Eureka Recycling <br />Composition Analysis Methodology <br />Eureka Recycling collects materials in a single sort collection system with all <br />paper, cardboard, metal and plastic, steel, aluminum and glass containers <br />combined by residents into one cart. Each year we conduct an annual <br />composition study of the single sort material to determine the percentage each <br />material represents in the overall composition. <br />Composition by Commodity <br />of Each Recycling Stream <br />During the composition study we weigh <br />each truck before and after to detennine <br />the weight of the material. Each truck <br />has a stored weight that is updated <br />regularly for accuracy. This process <br />alloys Lis to determine the initial weight <br />of the _ ilaterial set out by residents <br />durind the period being analyzed. <br />The composition study, starts with Eureka <br />Recycling storing all of t e materials <br />collected in the city during a one-week- <br />period. <br />ne-weekperiod. These materials are stored ma <br />separate bunker from all other rlaterials at the <br />facility. We sort the material separately from <br />all other recycling at the facility. <br />She -sorted materials are then baled or put into <br />a hopper and transported with a forklift to the <br />truck scale to be weighed. Finally, we weigh <br />the total ainountiof each sorted material grade <br />including the non -recyclable material (residual) <br />to establish.the percentage ofthe total tonnage <br />that each material type represents in the overall <br />composition. <br />(651) 222 -SORT (7676) <br />www,eurekarecycling.org <br />Our mission is to reduce <br />waste today through <br />innovative resource <br />management and to reach <br />a waste -free tomorrow <br />by demonstrating that waste <br />is preventable, not inevitable. <br />An affirmative action, equal <br />opportunity employer. <br />® Printed on 100% postconsumer <br />recycled paper that was processed <br />without the use of chlorine. <br />
