The paper is concerned with the anaerobic co-digestion of wastewater treatment
plant sludge and organic waste coming from the fresh food department of a large market store
where a source separated collection system is installed. In particular the study is aimed to verify
by means of pilot plant operation if the reactor is able to work in stable conditions for
increasing organic loading rates due to the organic waste addiction – with respect to the
wastewater sludge simple digestion. In this way, different organic loading rates were tested,
which corresponded to different scenarios of organic waste feeding to the anaerobic digestion
plant. For the carried out experiments the pilot reactor showed a considerable improvement in
biogas production while the reactor working conditions remained stable. An economical analysis
based on energy recovery assumptions – was carried out for each tested scenario, evaluating the
specific industrial treatment cost for the considered organic fraction.

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.
