Waste Management is one of the key problems of modern society due to the ever-expanding volume and complexity of discarded domestic and industrial waste.Society is increasingly aware of the need to establish better practices and safer solutions for waste disposal. This requires further investigation into disposal methods and recycling as well as new technologies to monitor landfills, industrial mining wastes and chemical and nuclear repositories.This creates a need for more research on current disposal methods such as landfills, incineration, chemical and effluent treatment, as well as recycling, clean technologies, waste monitoring, public and corporate awareness and general education.Unfortunately, many of the policies adopted in the past were aimed at short term solutions without due regard to the long term implications on health and the environment, leading in many cases to the need to take difficult and expensive remedial action.The desired direction of Waste Management is towards sustainable strategies. The approach that has emerged as the most promising has been called 4Rs, where reduction, reuse, recycling and recovery are seen as the best actions. This largely decreases the volume of waste that needs final disposal. Recovery refers to the establishment of two new classifications, those of Secondary Raw Materials (SRM) and of Refuse Derived Fuel (RDF). They both relate to useful products obtained from waste and make a shift from the mere recycle or reuse – mostly seen as a way to reduce dumping – to the valuable employment of such matter within the production cycle.Another aspect of this revolution is happening subtly and gradually by people buying waste; particularly eWaste and some types of plastic, the so-called technical waste. This is happening due to the strong demand and high price of certain new materials and the possibility of sorting out waste in developing regions of the world. As a result, a market in Secondary Raw Materials (SRM) has developed.Covering various areas under the topic of Waste management, this volume contains a selection of papers presented at the 10th International Conference on Waste Management and the Environment.

Today, tourism is an important component of development, not only in economic terms but also for knowledge and human welfare. Tourism today is an activity accessible to a growing number of people.The phenomenon has many more advantages than disadvantages. New forms of economic development and increasing wealth of human societies depend on tourism. Our knowledge of the world now includes a strong component due to tourism. Human welfare has physiological and psychological elements, which tourism promotes, both because of the enjoyment of knowing new territories and increasing contacts with near or far away societies and cultures.The tourism industry has nevertheless given rise to some serious concerns, including social costs and ecological impacts. Many ancient local cultures have practically lost their identity. Their societies have orientated their economy only to this industry. Both the natural and cultural – rural or urban - landscapes have also paid a high price for certain forms of tourism. These problems will persist if the economic benefit is the only target, leading to economic gains that eventually become ruinous. It is also important to consider that visitors nowadays are increasingly demanding in cultural and environmental terms.Never before have transport and communication links been so important as today. Natural ecosystems are now a rarity on the planet and ecologists talk today about ‘socio-ecosystems’. Given this, tourism and environmental education are facing a major challenge.The 9th International Conference on Sustainable Tourism had the aim of finding ways to protect the natural and cultural landscape through the development of new solutions which minimise the adverse effects of tourism. A selection of the papers presented at the meeting form this volume.
