“…Industrially, glycerol is obtained as a by-product of fat hydrolysis, ethanol fermentation and biodiesel production process (Agarwal, 1990 production from glycerol and potato juice has revealed that the fermentation route leads to less carbon dioxide emissions compared to the fossil-based route (Oxo-synthesis), however the energy requirement is higher (Ekman and Börjesson, 2011).…”

“…Upcycling by-products can increase profit as the quantities handled are large, leading to improved competitiveness and economic benefits (Cesaro and Belgiorno, 2015). This is made possible because biogas solutions are versatile treatment methods which can handle wet or dry substrates with different contents in a cost-efficient way (Ekman and Börjesson, 2011;Mountraki et al, 2016).…”

Biomass is a valuable and limited resource that should be used efficiently. The potential of replacing fossil-based products with bio-based ones produced in biobased industrial systems is huge. One important aim of increasing the share of biobased products is to improve the sustainability of systems for production and consumption. Therefore, it is important to evaluate what solutions are available to improve the sustainability performance of bio-based industrial systems, and if they also bring negative impacts. The thesis focuses on assessing the role of biogas solutions in developing sustainable bio-based systems. Such assessments are often quite narrow in their scope and focus on quantitative environmental or economic aspects. This thesis aims at also including feasibility related aspects involving the contextual conditions that are assessed more qualitatively. Biogas solutions are identified as a versatile approach to treat organic materials which are generated in large volumes in bio-based industrial systems. The results show that biogas solutions in bio-based industrial systems (i) improve circular flows of energy and nutrients, (ii) are especially viable alternatives when the quality of the by-product streams become poorer, and (iii) may improve the profitability of the bio-based industrial system. To perform better assessments of these systems, it seems valuable to broaden the set of indicators assessed and include feasibility-related indicators, preferably through the involvement of relevant stakeholders as they contribute with different perspectives and can identify aspects that influence the sustainability in different areas. Future studies could benefit from applying those broader assessments on more cases to build on a more generalisable knowledge base.

“…Quercetin, a well-defined molecular product, is an antioxidant identified as potentially extractable from onion by-products, available in large amounts around the world (Murakami et al, 2008) [34]. Today, the use of onion waste is limited to compost, animal feed, or raw material in biogas-production (Ekman and Börjesson, 2011) [35]. The goal is to add value by implementing a sustainable method to first obtain quercetin and then facilitate further use of the remaining waste for biogas production by anaerobic digestion.…”

Countries and regions around the world face a number of economic, environmental and social challenges. Increased demand for energy, primary resources (agricultural, forestry and fishing), industrial products and services (healthcare in particular) put significant pressure on the sustainability of the ecosystems that support our society. One option to provide a more sustainable base for the economy would be the transition towards bioeconomy in which the importance of biotechnology and biomassbased production to generate economic output is significantly greater than today. Bioeconomy is considered to encompass all economic activity connected with the utilization of renewable biological resources. The aim of this paper is to draw attention to the importance of bioeconomy in the management of natural resources in the 21st century, providing many answers to resolve the previous challenges together with environmental preservation. The concept has gained scientific and political attention during the recent years, especially in Europe but also globally. From the review and analysis of the literature, this paper addresses the emerging bioeconomy, definitions and conceptual bases, and its great potential in different sectors of economic activity and development of new products. Special emphasis is placed on the case of the European Union. We present the concerns of European authorities at this level and best practices already in force in two Nordic countries that can be regarded as the beginning of a general transition to bioeconomy.
