The decrease and unreasonable utilization of petroleum derivatives and the effect of greenhouse gases on nature are driving exploration into sustainable power source development from natural assets and waste. The worldwide vitality request is high, and a large portion of this energy is developed from fossil fuels. Recent investigations report that Anaerobic Digestion (AD) is a proficient option innovation that joins bio-fuel yield with reasonable waste administration; and, different mechanical patterns exist in the biogas business which upgrades the generation and nature of biogas. Profound interests in AD are relied upon to meet with the expanding accomplishments because of the minimal effort of accessible nourish stocks and the extensive variety of employments for biogas (i.e., for warming, power and fuel). Biogas formation is urged in numerous countries to build up the commercial market and offers a conservative option for bio-energy generation. In India, many States are empowering their kin and supporting them financially to build bio plants. The goal of this paper is to give a review of biogas plants, sorts of waste used to deliver biogas, approaches to produce biogas and issues in the biogas generation.

“…The results confirmed that the volatile material and cellulose content significantly influenced the bio-oil yield, which can be used as fuel in boilers and diesel engines for power generation as a substitute for fossil fuels. Hawash et al, 9 studied the pyrolysis of seven different agricultural residues in a tubular furnace reactor at 500 °C for 15 min. The produced bio-oil and biochar were studied with the purpose of determining their chemical composition and quality.…”

The use of agricultural residues for the production of bio-oil is an important alternative to the use of fossil fuels. In this study, the Caupi bean pod (Vigna unguiculata) was characterized and used as biomass in the production of bio-oil. This biomass was evaluated in terms of physicochemical, morphological (scanning electron microscopy (SEM)), and thermal (thermogravimetric analysis (TGA), differential scanning calorimetry (DSC)) characterization, lignocellulosic composition, and pyrolysis processes. The pyrolysis was carried out in a stainless steel fixed-bed reactor (260 mm in length and 60 mm in diameter) under atmospheric nitrogen pressure. Pyrolysis was conducted at 550, 600, and 700 °C and N 2 gas flow of 2, 5, and 7 mL min-1. The chemical composition of the bio-oils was studied through CHN, TGA, Fourier-transform infrared spectroscopy (FTIR), and gas chromatography-mass spectrometry (GC-MS). The results confirmed the bean pod's potential in the thermochemical process. The thermogravimetric analyses demonstrate that there can be a relationship between the components of the principal biomass (cellulose, hemicellulose, and lignin) and the compounds present in the bio-oil. The obtained bio-oils represent bio-products that are rich in compounds of several chemical classes with relevant commercial value such as acids (palmitic, linoleic, oleic, and stearic), alcohols (ethylene glycol), sugars (levoglucosan), and phenols (guaiacol, catechol, phenol, and pyrocatechol).

“…Researchers have been evaluating the utilisation of biomass from agricultural and animal wastes as a renewable source for fuels and chemicals due to its favourable properties in terms of potential energy. [1][2][3][4][5] Biochemical, physiochemical and thermochemical processes are used for this purpose, with the dominance on the latter method because of its effectiveness in the thermal decomposition of biomass to volatiles and char products. 6 The most developed thermochemical techniques are pyrolysis, gasification and combustion.…”

The characteristics and kinetics of durian shell (DS) pyrolysis were investigated using non-isothermal thermogravimetric analysis (TGA). DS is a celluloserich biomass with high volatile matters content, which is suitable for bio-oil production. Thermal decomposition experiments were performed under nitrogen flow at various heating rates (i.e., 5°C min -1 , 10°C min -1 and 20°C min -1 ). The model-fitting method represented by Coats-Redfern was applied on the experimental TGA data of DS pyrolysis. The decomposition of DS was divided into three stages: first stage (59°C-200°C) involved removal of moisture and light volatiles; second stage (200°C-400°C) showed decomposition of cellulose and hemicellulose; and third stage (above 400°C) presented lignin decomposition. There was 56% weight loss observed in second stage, revealing that decomposition of cellulose and hemicellulose contributed the most on volatile production. The model shows that the activation energy was between 42.08 kJ mol -1 and 84.40 kJ mol -1 for the second stage of the pyrolytic process from 200°C to 400°C using different decomposition mechanisms. The Coats-Redfern method is applied successfully for the correlation of experimental TGA data with an average correlation coefficient (R 2 ) of 0.991 while one-way diffusion model D1 gave the highest correlation coefficient of 0.998. DS biomass is a suitable raw material for energy or chemicals production.
