When dealing with waste solvent, it’s important to know the distinction between the types of organic waste solvents, and how solvent recyclers can increase their shelf life. According to the EPA, a waste solvent typically falls into four waste stream categories:
- Non-Halogenated Solvent Waste: This is the most common waste stream, consisting of solvents such as acetone, ethanol, methanol, ether, hexanes, ethyl acetate, and toluene.
- Halogenated Solvent Waste: Solvent waste that contains, either in total or as a mixture, halogenated solvents such as chloroform, dichloromethane (methylene chloride)
- Heavy Metals Solvent Waste: Solvent waste that contains quantities of heavy metals, such as arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver
- Paint Solvent and Residue: Solvent waste resulting from using oil-based paints and thinners, including amounts of oil-based paint residue
Waste Solvent Classifications
Some waste solvents are incompatible with one another, so it’s necessary to separate these categorically.
This segregation is also necessary because halogenated substances require more extensive treatment in order to minimize environmental impact during solvent waste handling. The following table indicates the category for each individual solvent waste:
Halogenated and Non-halogenated Waste Solvent Recyclers
At Solvent Recycling Systems, we take halogenated and non-halogenated waste solvent that is no longer useful due to a contamination and regenerate it through on-site solvent recycling. We use IoT-enabled distillation units that are suitable for all types of processing requirements, meaning our customers can:
- Respond to critical warning alerts only
- Improve routing and shipment efficiency
- Increase customer satisfaction and uptime
- Adhere to corporate disposal and compliance regulations
Furthermore, by applying predictive analytics to solvent recycling, SRS can significantly reduce labor costs associated with manual tank inspection, and raise productivity for facilities of all sizes. This means that any business model can take advantage of solvent recycling without the costly burden of managing the still in-house.
