There are two main sources of activated carbon production - coal and lignocelullosic materials. Recently, scientists have been focused on activated carbon preparation based on agricultural waste and lignocelluloses materials, ...

In this study, nutrients release/adsorption from/by raw poultry manure-derived biochar produced at a pyrolysis temperature of 600 °C (RPM-B) was assessed under static and dynamic conditions. Batch sequential leaching ...

Biochar is the solid by-product of biomass thermochemical conversion via pyrolysis technique. Biochar addition to croplands as an organic amendment can improve soil properties and increase agricultural productivity. However, ...

Lignite, as an available and low-cost material, was tested for cadmium (Cd) and copper (Cu) removal from aqueous solutions under various static experimental conditions. Experimental results showed that the removal efficiency ...

The aim of the present study is to investigate the adsorption of dissolved organic matter in olive mill wastewater (OMW) onto biochar as a pretreatment step within an eco-friendly OMW management process. Firstly, the ...

The increasing prevalence of toxic elements such as nickel (Ni) in the environment poses a significant threat to human health due to its carcinogenic effect. The study investigates the Ni biosorption potential of three ...

The recent regulations pertaining to the circular economy have unlocked new prospects for researchers. In contrast to the unsustainable models associated with the linear economy, integration of concepts of circular economy ...

In Tunisia, olive mill waste water (OMW) is discharged into evaporation ponds where they turn into solid waste (OMSW) and become a serious threat to the environment. This paper addresses for the first time how to valorize ...
