Optimizing concrete block properties through the use of coconut shell and coconut shell ash: a multilayer perceptron approach

Mathematical Models in Engineering
This research utilized a multilayer perceptron model based on an artificial neural network (ANN) to improve concrete blocks by partially replacing stone dust and cement with coconut shell and coconut shell ash. From 35 experimental data points, 68.6 % were used for training and 31.4 % for testing.

Comparison of Adsorptive Removal and Oxidative Degradation of BODIPY Dye in Non‐aqueous Systems

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.
This study compares adsorption and advanced oxidation processes (AOPs) for removing dyes from ethanol to enhance waste to bioresource sustainability. Although AOPs were comparatively inefficient, coconut shell‐derived granular activated carbon offered a cost‐effective solution for solvent recovery and achieved higher dye removal, owing to surface ...

Evaluating the Elastic Modulus of Concrete Modified with Coconut Shell Ash

Journal of Engineering Research and Reports
This study investigates the potential of coconut shell ash (CSA), an agricultural waste product, as a supplementary cementitious material (SCM) for sustainable concrete production. CSA, obtained from calcined coconut shells and rich in reactive silica, alumina, and iron oxides, was used to replace ordinary Portland cement (OPC) at 0%, 10%, 20%, and 30%

Techno‐Economic and Environmental Assessment of Magnesium‐Impregnated Rice Husk Biochar for Nutrient Removal: A Scale‐Up and Prospective Soil Application Approach

Water Environment Research, Volume 98, Issue 6, June 2026.
A sequential system using magnesium‐impregnated rice husk biochar was evaluated through techno‐economic and life‐cycle assessment. The biochar first removes nitrate and phosphate from water and is then reused as a soil amendment, though high magnesium chloride costs constrain feasibility, highlighting the need for process optimization for large‐scale ...
