  1. 1. Possibility to reuse and recycle wood waste and CDWW

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Julia Christensen; [2023]
    Keywords : wood; wood waste; construction and demolition wood waste; recycling; reusage;

    Abstract : This essay will address if and how it is possible to reuse and recycle wood waste and CDWW (construction and demolition wood waste). The background will have a short introduction and then be divided into 3 sections. The first section addresses similarities and differences between linear vs. circular economy. READ MORE

  2. 2. Analysis of polyfunctional thiols in beer : Developing a novel method of extraction and analysis using GC-FID

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Arvid Lindmark; [2022]
    Keywords : Beer; Hops; Thiols; 3MHA; 4MMP; Food Technology; Agriculture and Food Sciences;

    Abstract : In this project, attempts were made to identify and quantify two polyfunctional thiols – 4-mercapto-4-methyl-pentanone and 3-mercaptohexyl acetate – and three monoterpene alcohols – linalool, geraniol, and β-citronellol – in beer samples. In order to avoid the use of hazardous compounds such as dichloromethane and hydroxymercuriobenzoate, common in traditional methods, two novel techniques were tested: a pure liquid-liquid extraction of the beer samples with cyclohexane, and a liquid-liquid extraction with cyclohexane followed by solid phase extraction on silver ion columns.
