Summary: The study introduced a method to distinguish emissions from the combustion of wood-based materials by classifying gas mixtures instead of focusing on individual pollutants. Results based on DMS and FTIR measurements were comparable, suggesting the effectiveness of the classification method.

Summary: This study investigated the hydrolysis process of wood waste from the French furniture industry. A novel method using an online FTIR spectrometer and a dilution system was successfully applied to measure the emission of formaldehyde and ammonia. The impact of operational conditions on the release of formaldehyde and ammonia was discussed. A mathematical model was also introduced to predict the behavior of formaldehyde and ammonia emissions during wood waste hydrolysis.

Summary: This study compared the effectiveness of microwave torrefaction (MT) and conventional torrefaction (CT) on herb residue (HR), showing that MT is more efficient in removing bound water and generating gases. Moisture content was identified as the key factor affecting torrefaction and energy consumption, while MT-HR exhibited superior gasification performance.

Summary: Pyrolysis is a promising technology for recovering valuable hydrocarbons from waste streams. This study investigated three types of waste plastics and their mixed forms to explore thermal cracking features, products distribution, and kinetic features. Results showed differences in pyrolysis products and reaction processes among different types of plastics, with synergistic effects observed during co-pyrolysis processes.

Summary: The aim of this study is to investigate the thermal behavior of Pinus wood pellets during torrefaction under different operational conditions and evaluate the potential application of the torrefied product in metallurgical processes. The experimental results showed that high torrefaction temperature and residence time decreased the mass yield. The best torrefaction conditions for biomass with potential application in metallurgical processes were in an inert atmosphere, at 290 degrees C and a residence time of 15 min.

Summary: The purpose of this study is to investigate the potential use of torrefied biomass of the genus Pinus as substitutes for metallurgical coke to reduce CO2 emissions. Thermogravimetric analysis was used to optimize the torrefaction conditions, and the physical and chemical characteristics of the torrefied biomasses were analyzed. The results showed that CV and PP torrefied at a temperature of 290°C for 30 min were the most promising. Solid-state ss-NMR characterization was used to analyze the kinetics of torrefaction.

Summary: The thermal conversion of waste furniture boards (WFB) was investigated using a coupled TG-FTIR system under inert atmosphere at different heating rates. Kinetic analysis revealed an average activation energy (Ea) of 175.91 (+/- 3.50), 171.41 (+/- 5.01), and 172.70 (+/- 5.06) kJ/mol, calculated using three model-free methods. Distribution of activation energy (DAEM) analysis indicated that the pyrolytic conversion of WFB is endothermic but favorable. A neural network model accurately predicted the thermal degradation, with a mean square error (MSE) of 0.3694 and adjusted R2 value of 0.9686. Pyrolysis of WFB produced molecules with -OH and -COOH functional groups, as well as small gas molecules such as CH4, CO2, and H2O.

Summary: This study investigates the individual pyrolysis and co-pyrolysis characteristics of kidney beans stalk (KS) and high-density polyethylene (HDPE) to realize the utilization of agricultural and plastic waste for alleviating environmental pollution. The results show the occurrence of synergistic and inhibitive effects during co-pyrolysis, with the most significant effect observed at temperatures between 470 and 510 degrees C. The gaseous products of KS pyrolysis mainly consist of oxygen-containing compounds, while those of HDPE pyrolysis mainly consist of hydrocarbons. Co-pyrolysis of samples with different proportions promotes or inhibits the production of certain gaseous products to varying degrees, and the activation energy during co-pyrolysis is lower than that of the pure sample. An artificial neural network (ANN) model is established to effectively predict the mass loss of a sample with temperature.

Summary: Excessive use of fossil fuels has had a significant impact on global warming and the energy crisis, necessitating the promotion and development of alternative energy sources. Converting waste biomass into energy is important for solid waste management. This study improves the fuel properties of spent coffee grounds (SCG) through torrefaction and identifies the optimal conditions for this process.

Summary: This study evaluates the possibility of using catalytic torrefaction as a pretreatment to improve wood pyrolysis and combustion for greener biochar production. The findings show that catalytic torrefaction can significantly decrease the devolatilization peak during combustion, making the wood's combustion similar to that of coal.

Summary: The pyrolysis and combustion processes of camphor biomass waste were studied using DSC/TGA-DTG/GC-MS/FTIR, with non-isothermal kinetics investigated under different heating rates. The results indicated different phases of mass loss, accompanied by exothermic and/or endothermic reactions.Activation energies for main mass losses in the second phase were determined to be 39.98-56.25 and 109.26-135.84 kJ/mol, respectively.
