In chapter one, Abdelhakim El Maguiri, Yassine Zegzouti, Salah Souabi, Laila Idrissi, Miloud El Hadek, and Mohamed Hafidi discuss result, initiatives in the cities of Meknes and Marrakech where the objective is to create compost production units from green waste and certain types of mixed organic waste for the amendment of agricultural land in their landfills. Afterwards, Okunola A. Alabi and Adekunle A. Bakare speak on the necessity for assessment of the potential DNA damaging effects of a new exposure scenario in chapter two. In chapter three, Hiroshi Asakura uses the ratio of oxygen flow rate by aeration to oxygen consumption rate of waste layer as a parameter to determine the reaction rate of organic matter in leachate from landfilled MSWI residue and incombustible waste. In chapter four, Dorota Kulikowska and Magdalena Zielińska discuss adsorption and membrane methods and their advantages and disadvantages. Next, Ratiba Irinislimane, Hanane Tounsi, Billel Malouadjmi, Saad Djediat, and Naima Belhaneche Bensemra present a study in chapter five wherein a count of microbial biomass is studied before and after respirometry in order to investigate the loss of mass. In chapter six, N. Lardjane and N. Belhaneche-Bensemra study the evolution of density and mechanical properties, with the results showing that the nature of the plasticizer and heat stabilizer affects the properties of PVC. In chapter seven, Mohamad Anuar Kamaruddin, Hamidi Abdul Aziz, Rasyidah Alrozi, and Mohd Hafiidz Jaafar discuss the fact that cooperation between public and the authorities in formulating suitable mechanisms is necessary for the attainment of integrated SWM goals. Following this, chapter eight by Dorota Kulikowska and Katarzyna Bernat present an overview of characteristics of landfill leachate from the perspective of biological nitrogen removal. In chapter nine, J. Faitlia, T. Magyarb, R. Romendac, A. Erdélyid, and C.S. Boldizsáre was to extract the decomposition heat from MSW landfills in order to study the processes. In the final chapter, Islam Safia Abdelli, Fatiha Abdelmalek and Ahmed Addou propose methodology for efficient waste management to improve the exploitation of S.L and concrete proposition of valorization channels based on the 3R-VE principle.
