“…The LU and CWU contributions from the Ukraine were raised significantly as a result (Table S2, Electronic Supplementary Material). Felten et al (2013) While this LCA study serves to highlight geographically disproportionate emissions and demands on resources, it is limited in detail to gauge the consequence of these impacts. The significance of emissions may be on a highly localised level, e.g.…”

Purpose The European Union relies on seafood imports to supply growing demand that European production has failed to meet. Politically motivated media reports have denigrated competing imports in favour of local production. While life cycle assessment (LCA) measures global impact of value chains, it often fails to contextualise them. Using LCA, this article takes farmed Scottish Atlantic salmon as a case study of Blocal^production to identify and map the contributions to global environmental impact. Methods Data on the Scottish salmon value chain were collected by structured survey from a large international feed mill, six farms and a major processor. Secondary data were collected from available literature on feed ingredients and background data from EcoInvent2.2. A mid-point CML2001 approach was adopted focussing on global warming potential (GWP), acidification potential (AP), eutrophication potential, ozone depletion potential, photo-chemical oxidation potential, consumptive water use and land use. Results were displayed as contribution analyses of materials and processes and mapped geographically using area plots. Results and discussion Far from being a Blocally^produced commodity, nearly 50% of the feed ingredients were sourced from South America and less than 25% originated in the UK.It was found that over 90% of the impact to farm-gate was embodied in feed, apart from eutrophication potential which was high at the farm from direct nitrogenous emissions into the marine environment. The majority of impacts do not occur in Scotland, particularly for land and water use, which occur at a more geographically significant level than GWP or AP, which are more global or regional impacts, respectively. High GWP emissions from vegetable-based ingredients were related to soil management and energy intensive processes such as wet milling to produce gluten from wheat and maize, sunflower and rapeseed oil processing. Conclusions The results show that in an age of globalised commodity trading, concerns around Blocal^production are often misleading. As consumers try to make more responsible purchase choices, they may be misled over the global impacts their choices are having. There are clearly trade-offs between different feed ingredients, especially regarding substitution of marine ingredients with those of vegetable origin. While marine ingredients perform comparatively well, they are highly limited, and biodiversity impacts of different ingredients are less clear and difficult to compare.

Abstract-The idea of this study was to descript the output and feasibility of sand utilization from mount Sinabung eruption activities. The sand used as materials to produce planting media for vegetables. The experiment started from collecting the sand with pretreatment then added by certain material such as: waste of coffee skin after fermented as compost with goats manure, the urine of red sugar and liquid phase red sugar and then prepared to make shape by pressure tool. Hydraulic pressure tool applied to construct the matrix media with cylindrical shape variation. In this application, the shape type of matrix media was used to grow different plants such as: onion crop, local red chili,and vanilla plants. The most important result is the possibility to increase the value of sand from Sinabung eruption that can be used as planting media. The media also can be used in the certain place around the living place to increase the income of the people Sinabung victims. This idea is possible to increase the productivity of the people around the mount Sinabung.

“…This indicates that the number of countries with specific objectives in RES has doubled in the last 6 years (REN 21, 2012). The countries that support RES growth also aim at utilizing the benefits of these renewable and less contaminating resources, in pursuit of achieving national and international environmental aims, mainly regarding the reduction of Greenhouse Gas emissions (GHG) and other local pollutants (Akbulut, 2012;Li et al, 2013;Zhang et al, 2013;Felten et al, 2013;Sardianou and Genoudi, 2013).…”

Argentina plans to reach from 3% to 10% biomass participation for the internal supply of primary energy for 2015. However, biomass exploitation requires detailed studies at a local level for territorial energy planning, to achieve the expected energy and environmental benefits. This study, performed in the north of Argentina (Lerma Valley, province of Salta) is a step in this direction. The objective was to identify, characterize and quantify biomass feedstock availability in the region and its energy supply, studying the demand and utilization alternatives; and building different methodologies of quantification. The feedstock examined includes agricultural waste (AWB), municipal solid waste (MSW), and woody biomass (three main ecosystems and four species of Acacias spp.). They are annually producing 17,800 t.yr -1 (equivalent to 206,000 GJ.yr -1 ) of AWB; 24,100 t.yr -1 (around 34,000 GJ.yr -1 as biogas) of MSW (wet weight) and 213,000 t.yr -1 (or 3.1 million of GJ.yr -1 ) of woody biomass. The Acacias constitute 74% of the Shrubland's potential bioenergy (213,000 GJ.yr -1 ). This report will make possible the application of realistic energy projects for the area, promoting efficient exploitation of resources and generating positive local impact. The main bottlenecks for the implementation of such projects and some possible strategic solutions are identified. The proposed methodologies might be used to other geographical regions, within programs of territorial energy planning. In addition, the new data set of available worldwide biomass resources and the scientific knowledge in the field of bioenergy that has been generated, both constitute fundamental contributions for bioenergy promotion.
