Otto Environmental Systems 800-795 -OTTO (6886) • www.otto-usa.com City of South Bend, IN Bid for Six Thousand (6,000) More or Less Universal/Nestable Refuse and Yard Waste Containers Bid Opens: January 10, 2023 COMMENTS The Multi-System Design “MSD” refuse containers manufactured by Otto Environmental Systems are injection- molded with numerous premium features. The design specifications of the Otto MSD carts will meet virtually all of the specifications outlined in this bid request. MANUFACTURING PROCESSES AND MATERIALS: PLASTIC MATERIAL: Base plastic resin must be first quality low-density polyethylene supplied by a national petrochemical producer. The Otto refuse containers are manufactured by an injection molding process. The injection molding process is capable of making products with complex designs that would not be possible by other processes of manufacturing, such as rotational molding and blow molding. Injection molding provides consistency and durability. The injection- molding process requires the use of high density polyethylene (the bid calls for linear low polyethylene which is the proprietary material used in the rotational-molding process). It is useful to keep in mind that the “minimum property levels” outlined in the bid specifications are references to results from ASTM laboratory procedures that are performed on test samples molded of polyethylene resins and do not in fact establish the strength and durability of an actual container. While all suppliers of rollout refuse carts use polyethylene as their material of choice, each of the different molding technologies (i.e., injection, rotational) requires a different “recipe” (formula) specifically blended to their specific technology. These ASTM tests were designed to help manufacturers select the correct resin formula for their particular molding application by differentiating the physical properties of various resin formulas. The resin properties described in this bid specification are typical for the resins formulated for use in one particular molding process – rotational-molding. The resin formula that Otto uses to produce the best injection-molded carts will have different laboratory test properties than the rotational-molding grade polyethylene. We have attached a laboratory report detailing the properties of the resins formulated for use in the Otto injection-molded carts. In reality, the ASTM testing results are only useful if used as a point of comparison between different manufacturers that use the same molding process.
