“…Nevertheless, since small iron particles are pyrophoric, the formation of oxide can be the result of oxidation of the metal nanoparticles reduced under reaction conditions, but this is only a tentative hypothesis and was not proved here. The formation of metallic phases is in accordance with the literature data, for example, [ 51 ]. Pure SCB was additionally tested in gasification under the same conditions, and it was found that, presumably, the phase of calcium phosphate Ca 2 P 2 O 7 (the ICDD card number [9-346]) is present in the sample.…”

“…The main efforts in catalytic processes development in the carbon wastes utilisation are focused on the following groups: alkali metals (for example, [ 24 , 25 , 26 , 27 , 28 , 29 ]), alkali–earth metals [ 30 , 31 , 32 ], and transition metals [ 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ]. Different natural and synthetic materials have been tested as carriers for the catalyst for carbon waste utilisation, for example, dolomite [ 44 ], olivine [ 45 , 46 ], or MgO [ 47 ], etc., but the main research is focused on the systems with metals directly deposited on the gasified (or pyrolyzed) material such as rice husk, etc., for example [ 48 , 49 , 50 , 51 ]. SiO 2 and Al 2 O 3 can affect the catalytic behaviour as well [ 52 ].…”

To meet the increasing needs of fuels, especially non-fossil fuels, the production of “bio-oil” is proposed and many efforts have been undertaken to find effective ways to transform bio-wastes into valuable substances to obtain the fuels and simultaneously reduce carbon wastes, including CO2. This work is devoted to the gasification of sugar cane bagasse to produce CO in the process assisted by CO2. The metals were varied (Fe, Co, or Ni), along with their amounts, in order to find the optimal catalyst composition. The materials were investigated by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), X-ray diffraction (XRD), and electron diffraction, and were tested in the process of CO2-assisted gasification. The catalysts based on Co and Ni demonstrate the best activity among the investigated systems: the conversion of CO2 reached 88% at ~800 °C (vs. 20% for the pure sugarcane bagasse). These samples contain metallic Co or Ni, while Fe is in oxide form.

“…The findings showed that the high ash concentration of macroalgae caused poorer bio-oil yields when compared to the results achieved from hydrothermal liquefaction of a variety of microalgae (in the range of 26-57% dw) [292]. Although the gasification of biomass on a wide scale was successfully demonstrated, it was still comparatively costly in contrast to fossil-fuel energy [293,294]. Indeed, gasification was able to generate hydrogen and syngas at a competitive price in the market.…”

Blue carbon has made significant contributions to climate change adaptation and mitigation while assisting in achieving co-benefits such as aquaculture development and coastal restoration, winning international recognition. Climate change mitigation and co-benefits from blue carbon ecosystems are highlighted in the recent Intergovernmental Panel on Climate Change Special Report on Ocean and Cryosphere in a Changing Climate. Its diverse nature has resulted in unprecedented collaboration across disciplines, with conservationists, academics, and politicians working together to achieve common goals such as climate change mitigation and adaptation, which need proper policy regulations, funding, and multi-prong and multi-dimensional strategies to deal with. An overview of blue carbon habitats such as seagrass beds, mangrove forests, and salt marshes, the critical role of blue carbon ecosystems in mitigating plastic/micro-plastic pollution, as well as the utilization of the above-mentioned blue carbon resources for biofuel production, are critically presented in this research. It also highlights the concerns about blue carbon habitats. Identifying and addressing these issues might help preserve and enhance the ocean’s ability to store carbon and combat climate change and mitigate plastic/micro-plastic pollution. Checking out their role in carbon sequestration and how they act as the major carbon sinks of the world are integral parts of this study. In light of the global frameworks for blue carbon and the inclusion of microalgae in blue carbon, blue carbon ecosystems must be protected and restored as part of carbon stock conservation efforts and the mitigation of plastic/micro-plastic pollution. When compared to the ecosystem services offered by terrestrial ecosystems, the ecosystem services provided by coastal ecosystems, such as the sequestration of carbon, the production of biofuels, and the remediation of pollution, among other things, are enormous. The primary purpose of this research is to bring awareness to the extensive range of beneficial effects that can be traced back to ecosystems found in coastal environments.

“…Furthermore, investigations into heavy metals, metal combinations, metallic salts, oxides, acidic oxides, zeolites, and organic and inorganic salts, have provided valuable insights [ [6] , [7] , [8] , [9] , [10] , [11] , [12] ]. Notably, calcium oxide-based catalysts have shown promise in reducing tar during gasification, and the utilization of Ni-based catalysts supported on dolomite has increased H 2 production during pyrolysis/gasification of ZnCl 2 -impregnated biomass [ [13] , [14] , [15] ]. Additionally, the effect of metallic salts as catalysts in biomass pyrolysis has been studied in detail by various researchers.…”
