Consisting of primarily soil, wood, concrete, gypsum and other miscellaneous material particles, fines have received increased scrutiny due to their association with hydrogen sulfide (H2S)—a colorless gas that generates toxic emissions, odors and a risk for fires even in low concentrations.

In addition to H2S, concerns over toxic compounds polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) have left recyclers stumped on how to utilize fines in a safe and environmentally friendly way.
