1. 1. Circular bioeconomy through valorisation of agro-industrial residues by the edible filamentous fungus Neurospora intermedia

   Författare :Rebecca Gmoser; Mohammad J Taherzadeh; José António Teixeira; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neurospora intermedia; mycoprotein; carotenoids; feed; solid-state fermentation; circular bioeconomy; Resource Recovery; Resursåtervinning;

   Sammanfattning : Prevention of dramatic climate change and ensuring food and nutrition security for subsequent generations necessitates the reduction of greenhouse gas emissions and efficient use of the world’s resources, including efficient waste disposal. The agro-industrial sector generates a large amount of organic waste, that is currently underexploited owing to poor waste management practices. LÄS MER

3. 2. How do biogas solutions influence the sustainability of bio-based industrial systems?

   Författare :Linda Hagman; Mats Eklund; Niclas Svensson; Thomas Prade; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; biorefinery; biomass; circular bioeconomy; sustainability; feasibility; stakeholders; assessments; methods;

   Sammanfattning : 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. LÄS MER

4. 3. Biomass residues as resources : An expanded life-cycle perspective

   Författare :Johanna Olofsson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass residues; biofuels; life cycle assessment; climate change; circular bioeconomy;

   Sammanfattning : Biomass residues have been identified as potentially promising resources for production of bio-based products and fuels with low climate impacts. Unlike primary biomass such as crops, using residual biomass may avoid issues such as competition over land for food and feed production. LÄS MER

5. 4. Valorization of low-value lignocellulosic side-streams

   Författare :Daria Lebedeva; Joseph S. M. Samec; Emiel J.M. Hensen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lignocellulose; lignin; hemicellulose; hydrodeoxygenation; zeolites; furfural; catalysis; cycloaddition; biomass fractionation; pulping; Organic Chemistry; organisk kemi;

   Sammanfattning : The development of novel pathways for valorizing low-value streams from pulp, forest, and agricultural industries is crucial for realizing a circular bioeconomy and addressing the needs of both platform chemicals and fuels. Utilizing hemicellulose and lignin as biomass-derived feedstocks facilitates the production of sustainable liquid hydrocarbons, with catalytic hydrodeoxygenation being a key process. LÄS MER

7. 5. Biobased Combined Heat and Power Production in Sweden – Opportunities for and Challenges to Sustainability from the Plant Operator Perspective

   Författare :Malin Pettersson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Biobased economy; Decarbonisation; Combined heat and power plant; Sustainability;

   Sammanfattning : Although combined heat and power (CHP) production in Sweden is already largely decarbonised, this technology has further potential to alleviate pressing environmental concerns. Today, biobased CHP plants connected to district heating (DH) grids dominate the Swedish residential heating sector. LÄS MER
