Business method to manage the non-waste handling elements of solid waste management

An improved method of communication, control and command for patron functional services for solid waste management districts to minimize solid waste and solid waste management costs and maximize recycling and convenience. The publicly accessible solid waste disposal site is to be equipped with area lighting, video camera(s), a means for patrons to communicate identity and service data and a means to transmit and receive video and other data to and from remote data management facilities. The patron is required to identify his or her self each time he or she utilizes a public solid waste disposal facility. Commercial haulers are required to identify themselves and the source of the waste and provide a volume estimate. The camera(s) verify compliance. The remote data management facilities communicate with patrons, maintain records, calculate billings and monitor public solid waste deposit facility video camera(s) for security, maintenance needs and compliance verification. Two operational elements predominate: The patron is identified at the solid waste deposit facility and bill reductions are granted for demonstrated waste minimization, both of which may be accomplished in numerous ways. Identifying the patron demonstrates the patron's physical presence at the solid waste disposal facility. In that the patron is required to be present at the solid waste disposal facility periodically, and in that billing is not relative to discarded waste volume, there is no advantage to illegal roadside dumping. Waste minimization is measured by demonstrated proactive conservation efforts rather than by discarded waste volumes. This allows a totally automated solid waste disposal facility.
