Frida Röyne: Life Cycle Assessment (LCA) of
bioproducts
Aim:
Evaluate how to use the Swedish wood as resource efficient as possible from an environmental perspective.
Expected results:
• Establish the environmental impact of new methods and tools used for refining of bioresources.
• Methodological development of actor based LCA.
Ongoing study:
• Investigate the environmental impact today caused by the cluster of chemical producing companies in Stenungsund with future scenarios where biobased material will replace fossil material .
Coming study:
• Environmental assessment of closing the loop of biobased plastics focused on the recycling process. • Comparison of the environmental impact of wood based products (chemicals, textiles, building
Johan Torén: Optimal localisation of second generation
biofuel production in Sweden.
Aim:
The goal of the project was to develop a model which will determine the optimal siting alternatives for the production of second generation biofuels from lignocellulose commodities in Sweden, given various
biofuel goals and different boundary conditions.
Results:
•A model which can be used for analysis of optimal siting of second generations biofuel production in Sweden.
•Consistent scenarios of biomass access and demand of renewable fuels in Sweden. The results is going to be published at f3´s homepage soon.
Participants:
Bio4Energy, SP, Innventia, Chalmers Tekniska Högskola, Linköpings Universitet, IIASA

´
s part of the project:
• Analysis of different estimated potentials for supply of forest biomass in Sweden. The analysis was conducted in the form of a literature review by Johan Torén.
• Development of consistent scenarios to be used in the coming phase of the project. Parameters included were supply of biomass, biofuel demand, population and transportation needs per capita. The scenarios were developed for the year of 2030 by Johan Torén and Johanna Mossberg

B4E Strategi
Ecophysiology Torgny Näsholm
Our research deals with nitrogen nutrition of plants in general and of forest plants in particular. Nitrogen, being the mineral element needed in largest amounts by plants is also, in most terrestrial ecosystems, limiting for plant growth. In Boreal forest ecosystems, this limitation is in spite of large stocks of organic nitrogen in the soil. Thus, the production of plant available nitrogen sources is a key process in these forests.
Using a broad array of techniques, we are trying to answer this question. With the help of dual (C-13, N-15) labelled amino acids we have quantified uptake of intact amino acids in various plants directly in the field. Many researchers in various ecosystems now use this technique. We have characterized the mechanisms enabling for plants to absorb amino acids. These findings enable for us to produce plants with drastically altered capacities for amino acid uptake, plants that can be used to study the importance of amino acids as nitrogen sources in various soils.
Our research deals also with carbon-nitrogen interactions in plants and the role of nitrogen for root:shoot allocation. It is well known that nitrogen availability is a strong determinant of root:shoot allocation of plants. But what roles do the different nitrogen compounds in the soil play for
allocation of carbon between above- and belowground compartments and in shaping plant structures? These questions are targeted in new projects within the ecophysiology competence area.
Because of the strong nitrogen limitation of forests in our part of the world, nitrogen fertilization usually results in substantial growth increases. The practice of adding nitrogen to forests has received increased attention recently, an interest driven by the strong demand for biomass from different sectors. Our research will provide the basic knowledge for understanding how trees react to increased nitrogen availability and help develop new fertilizers and new forests nitrogen
