Stability of the Lignins and their Potential in Production of Bioplastics

Abstract:

Chemical industry includes a biobased materials (sector) in which some oil-derived plastics and chemicals are replaced by new or alternative products derived, at least partially, from biomass. One of these biobased products is here today - lignin, but to fulfil its societal potential it is necessary to improve their market share while making valuable contributions to climate change mitigation. Great source of lignin is by-product (waste) from paper making industry. Lignin isolated from black liquors has a big potential to be used as a component for new bioplastic compositions. Lignosulphonates and lignin are polydispersions of different large fragments from natural tree dimensional lignin present in the wood. The kraft lignin consists of large amount of sulphur which is bonded in functional groups. Content of lignin in black liquor is in range 30 - 45% what brings potential of its isolation. In this paper we characterised and precipitated lignin with two inorganic and one organic acid (nitric, hydrochloric and tartaric acid).
