The house is cleaned out with a front-end loader. The litter is loaded onto a covered conveyor then into a specially designed covered truck. No one would know it was litter in the truck. Everything has been sealed. Once at the plant, the truck unloads inside the closed building where a negative air system captures the air, preventing its escape to the outside environment.
Moisture captured in the air-treatment system is reused in the pelleting process.
Litter is loaded into feed hoppers with a front-end loader. Pasteurized litter passes into a hammer mill where it is reduced to the consistency of fine sand. Conveyors and elevators transport finished pellets to the finished product room. An in-ground conveyor system can then move the finished pellets to awaiting trucks or rail cars. Any dust or moisture generated during the process is reintroduced back into the pellet milling process - anything that enters the building even the dust and moisture is consumed in production.
