Efficient and green degradation of BDE209 in soil remains a great challenge. In this work, a microwave catalytic material (ZFO-PBC) was synthesized by recycling and phosphoric acid-modified biochar (PBC) from abandoned buildings via the treatment process. The combination of ZnFe₂O₄ with PBC enhanced the magnetic and reflection losses of the material in the microwave field, which improved the microwave absorption and electron transfer capabilities and accelerated the generation of active substances. The ZFO-PBC/MW/PDS system exhibited excellent oxidation performance (91.5 % degradation of BDE209 in 5 min) and pH tolerance. BDE209 was degraded by singlet oxygen (¹O₂), superoxide radical (O₂^•−), and electron transfer mechanisms. Density functional theory (DFT) calculations, liquid and gas chromatography-mass spectrometry (LC<img>MS and GC<img>MS) analyses revealed that the ether bonds in BDE209 were unstable under microwave conditions and were prone to breakage to form bromophenolics. This process avoids the production of lower brominated biphenyl ethers, which greatly reduces the toxicity of byproducts during the degradation of BDE209.

Under these conditions, the prepared fluxed metallized pellets exhibited a compressive strength of 4125 N/P, an RDI_+3.15 of 75.2 %, and an RDI_+3.15 of 65.2 %.

In addition, variations in the compressive strength as an important metallurgical indicator were closely related to the formation of wustite and olivine at lower basicity levels. Higher basicity facilitated the formation of dicalcium silicate (C₂S), whose phase transition-induced volume expansion caused self-pulverization of the pellets during the cooling process. The presence of solid solutions phases, such as gehlenite (Ca_xMg_2-xSiAl₂O₇) and olivine (Ca_xFe_2-xSiO₄), played an important role in preventing fragmentation and pulverization, effectively improving the RDI_+3.15 and RDI_+6.3 values of the pellets.

Thermodynamic modelling of the system was conducted in Aspen Plus V12, applying the Gibbs free energy minimization method and accounting for all by-products. Key decision variables, including the water-to-glycerol ratio, CO₂-to-glycerol ratio, and reforming temperature, were examined for their impact on process performance. Results demonstrated that bi-reforming glycerol is more advantageous for syngas production compared to dry reforming, as it operates at lower temperatures, reducing coke formation. A glycerol bi-reforming process was simulated and optimized using MOO to maximize syngas production and CO₂ conversion while minimizing exergy loss and CO₂ emissions. The optimization revealed trade-offs among the objectives, with the Pareto front showcasing optimal solutions. Specifically, a higher water-to-glycerol ratio favoured a higher H₂-to-CO ratio but led to decreased CO₂ conversion and increased energy consumption and CO₂ emissions. The net flow method (NFM) is used to select the best optimal solutions from the Pareto front solutions based on the weight of the objective functions. Despite these trade-offs, bi-reforming of bio-glycerol was shown to be a viable method for producing syngas with a high H₂/CO ratio and low CO₂ emissions.

Experimental results showed that the water contact angle of OPCM increased from 0° to 152.6°, signifying a change in wettability from superhydrophilicity to superhydrophobicity. And the surface temperature of OPCM rose rapidly from 25°C to 76.2°C within 1 min under the simulated sunlight irradiation of 1.0 kW/m². Furthermore, three kinds of heavy oils with viscosities of 44204 mPa·s, 9373 mPa·s, and 3671 mPa·s were selected for the absorption test. The test indicated that the maximum absorption capacities of OPCM for these oils were 126 g oil/g OPCM, 117 g oil/g OPCM, and 114 g oil/g OPCM, respectively. At the same time, from the perspective of circular economy, after 11 cycles of oil absorption, the absorption capacities of OPCM remained at 107 g oil/g OPCM, 102 g oil/g OPCM, and 100 g oil/g OPCM. Because of the photothermal conversion property and thermal conductivity of OPCM, the viscosity of heavy oil decreased and the fluidity increased. Additionally, the capillary force and hydrophobic interaction improved the absorption efficiency of OPCM for heavy oil.

Oilfield produced water is a type of lithium-containing wastewater generated during oil extraction processes, offering significant potential for resource recycling. However, conventional lithium recovery methods, such as solvent extraction and electrochemical techniques, exhibit low efficiency due to the presence of organic substances (e.g., grease, ammonia nitrogen, COD) and inorganic contaminants (e.g., heavy metals, salts). To enhance lithium recovery efficiency from oilfield wastewater, this study synthesized lithium manganese oxide (Li₁.₆Mn₁.₆O₄) via a soft chemical method using various lithium and manganese sources, followed by surface modification with lanthanum oxide (La₂O₃). The La₂O₃-modified material was applied for cyclic adsorption and recovery of Li⁺ from oilfield produced water. Experimental results indicate that combining MnCO₃ and LiOH as manganese and lithium sources in a 1:1 ratio produces the Li₁.₆Mn₁.₆O₄ precursor with optimal adsorption capacity and minimal manganese loss. Through multiple adsorption-desorption cycles using both simulated and actual oilfield produced water samples from various locations, it was demonstrated that the inherent chemical inertness of La₂O₃ coating on Li₁.₆Mn₁.₆O₄ effectively mitigates manganese dissolution. La₂O₃ coating effectively mitigates manganese loss from Li₁.₆Mn₁.₆O₄. After 10 cycles, the manganese loss rate remained below 1.5 %, with the adsorption capacity sustained at 25 mg·g⁻¹ .
