Is fiberglass a carcinogen?
It also has some worried that the fibers from fiberglass are just as dangerous as asbestos -- it's sometimes referred to negatively as "man-made asbestos" or the asbestos of the 20th century. But while early research on rats in the 1970s stated that "fibrous glass of small diameter is a potent carcinogen," more modern research isn’t as sweeping in its findings [source: Montague ]. The American Conference of Governmental Industrial Hygienists, on the other hand, claims fiberglass is "Not Classifiable as a Human Carcinogen," meaning there isn't even data to say whether or not it causes cancer in people [source: Yeshiva University ]. The U.S. National Toxicology Program issued its 13th Report on Carcinogens in fall of 2014, and while its entry on Certain Glass Wool Fibers (Inhalable) states that they are “reasonably anticipated to be human carcinogens,” it also goes on to say that there is so much variation in production that full assessments must be made on a case-by-case basis [source: NTP ].

The polyol, which is mixed with isocyanate to form polyurethane is, in general, a relatively harmless alcohol compound and is primarily added for greenwashing PR reasons as it can be made with soy and other natural oils.
Is spray foam recyclable?
Currently, not really no. I’m sure someone somewhere has come up with a creative use for old bits of spray foam, but for the most part it will be heading to a landfill at the end of its life. Wood studs are recyclable, plywood is recyclable, rigid foam insulation boards like EPS are recyclable and even reusable, but anything with spray foam stuck to it is in all likelihood going to the dump. That means any wood, concrete or plastics that it is adhered to that could have been useful will fill up a landfill.
What is isocyanate made of?
Isocyanate often comes from methylene diphenyl diisocyanate (MDI), and the manufacturing of MDI includes such ingredients as benzene, chlorine compounds and formaldehyde.
