“…Digestate produced from the anaerobic digestion process is assumed to replace conventional fertilizer. Every tonne of digestate produced in the biogas plant (wet weight) is assumed to replace 8.00 kg N, 5.00 kg NH 4 , 1.00 kg P and 1.50 kg K [17]. Composting is assumed to replace an avoided amount of produced inorganic fertilizer, and the amount is assumed to be equal to the digestate produced in the biogas plant.…”

This study will review the environmental implications of dynamic policy objectives and instruments outlined in the European Union 7th Framework Programme (EU-FP7) Project DYNAmic policy MIXes for absolute decoupling of EU resource use from economic growth (DYNAMIX) to address reductions in food consumption, food waste and a change in waste handling systems. The environmental implications of reductions in protein intake, food waste reductions, food waste management and donations are addressed using a life cycle approach to find the greenhouse gas (GHG) emissions, land use and water consumption. Data are provided from the Statistics Division of the Food and Agriculture Organization (FAOSTAT) food balance sheets for the European Union (EU) with a base year of 2010 and life cycle inventory (LCI) data from a meta-study of available GHG, land use and water consumption data for major food products. The implications are reviewed using a number of scenarios for the years 2030 and 2050 assuming policy instruments are fully effective. Results indicate that reductions in animal-based protein consumption significantly reduce environmental impacts, followed thereafter by reductions in food waste (assuming this also reduces food consumption). Despite the positive implications the policy mixes may have for targets for decoupling, they are not enough to meet GHG emissions targets for the EU outlined in the DYNAMIX project, although land and water use have no significant change compared to 2010 levels.

“…The possibilities to produce resourceefficient biofuels with good environmental performance differ between different biofuels and due to local prerequisites (Börjesson andMattiasson, 2008, Börjesson, 2009), and cases found in literature show that there is a potential to reduce GHG emissions substantially with a beneficial biofuel production system (e.g. Martin et al, 2014).…”

“…Most research within the industrial symbiosis field focuses on industry in general and not on the biofuel industry in particular. However, according to Martin et al (2014) focusing on IS within the biofuel industry there are many possibilities to improve environmental performance through exchanges of material and energy. Furthermore, Börjesson (2009) states that two of the most important components of an ethanol production system from a greenhouse gas (GHG) perspective is how by-products are used and what energy system is used, i.e., how the material and energy flows are organized in IS terms.…”

Conditions for resource-efficient production of biofuels for transport in Sweden

Transportation has continued to increase worldwide and fossil-fuel dependency is strong which leads to a number of problems, e.g. increased emissions of green-house gases (GHG) and risks related to energy security. Biofuels have until now been one of the few renewable alternatives which have been able to replace fossil fuels on a large scale. The biofuel share in relation to the total use of fuel in the transportation sector is still small, but in many places in the world political targets are set to increase the share of renewable fuels, of which biofuels are supposed to be an important part. Within the European Union targets for renewable energy have been set, including within the transportation sector, where 10% shall come from renewable sources by 2020 according to the EU Renewable Energy Directive (EU RES). Biofuels also need to fulfill the sustainability criteria in the EU RES, to be regarded as renewable. Depending on how biofuels are produced their resource efficiency varies, and the differences in environmental and economic performance can for instance be significant.The aim of this thesis is to describe and analyze conditions for a development towards increased and more resource-efficient production of biofuels in Sweden. The conditions have been studied from a regional resource perspective and from a biofuel producer perspective since it has been assumed that the producers are in possession of important knowledge, and potentially will play an important role in future biofuel development. The concept of resource efficiency used in this thesis includes an environmental and economic perspective as well as an overall societal dimension to some extent. The region of Östergötland in Sweden was used for the assessment of the resourcefocused biofuel potential for the year 2030, where two scenarios based on assessments regarding socio-technical development in relation to regional resources were used. The scenarios were based on semi-structured interviews with biofuel actors, literature studies and information from experts in the field. In the EXPAN (Expansion) scenario a continued development in line with the current one was assumed, but also an increased availability of feedstock primarily within the agricultural and waste sectors (also including byproducts from industry) for biofuel production. In the INNTEK (Innovation and Technology development) scenario greater technological progress was assumed to also enable the use of some unconventional feedstock besides increased available arable land and improved collection/availability of certain feedstock. Biomass feedstock from four categories was included in the potential: waste, agriculture, forestry and aquatic environments. One important feedstock which was not included in this study, but which is often included in studies of potential, is lignocellulosic material from the forest. This choice was also supported by the regional actors who judged it as less probable that there will be any large-scale use of such feedstock for biofuels in this region wit...

Abstract:In the last decades the increasing energy requirements along with the need to face the consequences of climate change have driven the search for renewable energy sources, in order to replace as much as possible the use of fossil fuels. In this context biomass has generated great interest as it can be converted into energy via several routes, including fermentation and anaerobic digestion. The former is the most common option to produce ethanol, which has been recognized as one of the leading candidates to substitute a large fraction of the liquid fuels produced from oil. As the economic competitiveness of bioethanol fermentation processes has to be enhanced in order to promote its wider implementation, the most recent trends are directed towards the use of fermentation by-products within anaerobic digestion. The integration of both fermentation and anaerobic digestion, in a biorefinery concept, would allow the production of ethanol along with that of biogas, which can be used to produce heat and electricity, thus improving the overall energy balance. This work aims at reviewing the main studies on the combination of both bioethanol and biogas production processes, in order to highlight the strength and weakness of the integrated treatment for industrial application.
