Use this worksheet to conduct a sustainability audit of Riordan Manufacturing, a virtual plastic injection molding company. Fill in all necessary information. Production stages that do not occur at this plant are marked as N/A.
Section 1: General Information
Company: Riordan Manufacturing, San Jose, California
Products: Assorted plastic products and testing new product designs and production
Section 2: Production
For each production stage, list input materials such as raw materials or output from previous stages, and output materials such as products, byproducts, wastes, or pollutants. Describe the process used at each stage and identify the least sustainable practices.
|Production Stage 1: Receiving | |Input Materials | |Output Materials | | |[pic] | | |1. High-density polyethylene (HDPE) plastic | |1. Particulates from the handling of damaged | |pellets | |bags of dyes that may cause air pollution | |2. Colorizing dyes | |2. Off-spec raw materials managed as a waste | |3. Ink | |3. Spilled materials that may cause land and | |4. Solvent cleaners | |water pollution | |5. Lubricating oils | |4. Wasted energy from lighting, heating, and | |6. Mold release agents | |processing equipment | |7. Electricity | | | |Briefly describe the receiving process: Small amounts of raw materials noted above are shipped to the R&D headquarters by truck to the front door.| |The material is then reconciled with the corresponding invoices and purchase orders. From there, the materials are placed in a large storage room | |located next to the R&D laboratories where tests are conducted on the materials. | |Briefly describe any nonsustainable aspects of this production stage: Particulates from the handling of dyes with damaged bags can cause air | |pollution. There exists a possibility that any spilled material could cause land and water pollution. There is wasted energy from the lighting | |and heating of the laboratories and in processing the equipment with lubricants. |
