1. Recovery of Hemicelluloses Extracted from Spruce and Wheat Bran : Membrane Filtration Process Development and Cost Estimates
Abstract : Hemicelluloses are a group of abundant polymers found in all plants and constitute about one third of the total plant biomass. These polymers can be used in many different products, such as oxygen barrier films, emulsifiers, foams and probiotic food additives. READ MORE

2. Physicochemical Treatment of Municipal Wastewater : From Direct Membrane Filtration to Adsorption of Organic Micropollutants
Abstract : Pharmaceutical residues and other organic micropollutants are transported via municipal wastewater to wastewater treatment plants (WWTPs). However, current treatment processes are not designed to remove organic micropollutants, and several such compounds have been found in recipients, where they can have negative effects on aquatic organisms.

3. Hemicelluloses from Agricultural and Forestry Crops Isolation, Characterisation, and Enzymatic Hydrolysis
Abstract : Hemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. READ MORE

4. Downstream Processing Using Membrane Technology
Abstract : Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. READ MORE

5. Separation of Biomass Components by Membrane Filtration - Process Development for Hemicellulose Recovery
Abstract : One of the major challenges facing the world today is the reduction of our dependency on fossil resources as their exploitation has severe negative effects on the environment. One way of realizing this is to utilise the components of lignocellulosic biomass to a greater extent as feedstock for various industrial products. READ MORE
