Environmental Performance of Tannin-Stabilized Unfired Earth Bricks: A Comparative Life Cycle Assessment
Unfired earth is widely recognized as a construction material with high environmental potential, mainly due to the absence of firing and the possibility of local sourcing. However, its industrial deployment remains limited. Mechanical performance and...
Ex-ante life cycle assessment of cellulose nanocrystals production from waste biomass: implications of applying different upscaling approaches
Session 14: Life Cycle Innovation in the Bio-Economy
Nanocrystalline cellulose is a nano-structured biomaterial often applied in biopolymers to enhance technical performance. Cellulose nanocrystals (CNC) have been obtained in the laboratory from lignocellulosic wastes, e.g., mango seed shells [Ref.1]. Assessing the environmental impacts...
From Lab to Industrial Scale: Engineering-based Prospective Scaling for the LCA of Bio-based Nanocellulose Electrodes
Electrocardiography (ECG) is a fundamental practice in modern healthcare which is utilizing billions of single-use silver/silver chloride (Ag/AgCl) electrodes annually. This drives continuous extraction of non-renewable resources and generates significant amounts of non-recyclable waste. As...
Impact of upscaling on the environmental impacts of Hydrogen Plasma Smelting Reduction (HPSR) process
It is essential to understand the future environmental impacts of emerging technologies, while still at the design stage, in order to make informed decisions. Projecting the process flow diagram (PFD) of the deployment-ready state of...
Promise vs. Performance: What 14 LCA Case Studies Reveal About Emerging Bioeconomy Technologies
The transition towards a sustainable bioeconomy requires robust assessment approaches for technologies at early development stages. At the same time, limited biomass availability and competing uses create trade-offs, increasing the importance of evaluating residue-based pathways...
Prospective life cycle assessment of brewers’ spent grain valorisation via edible mushroom cultivation
Brewers’ spent grain (BSG) is among the most abundant by-products of the food industry, with approximately 0.65 million tonnes generated annually in Europe. Currently, BSG is mainly used as livestock feed or as a substrate...
Prospective Life Cycle Assessment of lignin oxidation integration into a state-of-the-art kraft pulp mill
The modern kraft pulp mill has evolved from a dedicated fiber production facility into an integrated forest biorefinery, where valorization of all biomass fractions and side streams provides a competitive advantage. Several lignin valorization concepts...
Regionalised LCA of territorial food supply: assessing the environmental performance of French contrasted scenarios up to 2050.
Recently, the French agency for ecological transition (Ademe) proposed contrasted prospective scenarios to achieve carbon neutrality by 2050 including a focus on the food sector. However, these studies remain focused on climate change and do...
Resource Criticality & Prospective LCA of Metal Additive Manufacturing: Materials, Processes and Circularity Scenarios
Metal additive manufacturing consists in producing parts by adding material layer by layer from a digital model. This technology offers strong potential in terms of design freedom, functional integration, and material resource optimization. Despite these...
