Life Cycle Assessment of Hemp-Silicone Elastomer Composites in Direct Ink Writing

A comparative life cycle assessment quantifies the environmental impacts of direct ink writing additive manufacturing for hemp-silicone elastomer composites. The dataset contains results from ReCiPe 2016, Cumulative Energy Demand, and IPCC 2021 GWP100 methods, comparing a 5 wt.% hemp composite to a neat silicone elastomer reference. Environmental impacts are dominated by silicone elastomer production, with printing energy contributing a minor fraction of total life cycle impacts.

Use Cases

• Comparing environmental impacts of neat and hemp-reinforced silicone elastomers based on ReCiPe endpoint scores.
• Analyzing the effect of biobased filler substitution on greenhouse gas emissions using IPCC 2021 GWP100 results.
• Assessing the contribution of manufacturing energy versus material production to total impacts using Cumulative Energy Demand data.
• Conducting sensitivity analysis on the effect of increased hemp loading (e.g., to 10 wt.%) on environmental performance.

Strengths

• Dataset is in the public domain (U.S. Public Domain license), enabling unrestricted reuse.
• Results are based on three established environmental impact assessment methods: ReCiPe 2016, CED, and IPCC 2021 GWP100.
• Includes sensitivity analysis showing the effect of increasing hemp loading from 5 wt.% to 10 wt.%.

Limitations

• Column names and a precise row count are not provided, limiting understanding of the dataset's internal structure.
• The dataset's temporal coverage and specific geographic scope of the assessment are not explicitly stated.
• The file size (83,101 bytes) suggests the dataset is relatively small, potentially containing only summary results rather than raw LCA inventory data.
