Welcoming the New ASTM Standards for Manufacturing Processes
At SSC, we have been calculating environmental impact in manufacturing processes using process flow diagramming for years. When conducting life-cycle assessments, process-flow diagramming provides a visual and a data-based representation of every input and output in a manufacturing process to achieve the most accurate results.
But mapping manufacturing processes becomes difficult because of the wide variety of technologies, inputs, outflows, variations inside of a single facility or lack of information from upstream or downstream. Additionally, the standards and software tools used to calculate processes can vary in their accuracy and be limited in their flexibility, unable to adapt to a wide variety of industries.
Complexity is par for the course when determining environmental impact of a manufacturing process.
The newly released ASTM International standard for calculating the environmental aspects of manufacturing processes (ASTM E3012-16), developed by the National Institute of Standards and Technology (NIST), promises to be a step forward in guiding sustainability professionals through a systematic and more comprehensive, yet flexible, way to calculate environmental impacts based on a graphical process-flow modeling.
NIST systems engineer Kevin Lyons, who chaired the ASTM committee that developed the manufacturing sustainability standard, describes it as similar as tracking financials. “You have to gather income and expenditure data, run the numbers and then use the results to make smart process changes — savings, cutbacks, streamlining, etc. — that will optimize your monthly budget,” he said. “We designed ASTM E3012-16 to let manufacturers virtually characterize their production processes as computer models, and then, using a standardized method, “plug and play” the environmental data for each process step to visualize impacts and identify areas for improving overall sustainability of the system.”
The updated database will help standardize terminology and structure of mapping and reporting manufacturing process impact, reducing complexity in mapping manufacturing processes, and thereby helping companies fully and accurately understand environmental impacts and work toward reducing them.
