Sustainable cement and geopolymer mortars production incorporating beachside waste biochar for artificial reef applications
The sustainable management of biomass waste is a growing priority, problem of beachside waste (BSW) and its valorization potential remains underexplored. This study explored this gap by evaluating biochar produced from BSW as a partial replacement material in cement and geopolymer mortars for artificial reef applications. The carbonization process yielded 43.47 % of BSW char. Among the tested formulations, a geopolymer mortar comprising 90 % coal fly ash (FA) and 10 % BSW char (90FA10BSW) achieved the highest compressive strength at 37.73 MPa—significantly outperforming both control cement mortar (CM100, 22.51 MPa) and cement mortar with BSW char (90CM10BSW, 16.29 MPa). Bulk densities followed a similar trend (2250, 2120, and 2080 kg/m3, respectively). Strength gains with curing was evident, with a 24.56 % increase observed in 90FA10BSW over 28 day. Geopolymer mortars also exhibited lower pH levels in seawater (7–8) compared to cement-based mortars (10.2–10.7), highlighting greater environmental compatibility. Initial microbial colonization was highest in 90CM10BSW was observed on 90FA10BSW after 12 weeks. Despite the heterogeneity of BSW, these findings suggested that the BSW char could be a viable, low-impact additive that not only enhanced mechanical performance but also promoted marine habitat formation, supporting circular economy principles and blue carbon strategies in coastal waste valorization.
期刊介绍:
Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials.
The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy.
Key areas covered by the journal:
• Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation.
• Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal.
• Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes
• Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation
• Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
