                 36.2 Waste Management Goals


                 and Opportunities



                 The majority of solid waste generated by this sector is paper, biohazards, food, plas-
                 tics, and cardboard. Table 36.1 displays the composition breakdown based on survey
                 results.
                    As shown in the table, the recycling rate for this sector is approximately 19 percent.
                 As derived from the solid waste evaluation model discussed in Chap. 12, the equation
                 that estimates the annual waste generation per year per employee for this sector can
                 be calculated from the following:


                     Tons of solid waste generated per year = 0.98 × number of employees + 21.43





                 36.3 Constraints and Considerations



                 In terms of solid waste management and minimization for health-care facilities, the
                 five key constraints and considerations are


                 1 Available space to store and stage materials (interior and exterior)—This includes
                    space within the facility and dock space for storage. The numerous deliveries that
