2. Environmental Assessment and Strategic Technology Choice : The Case of Renewable Transport Fuels
Sammanfattning : The scale of the required changes is huge, and time is limited if we are to avoid the most severe effects of climate change. To reduce greenhouse gas emissions from road transport, several fuels and electricity originating from renewable energy sources have been proposed, all of them in different stages of development and with various and shifting environmental impacts.

3. Energy and Environmental Factors in Food and Beverage Production Systems : An Analysis of Tomatoes, Whisky, and Beer
Sammanfattning : Given the anticipated global population of approximately 10 billion by 2050, the task of ensuring adequate sustenance for all within the constraints of Earth's limited resources presents a significant challenge. The production of food and beverages demands considerable energy investment, as well as other essential resources such as water and nutrients. LÄS MER
4. Anaerobic digestion of horse manure : renewable energy and plant nutrients in a systems perspective
Sammanfattning : In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. LÄS MER
5. From waste problem to renewable energy resource : exploring horse manure as feedstock for anaerobic digestion
Sammanfattning : A sustainable energy system requires, according to energy policies, reduced emissions of greenhouse gases, increased ratio of renewable sources of energy and more efficient use of energy. Horse manure could be regarded as waste, but also as a resource for renewable energy and plant nutrients. LÄS MER
