There’s good reason to dispose of tires properly. Fire speeds up natural processes which would occur more slowly under normal conditions. Superfund sites are the infamous result. Cradle to Cradle design is a laudable concept that does not apply when the materials being circulated are neither healthy nor safe. Tire manufacturing is toxic. New, used, and remanufactured products are the offspring of the toxic creation. To attempt a lifecycle development which incorporates direct human exposure to these toxins would seem ill-advised.
Caution and common sense thrown to wind, in this case, is an ill wind that blows nobody to good. Still, in the “greenest City in the US” where our Rec and Park department is rolling out a greener than green campaign and championing a “Children’s Outdoor Bill of Rights”, streets, preschool floors, swaths and fields, and soon, whole schoolyards have been and will be paved with tire crumb and plastic. The paper tape tells the tale. It’s encoded in the system in capital letters:
01000111 01010010 01000101 01000101 01000100
Here’s the rest of the CalRecycle grants reported for the City. Now you know why that used rubber is there in your neighborhood.
Some of the toxins found in artificial turf fields with SBR tire crumb infill are as follows:
acetone, aniline, arsenic, barium, benzene, benzothiazole, cadmium, chloroethane, chromium, cobalt, copper, halogenated flame retardants, isoprene, latex, lead, manganese, mercury, methyl ethyl ketone, methyl isobutyl ketone, naphthalene, nickel, phenol, polycyclic aromatic hydrocarbons, styrene – butadiene, toluene, and trichloroethylene.
