Eureka Recycling Composition Analysis Methodology Eureka Recycling collects materials in a single sort collection system with all paper, cardboard, metal and plastic, steel, aluminum and glass containers combined by residents into one cart. Each year we conduct an annual composition study of the single sort material to determine the percentage each material represents in the overall composition. RI Composition by Commodity of Each Recycling Stream During the composition study we weigh each truck before and after to detennine the weight of the material. Each truck has a stored weight that is updated regularly for accuracy. This process allows us to determine the initial weight of the material set out by residents during the period being analyzed. The composition study,. starts with Eureka Recycling storing all of t iTematerials collected in the city during a one-week'' period. These materials are stored ma separate bunker from all other materials at the facility. We sort the material separately from all other recycling at the facility. The -sorted materials are then baled or put into a hopper and transported with a forklift to the truck scale to be weighed. Finally, we weigh the total amount of each sorted material grade including the non -recyclable material (residual) to establish the percentage ofthe total tonnage that each material type represents in the overall I composition.
