Life Cycle Assessment Gaps
Research gap analysis derived from 2 biology papers in our local library.
The gap
There is a need for unified and comprehensive life cycle assessments (LCAs) across various bio-based materials and products to address inconsistencies in environmental impact evaluations.
Consensus across the literature
The papers collectively highlight the importance of LCAs but point out current gaps, particularly in methodological consistency and full lifecycle coverage.
Research trend
Emerging — attention growing, methods still coalescing.
Supporting evidence — 2 representative gaps
- Comprehensive evaluation of the environmental performance and durability of biochar-incorporated concrete (2026) · doi
A more comprehensive sustainability evaluation would require the inclusion of full life-cycle stages (cradle-to-grave or cradle-to-cradle) in future studies, beyond the current A1-A3 stages.
Keywords: cradle stages comprehensive sustainability evaluation require inclusion full life cycle grave future beyond current - Planetary health diet adherence, nutritional adequacy, and environmental footprints: a cross-sectional study in Turkish adults (2026) · doi
Environmental footprint calculations integrated two different databases (SEL for primary data, SHARP-ID for supplementary values) with inconsistent system boundaries: SEL estimates impacts only to the distribution center while SHARP-ID includes the full cradle-to-plate cycle. This methodological discrepancy introduces uncertainties that could be resolved by establishing unified Türkiye-specific carbon footprint and water footprint coefficients across the full supply chain.
