Sustainable Manufacturing: There Are Apps for That Software that supports sustainable manufacturing and environmentally conscious products help make going green somewhat easier. Sustainable manufacturing? There's software for that. It comes under several guises: software for eco-design, clean production, green supply chain, waste management and reutilization (including demanufacturing, product recovery, and recycling). Fundamentally, this software boils down to some form of database management and presentation, or computer-aided analysis (CAE) and simulation. Here are some examples. SUSTAINABILITY OUTSIDE THE FACTORY There's a lot of compliance data to collect related to envi- ronmental and socially conscious issues, including that from REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) and RoHS (Restriction of Hazardous Substances), both European Union (EU) mandates; confict minerals laws in the EU and the U.S. (Section 1502 of the Dodd-Frank Act); and other regional and industry regulations, such as IEC 62474 (Material Declaration for Products of and for the Electrotechnical Industry). Might as well collect all that data in some central reposi- tory within an enterprise. A product lifecycle management (PLM) is a good repository. For instance, Teamcenter, the PLM system from Siemens PLM Software ( siemens. com ), can automate the supplier material and substance disclosure (MSD) process and manage materials and substances as components of the product defnition. To do that, Teamcenter has an integration component to the International Materials Data System (IMDS), a database maintained by Hewlett-Packard. (In the automotive industry, BY LAWRENCE S. GOULD, Contributing Editor suppliers must submit their supplier material declarations to IMDS.) The Teamcenter-IMDS integration automatically synchronizes updated material data sheets in IMDS to a company's design/engineering systems, and vice versa. The hassle of updating MDS is further minimized by Teamcenter supporting various material disclosure standards (such as IPC-1752A, the Materials Declaration Management Standard). To help sustainable product design, the Teamcenter-IMDS integration helps OEMs check the compliance of all their suppliers listed in a bill of materials (BOM) early in the design process. For example, Teamcenter uses pre-created specifcations to whip through the design BOM and tag any material that's not compliant with environmental and social mandates. A rules editor lets users create and manage their own custom rules, such as for compliance to internal guidelines or specifc requests coming from supply chain partners. Teamcenter can also notify customers if a new element or substance has been added to REACH, thereby triggering a recheck of the design BOM. Teamcenter can also direct users to "green" and "approved" materials from within NX, CAD software also from Siemens PLM, before making material assignments. As needed, "You not only want to optimize your throughput, you want to analyze the energy utilization." 40
