1. Process development for platform chemical production from agricultural and forestry residues
Abstract : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pretreatment impair the economic feasibility of such biorefineries. READ MORE

2. Climate impacts due to albedo change in LCA of agricultural systems
Abstract : Agricultural systems for production of food, energy and materials are a major driver of climate change, due to land use and greenhouse gas (GHG) emissions along the supply chain. Crop cultivation also affects the climate by changing land surface albedo, i.e. the fraction of solar radiation reflected back from the ground. READ MORE

3. Greenhouse gas emissions from Swedish milk production : towards climate-smart milk production
Abstract : Greenhouse gas (GHG) emissions from food production represent 19-29% of global anthropogenic GHG and the dairy sector alone is estimated to contribute around 3%. This thesis assessed GHG estimates for milk production (i.e. milk carbon footprint (CF)) in a life cycle perspective. READ MORE

4. Industrial hemp (Cannabis sativa L.) – a high-yielding energy crop
Abstract : Bioenergy is currently the fastest growing source of renewable energy. Tighter sustainability criteria for the production of vehicle biofuels and an increasing interest in combined heat and power (CHP) production from biomass have led to a demand for high-yielding energy crops with good conversion efficiencies.

5. Climate-friendly rice - characterisation of rice varieties associated with low-methane emissions and improved bioenergy properties
Abstract : Paddy rice cultivation contributes to global warming by emitting methane into the atmosphere. The aims of the work presented in this thesis were to breed climatefriendly rice varieties, to increase rice straw utilisation to reduce the impact of rice cultivation on the environment. READ MORE
