Although waste characterization data is intended for solid waste planning, it may be helpful to anyone curious about the traits of the solid waste stream. To determine how much of a certain substance is present in their waste stream, local government planners, haulers, and recyclers can utilize the waste characterization tools on this website. A significant portion of CalRecycle’s waste characterization data aids businesses in understanding what makes up their waste streams, which is the first step in coming up with solutions to minimize trash and lower disposal costs.
