    摘要： Process for the production of an organic acid from a lignocellulosic feedstock. The process is integrated with a pulp mill and comprises: a) pre-treating a lignocellulosic feedstock with an alkaline liquor from the pulp, thereby obtaining a pretreated cellulosic feed and a black liquor; b) subjecting the pretreated cellulosic feed from step a) to enzymatic hydrolysis, thereby obtaining a saccharide feed; c) subjecting the saccharide feed from step b) to microbial fermentation using calcium oxide from the pulp mill as a neutralising agent, thereby obtaining an organic acid calcium salt; d) treating the organic acid calcium salt with sulfuric acid, thereby obtaining the organic acid; e) optionally isolating lignin from the black liquor obtained in step a), thereby obtaining lignin and weak black liquor; and f) returning the black liquor from step a) and/or the weak black liquor from step e) to the pulp mill chemical recovery process.

    摘要： The present invention relates to a method of producing a nanofibrillated cellulose (NFC), the nanofibrillated cellulose product obtained and the use of the nanofibrillated cellulose product. The method comprises the steps of: Providing cellulosic fibres dispersed in water; Solvent-exchanging water in the fibres to an organic solvent, such as alcohol, suitably ethanol or isopropanol; Impregnating the fibres with a solution comprising a halogenated aliphatic acid having more than 2 carbon atoms; Heat-treating the impregnated fibres at a temperature of more than 50° C. in an alkaline solution comprising an organic solvent, which solution is optionally aqueous, to carboxyalkylatethe fibres; Washing the fibres; Converting the carboxyl groups their alkali metal counter-ion form; Optionally filtering the fibres; Dispersing the fibres in water; Mechanically disintegrating the fibres to provide the NFC product.

    摘要： A method of preparing a composition comprising mycelium along with a cellulose and/or plurality of nanoparticles is described herein. The method comprises inoculating a liquid medium with fungus, the liquid medium comprising nutrients and the cellulose and/or nanoparticles. Further described herein are compositions comprising mycelium along with a cellulose and/or plurality of nanoparticles, as well as articles-of-manufacture comprising such a composition, wherein at least 10% of the cellulose and/or nanoparticles in the composition is incorporated within the mycelium. A method of enhancing fungal growth is also described, comprising contacting the fungus with a liquid medium comprising a polymer which comprises carboxylic acid groups.

    摘要： The present invention relates to lignin-containing compositions comprising: 0 to 50 percent by weight of lignin; 0 to 50 percent by weight of a liquid C2-C4polyol; and 10 to 50 percent by weight of an acrylic resin; wherein the percentages by weight are expressed relative to the total dry weight of the composition, and wherein the total dry weight of the composition amounts to 100 percent. The present invention further relates to processes for sealing joints or coating surfaces using such a composition. Moreover, the present invention relates to joints sealed and surfaces coated using such a composition, as well as vehicles comprising such sealed joints and coated surfaces.

    摘要： The present invention relates to a method of producing lignin with reduced amount of odorous substances comprising the steps of: i) dissolving isolated lignin into an alkali solution; ii) adding to the solution C1-C4-alcohol in an amount of less than 30% by weight, based on the dry weight of the isolated lignin; and iii) re-precipitating lignin by acidifying the solution. The invention also relates to a lignin product with reduced odor obtained and/or obtainable by the method and to the use of the obtained lignin as a component in polymer blends, an additive or filler in building materials, as binding agent in adhesives, and/or for the production of a carbon fiber, especially in indoor applications.
