1. Pyrolysis of mixed plastics and paper to produce fuels and other chemicals
Abstract : As the world population and economy grow, higher consumption results in higher waste packaging, plastics and paper residues. Pyrolysis offers a way to recover fuels and other chemicals from this waste fraction. READ MORE

2. On the multifunctional performance of structural batteries
Abstract : The structural battery composite is a composite material that can store electrical energy (i.e. work as a battery) while simultaneously provide mechanical integrity in a structural system. Due to its inherent ability to store energy this material offers significant weight savings on a system level. READ MORE

3. Functional Properties and Morphology of Recycled Post-consumer WEEE Thermoplastic Blends
Abstract : This work concerns a waste electrical and electronic equipment blend of recycled plastics (WEEEBR), reprocessed from a low density thermoplastics batch (600 kg) by removal of non-thermoplastic contamination (1.2 weight % (wt%)). READ MORE

4. Protein-based Packaging Films, Sheets and Composites: Process Development and Functional Properties
Abstract : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.

5. Improved Usage of Wood Raw Material through Modification of the Kraft Process
Abstract : The kraft process is a complex system with many variables, and though the process is fairly well understood, there is still much we do not know. This thesis examines some aspects of the kraft process that could prove to be of interest for the pulp and paper industry, specifically, the impact of wood chip impregnation and of the chemical structure of xylan on spruce kraft pulp.
