On a global scale, millions of tons of diverse agricultural residues are generated annually. Most of these wastes are burned or dumped in landfills, which causes environmental pollution. Addressing environmental issues arising from agricultural waste materials, in addition to mitigating heating and cooling expenses in the construction sector, is an interesting challenge for researchers. The utilization of agricultural wastes in different parts of construction is producing positive findings day by day, and investigating research in this field is a curiosity for researchers. This short study reviewed the most recent achievements in using agricultural wastes as a substitute or additive material for construction. Using these wastes as aggregate, ash (as a supplementary for cement), or fibers for foam concrete, insulation materials, etc. has been reviewed. This review has focused on very recent published papers. Several studies have demonstrated the effective influences of agro-waste materials in construction, like retaining the compressive strength (155 MPa) of concrete at standard levels and reducing heat losses in buildings (69% energy savings for brick insulated using wheat straw), as well as sound insulation. The use of agro-waste materials for insulation positively improved thermal conductivity, costs, and energy savings. However, some wastes did not provide a high added value, which shows that more investigations still need be performed to fill this gap in the research. Considering the global scale of agricultural waste generation and the potential benefits to both the environment and construction industry, continued research in this area is essential.

“…The natural fibres extracted agricultural crops such as coconut, sisal, jute, ramie past, pineapple leaves, cannabis, aspheric leaves, abaca leaves, jaws, dates, bamboo, banana, palm, hemp, linen, yarn, and honey cane are highly employed for imparting eco-friendly aspects without sacrificing the mechanical strength and are recommended widely due to local availability as well as economic feasibility [16][17][18][19]. As mentioned above, the rice straw has high mechanical strength and thermal conductivity due to the rich silica content making it climate-adaptive and functional for building infrastructure.…”

“…Straw bales have gained popularity in recent years as a viable material for building insulation and even the construction of miniature load-bearing straw houses, particularly in light of the need to reduce environmental effect. Despite their ability to sustain weights, straw bales are presently most commonly utilised as insulating filler materials for wood constructions [18]. Due to their enhanced impact resistance, they are also employed as support materials for fibre sheets in replacement to tiles [19].…”

There is an increasing awareness for adapting bioclimatic construction practices using agro-based green building materials to reduce the global warming impacts pertaining to the construction sector. In addition, lightweight construction is an emerging field of infrastructural development aiming to reduce the deadweight of the building by employing low density materials. Unlike conventional building blocks, the lightweight materials can be prepared in larger size and integrated easily to reduce the overall cost of construction. However, there is a need to identify cheaper and energy-efficient materials to minimize the net carbon emissions and to optimize the functionalities for any specific applications. The present study deals with the preparation of lightweight panels from agricultural by-products such as coconut fibres and paddy straws by optimizing their mixture proportioning and internal pattern of arrangement after pre-treatment with polyethylene glycol. Based on the test results, the concrete panels made of paddy straw have shown the highest reduction in weight compared to the conventional specimens (by 40%) and specimens with coconut fibre (by 25%). The results indicate that the concrete specimens made of the selected agro-based materials have improved mechanical (strength and durability), thermal and bioclimatic properties. The reduction in carbon emission depicts the critical dependency of bioclimatic construction on the selection of green materials. Therefore, a design methodology for sustainability assessment of agro-based building materials is formulated here in order to justify their suitability as green building materials.
