1. Biopolymers and materials from rapeseed straw biorefining
Abstract : Rapeseed straw was fractionated through a hydrothermal process into its hemicellulose, lignin and cellulose components. In the first step, hemicellulose-rich fractions were extracted. Xylan-rich fractions with high molecular weight, 30,000 – 50,000 g/mol, were obtained at 110 °C and 1.5 M NaOH. READ MORE

2. Extraction of polymeric rapeseed straw hemicelluloses for renewable films
Abstract : Polymeric hemicelluloses with high molecular weight were extracted from rapeseed straw with a straight forward hydrothermal extraction method, evaluated and refined by statistical factorial screening design and ‘severity factor’ analysis. The influence of the extraction conditions, time, temperature and pH of the extraction liquid, on the composition, molecular weight, yield and properties was unveiled. READ MORE

3. Green plasticizers for PVC - An investigation of renewable alternatives to phthalates derived from vegetable oils or wood industry products
Abstract : Polyvinyl chloride (PVC) is a very versatile thermoplastic because of its ability to solve a broad range of different concentrations of plasticizer. Phthalates are still the most commonly used plasticizer in PVC, but due to public opinion and legislation against phthalates there is a demand in the market for both old and new phthalate free plasticizersProperties of epoxidized oils of soybean (ESBO), canola (ECO), sunflower (ESFO) and safflower (ESAO) were investigated to determine their suitability as plasticizers.
