Soil pollution by heavy metals (HMs) is a major environmental problem around the world. The addition of biowaste-based stabilizers for HM remediation has recently gained attention due to its relatively low cost and eco-risk, abundance, ease operation, quick results. Among these stabilizers, shell (crustacean shell, bivalve eggshell), starfish, bone-based are particularly attractive because their high Ca P contents, allowing highly efficient immobilization simultaneous supplement nutrients soil. However, comprehensive review focusing on currently missing. Therefore, this attempts summarize efficiency mechanisms associated with stabilization, perform an operation estimation comparison. Cost comparisons among different widely ignored in reviews lack reliable tools or methods. practical application soil remediation, one most important factors consider. Thus, simple but reasonable method developed discussed review. Bivalve shell-based demonstrated promising results HMs terms higher performance lower cost. Current research limitations, challenges, recommendations regarding possible future directions also provided.

This study aimed to produce activated carbon from desilicated rice husks using various carbonization and activation methods, including a tube furnace, muffle artisanal pyrolysis. The resulting carbons were characterized for their adsorptive capacity through the determination of iodine number methylene blue adsorption; these are key indicators specific surface area adsorbent quality. Advanced characterization techniques employed, such as scanning electron microscopy (SEM), which revealed highly porous irregular structure, energy dispersive X-ray spectroscopy (EDS), confirming effective removal impurities optimization elemental composition. Atomic force (AFM) demonstrated favorable roughness adsorption processes. Among samples, CaDH162-CADH53 exhibited highest performance, with an 1094.8 mg/g yield 93.5%, signifying high capacity. treatments phosphoric acid calcium carbonate significantly improved further enhancing material’s properties. In conclusion, produced in this optimal physicochemical properties water purification contaminant treatment applications. These findings highlight potential agricultural waste, husk, sustainable scalable alternative industrial-scale production.

Remediated water reuse is becoming vital for sustainable management, reducing the strain on freshwater resources, particularly in agriculture and industrial activities. Behind application irrigating crops processes, treated should be employed indirect direct potable use. In latter case, traditional approaches to wastewater treatment have been found inefficient, especially concerning biological contamination, persistent organic pollutants (POPs) and/or contaminants of emerging concern (CECs). Given that, according its origin foreseen use, each needs a specific treatment. A plethora new or improved materials, combinations different treatments check analyses are continuously developed tested at laboratory scale, first, necessary but not sufficient, step towards solution. Various innovative were pilot reduced number procedures applied full resulting significant production remediated desired quality. The present review focuses most recent outcomes obtained from remediation both scales discusses gaps which still hinder exploitation solutions advancements real-scale application.

The valorization of agricultural residues assumes a pivotal position in the circular economy by transforming waste into useful and environmentally friendly product, with cultivation corn, as one world’s predominant crops, being crucial. This article aimed to investigate feasibility using from corn crop biofuels, going more in-depth determining effect that variety may have on its thermal qualities. Specifically, 12 samples were studied three main groups: conventional, forage, transgenic varieties. To achieve this, proximate ultimate analyses, thermogravimetric differential scanning calorimetry conducted, along study gas emissions statistical comparison different From results obtained, it is worth highlighting low ash content all (between 5.55% 8.42%) high calorific values (higher than 17 MJ/kg cases), well optimal for both pyrolysis combustion processes. Significant differences found between varieties; particular, was observed forage presented conditions application represent potential competitive advantage
