BioSpan Technologies, Inc. is committed to providing cost effective and environmentally friendly solutions in the fields of paving, biodecontamination, and environmental recovery and resource utilization of solid waste.

FSR-4450™ is the first non-toxic, biodegradable, environmentally friendly expanded polystyrene foam remover available to the road construction industry. It is formulated to effectively dissolve styrofoam (EPS) in all temperatures. It works fast, and should be applied by spraying the foam with the solution. FSR-4450 works on all styrofoam formulations. It is made from materials that are non-toxic and will not harm the environment.

It replaces the use of petroleum based foam removers which harm the environment and are banned from use for this application. FSR-4450 is also an excellent EPS and extruded polystyrene foam remover for boat dock floatation foam, and foundation underlayment materials such as Geofoam.
