Summary: This study investigated the combustion characteristics and NOx/SOx emissions at different pressures using a lab-scale pressurized oxy-fuel combustion system. Higher pressure resulted in increased heat recovery rate, lower combustion temperature, and higher heat flow rate with higher H2O content in flue gas. NOx and SOx emissions decreased under low H2O conditions in flue gas, and significantly decreased under high H2O conditions at 10 barg. The study identified the effects of H radicals and H2O fraction on the oxidation and decrease of NOx and SOx.

Summary: In the combustion of textile dyeing sludge, controlling sulfur (S) species through flue gas-to-ash processes is crucial for achieving circular economies. The experimental study found that temperature and blend ratios play significant roles in transforming S in TDS, with the addition of spent mushroom substrate (SMS) and calcium oxide (CaO) enhancing desulfurization efficiency. The results suggest that a combination of SMS and CaO can improve the retention of S and enhance the decomposition of calcium sulfate (CaSO4).

Summary: The co-combustion of textile dyeing sludge (TDS) and cattle manure (CM) can enhance resource circularity and pollution control. However, the migration and transformation behaviors of ashes during this process are still unclear. This study used thermogravimetric experiments and thermodynamic simulations to investigate the transformation and migration of co-combustion ashes and the interactions involved. The addition of TDS increased the environmental safety of Ni and Cr by transforming them from extractable form to stable form. P dominated S in the reaction with Ca, promoting the emission of S-containing gases and the generation of apatite P. The reactions between minerals in CM and Ca in TDS resulted in the formation of calcium silicate, reducing the S-fixation ability of Ca and increasing the emission of S-containing gases. These findings provide insights into the interactions among minerals, heavy metals, and specific elements, and their impact on pollutant emissions, thus enhancing pollution control strategies.

Summary: This study explores the effects of HCl and H3PO4 pretreatment on the physi-chemical properties and decomposition characteristics of an As-hyperaccumulator. The results show that HCl pretreatment retains the main components of the hyperaccumulator while introducing Cl to the carbon chain, while H3PO4 pretreatment destroys the carbon chain and removes more organics and minerals. HCl pretreatment improves the pyrolysis efficiency, while H3PO4 pretreatment decreases leaching of heavy metals. These findings provide valuable insights for the management and utilization of post-harvest hyperaccumulators.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
