1. Frame Analysis in Environmental Conflicts : The case of ethanol production in Brazil
Sammanfattning : Governments and policy-makers are currently dealing with some key issues as energy security in countries dependent on oil imports; global economic development, including increased food production; and controlling global climate change and greenhouse gas emissions. The perception that biofuel could solve these challenges simultaneously has led to the implementation of policy and regulatory mechanisms on the mandatory use of biofuels, resulting in a sharp increase in biofuel production and consumption.

2. Lignocellulosic Ethanol Production: Studies on Sugarcane Bagasse, Paja Brava, Wheat Straw, Quinoa Stalks and Curupaú
Sammanfattning : Lignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. LÄS MER
3. Land and climate effects of bioenergy - Brazilian sugarcane ethanol and combined biofuel-district heating in Europe
Sammanfattning : According to the Intergovernmental Panel on Climate Change, use of fossil fuels is the largest source ofthe increase in atmospheric CO2. The second largest is land use change. To reach stringent climate targets,emissions from fossil fuel combustion and land use change will need to be reduced to near zerowithin a few decades. LÄS MER
4. Development of the Steam Pretreatment Process for Production of Ethanol from Lignocellulosic Biomass
Sammanfattning : At a time when natural petroleum resources are on the verge of depletion, and concern about climate change is increasing, the potential of lignocellulosic material for the production of bioethanol is well recognized. Ethanol can be produced from biomass through enzymatic hydrolysis and fermentation. LÄS MER
5. Improving the greenhouse gas balances of bioenergy systems: The cases of Brazilian ethanol production and combined biofuel/district heat production in Europe
Sammanfattning : According to the Fourth Assessment Report of Working Group I of the Intergovernmental Panel on Climate Change, the largest source of increased atmospheric CO2 concentration is fossil fuel use. The second largest is land-use change. LÄS MER
