Sapporo Breweries Ltd., Shimadzu Corp. and Hiroshima University have jointly developed the world‘‘s first technology that can efficiently generate hydrogen and methane from bread waste. Japan for Sustainability reports that their research group announced that their small-scale experimental system had run successfully for over 6 months. The National Institute of Agrobiological Sciences, an independent administrative institute in Japan commissioned and sponsored this research.
Desulphurisation of biogas that contains corrosive sulfur has been a major challenge in attempting to use biogas in fuel cells. The new system, however, can separately generate sulphur-free hydrogen and methane by controlling the fermentation process.
The experiment successfully decomposed and dissolved about 80 per cent of bread waste within only a quarter of the conventional processing time. Furthermore, in terms of calorific value calculated on the basis of the amount of gas collected, the newly developed technology produced over 10 per cent more biogas compared to the existing method of producing methane alone through fermentation.
The research group is now working on further development of the system towards practical application, and launched a pilot-scale experiment in mid-October 2004. Application of the technology may extend to other raw materials such as agricultural and forestry wastes, and expectations are high that it can be used in a variety of industrial fields in future

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.
