  • Biomass-to-Ethylene: A techno-economic perspective on multiple feedstocks
    José Caraballo-Bello, José Luis Rodríguez-Lugo, Domingo Cabrera-Gallardo, Francisco M. Baena-Moreno, Fernando Vidal-Barrero
    Biomass and Bioenergy, 2026
    This paper focuses on the synthesis of ethylene from various biomass feedstocks, with ethanol as a transitional chemical platform. Four different production routes are investigated: two first-generation pathways using sugarcane and cereal crops (e.g., corn), and 2 s-generation alternatives based on lignocellulosic materials (e.g., corn stover, wheat straw). An analysis orientated to technological performance and economic feasibility comparison is established in depth. The reference facility is modelled with an annual output of approximately 117,000t of ethylene, which would be suitable for industrial-scale deployment. The project results include material and energy balances, along with a financial evaluation using metrics such as the Net Present Value (NPV) and the Minimum Ethylene Selling Price (MESP). Among all scenarios addressed, no route initially emerges as an economically viable option under current assumptions. However, it can be stated that the sugar-based ethylene production pathway reaches the best economic results, producing an NPV of -€173M€ at current ethylene prices and an MESP of €1265/t of ethylene. The remaining pathways require cost reductions (i.e., reducing biomass purchasing cost, maintenance and overhead, and consumptions) to achieve profitability. Sensitivity analyses state the significant influence of biomass procurement costs and market price fluctuations on economic outcomes. Overall, the findings of this research underscore the promise of bioethylene as a value-added chemical, supporting broader efforts toward decarbonization. • An economic analysis of ethylene synthesis from various feedstocks is presented. • Sugar-based ethylene production path has a net present value of -€173M€. • For this path, the minimum ethylene selling price needed is €1265/t of ethylene. • The cost of biomass is the highest one in all he paths 36 %–59 % of the share.
  • A review of recent advances on the path towards a greener methanol industry

    Gas Science and Engineering, 2026
    Methanol, traditionally synthesized through natural gas and coal gasification, is studied as a versatile energy carrier with applications in transport and industrial sectors. Green methanol production has already been acknowledged to play a pivotal role in future energy systems. Furthermore, it offers an alternative to hydrogen-centered energy strategies. However, renewable routes face economic challenges, including high electrolysis costs, energy-intensive CO 2 capture, and overall system inefficiencies. This review comprehensively examines the methanol production routes, detailing plant configurations, recent technological advancements, optimal operating conditions, techno-economic analysis and life cycle assessments. We found that methanol selling prize is approximately 100-300 €/t for fossil methanol, 350-1,050 €/t for biomethanol, and 500-950 €/t for e-methanol. This significant cost gap is because carbon emissions are not currently reflected in market prices. Regarding environmental analysis, methanol from green and renewable sources has less impacts considering cradle-to-gate emissions than fossil methanol. Overall, the study provides actionable insights to advance green methanol viability in a decarbonized economy. • Methanol production routes and plant configurations are reviewed. • Technological advances and optimal operating conditions are discussed. • Economic needs for scalable biomethanol and e-methanol production are addressed. • This review provides actionable insights to advance in the methanol industry.
  • Evaluation of Spent Catalyst from Fluid Catalytic Cracking in Fly Ash and Blast Furnace Slag Based Alkali Activated Materials

    Recycling, 2025
    The objective of this work is to evaluate how spent catalyst from fluid catalytic cracking (SCFCC) affects the physical, mechanical and durability properties of fly ash (FA) and blast furnace slag (BFS)-based alkali-activated materials (AAMs). Recycling of SCFCC by integrating it in a AAM matrix offers several advantages: valorization of the material, reducing its disposal in landfills and the landfill cost, and minimizing the environmental impact. Mineralogical, physical and mechanical characterization were carried out. The durability of the specimens was studied by performing acid attack and thermal stability tests. Mass variation, compressive strength and porosity parameters were determined to assess the durability. BFS- and FA-based AAMs have a different chemical composition, which contribute to variations in microstructure and physical and mechanical properties. Acid neutralization capacity was also determined to analyse the acid attack results. Porosity, including the pore size distribution, and the acid neutralization capacity are crucial in explaining the resistance of the AAMs to sulfuric acid attack and thermal degradation. Herein, a novel route was explored, the use of SCFCC to enhance the durability of AAMs under harsh operating conditions since results show that the compositions containing SCFCC showed lower strength decay due to the lower macroporosity proportions in these compositions.
