Summary: The careless usage of fossil fuels is the primary contributor to global warming. Due to urbanization's threat to resource depletion, finding alternatives has become necessary. Four different forms of biofuels are now available as possible replacements, including first-generation biofuels from the edible portion of biomass, second-generation biofuels from the non-edible portion, third-generation biofuels from algal biomass, and fourth-generation biofuels using molecular biology to improve algal strains. This article discusses the importance of second-generation biofuels derived from non-edible biomass and the enzymes involved in their production.

Summary: This study compared the pyrolysis products of eight different feedstocks in arid regions, including food waste, biosolids, segregated fruits and vegetable waste, animal manure, date palm waste, and halophyte plant. Food waste, Salicornia bigelovii seed, and undigested sludge had the highest bio-oil yield. Bio-oils from food waste and Salicornia bigelovii seed were rich in acidic compounds. Animal manure and biosolids had the lowest calorific value for biochar production. Digested biosolid had high calorific value in gas production. Food waste was identified as the most promising feedstock due to its superior bio-oil quality and abundant availability.

Summary: The transition from gasoline and petroleum-based products to biofuels and green chemicals is a paradigm shift that will lead to the development of the bioeconomy. Biorefineries in countries like Brazil play a crucial role in this transition, with the country generating a significant amount of second-generation biomass and having an attractive consumer market. Technological innovations are still needed to fully unlock the potential of biomass conversion to biofuels and biochemicals, but successful examples such as renewable products for cosmetics and sustainable technologies for pulp production already exist. The RenovaBio Policy launched by the Federal Brazilian Government aims to boost the production and utilization of biofuels and green chemicals in the country.

Summary: The study investigated the impact of second-generation biofuels, specifically BBuE, on exhaust gas composition from a diesel engine. Results showed that by powering the engine with BBuE, lower concentrations of carbon monoxide, carbon dioxide, hydrocarbons, particulate matter, and nitrogen oxides were achieved compared to using first-generation biofuel RME or diesel fuel DF. This suggests that new-generation biofuels emit fewer undesirable exhaust gas components into the atmosphere.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
