IntroductionTheobjectiveofWorkPackage6(WP6)istoperformanenvironmental,economicandsocialsustainabilityassessmentsofcasestudiesdrawnfromthefourtechnicalWorkPackages(WP2toWP5)ofAgroCyclebycarryingoutaLifeCycleAssessment(LCA),LifeCycleCosting(LCC)andsocialLifeCycleAssessment(S-LCA).Deliverable6.1createdtheintegratedsustainabilityassessmentframeworkguidelinesfortheLCA,LCCandS-LCAanalysis.ThishasnowbeenpublishedontheAgroCyclewebsite(www.agrocyle.eu)andservesastherulesforhowtheanalysiswillbecarriedoutforeachofthefourcasestudiesdefinedinthisdeliverablereport.Deliverable 6.2 presented a biomass supply chain evaluation, with a fullcharacterisation of the available agricultural waste, co-products and by-products(AWCB) and their current treatment methods or uses, and related systems. Theoutcomeofthisdeliverableprovidesthereferencescenario(business-as-usual(BaU))withwhichthefourAgroCyclevalorisationsystemsarecomparedtodeterminethechangeinimpactandanypotentialbenefits.Deliverable6.3and6.4areinterimreportsondataavailabilityfortheenvironmentalLCA and LCC, respectively. To evaluate the overall sustainability performance ofAgroCycle technologies, the social impacts also need to be investigated. Thisdeliverable, D6.5, is an interim report on the methodological framework, datainventoryandprogressofsocialLCAforfourAgroCycledemonstrationcasestudies.From Work Package 2 the case study is micro anaerobic digestion of animalmanure/slurry; from Work Package 3 the case study is the valorisation of riceproduction by-products (predominantly bran) to produce fertiliser; from WorkPackage4thecasestudyisthevalorisationoffruitprocessingwastewatertoproducesingle cell protein; and fromWork Package 5 the case study is the valorisation ofpotatoprocessingby-productpulp(fibre)toproduceabioplastic.As the AgroCycle technologies are at early technology readiness (TRL 1-3), thetechnologieswill not be adopted at sectoral or factory level during the AgroCycleproject.Therefore,someofsocial-economicperformanceoftheAgroCyclecasestudysupply chainsarenotavailable through surveyorvalidatednational statistics. ThisrestrictedthefeasibilityofdevelopingaprocessbasedsocialLCA.Todealwiththistechnical issue,an integratedhybridLCAmodellingapproachwasused.ThehybridLCA combined economic input-output analysiswith a process-based LCAmodel.
