Waste materials are emptied into the Qube Trailer using an opening at the top. The blade moves the material into the body and at the end of the cycle, the opening is sealed. The variables of airborne debris and open containers are a moot point.
This differs vastly from the process of emptying containers where waste materials from containers free fall while emptying into the front loader. Debris can become airborne. Also, there are times when the lids of the containers are left open and the container then becomes a source for birds and rodents to feed and move about uncontrolled.
