This paper deals with the use of simplified methods to predict methane generation in tropical landfills.Methane recovery data obtained on site as part of a research program being carried out at the Metropol-itan Landfill, Salvador, Brazil, is analyzed and used to obtain field methane generation over time. Labora-tory data from MSW samples of different ages are presented and discussed; and simplified procedures toestimate the methane generation potential, Lo, and the constant related to the biodegradation rate, k areapplied. The first order decay method is used to fit field and laboratory results. It is demonstrated thatdespite the assumptions and the simplicity of the adopted laboratory procedures, the values Lo and kobtained are very close to those measured in the field, thus making this kind of analysis very attractivefor first approach purposes.

Egypt reviews Red Sea waste management system – Dailynewsegypt
Egypt’s Minister of Local Development and Environment, Manal Awad, and Red Sea Governor Walid El-Barqi held an extensive meeting to review the performance of the governorate’s waste management system and discuss measures to improve environmental services and operational efficiency. The meeting, held during Awad’s visit to the Red Sea Governorate to mark World Environment Day, focused on assessing current challenges facing waste collection, sorting, recycling and disposal operations, as well as identifying priority actions to strengthen the system’s performance. Awad stressed that the government places significant importance on developing an integrated waste management system in the Red Sea Governorate, given its strategic importance as one of Egypt’s leading tourism destinations. She emphasized the need to comply with environmental and technical standards governing sanitary landfills, waste treatment facilities and environmentally sound disposal practices. During the meeting, officials reviewed the current status of waste management operations in Hurghada, including collection, transportation, sorting, recycling and final disposal activities. Discussions also covered the infrastructure upgrades required to improve system efficiency and ensure the proper operation of sanitary landfill facilities. Yasser Abdullah, head of Egypt’s Waste Management Regulatory Authority, presented updates on temporary waste collection and sorting sites and outlined measures to strengthen operational management and oversight. He highlighted the importance of improving monitoring mechanisms for waste handling activities and maximizing the recovery of recyclable materials while reducing informal and unregulated practices.
