“Pyrolysis” means “pyrolysis” as defined in RSA 149-M:4, XVIII-a, namely “a manufacturing process through which post-use polymers are heated in the absence of oxygen, sometimes in the presence of catalysts, until thermally decomposed and are then cooled and condensed. The resulting chemicals, when separated from wastes, can provide raw materials for the production of plastics, lubricants, waxes, and other industrially useful chemicals.”
