Investigation on the reuse of the sugar co-products (Bagasse, Molasses, and Ash) as industrial wastes in the production of Compressed earth blocks

Abstract

Increasing attention should be paid to industrial wastes to conserve energy and protect the environment. The accumulation of industrial wastes affects negatively public health and the environment. This paper is a review of literature on the valorization of sugar industry wastes to merge them into the construction industry and turn them into useful and cheap materials for building. Through this work, we identified various valorizations ways of sugar industry wastes to develop an efficient flow chain production of sustainable construction clay bricks. The proposed combination of earth and sugar co-products will reduce the cost of clay bricks and enhance their mechanical, thermal, and environmental characteristics. The objective of this study is to present the physical, chemical, mechanical, and thermal properties of each residue of sugar extraction processes with comparisons of literature findings. Furthermore, this study analyses the effect of adding sugar co-products to Compressed Earth Blocks. From the results of research, we observed that cellulosic and hemicellulosic fractions make bagasse good on mechanical potential and thermal characteristics as raw material that is used as reinforcement to CEB. Thereby, it was found that the addition of 12% of molasses to Compressed Earth Blocks (CEB) is optimal in terms of compression resistance, and the mechanical strength is not affected by the addition of bagasse ash. Hence, incorporate ash can into such addition just for its pozzolanic behavior.
