The department will use proxy food scraps generation factors and public and private databases available that provide information such as number of employees, college students, inmates, etc per location that equate to food scraps generation, to estimate the amount of food scraps generated from a source. Those calculations will be available on the department's website. If factors are not available or are not appropriate, the department will use other information, such as phone interviews and publicized research, to estimate food scraps generation. If more accurate site-specific data, such as weight receipts are available for a certain designated food scraps generator or type of generator (franchise stores, etc.), that data will be used by the department to estimate the amount of food scraps generated.
