This study critically reviews recent advances in sago wastewater treatment technology and proposes a scalable, nature-based, integrated treatment framework that is in line with Malaysia’s Sustainable Development Goals (SDG6, SDG12, SDG14 and SDG15) and the principles of the circular economy. The proposed system combines anaerobic digestion, coagulation–flocculation, bioadsorption and phytoremediation. Scientific reports show that anaerobic digestion can reduce chemical oxygen demand (COD) by 70 %–95 %, but residual total suspended solids (TSS ≥200 mg/L) and nutrients (nitrogen ≥100 mg/L, phosphorus ≥30 mg/L) still require further treatment. The coagulation–flocculation method using natural biocoagulants successfully removes up to 81.5 % of TSS, and bioadsorption using activated carbon achieves impressive removal efficiencies of 81.16 % for total dissolved solids, 87.58 % for TSS, 91.32 % for COD and 48.66 % for biochemical oxygen demand (BOD) in sago industry wastewater. Phytoremediation using <em>Scirpus grossus</em> and <em>Chlorella pyrenoidosa</em> improves effluent quality by reducing TSS by up to 98 %, COD by up to 90.2 % and BOD by up to 93 %. These findings confirm the feasibility of a cost-effective, phased, sustainable, nature-based effluent treatment model.

This review explains the main reasons for deactivation in gas-phase systems. These include the buildup of carbon residues, formation of byproducts with nitrogen or sulfur, coke deposits, and damage to the material’s structure. We also discuss how surface defects, crystal structure, and particle shape affect both activity and durability. Different methods to restore activity are reviewed. These include heating, chemical cleaning, and light-based recovery. We also highlight recent advances in material design. Examples include single-site catalysts and porous structures such as metal organic frameworks. These materials can improve selectivity and resist deactivation.

As the global need for energy is growing rapidly, oil will serve as the main energy source for next ∼30 years. This energy requirement can be attained through the application of enhanced oil recovery (EOR) technology into marginal wells or by exploring new oil fields. However, the world has reached to a point where the oil recovery from existing reservoirs is more economical than drilling new wells. As the traditional recovery methods are inefficient and less economically sustainable, EOR emerged as viable method to extract the residual oil (∼50 %) from existing mature reservoirs. Within EOR, biopolymers are gaining popularity in the oil industry because of their accessibility, cost-effectiveness, environmental sustainability, viscoelastic behaviour, and biodegradability. Biopolymers like Guar gum, Xanthan gum, Cellulose, Welan gum, Scleroglucan, Schizophyllan, and Gum tragacanth are expected to replace synthetic polymers. However, the main challenge for biopolymers are microbial deterioration and shear-stress stability. Factors like temperature, salinity, polymer concentration, and chemical functional groups significantly impact biopolymer efficiency. To improve these parameters several studies have been conducted for the development of modified polymers using methods like grafting copolymerization, esterification with acylants, nanocomposite functionalization, crosslinking, and hydrogel formation. Recently, chemo-selectively modified and thermo-viscosifying biopolymers have been developed to increase sweep efficiency under reservoir conditions. Modified polymers may enhance EOR performance by viscosity increment, wettability alteration and emulsification.
