non-foodcrops on marginallands as alternative solutionnot in competitionwithfood production Highly polluted, not suitable for food production & low productivity lands Energy crops: pros & cons
SETTING THE GOAL. 1 • Identification of suitable land and crops • capable of providing a suitable biomass substrate, without competing with food production • characterized by high yield, low cultural requirements and low environmental impact Evaluationtools
SETTING THE GOAL. 2 • development of an integrated evaluation method • capable of identifying bottlenecks and improvement options • suitable for decision making Evaluationtools
Extended LCA Approach: SUMMA (SUstainabilityMultidimensional and MultiscaleAssessment) Life Cycle Assessment “cradle to grave analysis” SUMMA Geographic Information System for spatial analysis the energy that is embodied in any form of energy, good or service Evaluationtools

BIOREFINERY IS “the sustainable processing of biomass into a spectrum of value-added products (chemicals, materials, food and feed) and energy (biofuels, power and heat).” Kamm, B.; Kamm, M. (2004). Principles of Biorefineries. Appl. Microbiol. Biotechnol. 64: 137-145 Biorefinery pattern
BIOFINE LINE Furfural Purification Furfural Reactor #2 LA Derivatives LA Extraction LA Conversion Reactor #1 Steam Formic Acid Hexose Feedstock Char Substance Pretreatment Make-up acid Energy Electricity • A high temperature, fast acid hydrolysis of biomass polysaccharides • The feedstock is hydrolysed with 1-5% mineral acid in two reactors • The first reactor hydrolyses the sugars and produces 5-hydroxymethyl furfural (HMF) from the C6 sugars and furfural from the C5 sugars • The HMF goes to the second reactor where levulinic acid is formed Biorefinery pattern

ENERGY ADVANTAGE • highersavingsof oil in the production ofchemicals and biomaterials (petro-chemicalsrequire more fossilenergy in the process) • ECONOMIC ADVANTAGE • higher market valueofbiochemicals (comparedto the market valueofthermalenergy) + highersavingsfromlargeramountof oil replaced the economicreturnresultstobehigher (the ratioofgrossincometocostsisabout 2:1) Biorefinery pattern
SUMMA PERFORMANCE INDICATORS Biorefinery pattern
Conclusions. 1 • The energy and environmental performance of the B. carinatabioenergy approach is not feasible at the level of Campania regional agriculture. • If agricultural residues are exploited for the extraction of chemical building blocks, both the energy and the economic balances are improved, due to the high added value of biochemicals. • By converting waste and residues (also from food manufacturing industry and urban systems) into value added chemicals, combustion and landfilling are avoided and additional energy, economic and environmental benefits are gained Conclusions
Conclusions. 2 • The evaluation tools applied are able to capture several different aspects (methodological, spatial and time-scale) and integrate them into a whole picture. • By means of SUMMA approach, the most sustainable option (or set of options) can be identified and choices among alternatives are undoubtedly facilitated. • Additional insights on constraints and scenarios can be gained if SUMMA database and indicators are further processed via MuSIASEM (Multi-ScaleIntegratedAnalysisofSocietal and EcosystemMetobolism) and ASA (Advanced Sustainability Analysis) Conclusions
