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 current energy scenario in India requires a transition from conventional fossil fuels to renewable fuels. Biomass-derived fuels have been found to emit fewer pollutants compared to fossil fuels, and India has significant biomass resources available for biofuel production and power generation, dominated by agricultural-based biomass. The country also has potential for bioenergy generation through municipal solid waste. This review discusses the various biomass resources in India and their potential for bioenergy generation, as well as the initiatives taken by the Indian Government in this field.

Summary: This study evaluated the use of hydrothermal liquefaction as a sustainable method to convert municipal sewage sludge into renewable energy source, biocrude. The effects of reaction temperature and residence time on biocrude yield and quality were investigated using response surface methodology. The study found that optimizing the reaction conditions resulted in maximized biocrude yield and energy recovery. The composition and quality of the biocrude were influenced by the reaction temperature. Upgrading and recovering trace metals from the biocrude were also found to be necessary. These findings contribute to the advancement of biorefinery technology and can guide the design of full-scale sludge treatment systems.

Summary: This study focuses on investigating the effect of reaction conditions, particularly the reaction atmosphere type, on the composition of volatiles generated during the pyrolysis of lignin. It was found that processing temperature has a significant impact on the composition changes of volatiles, while the pyrolysis atmosphere has minor qualitative effects but noticeable quantitative differences in their concentration. The complex molecular structure of lignin was confirmed through the identification of phenol derivatives, aliphatic oxygen compounds, and aromatic hydrocarbons as primary and secondary products of lignin decomposition.
