The EU Bioeconomy Strategy underscores the importance of fostering a shared understanding of the shift to a bioeconomy and raising awareness of the diverse biomass demand. Since concrete is a globally prevalent material with a substantial environmental impact, it presents an enticing opportunity to integrate biomass products. Particularly, in the context of the burgeoning interest in digital concrete manufacturing, the use of bio-based cementitious “ink” could offer a promising resolution to the environmental challenges faced by the construction sector. This paper examines the current trends in substituting traditional concrete components with bio-based materials, such as bio-binders and bio-admixtures, for use in 3D printing technologies. Natural Language Processing (NLP) methods are employed to extract features from a substantial number of published documents automatically. This process aids in identifying the most frequently occurring bio-based ingredients and their biomass sources. Latent Dirichlet Allocation (LDA) is utilized to perform topic modeling and unveil underlying patterns within the corpus. A comprehensive discussion of both current and potential future developments is conducted.
