“…The main route of biomass into liquid fuel 'drop-in' is through the gasification process. On a small scale, woody biomass gasification outperforms combustion and pyrolysis in terms of technological and economic impacts, while pyrolysis has been identified as the best large-scale method for upgrading woody biomass (Solarte-Toro et al 2021). The biomass into liquid fuel such as bio-methanol starts with biomass gasification under low pressure using downdraft gasifier owing to its low tar formation along with long residence time (Li et al 2021).…”

The global energy demand is projected to rise by almost 28% by 2040 compared to current levels. Biomass is a promising energy source for producing either solid or liquid fuels. Biofuels are alternatives to fossil fuels to reduce anthropogenic greenhouse gas emissions. Nonetheless, policy decisions for biofuels should be based on evidence that biofuels are produced in a sustainable manner. To this end, life cycle assessment (LCA) provides information on environmental impacts associated with biofuel production chains. Here, we review advances in biomass conversion to biofuels and their environmental impact by life cycle assessment. Processes are gasification, combustion, pyrolysis, enzymatic hydrolysis routes and fermentation. Thermochemical processes are classified into low temperature, below 300 °C, and high temperature, higher than 300 °C, i.e. gasification, combustion and pyrolysis. Pyrolysis is promising because it operates at a relatively lower temperature of up to 500 °C, compared to gasification, which operates at 800–1300 °C. We focus on 1) the drawbacks and advantages of the thermochemical and biochemical conversion routes of biomass into various fuels and the possibility of integrating these routes for better process efficiency; 2) methodological approaches and key findings from 40 LCA studies on biomass to biofuel conversion pathways published from 2019 to 2021; and 3) bibliometric trends and knowledge gaps in biomass conversion into biofuels using thermochemical and biochemical routes. The integration of hydrothermal and biochemical routes is promising for the circular economy.

“…The use of energy to oxidize residues such as biomass via gasification or combustion has a purpose to generate thermal energy and simultaneously destroy or recover possible toxic compounds under emission control [74]. There are two important sub-routes to recover energy from biomass: first, gasification that is relevant to produce CO and H 2 for Fischer-Tropsch synthesis (conversion of hydrogen and carbon monoxide into hydrocarbon products) [75], and second, combustion, which is a method of burning biomass to generate hot gasses to be used in energy generation processes [76].…”

Coupling Plant Biomass Derived from Phytoremediation of Potential Toxic-Metal-Polluted Soils to Bioenergy Production and High-Value by-Products—A Review

Phytoremediation is an attractive strategy for cleaning soils polluted with a wide spectrum of organic and inorganic toxic compounds. Among these pollutants, heavy metals have attracted global attention due to their negative effects on human health and terrestrial ecosystems. As a result of this, numerous studies have been carried out to elucidate the mechanisms involved in removal processes. These studies have employed many plant species that might be used for phytoremediation and the obtention of end bioproducts such as biofuels and biogas useful in combustion and heating. Phytotechnologies represent an attractive segment that is increasingly gaining attention worldwide due to their versatility, economic profitability, and environmental co-benefits such as erosion control and soil quality and functionality improvement. In this review, the process of valorizing biomass from phytoremediation is described; in addition, relevant experiments where polluted biomass is used as feedstock or bioenergy is produced via thermo- and biochemical conversion are analyzed. Besides, pretreatments of biomass to increase yields and treatments to control the transfer of metals to the environment are also mentioned. Finally, aspects related to the feasibility, benefits, risks, and gaps of converting toxic-metal-polluted biomass are discussed.

“…In fact, modelling is a mathematical methodology that allows for the following: assessing the performance of pyrolysis; investigating the possibilities of optimizing their performance in order to achieve desired product yields and distribution; saving time and money, particularly for full-scale processes; and forecasting and studying biomass thermal breakdown and studying the influence of different operating conditions. The different elements of equilibrium and kinetics models of the thermochemical process have been explored numerically (Baruah and Baruah 2014;Sharma et al 2015;Solarte-Toro et al 2021). The non-isothermal TG/DTG experimental results of the pyrolysis of the studied sample olive pomace at 5, 10 and 20°C/min in an inert environment were used for kinetic modelling Figure 4.…”

This work demonstrates, experimentally and numerically, the potential of Olive Pomace Waste (OPW) to produce renewable biofuels (pyrolytic oil and gas), bio-chemicals (tars as source of bioactive molecules) and bio-fertilizers (chars) through slow pyrolysis. Experimental pyrolysis runs were conducted at 500, 600 and 700°C as final pyrolysis temperature, 15, 20 and 25°C/min as heating rate and 1h as residence time, in a fixed bed pyrolyzer. In the optimum pyrolysis conditions (600°C and 15°C/min), 33 wt.% of oil, 30.00 wt.% of char and 37 wt.% of gas were produced. Recovered pyrolytic oil presents good energy value (HHV between 15.96 and 20.94 MJ/kg) with a great bioactive potential. The released permanent gases show an interesting energy content (LHV up to 11 MJ/Kg) which emphasizes their application in a gas engine to provide renewable electricity in rural olive groves area. The recovered OPW biochar presents a high carbon (C 72.54 wt.%) and nutrients contents (up to 8.42 mg/g of Ca, up to 8.69 mg/g of K and up to 2.02 % of total N) which make it suitable for soil amendment and for long-term carbon sequestration. Kinetic study of OPW pyrolysis, performed using the Distributed Activation Energy Model (DAEM), gives an activation energy values ranging from 121.6 to 151.6 kJ/mol. The investigation of the OPW thermal behavior and reactivity under pyrolysis conditions is useful approach to design and operate slow pyrolysis process at commercial scale, which could be useful by farmers for OPW in olive fields.
