Abstract

Thermochemical conversion processes convert biomass into gaseous, liquid and solid products named, syngas, bio-oil and char, respectively. Syngas and bio-oil are considered as alternative biofuels to fossil fuels and wide investigations are implemented currently on their production, purification, modification, and applications. Biomass chars have receiving an increasing attention since they lead to carbon sequestration, reduction of the amount of carbon rejected into the atmosphere and represent an friendly carbon source for numerous applications. In particular, biomass chars could be an efficient materials for energy production, syngas production and upgrading, water and air pollutants removal, soil amendment, fuel cells and supercapacitors development, and gas storage. Improving the knowledge of biomass chars elaboration techniques such as pyrolysis, gasification and hydrothermal carbonization is essential to determine the optimal production strategies for their economic viability. Furthermore, the characterization of the physicochemical, textural, structural and surface chemistry properties of the derived chars guide the selection of the suitable recovery processes in order to maximize their utility and therefore the benefits for the environment as well as for industries and agriculture.

Abstract

Carotenoids are a group of natural pigments, consisting of more than 750 compounds. They are mostly yellow, orange, or red in color, due to the system of conjugated double bonds. This structural element is also responsible for the good antioxidant properties of many carotenoids. Carotenoids have shown numerous biological activities (not only as provitamin A), e.g., preventive properties of fruits and vegetables. As lipophilic compounds, their uptake and storage in the body are dependent on various conditions. In vitro and in vivo data showed stimulating and inhibitory effects of matrix compounds on bioaccessibility and bioavailability of carotenoids.

Abstract

The bioeconomy concept aims to add sustainability to the production, transformation, and trade of biological goods. Though implemented around the world, the development of national bioeconomies is uneven, especially in the global South, where major challenges exist in Sub-Saharan Africa. In this context, the international BiomassWeb project aimed to underpin the bioeconomy concept by applying the value web approach, which seeks to uncover complex interlinked value webs instead of linear value chains. The project also aimed to develop intervention options to strengthen and optimize the synergies and trade-offs among different value chains. The Special Issue “Advances in Food and Non-Food Biomass Production, Processing and Use in Sub-Saharan Africa: Toward a Basis for a Regional Bioeconomy"" compiles 23 articles produced in this framework. The articles are grouped in four sections: the value web approach; the production side; processing, transformation and trade; and global views.
