Pouring solvents down the drain may be an easy way to dispose of them, but this act can be a costly mistake for your business. Many solvents are considered hazardous waste, and with that designation comes a host of regulations you must follow for proper disposal. What many companies may not realize, however, is that solvent waste still plays a valuable role in industry even when they are spent or no longer can be used. In fact, solvent waste plays a critical role in the circular economy, a viable alternative that manufacturers are exploring as they look for ways to save costs and improve their sustainability.
