1. Anaerobic digestion in the kraft pulp and paper industry : Challenges and possibilities for implementation
Sammanfattning : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.

2. The Problem with Errors : Solution Search in Platform Development
Sammanfattning : This dissertation is concerned with problem-solving in platform development. A problem isconceived of as an obstacle that needs to be overcome in order to reach a desired outcome,whereas a solution is denoted by the set of activities required to reach such an outcome. LÄS MER
3. Functional Degradable Polymers by a Radical Chemistry approach
Sammanfattning : One class of polymers that is inherently of great value for many applications is the aliphatic polyesters. Such polymers are very suitable for use as temporary guides, scaffolds, for tissue formation and other biomedical applications, due to their biocompatibility, degradability and appropriate mechanical properties.

4. Renewable Energy and Nutrient Valorization from Anaerobic Digestion : Resource-Efficient Solutions
Sammanfattning : This thesis presents a comprehensive analysis aimed at understanding process performance, methane yield, and key influencing factors within the context of solid-state anaerobic digestion (SS-AD). SS-AD is used to treat organic material with high solids content, which can be challenging to address by alternative methods. LÄS MER
5. Non-linear mechanics of nanocellulose foams
Sammanfattning : There has been a growing interest in nano-fibrillar cellulose (NFC), which has been fuelled not merely by the advantages it presents in terms of strength to weight ratio and biodegradability, but also owing to the recent advances in production techniques. NFC foam is essentially a hierarchical structure, wherein nanofibrils account for the smallest scale, with the pores/cell walls forming the meso scale. LÄS MER
