Fruit of the photosynthesis of plants, the biomass is an essential resource for humans, supplying them with food, energy and materials. With its three sources (forest, crops and waste), the energy-biomass is restricted by the production capacity of soils and its competition with its other uses. Could it therefore contribute to the growing energy needs of humanity and to the energy transition that must take place to reduce our oil and gas consumption substantially?
How will waste management be organised in the years to come?What are the conflicts between the population and the decision makers? What are the decisive economic factors?

They present the historic, sociological, economic and health components that go hand in hand with territorial waste management and the use of technologies in France.
The Calanques National Park has been a project since the 1970s, but has now become official by decree in April 2012. It is the first second-generation national park (law of 2006).Given that it is coastal and located at the gates to Marseille, a city with a population of two million, its creation has crystallised crucial ecological and social issues. How can we define its borders at the scale of "natural" urban areas involved? How can we protect the biodiversity whilst preserving the cultural heritage? This book retraces the construction of the project by focusing on the consultation period involving all the stakeholders (economists, politicians, residents, users, etc.).

After a review of the basic elements concerning activated sludge biology and its visual observation, detailed data profiles for all of the major species encountered are presented with ample illustrations and/or colour photos. These profiles, easily accessible using the identification keys, by alphabetical order or a simplified classification system, are enhanced by an "interpretation" section designed to help treatment station operators to more clearly understand how the plants operate. Annexes with very practical methodological advice and examples of sludge interpretation are included.
Media and politicians alike are spending more and more time on debating energy issues.
