Utilization of Barley Straw as Feedstock for the Production of Different Energy Vectors Open
During the bioethanol production process, vast amounts of residues are generated as process waste. To extract more value from lignocellulosic biomass and improve process economics, these residues should be used as feedstock in additional p…
Characterisation of Electrochemical Sensor-Array for Utilisation in Construction of BOD Bioelectronic Tongue Open
There is need to rapidly measure biochemical oxygen demand (BOD) to estimate organic pollution in wastewater. Biosensors are able to estimate BOD values within 5–30 minutes, but they have some limitations that can be overcome with biosenso…
Biomass Pretreatment with the Szego Mill™ for Bioethanol and Biogas Production Open
Results from an investigation of the mechanical size reduction with the Szego Mill™ as a pretreatment method for lignocellulosic biomass are presented. Pretreatment is a highly expensive and energy-consuming step in lignocellulosic biomass…
The Role of Ionic Liquids in the Lignin Separation from Lignocellulosic Biomass Open
Lignin is a natural polymer, one that has an abundant and renewable resource in biomass. Due to a tendency towards the use of biochemicals, the efficient utilization of lignin has gained wide attention. The delignification of lignocellulos…
Perennial Grasses as a Substrate for Bioethanol Production Open
One of the possible choices as a biomass for lignocellulosic bioethanol production are different perennial grasses. Cultivating this type of biomass has many advantages in terms of natural diversity and landscape protection. In this study,…
The Efficiency of Nitrogen and Flue Gas as Operating Gases in Explosive Decompression Pretreatment Open
As the pretreatment process is the most expensive and energy-consuming step in the overall second generation bioethanol production process, it is vital that it is studied and optimized in order to be able to develop the most efficient prod…
Explosive Decompression Pretreatment - Nitrogen or Flue Gas? Open
Pretreatment is the most expensive and energy-consuming step in the overall second generation bioethanol production process and therefore, it is vital to study and optimize it to gain maximum glucose and ethanol yields. The aim of this pap…
INDO-NORDEN – a consortium for developing holistic processes and land use practices for clean energy Open
Intensive forest harvesting techniques are being used in Finland to enhance the share of bioenergy. However, there are no clear indications as to how environmentally safe are these practices. We address this issue in the INDO-NORDEN projec…
Second-generation bioethanol production: a review of strategies for waste valorisation. Open
This paper reviews second-generation biofuel production chain and focuses on its energetic, economic and environmental impacts. The biggest challenge in the production of bioethanol from lignocellulosic material refers to the biomass waste…
