1. Interactions between non-polar surfaces in water: Fokus on talc, pitch and surface roughness effects
Abstract : The aim of this thesis work was to gain understanding of the interactions between talc mineral and surfaces, liquids and chemicals relevant for industrial applications, such as pulp and paper. Talc is used in the pulp and paper industry as a filler pigment, in control of pitch (lipophilic extractives) deposits and as a coating pigment. READ MORE

2. Emulsification of Alkyl Ketene Dimer (AKD) -characterization of dispersions and emulsifiers
Abstract : Alkyl Ketene Dimer (AKD) is a commonly used hydrophobizing agent in the paper industry, introducing capillary absorption barriers for polar liquids, which makes the paper more resistant to liquid penetration. Since AKD is a so-called internal sizing agent it is usually added in the form of a water-borne dispersion. READ MORE

3. Improving properties of poly(lactic acid) biopolymer for use in food packaging
Abstract : The petroleum-based plastics are widely used for food packaging applications because of their low cost, easy processability, and tunable properties to meet the specific needs of food packaging. However, these polymers are non-biodegradable, leading to a substantial amount of plastic waste in both land and marine ecosystems. READ MORE

However, such market-based instruments are increasingly criticized for their simplistic view on complex environmental, social and economic issues; for their ethical stance; and for creating exchange value for essential ecosystems services, which potentially perpetuates a flawed economic system.

5. Protein-Based Adhesives for Particleboards
Abstract : The main objective of this study was to elucidate the possibilities to use wheat gluten (WG) as a binder for particleboards, as well as soy protein isolate (SPI). The focus was on the effect of the adhesive formulation and the processing conditions, while the press parameters were kept constant. READ MORE
