Abstract
This special issue covers three important fields of the bioeconomy: sustainable biogas value chains, bio‐based products from lignocellulose, and the use of microalgae as a biomass resource and for the production of food and feed. In order to develop sustainable products and processes, an interdisciplinary systemic approach to the analysis of entire value chains is necessary. For this reason, the contributions cover aspects of the complete biobased value chain from biomass production, pretreatment, and conversion, through to the manufacture and marketing of biobased products, and in addition, include socio‐economic and ecological assessments.
Highlights
According to the Global Bioeconomy Summit 2018 (GBS2018), the “bioeconomy” is defined as “the production, utilization and conservation of biological resources, including related knowledge, science, technology and innovation, to provide information, products, processes and services across all economic sectors aiming towards a sustainable economy”
Lewandowski, Hartung and Kiesel (2019b) show that ensiling miscanthus biomass is possible and that the specific methane yield can be improved by green harvesting in October. Another advantage of miscanthus over maize is its ability to grow on land with biophysical constraints to food crop production. This is shown in the contribution of Wagner et al (2019), who performed a Life‐Cycle Cost Assessment (LCCA) of biogas production from miscanthus grown on marginal land
The results clearly show that the use of marginal land for the cultivation of miscanthus as a substrate for biogas production can be reasonable from an economic and environmental perspective
