specialty Blends of reclaimed solvents are also in stock and suitable for many applications including parts cleaners, and wash solvents. Reclaimed solvents that are generally available include:
- Methyl Ethyl Ketone (MEK)
- Ethyl Acetate
- n-Butyl Acetate
- High-Aromatic Blend
- n Methyl 2 Pyrrolidone
- Paint and Lacquer wash blend
- Line Flush Blends
In an effort to continually expand recycling of hazardous wastes and thereby reduce the reliance on incineration and landfill, TIER has developed a usable byproduct from the solvent distillation process. Solvent recycling through fractionation naturally creates still bottoms, which would ordinarily be sent to a hazardous waste incinerator for disposal. At TIER, we have successfully blended this mixture of still bottoms into additives to be used in specialty paints. By reclaiming the waste solvent and producing the byproduct from the still bottoms, the entire waste material is recycled—and the need for incineration is eliminated. TIER continues to evaluate this mixture of still bottoms for additional uses in commercial products.
