Summary: This research focuses on the chemical transformation of biocoke, a solid biofuel produced under subcritical water. The authors used ATR-FTIR to study the effect of lignocellulose substances on the structural reaction and compressive strength of biocoke for industrial quality control. They found that changes in the 1800-1500 and 800-400 cm-1 regions of FTIR were related to the maximum compressive strength of biocoke. Lignin cleavage caused changes in the 1800-1500 cm-1 region, while higher cellulose content led to alterations in the 800-400 cm-1 region and decreased the biocoke's compressive strength.

Summary: This study investigates the impact of biodiesel additives on soot formation and mitigation, revealing that a blend of 25% MB-75% diesel fuel has the lowest sooting propensity and activation energy for soot oxidation, while a blend of 25% MC-75% diesel fuel has relatively higher sooting propensity and activation energy. This suggests that the structural differences in the surrogate fuels influence soot formation and oxidation kinetics, an important consideration for global multiphase kinetic models for biodiesel-diesel fuel combustion.

Summary: The utilization of natural ores and mine waste as substrate in constructed wetlands can enhance nutrient removal performance. However, the potential negative environmental effects of contaminants leached from mine waste are not well understood. This study investigated the long-term feasibility and key removal mechanisms of different constructed wetlands using three types of mine waste as substrates. The results showed that the addition of mine waste increased the removal of total phosphorus and total nitrogen. The higher removal of phosphorus is mainly attributed to the strong binding mechanism of phosphate with the leached oxides and hydroxides of manganese, iron, and/or aluminum. Moreover, the integration of mine waste in constructed wetlands stimulated biofilm establishment and enriched the relative abundance of key functional genes related to the nitrogen cycle.

Summary: Two constructed wetland-microbial fuel cells (CW-MFC), including a closed-circuit system (CCWMFC) and an open-circuit system (OCW-MFC) with petroleum coke as electrode and substrate, were constructed to explore the effect of multiple key factors on their operation performances. The CCW-MFC system showed better performance compared to a traditional CW, achieving high removal efficiencies of COD, NH4+-N, and TN. The CCW-MFC system also exhibited a greater denitrification ability due to the presence of Thiothrix and the possible quorum sensing within the denitrifying microbial community.

Summary: The substantial climate change mitigation potential of restoring peatlands through rewetting and intensifying agriculture to reduce greenhouse gas (GHG) emissions is largely recognized. The green deal in Denmark aims at restoring 100 000 ha of peatlands by 2030. Recent advances established the functional relationship between hydrological regimes, i.e., water table depth (WTD), and CO(2 )and CH(4 )emissions. We lay the foundation of developing a high-resolution WTD map for Danish peatlands and derive a national GHG emission estimate for peat soils. The estimated annual GHG emissions are 2.6 MtCO(2)-eq, which is around 15 % lower than previous estimates. Alternative restoration scenarios and the prioritization of fields in the rewetting strategy significantly influence the GHG reduction potential.
