Summary: Turkey heavily relies on fossil fuels as an energy importing country, leading to environmental issues and energy security concerns. This study in the Marmara Region highlights the potential of using biowastes to meet more than half of the region's electricity demand, providing cost-effective options such as direct combustion of agricultural wastes and conversion of animal wastes to biogas in CHP plants.

Summary: The world market for solid biofuels, particularly pellets and briquettes, has seen an increase in recent years. This study provides a systematic review and exploratory Life Cycle Assessment (LCA) of biomass briquettes and pellets produced in Latin America, highlighting their environmental impacts and suggesting potential opportunities. The review showed that most publications focused on the thermo-mechanical properties of pellets and briquettes, rather than their environmental impacts. An LCA was performed based on gathered data, with a focus on global warming potential, terrestrial acidification potential, freshwater eutrophication potential, cumulative energy demand, land use, and water consumption. The study found that dedicated systems for pellets and briquettes production showed lower environmental impacts compared to multifunctional systems. The political implications of these findings include the potential for implementing emission trading systems in Latin America and beyond.

Summary: With the increasing energy requirements, biomass resources have emerged as a promising alternative energy source due to the pollution problems associated with fossil fuels. The conversion of biomass to biofuels can be achieved through thermochemical or biological processes, with catalytic approaches playing an important role. The development of novel nanocatalysts is crucial for improving product quality and optimizing operating conditions. This study focuses on biofuels, discussing aspects such as classification, production technologies, and strategies for increasing yield using nanocatalysts.

Summary: Forest biomass used as feedstock for bioenergy production can achieve greenhouse gas (GHG) emission reduction in the short term, but the time to carbon parity varies depending on biomass type and assumptions. The use of primary biomass (roundwood) requires a longer time to achieve carbon parity, while secondary biomass (mill residues) can achieve GHG benefits in a shorter time frame. The adoption of intensive silvicultural practices can reduce the time to carbon parity, but there are uncertainties regarding long-term soil carbon storage.

Summary: Pakistan has been struggling with electricity shortages since 2005, hindering the country's growth in agriculture, industry, and services sectors. This study used LEAP & REG; software to forecast Pakistan's energy mix from 2022-2050 under baseline and transformation scenarios. The baseline scenario focuses on increasing hydroelectric power, while the transformation scenario emphasizes the use of biomass. The study recommends the transformation scenario due to retiring hydro plants and limited budget for new constructions. By utilizing biomass-based distributed power generation, Pakistan could generate enough sustainable energy to meet future demand.

Summary: This work presents an overview of different pathways for converting forest biomass into bioenergy, including direct use, co-combustion with coal, and pelletizing. While these methods are beneficial in reducing carbon dioxide emissions, the long-term sustainability of forest biomass conversion processes should be further examined in future studies.

Summary: This study developed interpretable models using XGBoost machine learning and Shapley additive explanation to predict bio-oil yields and synergistic effects during co-pyrolysis of biomass and plastic waste. The XGBoost models achieved a prediction accuracy of nearly 0.90 R2 for bio-oil yields and greater than 0.85 R2 for synergistic effects. The findings revealed that reaction temperature and biomass-to-plastic ratio were the top two important features, but the overall contributions of feedstock characteristics exceeded 60% in the co-pyrolysis system. This provides insights into co-pyrolysis and potential pathways for improvement.
