Summary: This study investigated the influence of temperature oscillation on torrefied products and subsequent pyrolysis by conducting torrefaction experiments on elm branches at different temperatures and oscillation conditions. The results showed that temperature oscillation reduced the O/C and H/C ratios of the torrefied samples and increased their calorific value. It also increased the pyrolysis activation energy of the elm branches, with a higher value at higher torrefaction temperatures.

Summary: Fixed-bed pyrolysis of torrefied spruce wood at 800K showed char yields between 27-57 wt% (compared to 23 wt% for untreated wood), depending on pre-treatment temperatures and holding times. The thermogravimetric analysis revealed a low-temperature zone of slow rates followed by a high-rate zone with a well-defined peak. The torrefaction severity increased the temperature range of oxidative devolatilization and slowed down the oxidation rates, accompanied by changes in activation energies.

Summary: This study quantified the distribution patterns and evolution pathways of S and Cl during the co-combustion of textile dyeing sludge (TDS) and waste biochar (BC). The findings showed that by controlling the atmosphere and adding biochar, the retention of S in the bottom slag could be increased while its release to the flue gas could be reduced. Additionally, the addition of biochar and the control of the atmosphere also had an effect on the Cl content in the bottom slag, inhibiting the decomposition of organic Cl.

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: Co-pyrolysis of spent coffee grounds and polyethylene can reduce waste streams and pollution, while valorizing energy and by-products. The co-pyrolysis performance is influenced by temperature and blend ratio. The study revealed that co-pyrolysis consists of two stages, the degradation of spent coffee grounds followed by the depolymerization of polyethylene and lignin. The products of co-pyrolysis include a variety of oxygen-containing compounds, and CP73 showed the highest yields of hydrocarbons and alcohols, beneficial for further utilization.

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 study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

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.
