Owing to the increasing global demand for carbon resources, pressure on finite materials, including petroleum and inorganic is expected increase in future. Efficient utilization of waste resources has become crucial sustainable resource acquisition creating next generation industries. Rice husks, which are abundant worldwide as agricultural waste, a rich source with high silica content have pot...

This paper addresses the analysis of hydrothermal carbonization Tetra Pak residues using diluted sulfuric acid to obtain hydrochars for cleaning water polluted by heavy metal ions. The hydrochar samples were prepared under different conditions, and a detailed study their composition, textural parameters, surface functionalities was performed. It found that dwell time wastes significantly affect...

Hydrothermal carbonization (HTC) is a promising technology used for bioenergy conversion from bio-wastes such as sewage sludge, livestock manure, and food waste. To determine the optimum HTC reaction temperature in maximizing the gross energy recovery efficiency of poultry slaughterhouse sludge cake, a pilot-scale HTC reactor was designed and operated under reaction temperatures of 170, 180, 19...

Lignocellulosic biomass is one of the most abundant yet underutilized renewable energy resources. Both anaerobic digestion (AD) and hydrothermal carbonization (HTC) are promising technologies for bioenergy production from biomass in terms of biogas and HTC biochar, respectively. In this study, the combination of AD and HTC is proposed to increase overall bioenergy production. Wheat straw was an...
