The depletion of fossil fuels has led to a search for new methods of fuel and chemical
production from biomass. One of the methods of converting biomass into valuable products …

A variety of sludge originating from wastewater treatment is increasingly accumulating
worldwide, especially in the developed regions. Fortunately, phosphorus (P) in sludge can …

Among the various problems the world is facing, two problems are addressed in this paper.
On the one hand, biomass, the fourth largest and most important renewable energy option …

Pyrolysis of sewage sludge in the presence of humic acid (HA), CaO and kaolin was
investigated in order to examine the effects of organic and inorganic constituents on the …

The high content of nitrogen in hydrochar produced from hydrothermal carbonization (HTC)
of sewage sludge (SS) leads to serious NOx pollution when the hydrochar is used as a solid …

The recovery of phosphorus (P) from sewage sludge through pyrolysis is one of the most
promising alternatives to alleviate the shortage of P supply in the future. Adding calcium …

The aim of this study was to clarify the multiple influence mechanisms through which Ca
influences the emission of NOx precursors (NH 3 and HCN) during sewage sludge pyrolysis …

Oily sludge (OS) has attracted special interest because of its hazardous nature and high
potential as an energy resource. This study investigated the oil recovery from OS by thermal …

Co-pyrolysis of biosolids (BS) and wheat straw (WS), as well as their treated variants, was
performed in a fluidised bed reactor at 500℃. Under mild acid pre-treatment conditions (3 …

High concentrations of inorganic matter such as silicates, alkali and alkaline earth metals
(AAEMs), and heavy metals (HMs) in biosolids limit their pyrolysis conversion to high-value …
