Deffenbaugh Industries doesn't turn a deaf ear to its customers' waste management needs in the Plains and the Midwest. The company collects, transports, and disposes of commercial and residential waste in Kansas, Iowa, Missouri, and Nebraska. It also provides industrial waste services, quarrying services, the disposal of construction waste, and commercial and residential recycling. Deffenbaugh Industries' more than 700-acre Johnson County Landfill is the largest disposal facility in Kansas. The company's Johnny on the Spot division rents portable toilets.
