Abstract: According to an example aspect of the present invention, there is provided a method of capturing and analyzing of colloidal microplastics and nanoplastics from aqueous medium. More precisely, the invention relates to a method for collecting and analyzing colloidal nano- and microplastic particles from aqueous media using nanoscaled lignocellulosic structures.

Abstract: The present invention concerns a process for the conversion of biomaterials into structural carbon products, particularly utilizing a hydrothermal treatment step that is carried out on a high molar mass organic starting material having a carbon content of >40 wt % of the dry matter. The invention also concerns a structural carbon product obtained using such a process, which has well-defined physico-chemical properties, e.g. in terms of surface area, carbon content, density, size and shape.

Abstract: Provided are biomass-based materials and valuable uses of microalgal biomass including: (i) acetylation of microalgal biomass to produce a material useful in the production of thermoplastics; (ii) use of triglyceride containing microalgal biomass for production of thermoplastics; (iii) combination of microalgal biomass and at least one type of plant polymer to produce a material useful in the production of thermoplastics; (iv) anionization of microalgal biomass to form a water absorbant material; (v) cationization of microalgal biomass, and optional flocculation, to form a water absorbant material; (vi) crosslinking of anionized microalgal biomass; (vii) carbonization of microalgal biomass; and (viii) use of microalgal biomass in the making of paper.
