Yazdeen, Haji Haji. "Integrating Material Flow Cost Accounting with Life cycle assessment to Assess the Economic an Environmental Performances of Selected Wood Industries in the Landes de Gascogne Forest, France." Electronic Thesis or Diss., Bordeaux, 2023. http://www.theses.fr/2023BORD0153.
Full textThere is an increasing understanding that our consumption and production patterns have to change to stay within our planetary boundaries, the planet being unable to indefinitely assimilate the effects of current anthropic activities. Correspondingly, in recent years, growing concerns about climate change pollution and biodiversity loss have driven business organizations to change their priorities, not only to achieve economic objectives, but also to consider ecological goals. Forestry, an important part of natural systems, has been a traditional supplier of renewable raw materials for industrial use (e.g., sawmilling for construction wood, pulp and paper, particle boards), as well as for domestic fuelwood. Although many studies have been conducted in this field, little attention has been paid to the importance of the monetary valuation of negative environmental impacts in order to determine the true price of wood products to take informed investment decisions. This study aims to assess economic and environmental performance of five maritime pinewood products during the gate-to-gate process (harvesting to semifinal product) in the Landes de Gascogne Forest (“Landes Forest”) in the Nouvelle-Aquitaine region of France. The product groups considered are construction wood, pulp, plywood, pellets and pallets. For this purpose, the study uses several systemanalytical methods in combination: material flow analysis (MFA), life-cycle assessment (LCA), life cycle costing (LCC) and material flow cost accounting (MFCA). The relevant MFA data in Chapter 3 was collected from an industrial partner and based on databases, literature sources and other references to obtain Life Cycle Inventories for the LCA study in Chapter 4. The LCA software SimaPro was used for this analysis, applying the ReCiPe life-cycle impact assessment method to identify the environmental impact (gate-to-gate) of the studied products. A cost model based on the Environmental Prices Handbook was developed in Chapter 5 to estimate the external costs based on the environmental impact results. This has been set for each product group and integrated into environmental LCC to compare the external with the internal costs, in far as possible with the data available. The methodologies have been tied together in Chapter 6 using MFCA; results correspond to the market share specified in Chapter 3 by MFA. We found that, among the studied products, unbleached pulp and plywood production have the highest economic and environmental costs at €32.36/€15.13 and €27.22/€7.14, respectively. That means that the best use of raw timber is as construction wood due to two reasons: first, the long lifespan of construction wood compared to other studied products; second, not only is less energy is required in the production process, but chemical materials are also absent from the process. This study proposes a suitable methodology framework for the economic and environmental assessment of forest products and other industries. Moreover, this work reviews the design and monitoring of wood from a sustainable resource and environmental impact perspective The environmental impacts costs (external costs or externalities) and key internal costs have been estimated for studied product groups.

A study of the DUPIC (Direct Use of Spent PWR Fuel In CANDU) cycle was made to analyze cycle performance relative to that of PWR and CANDU fuel cycles in terms of uranium utilization and spent fuel production efficiency. The DUPIC cycle was found to be most efficient in terms of minimizing spent fuel production as well as most efficient (within limits) in terms of maximizing natural uranium utilization. It was found minimally productive to change PWR fuel management practices in order to extend burnup in the CANDU portion of the cycle. A policy analysis regarding potential implementation of the DUPIC cycle in North America, between the U.S. and Canada, was also made. CASMO computer models of PWR, CANDU, and CANFLEX fuel assemblies were created and benchmarked. The PWR models were then used to develop analytical correlations that predict PWR spent fuel isotopic compositions. Correlations that predict reactivity gain and burnup increase in CANDU reactors due to AIROX processing of PWR spent fuel were created. An estimate of fission product removal fractions during AIROX processing was developed. An integrated model that predicts CANDU discharge burnup extension due to the use of spent PWR fuel and AIROX processing was completed and used to analyze and compare the DUPIC cycle to other fuel cycles. The potential issues involved in implementation of a DUPIC cycle between the U.S. and Canada were examined. Stakeholders and influential groups were identified and their values were projected. A significant unresolved issue centers around which nation assumes custody of the DUPIC spent fuel and the disposal costs of that fuel. A plan for DUPIC cycle implementation was developed.

Full textA collaborative approach to industry-environment issues is acknowledged as a key aspect of sustainable development. Sincerely, resource sharing among firms offers the potential to increase stability of operations, especially in supply-constrained areas, by ensuring that access to important inputs such as water, energy and raw materials are guaranteed. Industrial Symbiosis (IS), a sub-field of Industrial Ecology, is primarily concerned with the cyclical flow of resources through networks of industrial units as a means of cooperatively approaching environmentally sustainable industrial activity. In line with this principle, a critical assessment of the change in environmental performance brought about by industrial symbiosis (IS) was conducted in nineteen selected eco-industrial park case studies identified in all regions of the world with the exception of the African continent. Case study selection criteria were based on models of eco-industrial parks proposed by Chertow (2000). A description of the type of material exchanges that go on in each case study was carried out which revealed evidence of implemented synergies in respective case studies. A comparative assessment of cross-case patterns which is a semi-quantitative matrix used to quantify the degree of environmental performance showed that there was a clear evidence of improved environmental performance among respective case studies investigated where water, energy and material flows served as indicators. Results obtained from the study showed a common pattern of industrial presence in respective case studies reflecting the occurrence of heavy process industries such as oil refineries, cement industries, petrochemical industries, and steel industries. The principle of “anchor tenant” proposed by some experts in the field of industrial ecology was strongly supported by the obtained results. Symbiotic cooperation among participating firms in respective case studies were mainly on areas like cogeneration, re-use of materials, recycling and wastewater treatment and re-use.

Full textNegli ultimi decenni, l’ambiente è stato al centro di un crescente interesse tra regolamentatori, media e comunità internazionali. In tale contesto, le aziende si sono ritrovate ad affrontare la questione ambientale attraverso lo sviluppo di strategie e l’implementazione di pratiche atte a ridurre l’impatto inquinante, l’uso di risorse e, in generale, ad accrescere la propria efficienza in ottica green. La presente tesi di dottorato ha lo scopo di analizzare congiuntamente la questione ambientale e le operations. Questo tema è particolarmente interessante perché prende in considerazione le fabbriche, ovvero le principali responsabili di inquinamento, allo scopo di investigarne le scelte e le azioni ambientali nell’ambito della strategia manifatturiera. La tesi è formata da tre articoli, ognuno dei quali corrisponde ad un capitolo. Il primo tratta della questione ambientale partendo da una prospettiva generale e definendo qual è il ruolo della strategia ambientale e quali sono i fattori determinanti per accrescerne la proattività; il secondo considera l’aspetto ambientale come una possibile priorità competitiva e cerca di individuare i fattori legati alle caratteristiche dell’azienda che incidono su una strategia manifatturiera orientata alla protezione dell’ambiente; infine, l’ultimo capitolo esplora il processo di implementazione di pratiche lean e green nelle fabbriche e l’effetto che questo produce sulle performance. In particolare, il primo capitolo analizza il concetto di strategia ambientale proattiva (SAP). La letteratura ha definito questa strategia come un insieme di pratiche volontarie che non si limitano ad applicare le norme in materia ambientale. Allo scopo di formulare una puntuale definizione, dapprima identifico le dimensioni di SAP: una dimensione tecnica e organizzativa e una dimensione di intensità relazionale. Secondo, propongo una struttura teorica che permetta di individuare differenti tipologie di strategia ambientale. Infine, provo a delineare le spinte dinamiche che sono alla base dei cambiamenti tra una tipologia di SAP e l’altra. In questo modo, metto in evidenza che la strategia ambientale proattiva è multidimensionale e che non può essere definita univocamente, rendendo pertanto opportuno capirne il ruolo all’interno della strategia aziendale. Il secondo capitolo affronta il tema dell'ambiente naturale nell'ambito della strategia manifatturiera delle aziende. In particolare, lo scopo è analizzare gli effetti del contesto organizzativo sull'enfasi che i managers pongono sulla priorità ambientale con rispetto alle tradizionali priorità competitive di costo, qualità, consegna, flessibilità e innovazione. Grazie a una regressione logistica multinomiale, indago la relazione tra il contesto organizzativo, espresso in termini di caratteristiche dell'azienda e della catena di fornitura, e tre diverse possibili strategie manifatturiere: strategia orientata al sostegno ambientale; strategia orientata alla riduzione dei costi; e strategia con simile enfasi su tutte le priorità competitive. L'analisi empirica si basa su un campione di aziende manifatturiere canadesi operanti nei settori dei metalli, dei macchinari, dell’elettronica e delle apparecchiature elettroniche. I risultati dell'analisi evidenziano che il contesto organizzativo influisce sull'enfasi che i managers decidono di dare alla sostenibilità ambientale. Infatti, essi mostrano che quanto più la catena di fornitura si estende internazionalmente, ovvero i clienti e i fornitori sono dispersi in diverse aree geografiche, tanto più l'azienda adotta una strategia manifatturiera che pone enfasi sulla protezione dell'ambiente naturale. Questo è probabilmente motivato dal fatto che un'azienda ha maggiore difficoltà a controllare i potenziali rischi ambientali causati dai propri stakeholders operanti in diverse aree geografiche, dai quali possono derivare sanzioni pecunarie su pezzi importati non conformi alle norme e/o un danno alla propria visibilità a livello globale. L’ultimo capitolo affronta il tema della gestione ambientale da una prospettiva esclusivamente operativa. Nello specifico, questo articolo contribuisce a esplorare come le pratiche di lean management e le pratiche di green management possono essere implementate insieme per migliorare la competitività. La relazione tra lean manufacturing e performance ambientale da un lato, e tra gestione ambientale e performance operativa dall’altro, è stata ampiamente studiata ma senza arrivare a una visione univoca dei benefici che ne derivano. Tuttavia, un certo numero di ricerche hanno mostrato che alcune pratiche di lean e green sono complementari. Basandosi sulla metodologia dello studio di caso, il presente articolo ha lo scopo di capire come i due insiemi di pratiche interagiscono tra di loro e producono effetti sulle performance operative e ambientali. Attraverso l’analisi di tre progetti di successo di due aziende italiane, identifico che il timing di implementazione, sequenziale vs simultaneo, definisce le modalità di gestione delle pratiche da adottare – pianificazione vs mutuo aggiustamento. Questo aspetto ha un effetto significativo sulle performance dell'azienda in quanto l'approccio simultaneo porta a risultati maggiori rispetto all'approccio sequenziale. Infine, l'analisi dei casi mi permette di individuare i drivers che influenzano la relazione tra pratiche green e lean nell'implementazione di progetti ambientali

Full textThis thesis examines what consequences, through which pathways, and under which circumstances, does country-level environmental policy evaluation, carried out by an intergovernmental organisation, have for institutional change towards sustainable development. The philosophical and theoretical frameworks of institutional economics are proposed as the lens through which to assess experiences from evaluation research. This is done in order to elaborate a conceptual framework for analysing the approach, the impact and the factors conditioning the influence of environmental policy evaluation in the context of sustainable development. The OECD Environmental Performance Review programme is examined through an in-depth qualitative case study approach. It is found that in spite of engendering relatively modest interest among the public, the reviews increase the legitimacy of environmental policies and authorities, and strengthen a performance-oriented environmental policy emphasising evaluation, monitoring and cost-effectiveness. These impacts operate through four parallel pathways, representing the purposes of learning and accountability. The type and intensity of influence depends on the capacity of the reviews to mobilise key change agents and to be sensitive to the context, as well as on the credibility and political weight of the OECD in the reviewed country. It is concluded that notwithstanding the distance of the prevailing OECD conception of sustainability from the institutionalist principles adopted as the benchmark for the appraisal in this thesis, the reviews contribute meaningfully to sustainable development by redressing asymmetries of power, thereby improving some of the conditions for deliberative democracy

Full textPorts are links that connect the inland transport to maritime transport and are essential for international trade. Because of its importance to the development of countries, ports are demanding improved techniques for their management and for evaluating their performance. In this context, there are important issues such as the definition, usable metrics and also dimensions of performance to be evaluated. One important question is the environmental performance of the port. Ports impact both on maritime and inland ecosystems, and it is necessary to minimize these impacts. However, the environmental assessment usually involves technical variables, and economic and financial impact are not taken into account. Thus, this dissertation proposes to understand the issues involved in assessing the performance of ports, and specifically in environmental performance evaluation on them. For this, an exploratory research was carried out aiming to understand the environmental performance evaluation issue taking into account economic and financial aspects. Throughout this study, the results showed that there was still a gap in the literature, where there was not a model to take into account economic and financial criteria to evaluate environmental performance. To solve this problem, a model with indicators to evaluate the performance was proposed. However, to assess the implementation feasibility of the proposed model, interviews were held with stakeholders in the port sector. Respondents were Environmental Management Sector of ANTAQ (National Agency of Waterway Transportation), SEP/PR (Special Secretariat of Ports of Precidency of Republic) and two Superintendents of Rio Grande do Sul, which are responsible for public ports in the state: SPH (Superintendence of Ports and Waterways) and SUPRG (Superintendence of Port of Rio Grande). The results of the interviews show that the proposed model would not apply at this time. So the proposal was adapted and created a simplified model and one that can be deployed when there is already sufficient database. Therefore, the academic contribution of this study is related to the establishment of indicators for measuring the environmental and economic performance in ports and the subject of discussion for Brazilian ports.

Full textEn l'actual situació de l'energia, amb un pronosticat augment del consum energètic en un context d'esgotament dels combustibles fòssils, s'està posant més atenció en les fonts d'energia renovable per generació elèctrica. Per millorar el seu desplegament arreu, els sistemes híbrids d'energia renovable són una alternativa en puixança, donat que aquests poden aprofitar l'escalabilitat i flexibilitat de les fonts d'energia renovable donat que la combinació de dues o més fonts permet contrarrestar les debilitats d'una font d'energia no controlable amb les fortaleses d'una altra o amb la controlabilitat d'una font d'energia no renovable. Aquest treall presenta una metodologia d'optimització que ha estat desenvolupada per a optimització del cost de cicle de vida i per la optimització multi-objectiu de cost i impacte ambiental (IA) de cicle vida d'un sistema híbrid d'energia renovable connectat a la xarxa elèctrica i basat en l'ús de les energies solar fotovoltaica (FV), eòlica i de la biomassa. En aquest sistema l'ús de la biomassa busca l'aprofitament del recurs forestal autòcton en forma de 'wood chips' per proporcionar energia en aquells períodes en els què les energies FV i eòlica no són suficients per a subministrar la demanda existent i, addicionalment, produïr energia tèrmica adoptant un esquema de cogeneració. El model desenvolupat ha estat testat i validat en un municipi rural situat a la Catalunya central i utilitzant dades reals de velocitat de vent, irradiació solar i demanda elèctrica amb una precisió horària. Per a evaluar diferents situacions i disposicions del sistema, s'han dut a terme 4 casos d'estudi, i el model ha estat adaptat a cada una de les situacions analitzades. També s'han dut a terme anàlisis de sensibilitat que permeten detectar a quines variables és més sensible el model i el sistema de producció elèctrica. En tots els casos, el model respon adequadament als canvis implementats en les dades d'entrada, a la vegada que proporciona resultats del dimensionat òptim del sistema. Fixant-nos en un sistema FV - eòlic, els resultats de la seva optimització de cost mostren que seria econòmicament viable la seva instal·lació en la localització evaluada, amb un període de retorn de la inversió de 18 anys dels 25 anys de vida útil del sistema. Si ens fixem en un sistema FV - eòlic - biomassa, els resulstats mostren que el sistema requereix de menys inversió inicial que l'anterior, avantatge contrarrestat per un cost de cicle de vida major. No obstant, aquest sistema aportaria beneficis en termes d'autonomia energètica, millora de qualitat ambiental i en creació de llocs de treball derivats del processat de la biomassa forestal, una font intensiva en demanda de llocs de treball. El mateix sistema també s'ha analitzat des d'una perspectiva multi-criteri, considerant també l'IA. En aquest cas, els resultats mostren que cost i impacte ambiental són criteris contradictoris: sistemes de baix IA tenen costs més elevats que aquells que se sustenten en l'energia de la xarxa elèctrica, que presenta un elevat IA. Els resultats també mostren que la millora de la taxa de retorn de la inversió seria una mesura molt beneficiosa per fomentar l'ús de les energies renovables per a la generació d'electricitat degut al seus retorns positius en termes de reducció de cost i IA. La darrera hipòtesi analitzada ha estat l'adopció d'un esquema de cogeneració. En aquest cas, el sistema mostra menors períodes de retorn de la inversió, fent-lo rentable a partir dels 10 anys. Això es deu a la utilització de l'energia tèrmica produïda en la valorització energètica de la biomassa, que té efectes en la millora de l'eficiència al aprofitar energia que d'altra manera es malbarata. Els balanços entre cost i impacte ambiental mostren de nou que petites inversions en energia renovable tenen grans retorns en termes de reducció de l'IA, en especial partint d'un sistema elèctric on més d'un 50% de fonts energètiques són combustibles fòssils amb elevat IA

Full textCirkulära affärsmodeller kan hjälpa till att omforma och övergå från det nuvarande linjära konsumtionsmönstret, vilket i sin tur kan göra det möjligt för oss att uppnå en cirkulär ekonomi. Företag kan ändra sin driftsmodell och överväga ett mer hållbart alternativ till sin nuvarande produktions- och konsumtionsmetod. För att företag ska bistå vid övergången till cirkulär ekonomi kan strategierna för cirkulär ekonomi integreras i deras affärsmodeller. Företag har redan börjat anpassa sina mål för att uppnå detta genom att mäta prestationsindikatorer. Key Performance Indicators (KPI) används för att effektivt kommunicera och sätta upp mål som ska uppnås inom olika nivåer i en organisation. KPIs kan användas för att övervaka utvecklingen av olika aspekter av hållbarhet, inklusive miljö, ekonomisk och social. Av denna anledning övergår många branscher mot en cirkulär affärsmodell för att säkerställa bättre resursutnyttjande och hållbara operationer. Prestandamätning är avgörande för att företag ska kunna utvärdera sina framsteg i förhållande till sina uppsatta mål. I denna studie har relevanta befintliga cirkulära KPIs identifierats som kan implementeras av fallstudieföretagen för att mäta prestanda för deras försörjningskedja och hela affärsmodellen. Fokus för denna studie är de tekniska, miljömässiga och socioekonomiska dimensionerna samtidigt som de viktigaste prestationsindikatorerna identifieras. En systematisk litteraturöversikt utfördes initialt under denna studie. Data erhållen från litteraturen jämfördes därefter med empiriska data. De empiriska uppgifterna är baserade på intervjuer och undersökningar som gjorts med fallstudiebolagen som senare sammanställdes för att utveckla lämpliga indikatorer.
