Rapid infrastructure development worldwide is necessary for national development and economic growth due to booming population, globalization, and industrialization. However, at the cost of this, our environment is receiving a lot of pollution in air, soil, and water in the form of incompatible pollutants. This paper has intensely reviewed the use of biochar, a porous, carbon-rich solid by-product obtained through carefully controlled thermochemical conversion produced from different feedstocks of leftover biomass for infrastructure development and the cement industry, as structural concrete filler and recent advancements in technical and economic aspects for sustainable development. Carbon capture and storage (CCS) applications in concrete using biochar can play a vital role in reducing carbon footprint by adsorbing carbon and reducing cement usage. Concrete mixes can be produced using biomass residue based biochar from varying feedstocks in varying proportions, ranging from 0.5 to 10% by weight, and an analysis of its physical and chemical characteristics, as well as carbon capture ability, have also been discussed.

Adobe is resistant to sudden temperature changes and fire, acting as an effective thermal and acoustic barrier in construction. This article investigates the thermal, resistance, compression, plasticity and absorption properties of biocomposite adobe, proposing that the combination of adobe with agave bagasse significantly improves its efficiency compared to blocks composed of zacate, agave fibers and soil. This study was conducted in a mezcal and traditional adobe producing area in the State of Mexico, in line with the principles of circular economy. Results indicate that adobe enriched with agave bagasse presents several improvements in its physical and mechanical properties, which reduces its environmental impact. This research highlights the importance of adobe as a fundamental element in the revaluation of earthen architecture, contributing to the promotion of heritage identity.
