Web-Resol Tudo sobre Limpeza Urbana e Resíduos Sólidos!
A fração orgânica putrescível dos resíduos sólidos urbanos pode ser aproveitada através do processo de tratamento
anaeróbio de resíduos sólidos orgânicos realizados com substrato contendo em média cerca de 5% (percentagem em
peso) de sólidos totais. A matéria orgânica vai gerar como produtos o biogás contendo em sua composição um
considerável percentual de gás metano e material bioestabilizado que pode ser utilizado como agente condicionador
de solos. O presente trabalho objetiva avaliar os parâmetros operacionais pH, AGV e AT no processo de
bioestabilização anaeróbia de resíduos sólidos orgânicos. O reator anaeróbio tinha capacidade unitária de 2200
litros, sendo 1850 litros destinados ao substrato afluente e o restante ao biogás produzido. O reator foi alimentado
diariamente com resíduos sólidos orgânicos frescos e com tempo de detenção de 90 dias. Após atingir o estado de
equilíbrio dinâmico, o biogás apresentava cerca de 60% de gás metano e a relação AGV/AT decresceu
gradativamente ao longo do período de monitoração

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.
