Guillermo San Miguel Abstract This publication demonstrates the practical application of Social Life Cycle Assessment (S-LCA) methodology in the analysis of a 50 MWe Concentrating Solar Power (CSP) plant located in Spain The assessment makes use of two complementary analytical approaches: (1) a generic social hotspot analysis based on the social risks related to financial flows generated by the provision of goods and services taking place during the life cycle of the power generation system, and then (2) a site-specific analysis focussing on the social performance of the construction/energy company involved in the construction and operation of the power plant The site-specific analysis followed the procedures proposed by UNEP/ SETAC but included a new classification/characterization model suited to the particularities of the project and the energy sector The analysis considered four stakeholder categories (workers; local community; society; and value chain actors) and used the number of worker hours as activity variable for the quantification of social risks Worker hours attributable to each of the stages of the life cycle of the CSP system were calculated using input-output (IO) analysis The impact assessment phase of the S-LCA was carried out using a Social Performance Indicator (SPI), which required the estimation of performance reference points for a series of indicators/subcategories proposed by the UNEP/SETAC Guidelines The SPI calculated for the CSP plant (+0.388 for a ±2 range) suggested that the use of solar power results in an increase of social welfare in Spain, primarily with regards to socioeconomic sustainability and fairness of relationships The inventory data used in the social hotspot analysis were monetary flows attributable to each of the processes considered in the life cycle of the power system These flows were assigned to the corresponding sector of the producer country The Social Hotspot B Corona (&) Copernicus

results showed that the life cycle phase contributing the most to the social risk of the solar power system was operation and management This is due primarily (over 75% of the weighed risk) to the social risks associated with the supply chain of the natural gas used as auxiliary fuel For Spain, the main social risks associated with the solar power plant were related to gender inequality and corruption, and to a lesser extent to injuries and immigrants Some of these risks were confirmed in the site-specific assessment The paper ends with a discussion about the application of Multi-Criteria Decision Making (MCDM) for evaluating the results obtained in this Social-LCA in combination with environmental and economic oriented LCA Keywords S-LCA Stakeholders Á Electricity Á Social performance Á Spain Á Social risks Introduction The UN World Commission on Environment and Development (WCED), also known as the Brundtland Commission, developed between 1983 and 1987 the grounds for the modern interpretation of sustainability In its final report “Our Common Future”, the Brundtland Commission produced a definition of Sustainable Development that is still widely accepted today: “the development that meets the needs of the present without compromising the ability of future generations to meet their own needs” (WCED 1987) That report also stated that the concept of sustainability rests on three elements: economic growth, environmental protection and social equality At present, the Sustainable Development Goals (issued by the United Nations in 2015, and a continuation of the Millennium Development Goals) (Biermann et al 2017) are in the front line of international, national and local agendas Public administrations and customers are exerting pressure on companies to ensure that the principles of sustainable development are incorporated into the goods and services that they supply to the market The practical application of this ambition necessarily entails the use of a systematic methodology capable of quantifying the sustainability of specific goods and services in an objective manner A holistic methodology referred to as life cycle sustainability assessment (LCSA) is currently under development with the purpose of integrating the three pillars of sustainability under a coherent life cycle approach UNEP/SETAC Life Cycle Initiative states in its report “Towards a Life Cycle Sustainability Assessment” that LCSA may be seen as the summation of three analysis tools: Environmental Life Cycle Analysis (E-LCA), Life Cycle Costing (LCC) and Social Life Cycle Analysis (S-LCA) (UNEP/SETAC 2011) This concept is illustrated in equation SLCA = E-LCA + LCC + S-LCA Social Performance of Electricity Generation in a Solar … A more advanced and flexible approach to LCSA was developed under the Coordination Action for innovation in Life Cycle Analysis for Sustainability (CALCAS) (2006–2009) project (Heijungs et al 2009) This new conceptual framework relies on expansion of the scope of conventional E-LCA to incorporate the economic and the societal dimensions of the system under consideration The CALCAS project approach provides the practitioners with more flexibility in the selection of the analytical tools employed to evaluate different aspects of the system and provides an integrated framework where the results may be evaluated as a whole (Guinée et al 2011) The ultimate purpose of S-LCA is to assess the effect of a given product on human wellbeing As the name suggests, the analysis applies a life cycle approach that takes into consideration social and socio-economic effects associated with the extraction and processing of raw materials required for the fabrication of the product, manufacturing activities, transportation and distribution, utilization and any end-of-life actions that may be associated with the product (reuse, recycling and final disposal) These effects considered in S-LCA are primarily those generated by the companies participating in the different stages of the life cycle of the product under consideration.1 This performance has an effect (positive or negative) on the wellbeing of a series of stakeholders, which typically include Consumers, Workers, Local Community, Value Chain Actors and Society S-LCA may be used on its own or, as described above, it may be part of a broader Life Cycle Sustainability Assessment (LCSA) (Guinée et al 2011; UNEP/ SETAC 2011) The scientific community recognizes E-LCA and LCC as mature methodologies, while S-LCA is usually regarded as being at an early stage of development in terms of methodological harmonization and acceptance (Cinelli et al 2013) 1.1 Key Methodological Issues in S-LCA Since its inception in 2002, the UNEP-SETAC Life Cycle Initiative has distinguished itself as a key promoter and developer of S-LCA methodology The Guidelines for Social Life Cycle Assessment of Products (from now on the S-LCA Guidelines) have become a landmark and a key reference in the field (UNEP/ SETAC 2009) This methodology operates on the principles of ISO 14040 and 14044, with the typical four interrelated phases: (i) identification of goal and scope, (ii) inventory analysis, (iii) impact assessment and (iv) interpretation The practical application of these guidelines is facilitated with the Methodological Sheets for Sub-Categories in Social Life Cycle Assessment (S-LCA) (UNEP/SETAC 2013) In the identification of goal and scope phase, the S-LCA practitioner needs to set up the basis of the investigation including identifying the objectives of the In addition, the ultimate utility of the product may also be considered in the analysis 96 M Ferrante et al Journal of Fashion Technology & Textile

included three classifications: (i) Bioenergy creation, (ii) Environmental issues, (iii) Environmental target This implies LCA techniques have been broadly utilized as a part of evaluating the natural effect from different sorts of bioenergy generation process Uniquely, the greenhouse gases pulled in more consideration in this exploration territory Because of the natural impacts, confinements, and additionally changes of the non-renewable energy sources, usage of substitution energies, for example, sustainable power sources is one of the principle arrangements keeping in mind the end goal to defeat to the vitality concerns Among sustainable power sources, bioenergy and its related advancements is imperative for specialists and approach producers Albeit diverse bioenergy advances have been

reasonable connection between’s vitality utilization and expectations for everyday comforts of individuals Three classes of vitality assets are accessible which are petroleum products, sustainable sources, and atomic sources From the earliest starting point time of the mechanical unrest, the oil, coal, and petroleum gas called petroleum derivatives have been utilized to meet the real vitality necessity of the entire globe The first and the most vital vitality wellspring of people was biomass Today, because of improvements in the innovative biomass idea, the points and fields of utilization of biomass have been incredibly extended and progressed (Taylan et al 2018) Each sustainable power source is performing in an unexpected way; one could be best alternative for one area/reason/season and could not perform with that productivity at another area/reason/season (Jayakumar 2009) Among the sustainable power sources, biofuels are the most well-known sustainable power source due to the accessibility of crude material (biomass), all over and round the year and furthermore because of its appropriateness in transport vehicles and ventures (Nigam and Singh 2011) Biomass can be utilized to deliver sustainable power, thermal vitality, or transportation energizes (biofuels) Biomass is characterized as living or as of late dead organism and any results of those creatures such as plant or animals The term is largely comprehended to reject coal, oil, and other fossilized leftovers of life forms, and additionally soils In this firm wisdom, biomass incorporates every single living thing About biomass vitality, notwithstanding, the term alludes to those harvests, deposits, and other organic materials that can be utilized as a substitute for petroleum derivatives in the generation of vitality and different items Living biomass takes in carbon as it develops and discharges this carbon when utilized for vitality, bringing about a carbon-impartial cycle that does not expand the climatic centralization of ozone harming substances There are conventional and present days, henceforth two sorts of bioenergy sources Customary biomass sources incorporate fuelwood; dried creature squanders, and customarily delivered charcoal Current biomass sources involve fluid biofuels created from farming deposits and woods squanders The bioenergy advances can be considered mechanical cogeneration and biorefineries, pellet warming frameworks, biofuels (bioethanol, biodiesel, and bio-hydrogen), bioplastics, biogas created by anaerobic absorption of buildups, and some other related advances (Eskandary 2017; Demirbas et al 2016) Social Life Cycle Assessment of Renewable Bio-Energy … 101 Bioenergy In spite of the fact that the energy request has expanded quickly, yet the impediments, natural, and value changes of petroleum derivatives has caused the strategy producers not look them as a protected wellspring of vitality supply for the social orders Along these lines, examinations on substitution arrangements, for example, usage of elective vitality sources with low emanation and ecological impacts have been unavoidable In ongoing decades, use of sustainable power sources keeping in mind the end goal to make a functioning job on vitality supply arrangement of the nations have been stressed (Aslani et al 2012; Karkoodi et al 2018) Bioenergy is one of the numerous various assets accessible to help take care of our demand for vitality It is named a type of sustainable power source got from biomass—natural material—that can be utilized to deliver warm, power, transportation energizes, and items (Aslani et al 2018) The vitality put away in biomass can be discharged to create inexhaustible power or warmth Biopower can be produced through burning or gasification of dry biomass or biogas caught through controlled anaerobic absorption Cofiring of biomass and petroleum products is a minimal effort method for decreasing ozone depleting substance emanations, enhancing cost-adequacy, and diminishing air toxins in existing force plants Thermal vitality is frequently created at the size of the individual working, through direct ignition of wood pellets, wood chips, and different wellsprings of dry biomass Bioenergy offers agriculturists and option in contrast to oil based vitality sources, and new market openings for homestead items At the point when biomass feedstocks are scorched, aged or responded through a vitality transformation process, they restore some carbon dioxide and water and discharge the sun’s vitality Since plants have the capacity to store and afterward discharge vitality along these lines, they go about as a characteristic battery This prologue to bioenergy offers a brief and non-specialized diagram of bioenergy feedstock generation The Significance of Biomass, Biofuels, and Bioenergy Natural materials are the fundamental wellspring of biomass, which are put away under the daylight in request to shape concoction vitality Then again, sugar stick, wood and wood squander, straw, creature excrement, and numerous other horticultural squanders are additionally biomass hotspots for bioenergy generation For example, the green plants convert daylight into plant material through photosynthesis There are three reasons that make biomass an appealing feedstock; first, biomass and its innovation are inexhaustible assets and might be reasonably enhanced later on Second, as a positive ecological property of biomass, it results in less arrival of CO2 and lower sulfur substance (Demirbas et al 2016) 102 A Saravanan and P S Kumar The biomass forms are the wellspring of direct burning for the squanders evaluation and power age in the industrialized nations, for example, bioethanol and biodiesel can be gotten as fluid energizes Thus, warmth and power can be created from products and rural squanders used later on Figure shows that renewable bioenergy products The lignocellulosic bioenergy harvests, for example, bush willow, which are required to have a noteworthy job in atmosphere alleviation systems They examined two yield preliminary datasets containing genotypes from progressive rounds of reproducing utilizing a progression of blended models Their examination showed an incremental change in yield with progressive rounds of reproducing through the advancement of interspecific triploid half-and-halves Then again, the age of power from biomass later on relies upon biomass-coordinated gasification and gas turbine advances (Alidrisi and Demirbas 2016) It is expected that biomass will be able to compete propitiously with fossil fuels in the chemical feedstock industry The flexibility and availability of biomass make it an important renewable energy resource A productive plantation option and operation is important for a sustainable biofuel production potential The plantation of suitable crops may be used as biomass source for bioenergy production, which can decrease the environmental contaminations in red sea region due to sewage pollution It is normal that biomass will have the capacity to contend auspiciously with non-renewable energy sources in the concoction feedstock industry The adaptability and accessibility of biomass make it an essential sustainable power source asset A profitable estate alternative and activity is vital for an economical biofuel creation potential The manor of reasonable harvests might be utilized as Fig Renewable bioenergy products Social Life Cycle Assessment of Renewable Bio-Energy … 103 biomass hotspot for bioenergy creation, which can diminish the natural defilements in red ocean district because of sewage contamination The principle innovation utilized for biomass transformation is the bio-refineries that coordinate the hardware to deliver fills from biomass; produce power, warmth, and a few synthetic compounds; and can increase the value of the monetary changes Bio-refineries can deliver in excess of one item by utilizing a few biomass components also, their intermediates; in this way amplify the monetary estimation of biomasses got from crude materials (Nizami et al 2017) • Biogas from biomass with organic change In parallel to the quick industrialization and populace development, an extensive increment in the vitality and modern crude material necessities have been seen in creating nations Contingent upon this development: the transfers of natural deposits and results delivered in the administration and assembling enterprises are the real issues for the city specialists, which additionally have genuine natural effects The regular composts from the plant yields balance the pH, N, P, K of the dirt with normal ways and move up to the perfect level The dirt harvest yields expanded in an economical way over the time can diminish the requirement for compound composts necessity Thus, the impacts and harms of synthetic manures on nature will be limited by diminishing the utilization of them (Nasir et al 2014; Werle and Dudziak 2014) Life Cycle Examination of Biogas Plant The existence cycle investigation of a full-scale biogas plant was led in the examination In the existence cycle examination, the natural impacts of the biogas procedure, result generation from the biogas, what’s more, the cogeneration unit where the power is created are additionally assessed in light of the ISO 14040 (ISO, Environmental administration Life cycle appraisal standards and structure (ISO 14040), 2006 Brussels: European Committee for Standardization) principles The existence cycle examination comprises of four stages in this investigation: the objective and degree definition, the examination of stock, the effect appraisal, and translation of results The objective also, scope definition plans to distinguish the principle objective of starting this investigation It is to make and assess the existence cycle investigation of a mechanical scale biogas plant that produces biogas from steers compost, poultry excrement, and fermentation of cheddar whey At that point, the outcomes gotten will be assessed and conceivable damages or advantages of biogas creation on the earth by fermentation have been evaluated (Dey and Bhattacharya 2016) Figure shows that Life cycle stages of bioenergy products 104 A Saravanan and P S Kumar Fig Life cycle stages • The motivation behind a proof of idea LCA is: – Have certainty that advances deliver sustainable power source with a positive natural effect profile, essentially in connection to typified fossil vitality and GHG balance – Acquire understanding into ecological favourable circumstances and dangers related with advances – Provide bits of knowledge into ecological difficulties of distinctive feedstocks and advances – Create a level playing field correlation against current petroleum product vitality sources – Provide ‘problem area’ investigation of ecological effect also, advantages to direct advancements • Necessities and guidance for undertaking a LCA of bioenergy Determining the objective of the investigation is a central prerequisite of a LCA The objective of the investigation plots the motivation behind the examination and, in doing as such, recognizes the crowd for the investigation and a structure of key inquiries to be replied by the investigation The ‘useful unit’ gives a typical premise for examination of results in any LCA think about while the framework limit portrays the procedures to be incorporated and rejected in the LCA These two components are firmly connected in light of the fact that the definition of the useful unit will, to some extent, choose where the limit is drawn With bioenergy, frameworks there are two potential approaches to characterize the unit of examination: Another thought for the framework limit is the utilization of an edge for including distinctive procedures, which is alluded to in LCA measures as the cutoff Social Life Cycle Assessment of Renewable Bio-Energy … 105 criteria This is utilized to disentangle information gathering and demonstrating in the LCA, enabling immaterial streams to be rejected There might be particular task composes where capital gear and foundation is huge and ought to be incorporated Nevertheless, to keep the LCA viable and streamlined capital hardware and framework might be rejected from generally LCAs The framework limit contemplations to with co-items and waste are portrayed The creation of proportionate amounts of fuel with certain vitality content or the creation of proportionate amounts of administration is given by the fuel or vitality Figure shows that Facilitating biomass flow along the bio-energy chain Bioenergy utilizes sustainable biomass feedstocks from numerous sources Inexhaustible biomass feedstocks utilize the procedure of photosynthesis in plants to catch the sun’s vitality by changing over carbon dioxide (CO2) from the air and water (H2O) into sugars and complex oil and fiber mixes made up of carbon, hydrogen and oxygen These vitality rich sugars, oils furthermore, filaments can be gathered and utilized for some kinds of bioenergy There are many ways to transform natural materials into vitality, despite the fact that right now just a couple of them speak to authentic here and now open doors for the normal ranch or rustic landowner Bioenergy can be created from feedstocks for example, trees, rural products, plant buildups, creature parts and numerous other natural materials The advantages of one feedstock versus another are territorially particular This makes feedstock determination a key thought in bioenergy creation Feedstocks might be committed to vitality generation or then again non-devoted Feedstocks that are committed are regularly called vitality crops Every feedstock has focal points and detriments that may incorporate how much usable biomass they deliver; soil composes required, water and vitality inputs, vitality thickness, air quality advantages, creation cost and different contemplations Figure shows the renewable bioenergy products Fig Facilitating biomass flow along the bio-energy chain 106 A Saravanan and P S Kumar Fig Renewable bioenergy products Feedstocks require a transformation process keeping in mind the end goal to take crude materials and turn them into valuable bioenergy, for example, power, biodiesel, ethanol, biobutanol, methane, warm what’s more, other bioenergy items Remember that collecting, drying to the right dampness content, transporting to the essential area and providing an adequate amount of biomass are essential contemplations that are just quickly said in this prologue to bioenergy Each kind of feedstock may require a marginally extraordinary change process, yet numerous feedstocks can be changed over utilizing comparative procedures and advancements • Thermochemical Conversion Warming biomass helps a concoction response (a thermochemical process) and makes valuable bioenergy items, for example, gases, fluids and warmth Power created from biomass is alluded to as biopower, and the mix of both warmth and control is regularly alluded to as cogeneration or consolidated warmth and power (CHP) The general productivity of these coordinated frameworks is altogether higher than both of the frameworks alone Social Life Cycle Assessment of Renewable Bio-Energy … 107 • Warm Process Heat and Space Heat Consuming biomass specifically can be utilized to deliver both process warmth and space warm Process warm is crucial to many assembling forms and is utilized in an assortment of farming applications counting grain and yield drying Space warming is the most widely recognized utilize Both substantial boilers in assembling offices and little stoves in shops are every now and again utilized for space warm Wood, wood chips and feed can be utilized for both process warmth and space warm, and are promptly accessible on the ranch • Ignition in a Direct-terminated or Customary Steam Boiler The consuming of feedstocks for vitality has been drilled for a long time One of the most seasoned business strategies for creating power is through the consuming of wood or charcoal to create steam The steam is channelled into a turbine that twists a generator used to make power, or then again biopower An issue with consuming feedstocks in a steam heater is that an awesome arrangement of vitality is lost in the transformation procedure Pre-handling biomass by pelletizing, torrefaction (superheating in a low-oxygen condition) or on the other hand making dense biomass briquettes has enhanced the productivity of consuming woody biomass These procedures are costly what’s more, not constantly sparing given current fossil fuel costs • Pyrolysis Pyrolysis is gotten from the Greek words pyro, which means fire, and lysys, which means disintegration Pyrolysis is a technique for delivering syngas furthermore, biocrude, otherwise called bio-oil or pyrolysis oil Pyrolysis utilizes warm disintegration by warming biomass at temperatures generally more noteworthy than 400 °F (204 °C) Biocrude is shaped when syngas delivered amid pyrolysis is re-consolidated into fluid biocrude There are couple of chances to utilize grungy biocrude specifically on the ranch and a constrained market Biocrude can be refined into excellent hydrocarbon fills, for example, diesel, and gas and fly fuel These fluid fills can be utilized in inside burning motors as a synthetically indistinguishable substitute to oil energizes • Biochemical Conversion Microorganisms, yeasts and other living chemicals age material, for example, sugars and proteins and convert them into valuable alcohols or other fluid fills These procedures are known as biochemical change forms Corn ethanol and other grain alcohols are the absolute most normal powers delivered along these lines Different strategies incorporate catching methane created when microscopic organisms separate compost from domesticated animals and poultry generation, human sewage and landfill waste to consume it for warmth and biopower 108 A Saravanan and P S Kumar (i) Anaerobic Digestion Anaerobic digesters separate (or process) natural issue without oxygen (anaerobic) to create methane and different gases and coproducts that are helpful on the homestead This gas blend is regularly alluded to as biogas or digester gas Biogas is a burnable and regularly comprises of 50 to 60% methane Biogas can be scorched in a motor to produce biopower and warm vitality or prepared further into other fuel composes for example, methanol Refined biogas can be utilized as compacted gaseous petrol (CNG) and melted petroleum gas (LNG) in vehicles, among other employments Figure shows the diverse bioenergy technologies i.e., the diverse innovations to deliver vitality from biomass The characterization under the general name of Chemical/Biochemical innovations handling advancements which are principally started by the contact of the crude material with concoction items (i.e hydrolize, transesterification) as well as biomolecules or microorganisms (anaerobic assimilation, aging) In thermochemical handling advances, warm is the most vital parameter to be viewed as (notwithstanding when concoction responses are likewise present) Ignition advancements include handling innovations in which the crude material is oxidized with a vital warmth improvement • Innovation Evaluation Because of the absence of assets and high costs of innovative work process, contributing on advancements is viewed as a test Assessing advances is recommended as an apparatus for helping speculators and arrangement creators in basic leadership process Innovation assessment is a kind of social examination, which explores on impacts of another innovation on society At the end of the day, it is a precise examination device, which assesses significance and circumstance of an innovation In addition, if the innovation investigation is led periodical, intentional Fig Diverse bioenergy technologies Social Life Cycle Assessment of Renewable Bio-Energy … 109 and on time, it could uncover unpredicted auxiliary natural, social and social impacts (Tran 2007) There are diverse innovation assessment techniques, for example, economic analysis, system, designing, impact analysis, scenario analysis, road mapping, risk analysis, and so on Ecological Effect Classifications The ecological effect classifications speak to the contrasted classes or kinds of ecological effects that are incorporated into the examination They incorporate quantitative characterisation models that connection the stock streams, for instance ‘carbon dioxide emanation to air’ or ‘nitrate emanations to freshwater’, to equivalent ecological impacts with pointers, for this situation an Earth-wide temperature boost potential (GWP) and eutrophication separately While a wide range of aspects of ecological science utilize ecological pointers, in LCA they are especially testing since they evaluate rudimentary streams and coming about ecological effects from over the entire, frequently all-inclusive circulated supply chain, and for an expanded time—commonly 100 a long time or more It is critical to survey and assess the LCA results being aware of these difficulties Note: the ecological effects of bioenergy/biofuel can be more extensive than can be essentially incorporated into a LCA • Prerequisites – – – – – – – – Impact classifications for use in the LCA are: Environmental change Petroleum derivatives asset exhaustion Petroleum derivative vitality utilize (net calorific esteem) Particulate issue development Eutrophication Destructive water utilize Arrive utilize Multi-usefulness and Allotment Multi-usefulness or co-generation alludes to a process that makes more than once helpful item yield For instance, sugar stick processing produces sugar juice (which is refined to sugar) and bagasse (which is for the most part utilized for cogeneration of steam and power) The sugar refining produces crude sugar and molasses It is an intrinsic piece of the bio-economy where numerous items depend on co-items or potentially deliver other valuable co-items Feedstocks, which have regularly been 110 A Saravanan and P S Kumar thought of as waste, are in LCA terms considered as co-items where the feedstock has set up utilizes or potentially advertises Prerequisites and suggestion The assignment of effects between individual items in multifunction forms will pursue the accompanying pecking order: – Subdivision of procedures; – Designation in light of causal connections of data sources and outflow to yield items; – Framework development for joint generation, and – Assignment in light of vitality content or financial esteem The impacts of elective ways to deal with multifunctionality ought to be shown in the commercialisation LCA For waste utilized as a feedstock, the effects related with its dealing with and handling will be incorporated into the LCA Moreover, the elective destiny of that material (landfill, left on field) ought to be incorporated into the computation For instance, for rice bodies that are right now discarded to landfill, a bioenergy procedure that gathers them for use in vitality generation would incorporate the evaded landfill impacts (e.g maintained a strategic distance from methane emanations and dodged carbon stockpiling) in the framework limit References Alidrisi, H., & Demirbas, A (2016) Enhanced
