Influence of inorganic content on hydrochar quality from high-ash agar extraction waste via hydrothermal carbonization
Agar solid waste (ASW) has potential as a feedstock for hydrochar production because of its organic content; however, its high inorganic fraction, predominantly silica, limits its application. Furthermore, studies specifically investigating the hydrothermal carbonization (HTC) of ASW remain limited, given its high ash...

Data-Driven Optimization of Biodiesel Synthesis from Waste Cooking Oil over Sargassum sp.-Based Catalyst Using ANN and RSM
The continuous decline in fossil fuel reserves, together with growing environmental issues, has increased the urgency to develop sustainable alternative energy sources. Biodiesel produced from waste cooking oil (WCO) offers a promising solution; however, conventional homogeneous catalysts remain limited due to their...
