Disposal of ECOSURF EH-40:
Although the ECOSURF EH-40 are considered readily biodegradable (>60 percent biodegradation within 28 days per OECD 301F) TERGITOL ECO-20 has been determined that for unused & contaminated product, the preferred options for disposal include sending to a licensed, permitted incinerator or other thermal destruction device. 
Architectural coating formulation processes that operate under zero-discharge of wastewater should not trigger the SNUR conditions but each user should assess their operations to assure compliance. 

The SNUR limits release to water to no greater than 14 ppb as calculated after wastewater treatment.
Dispose in accordance with all local, state (provincial) and federal regulations. 

Empty containers may contain hazardous residues. 
ECOSURF EH-40 and its container must be disposed in a safe and legal manner.
