Biological treatment of wastewater is a low-cost solution for remediation of wastewater. This book focuses on the bioremediation of wastewater, its management, monitoring, role of biofilms on wastewater treatment and energy recovery. It emphasizes on organic, inorganic and micropollutants entering into the environment after conventional wastewater treatment facilities of industrial, agricultural and domestic wastewaters. The occurrence of persistent pollutants poses deleterious effects on human and environmental health. Simple solution for recovery of energy as well as water during biological treatment of wastewater is a viable option. This book provides necessary knowledge and experimental studies on emerging bioremediation processes for reducing water, air and soil pollution.

Geomaterials derived from the Earth’s crust and used in construction after appropriate processing are among the earliest raw materials exploited, processed and used by humans. Their numerous functional properties include accessibility, workability and serviceability, and these are explored within this volume. In modern society, sustainable use of raw materials, specifically those exploited in large volumes such as geomaterials for construction, raises questions of reducing extraction of primary resources and thus minimizing impacts on natural systems, and also employment of materials and technologies to lower emissions of deleterious substances into the atmosphere. This will be possible only if we fully understand the properties, processing and mode of use of traditional geomaterials. Although most of the papers within this volume were written by geologists, the contributions will also be of interest to those working in cultural heritage, monument conservation, civil engineering and architecture.

The problems recyclers face with wastepaper are connected to the issues addressed by forest advocates, as well as to the difficulties confronted by those involved with industrial pollution from the paper industry. In this richly detailed study, Maureen Smith shows how industrial and environmental analysis can be synthesized to clarify these complex problems and produce solutions. Smith outlines the basic structural characteristics of the U.S. pulp and paper industry and its relationship to the larger forest products sector, as well as its patterns of domestic and global fiber resource use. She then reviews the core technologies employed in virgin pulp production, with an emphasis on their environmental impacts, the role of technological innovation, and the relationships between fiber choices and pollution prevention. Building on this base she reveals structural barriers within the industry that have impeded positive change and shows how these barriers are reinforced by the traditional isolation of environmental policy domains.The study includes a comparative analysis of how organochlorine pollution from pulp mills has been addressed in the United States, Europe, and Canada (and why the United States has seen the slowest rate of progress); an assessment of commodity trade patterns in the industry and how they are linked to resource demand; an examination of the momentum building around annual plant fiber use and the diverse interests it reflects; and a review of recent developments in paper recycling within the context of historical trends in fiber utilization. A case study of the controversial environmental review process of the largest recycled pulp and paper mill ever proposed ties together earlier elements of the book and forms the basis for the conclusions. In closing, Smith argues convincingly against narrowly focused attempts to "fix" the problems associated with the industry, and offers practical guidance on new frameworks and approaches for industrial restructuring. She highlights the need for regional perspectives that integrate environmental, social, and economic objectives. Urban and Industrial Environment series

With globalization fast becoming an irreversible process, it is necessary to pay increased attention to the implications for environmental sustainability. However, the so-called environmental Kuznets curve (EKC) argument implies that rapid economic growth in many developing countries should be environmentally unsustainable. Environmental Sustainability addresses this dichotomy and articulates a notion of consumption sustainability that is both universal and pertains to the indefinite future. Additionally, it emphasizes the importance of addressing a broad spectrum of sources of environmental degradation and relates this measure to an index of economic achievement more complete than per capita income. As well as the EKC, authors Jha and Murthy also critique the Environmental Sustainability Index (ESI) and empirically substantiate the proposition that a certain type of development in the presently high-income countries is primarily responsible for global environmental degradation. Several policy conclusions for global environmental management are also advanced. Throughout, Jha and Murthy comprehensively evaluate existing approaches to environmental sustainability and critically review empirical studies of environmental degradation, and economic development, making this an invaluable source of information for those concerned with environmental economics and political economy.

Environmental issues are of fundamental importance, and a broad approach to understanding the relationship of the human economy and the natural world is essential. In a rapidly changing policy and scientific context, this new edition of Environmental and Natural Resource Economics reflects an updated perspective on modern environmental topics. Now in its fourth edition, this book includes new material on climate change, the cost-competitiveness of renewable energy, global environmental trends, and sustainable economies. The text provides a balanced treatment of both standard environmental economics and ecological economics, based on the belief that these two approaches are complementary. Several chapters focus on the core concepts of environmental economics, including the theory of externalities, the management of public goods, the allocation of resources across time, environmental valuation, and cost-benefit analysis. Material on ecological economics includes such topics as macroeconomic scale, entropy, and "green" national accounting. Topical chapters focus on: energy; climate change; water resources; international trade; forests; fisheries; and agriculture, with an emphasis on designing effective policies to promote sustainability and a "green" economy. Harris and Roach’s premise is that a pluralistic approach is essential to understand the complex nexus between the economy and the environment. This perspective, combined with its emphasis on real-world policies, is particularly appealing to both instructors and students. This is the ideal text for classes on environmental, natural resource, and ecological economics.

On the bicentennial of Malthus' legendary essay on the tendency of population to grow more rapidly than the food supply, this book examines the impacts of population growth on 19 global resources and services, including food, fresh water, fisheries, jobs, education, income and health. Despite current hype of a 'birth dearth' in parts of Europe and Japan, the fact remains that human numbers are projected to increase by over 3 billion by 2050. Populations in rapidly growing nations are in danger of outstripping the carrying capacity of their natural support systems and governments in such situations will find it increasingly hard to respond to crises such as AIDS, food and water shortages and mass unemployment. Beyond Malthus examines methods such as the expansion of international family planning, investment in educating young people in the developing world and promotion of a shift towards smaller families which will represent the most humane response to the possible ravages of the population explosion.

This report addresses the role of forest products in replacing fossil-based and GHG-intensive products. The overarching objective is to provide recommendations to strengthen the contribution of substitution by forest products to sustainable development. To that end, this report firstly provides an overview of the understanding of the bioeconomy and the role of forest products across the world. Secondly, we present examples of conventional and innovative forest products and describe their role in the bioeconomy. Thirdly, we present a review of the quantitative and qualitative understanding of the environmental impacts and benefits of substituting fossil fuel-based or -intensive products with forest-based products, and of the contribution of substitution to SDGs. Fourthly, we outline the current understanding of the future global demand and supply dynamics of forest products and the potential impact that increased substitution may have on these dynamics. Fifthly, we identify gaps in the global forest product value chain. Finally, it provides recommendations and conclusions, respectively.
