Special Issue Information

Dear Colleagues,

On June 5–8 2023 in Bologna, Italy, the 31st European Biomass Conference and Exhibition Conference (EUBCE) was held live and face-to-face for the first time following the severe disruption caused by Coronavirus in 2020, 2021, and 2022. We all enjoyed sharing the time together in the real world.

EUBCE is one of the world’s leading R&D conferences that is combined with an international exhibition. EUBCE represents the leading platform for the collection, exchange, and dissemination of scientific knowledge in the field of biomass and its utilization. This Special Issue of Energies will include presentations from the 31st EUBCE conference.

The 2023 conference program addressed the usual broad span of topics, including biomass production, biomass conversion to bioliquids and biofuels for heat and electricity, transport, and bio-based products, and it covered all aspects ranging from supply and logistics to conversion technologies, from the industrial application of research results to the impacts of biomass utilization on the environment, as well as market and trade and policy strategies, and last but not least, the role of biomass as a source in integrated energy systems.

In recent years, EUBCE also expanded its scope from biomass resources and conversion to include bioenergy and intermediate bioenergy carriers and their integration into the bioeconomy, the exploration of the role of agriculture in bioenergy production for energy and bioeconomy transition, and the improvement of citizen awareness and engagement in support of biomass technologies.

In addition, EUBCE further expanded the links between research achievements and the exploitation of innovations in scaled-up demonstration projects and the full industrialisation of biomass utilisation. The integration of technologies is a topic that presents many challenges, and this is typified in the rapid growth of interest in biorefineries and in the valorisation of all side products from biomass conversion processes and side streams that, in the past, may have been considered as wastes.

The topics to be covered in this Special Issue include, but are not limited to, the following areas:

  • Biomass feedstocks;
  • Agriculture;
  • Forestry; 
  • Organic waste; 
  • Bioenergy;
  • Energy carriers; 
  • Biofuels; 
  • Bio-based products;
  • Biorefinery; 
  • Bioeconomy; 
  • Climate change; 
  • Sustainability; 
  • Impacts.

The submission of high-quality papers in the aforementioned areas is highly encouraged. Please note each paper should contain about 50% additional/new content compared to the contents of papers submitted for the EUBCE conference proceedings.

Lignocellulosic biomass valorisation presents a promising avenue for sustainable and renewable energy production. In this study, the synergistic potential of coupling steam explosion (SE) treatment with anaerobic digestion (AD) was explored to maximize the efficient conversion of lignocellulosic biomass into valuable biogas. The SE process, a cost-effective technique for biomass fractionation, plays a pivotal role in breaking down complex biomass components, rendering them more amenable to subsequent biological treatments. In the present work, we investigated the impact of various SE conditions, including temperature, time, and acid concentration, on the breakdown of lignocellulosic residues. Through the quantification and analysis of sugars and their degradation products, the optimization of steam explosion conditions at lower temperatures and shorter time periods, along with the presence of a lower concentration of acid catalysts, efficiently releases sugars. Maintaining these conditions helps prevent byproducts. The evaluation of the (S/I)vs ratio during anaerobic digestion reveals an optimal 1/2 ratio, maximizing biogas production. This innovative approach demonstrates significant potential for the valorisation of lignocellulosic biomass, contributing to a more sustainable and efficient utilization of renewable resources in the pursuit of clean energy solutions.

Cement production is an energy- and resource-intensive industry accounting for approximately 7% of global carbon dioxide emissions. Therefore, a key decarbonisation option for the cement industry is to substitute the clinker with so-called supplementary cementitious materials (SCMs). Due to its properties and availability, the bottom ash from the biomass combustion process could be suitable as an SCM. Several agricultural residues were collected and analysed. The materials were applied for ashing experiments in a lab-scale muffle furnace, which was operated at different temperatures. The chemical, physical, and mineralogical characterisation of the ashes produced was carried out. In addition, the reactivity of the cementitious paste made from the ashes was measured through lab-scale experiments. The influence of the different ashing temperatures and the additive mixing on the properties of the ashes and cementitious paste was analysed. The results show that the spelt husk ash is the most promising biomass ash, with its high silica content and high pozzolanic reactivity. The bound water of the cementitious paste made from spelt husk ash reaches 7.3 g/100 g paste at 700 °C but decreases to 2.5 g/100 g paste at 900 °C due to the formation of a crystalline structure. Nevertheless, the addition of kaolin to the spelt husk can maintain the reactivity of the spelt husk ash produced at high ashing temperatures by stabilising the amorphous structure in the ash.

Seaweed is of importance to the environment due to properties such as its CO2 sequestration capability. On the other hand, plastic is a versatile material important to society. Unfortunately, the abundance of both plastics and seaweed represents a challenge due to the need of adequate waste management. At first, algae and plastics might not appear suitable for energy recovery; however, with co-gasification, the results are promising. This work presents a model to simulate the co-gasification of Chlorella vulgaris, Sargassum fluitans, and Sargassum natans with plastics. The effect of the gasification temperature (650–850 °C), equivalence ratio (0.25–0.45), and plastics/biomass ratio (0.0–1.0) on the produced gas’s lower heating value, tar concentration, and composition is assessed. Moreover, the environmental performance of using plastic to enhance the syngas produced from the co-gasification with sargassum is assessed using the life cycle assessment methodology. The results indicate that the lower heating value increases with the temperature and plastics/biomass ratio. Moreover, tar increases with the quantity of plastics, varying between 20 and 50 g/Nm3. Finally, adding plastics to algae during gasification reduces the variability in the syngas composition, simplifying the post-processing stage. With respect to environmental performance, gasification has an impact similar to those of pyrolysis and recycling, but the performance could improve with sufficient research and development.
