1. Weed seed predation : a promising ecosystem service in agriculture
Sammanfattning : Enhancing biodiversity and promoting vital ecosystem services can reduce the global dependence on anthropogenic inputs in agriculture while securing crop yield. Weed infestation can severely reduce crop yield but the dominance of herbicides for weed control can impair human health, beneficial organisms and ecosystem service delivery. LÄS MER
2. Environmental, health, and safety assessment of chemical alternatives during early process design: The role of predictive modeling and streamlined techniques
Sammanfattning : Industrial chemicals are important for many aspects of modern life, though they can be harmful to the environment and human health. Environmental or safety concerns identified during the early design and selection of chemicals could motivate choices as to safer alternatives and process setups. LÄS MER
3. Adsorption Properties of MFI-Type Zeolite Films for Upgrading of Biofuels
Sammanfattning : With the depleting reservoirs of fossil fuels, increasing environmental concerns for flue-gas emissions from fossil-fuel combustion and growing world population, the need for the development of new sustainable fuels is higher than ever. However, to be able to compete with today’s mature technologies for production of fuels from fossil sources, new efficient processing alternatives for upgrading of biofuels must be developed. LÄS MER
4. Effects of Citric Acid on Starch-Based Barrier Coatings
Sammanfattning : With growing environmental concerns, efforts are made to replace petroleum based products with renewable alternatives. This is particularly evident in the packaging industry, where replacing synthetic polymers with renewable materials is of considerable interest. LÄS MER
5. Environmental Assessment of Emerging Technologies: The Case of Alternative Transport Fuels
Sammanfattning : There are several methods to evaluate the environmental performance of new technologies. The purpose of this thesis is to contribute to the methodological development of environmental assessments, with contributions from life-cycle assessment (LCA), theories on technical change and socio-technical scenarios.
