“…The global potential of rice straws in this study that was burned was about 3.85 Mt, which could be used for heat and electricity production. In addition, Nanzhhu et al [48] analyzed the pyrolysis and the gasification process of rice straw feedstock. Grotto et al [49] studied the energy potential of rice husk biomass in Brazil.…”

The growing increase in greenhouse gases, especially carbon dioxide (CO2), by anthropogenic activities can be linked to extreme climate events, such as intensive droughts, floods, or hurricanes, and has led to several studies focused on reducing the concentration of this greenhouse gas in the atmosphere. Some technologies, such as carbon capture and storage (CCS), can potentially sequester billions of tons of CO2 per year. One of the promising methods is the use of carbon mineralization as a CCS methodology. For this approach, some minerals can be investigated, such as wollastonite, which can be obtained from agricultural waste recovery. One topic of interest in these studies is agriculture, demonstrating that it can play an important role in climate change mitigation. This work presents a critical review of the studies of rice waste use for potential synthesizing wollastonite as a path for CO2 storage, promoting the circular economy. Several works were analyzed and presented, addressing eco-friendly wollastonite use, such as in the cement industry, and they can contribute to a lower global warming potential. There is a promising way to explore, once there are few studies in the literature about CO2 capture and storage of wollastonite by carbon mineralization.

“…Gasification is the partial oxidation of biomass into syngas at elevated temperatures. Gasification technology depends on a sequence of fundamental reactions such as dehydration, pyrolysis/devolatilization, and gasification to transform the biological composition of biomass such as carbohydrates, proteins, and lipids into syngas that contains alkane hydrocarbons such as CO, H 2 , CH 4 , C m H n , etc . The conversion efficiency of gasification ranges between 70% and 90%, depending upon the parametric conditions and reactor .…”

Syngas from biomass gasification can be used in downstream process industries such as city gas, hydrogen production, etc. In this review, the effects of biomass feedstock properties, and gasification reaction conditions (temperature, gasifier type, etc.) on syngas properties are systematically reviewed. In summary, the cracking and reforming of volatile fractions in the gasification process and the catalytic effect of alkali and alkaline earth metals in the ash on the gasification have a direct impact on the syngas yield. And biomass pretreatment (i.e., terrifying/ hydrothermal carbonization) can reduce the moisture content, which can effectively reduce the energy required for gasification and enhance the calorific value and syngas yield further. The fixedbed gasifiers produce lower amounts of syngas. The concentration of H 2 is significantly increased by adding steam as a gasification agent. Additionally higher gasification temperatures produce more syngas, and an equivalence ratio of about 0.2−0.3 is considered suitable for gasification. For the influence of feedstock on syngas, this paper not only reviews the feedstock properties (volatile, ash, moisture) but also compares the influence of two pretreatments on syngas yield and proposes that the combination of torrefaction/hydrothermal carbonization and a multistage air bed gasifier is an important research direction to improve the combustible components of syngas. In addition to the summary of commonly used single gasification agents, two or more gasification agents on the concentration of syngas components are also discussed in the gasification parameters, and it is suggested that further research into the use of more than one gasification agent is also important for future syngas production.

“…Second generation biofuels from lignocellulosic feedstocks are part of a suite of solutions for peak oil utilisation and a secure climate economy (Ellem, Mulligan, 2012). The above trend persists and straw is used as fuel (Jameel, Keshwani, 2017;Ai et al, 2021;Turkyilmazoglu, 2021;Zhou, 2022;Liu, 2023). Straw is used as a weeding material, and a dry by-product with fine grains is commonly used.…”

The straw is mostly used in agriculture as fodder or bedding for livestock. It is a natural organic material, i.e. flammable. This article deals with the observation of the behaviour of straw when heat loaded to radiant heat. The aim of the article is to experimentally determine the ignition temperature of straw as a function of the time of exposure to radiant heat. At the same time, there was determination straw’s samples of the minimum ignition temperature using isothermal testing on a hot-plate according to EN 50281-2-1:1998. The influence of a selected amount of straw sample on the thermal degradation behaviour, the temperature increase inside the sample and the ignition temperature of the sample as a function of time was observed. There were identification of straw degradation processes (in temperature values °C) as a function of time: Odour, Smoke, Carbonisation of the bottom layer of the sample, Carbonisation of the edges of the sample, Ignition and burning. The value of the straw ignition temperature 380°C is sufficient for the initiation and development of fire.
