1. Waste Textiles Bioprocessing to Ethanol and Biogas
Abstract : The work of the present thesis focused on conversion of the cellulosic part of waste textiles into biogas and ethanol, and its challenges. In 2009, the global annual fiber consumption exceeded 70 Mt, of which around 40% consisted of cellulosic material. READ MORE

2. Bioethanol Production: Pretreatment and Enzymatic Hydrolysis of Softwood
Abstract : The enzymatic hydrolysis process can be used to produce bioethanol from softwood, which are the dominating raw material in the Northern hemisphere. This thesis deals with the development of the process focusing on the pretreatment and the enzymatic hydrolysis stages. READ MORE

4. Towards sustainable plastics : Microbial production of aromatic and aliphatic building blocks from biobased feedstock and plastic hydrolysate
Abstract : The current plastic system is unsustainable and needs to change. Plastics are mainly produced from fossil feedstock, contributing to greenhouse gas emissions, and low rate of post-consumer recycling results in pollution on land and in oceans with high ecological impact, and huge loss of valuable material.

5. Microbial and enzymatic syntheses of polymer building blocks through selective transformations of polyols and furans
Abstract : AbstractTransition from fossil- to bio-based economy is a critical step towards reduction of greenhouse gas emissions and climate change, and hence for achievement of sustainable communities and environment. In order to be fossil-free, the chemical and material industry is in need of carbon-neutral building blocks from renewable resources for the diverse array of products that are currently produced from olefins and aromatics.
