“…However, the unrestricted use of fossil fuels leads to environmental impacts and resource depletion, driven by industrialization and population growth (Saravanan et al 2023). Currently, around 80% of global energy network depends on non-renewable resources (Ruiz et al 2023). There is a latent need towards the energy transition using clean and renewable sources (Amalina et al 2022).…”

The evaluation of lignocellulosic biomass applied to thermochemical routes is postulated as an alternative for the generation of energy from renewable sources. This work aims to compare biorefineries based on two thermochemical routes for the use of raw materials from the rice (husk and straw) production chain in the Department of Sucre-Colombia. Initially, this work analyzes the physicochemical and structural characterization of biomass. Four different scenarios are proposed for the comparison of the valorization from the simulation in Aspen Plus by means of fast pyrolysis and downdraft gasification. The novelty of this work is focused on the identification of the biorefinery with the best techno-economic, energetic, and environmental performance for the generation of electricity and value-added products from rice straw and husk. From an economic perspective, the stand-alone gasification process does not have a positive economic margin, which is an opposite behavior from the pyrolysis process. The biorefinery proposed in scenario 1 (fast pyrolysis of both rice residues) had the best economic and environmental performance with an economic margin of 13.75% and emissions of 2170.92 kgCO2eq/kg for 10 years. However, this scenario was not energetically the best, holding second place due to the feedstock requirements, compared to gasification. The biorefinery scenario 1 has the best performance.

Despite the increasing global need for sustainable energy, biomass gasification is becoming a highly promising method for transforming raw biomass into usable energy. The present review article analyzes the essential aspects of biomass‐based energy production, starting with an assessment of existing energy needs and the crucial contribution that biomass can make in fulfilling these demands. The research investigates recent advancements in several biomass gasification methods, explaining their mechanics and discussing the related difficulties. The research conducts a thorough evaluation of the efficiency, yield, and environmental consequences of biomass gasification, aiming to determine the feasibility of the technique. In addition, the study rigorously assesses the techno‐economic factors of energy generation from biomass, providing valuable information on the economic viability and scalability of various biomass gasification techniques. The present study is focused on providing a comprehensive understanding of biomass gasification by analyzing current improvements and conducting a techno‐economic comparison to make well‐informed decisions for a sustainable energy future.
