Coffee Husk Biomass: A Sustainable Solution for Eco- Friendly Bioconcrete with Enhanced Thermal Insulation
Session
Civil Engineering, Infrastructure and Environment
Description
Coffee husk resulting from crop processing are farm waste, generating a large amount of these organic materials after processing. Brazil, as the largest producer and consumer of coffee in the world, generates a significant amount of solid waste, approximately 4 million tons of coffee waste in 2020. Due to the low environmental impact of these materials, there are ecological alternatives for production of bioconcrete, creating lighter and more cost- effective materials, adding value to the waste and materials developed. The research evaluated the mechanical and physical properties of bioconcrete together with pozzolanic material, completely upgrading conventional aggregates with coffee husk biomass. The material showed low mechanical resistance to compression, with average values of 1.89 MPa, as expected due to its low density, making it unsuitable for structural purposes, but suitable for sealing. Furthermore, the material has a low thermal conductivity of 0.52 W/m•K, making it a viable option for the development of thermal insulating panels.
