Abstract

The book points out that rural regions need proper attention at the global level concerning solid waste management sector where bad practices and public health threats could be avoided through traditional and integrated waste management routes. Solid waste management in rural areas is a key issue in developing and transitioning countries due to the lack of proper waste management facilities and services. The book further examines, on the one hand, the main challenges in the development of reliable waste management practices across rural regions and, on the other hand, the concrete solutions and the new opportunities across the world in dealing with municipal and agricultural wastes. The book provides useful information for academics, various professionals, the members of civil society, and national and local authorities.

Abstract

Rapid population growth, high standards of living, and technological development are constantly increasing the diversity and quantity of solid waste. The production of solid municipal waste associated with the high proportion of organic waste and its improper disposal lead to considerable environmental pollution due to the emission of greenhouse gases such as methane, carbon dioxide, etc. In such a challenging environment, municipal authorities need to develop more effective solutions to manage the growing urban solid waste. Most of the municipal solid waste mainly constitutes degradable materials, which represent a significant role in greenhouse gas emissions in urban localities. Integrated solid waste management approaches must be developed and improved to manage the increasing organic fractions of municipal solid waste, which helps to reduce greenhouse emissions with potential economic benefits. A sustainable management of municipal solid waste systems constitutes a promising and attractive trend to study current consumption behaviors responsible for waste generation, and to protect the global ecosystem. This book presents the management of municipal of solid waste, including recycling and landfill technologies. Moreover, composition and types of waste will be investigated. As a result, the most appropriate and feasible scenarios for the management of municipal solid waste are presented to provide the respected readership with the scientific background for sustainable development in these processes, which are increasingly supported by innovative methodologies for holistic assessment of process sustainability.

Abstract

Anaerobic digestion of the organic fraction of municipal solid waste as such or together with food waste, press water or patatoes sludge was investigated to equilibrate methane production within a day or over the weekend, when no OFMSW was available. A stable co-digestion process could be achieved with COD degradation between 60 and 80 %. The max. organic loading rates were 28 kg COD/L,d. For stable methane production the OLR during Co-digestion should not excede 22,5 kg/L,d.

Abstract

Compared to conventional chemical technologies and other similar industrial processes, bioprocesses represent a more sustainable and environmentally-friendly alternative for the production of fuels and platform chemicals. In biorefineries, different kinds of feedstocks, such as biomass or lignocellulosic materials in general, can be used and fermented by microorganisms (e.g., bacteria, fungi, algae), after some pretreatment steps, to produce high added-value metabolites. More recently, wastes, wastewaters and also waste gases have been shown to be suitable for resource recovery or for their bioconversion to (bio)fuels (e.g., ethanol, butanol, hexanol, biodiesel, biohydrogen, biogas) or other commercial products (e.g., biopolymers). In this sense, much effort has also been made to bioconvert greenhouse gases, such as CO2, into useful products.The goal of this Special Issue is to publish both recent innovative research data, as well as review papers on the fermentation of different types of substrates to commercial (bio)fuels and (bio)products, mainly focusing on the bioconversion of pollutants in solid, liquid, or gas phases (wastes, wastewaters, waste gases).

Abstract

Après une quinzaine d’années de reconstruction dans un climat de paix relative, de 1990 à 2004, le Liban a connu depuis 2005 une succession d’épisodes politiques violents mêlant de manière complexe enjeux internes et tensions régionales. Le déclenchement de la crise syrienne et ses retombées politiques, économiques et démographiques sur le Liban accentue cet état de fait. Cet ouvrage met en lumière ces nouveaux défis et complète en intégrant des volets différents l’analyse des transformations libanaises déjà entreprises dans l’Atlas du Liban. Territoires et société publié en 2007 par la même équipe. Outre la crise internationale et les mouvements de population, il prend en compte les dimensions socio-économiques à l’intérieur du Liban, les problématiques environnementales liées à l’urbanisation incontrôlée et aux risques, ainsi que la gestion territoriale et les conflits locaux qu’elle suscite. Cet atlas est le fruit d’une collaboration entre des chercheurs et universitaires français et libanais. Il utilise une approche géographique, plaçant au premier plan de l’analyse la spatialisation des faits sociaux et naturels. Les sources publiques sont limitées, notamment du point de vue de la finesse géographique, parfois peu fiables et difficiles d’accès. C’est particulièrement vrai pour les données sur la population libanaise, moins bien connue que la population réfugiée. Les données internationales permettent de situer le Liban par rapport à ses voisins. Des données thématiques, issues des ministères, offrent néanmoins une vision détaillée pour certains domaines. L’analyse d’images aériennes et de satellites fournit des données essentielles sur l’urbanisation et l’environnement. Des enquêtes de terrain localisées et thématiques complètent la panoplie des informations utilisées. L’ouvrage comprend six chapitres. Le premier porte sur la géopolitique régionale, les violences politiques internes et leurs effets locaux, à savoir l’installation des réfugiés syriens et la réémergence au grand jour des milices et groupes armés en conflit entre eux et avec l’armée libanaise. Le Liban apparaît de nouveau comme un territoire fragmenté entre de multiples allégeances. Le deuxième chapitre montre la fragilité du modèle économique libanais. Sa dépendance aux investissements extérieurs et aux remises de la diaspora, les blocages de l’industrie et de l’agriculture aggravent les déséquilibres sociaux. Le troisième chapitre est un bilan de l’urbanisation du pays, qui s’est accrue en superficie de 80% en vingt ans, au détriment des espaces naturels et de l’agriculture. Le littoral, objet d’intenses convoitises, est largement artificialisé et dégradé. De multiples signes de mutations et de dégradation de l’environnement sont observables sur le territoire libanais et sont l’objet du quatrième chapitre. Certains semblent annonciateurs du changement climatique global et de ses effets locaux. En outre, il existe un lien direct entre l’urbanisation massive et de nombreux risques mesurés et cartographiés de plus en plus clairement. Le chapitre cinq se concentre sur les dysfonctionnements de quelques services publics en lien avec l’exploitation des ressources naturelles : l’approvisionnement en eau, en énergie, tous deux marqués par la pénurie, et la gestion des déchets solides, qui traverse une crise profonde. Le sixième chapitre étudie les mutations dans la gestion du territoire libanais, marqué par le retrait voire la marginalisation de l’État et l’affirmation d’autres acteurs agissant sur le territoire, notamment les municipalités, les pouvoirs locaux mais aussi des associations de la société civile.

Abstract

After fifteen years of reconstruction in a relatively peaceful environment spanning the years 1990 to 2004, Lebanon has experienced successive violent political events resulting from complex entangled internal and external struggles. The Syrian crisis and its political, economic and demographic consequences on Lebanon have increased these tensions. This atlas sheds light on these new challenges and adds new data that complete the analyses already published in the Atlas du Liban. Territoires et société (Atlas of Lebanon. Territories and Society) released in 2007 by the same research team. Some of its components are included in this edition. Beyond the international regional crisis and the population movements, it takes into account Lebanon’s socio-economic dimensions, the environmental issues linked to uncontrolled urbanization and to natural risks, as well as conflicts due to local territorial management. This atlas is the result of a collaborative endeavor between French and Lebanese researchers. It uses a geographical approach that puts in the foreground a spatial analysis of social and natural phenomena. Public sources are scarce in Lebanon, especially at the local scale. They are sometimes less reliable and difficult to access. It is particularly the case for the Lebanese census data, conversely data are abundantly available on the refugees population, which is less known than the population of refugees. International data help compare Lebanon to its neighbors. Thematic data produced by some ministries are helpful to provide a detailed view regarding specific domains. Analyses processed on aerial and satellite images have produced essential data on urbanization and environment. Local thematic fieldwork surveys have provided additional data. The book consists of seven chapters. The first one deals with the territorial state-building seen in the light of regional geopolitics, and emphasizes internal violence and the reemergence of militias and armed groups that fight each other and the state army. Lebanon is once again perceived as a territory divided between multiple allegiances. The second chapter is devoted to the analysis of population dynamics, despite the lack of reliable data whose sources are subject to discussion. It includes analyses of internal population flows, the Lebanese diaspora, and the assessment of Syrian refugees’ influx. The third chapter shows the fragility of the Lebanese economic model. Its dependency on foreign investments and on the remittances of the diaspora, as well as the deadlocks of industry and agriculture, which aggravate social imbalances. The fourth chapter is an assessment of urbanization in the country, which has increased by 80% in surface in twenty years at the expense of natural spaces and agriculture. The shore is highly coveted and widely artificialized and damaged. Multiple signs of environmental degradation are examined in chapter five. They seem to announce the global climate change and its local effects. In addition to that, there is a direct link between massive urbanization and many risks, measured and mapped in an increasingly detailed way. Chapter six tackles the dysfunctional public services that exploit natural resources: water and energy supply, both marked by massive shortages, and the management of solid waste hit by a serious crisis. The seventh and last chapter studies the mutations of the local territorial management, which is marked by the retreat of the state, if not its marginalization, and the rise of other actors, notably municipalities, local powers and also civil society organizations.After fifteen years of reconstruction in a relatively peaceful environment spanning the years 1990 to 2004, Lebanon has experienced successive violent political events resulting from complex entangled internal and external struggles.

Abstract

Throughout the world religious organizations are exploring and implementing into action ideas about the relevance of religion and spirituality in dealing with a growing multitude of environmental issues and problems. Religion and spirituality have the potential to be extremely influential for the better at many levels and in many ways through their intellectual, emotional, and activist components. This collection focuses on providing a set of captivating essays on the specifics of concrete cases of environmental activism involving most of the main Asian religions from several countries. Particular case studies are drawn from the religions of Animism, Buddhism, Daoism, Hinduism, Islam, and Jainism. They are from the countries of Bhutan, China, India, Indonesia, and Thailand. Thereby this set of case studies offers a very substantial and rich sampling of religious environmental activism in Asia. They are grounded in years of original field research on the subjects covered. Collectively these case studies reveal a fascinating and significant movement of environmental initiatives in engaged practical spiritual ecology in Asia. Accordingly, this collection should be of special interest to a diversity of scientists, academics, instructors, and students as well as communities and leaders from a wide variety of religions, environmentalism, and conservation.

Abstract

The extraction of apatite minerals is becoming more and more crucial with the depletion of high-grade ores. At the same time, many streams of waste are continuously being produced by the phosphate industry, including calcareous and siliceous waste rocks, clayey sludge and phosphogypsum. These waste products are produced in huge volumes reaching a ratio of between 5 to 10 tons of waste per each ton of concentrated phosphate. The management of these waste products is becoming a real issue in terms of growing public awareness and environmental and financial aspects. In addition, phosphate ores are known to contain other critical raw materials (CRM) such as rare earth elements and uranium. The recovery of these vital elements from phosphate waste may help to develop the needs of the green energy of the future and contribute to the achievement of the sustainable development goals. In this Special Issue, insights related to the following aspects were studied: phosphate extraction and beneficiation, novel phosphate ores, the fine characterization of phosphate ores and waste, phosphoric acid production, critical raw material (CRM) recovery from phosphate ores and waste, reprocessing of phosphate wastes and finally the valorization and reuse of phosphate waste and phosphogypsum.

Abstract

The energy and fuel industries represent an extensive field for the development and implementation of solutions aimed at improving the technological, environmental, and economic performance of technological cycles. In recent years, the issues of ecology and energy security have become especially important. Energy is firmly connected with all spheres of human economic life but, unfortunately, it also has an extremely negative (often fatal) effect on the environment and public health. Depletion of energy resources, the complexity of their extraction, and transportation are also problems of a global scale. Therefore, it is especially important nowadays to try to take care of nature and think about the resources that are necessary for future generations. For scientific teams in different countries, the development of sustainable and safe technologies for the use of fuels in the energy sector will be a challenge in the coming decades
