Together with Kobe Steel Ltd., Kobelco Eco-Solutions Co. in Japan has developed a high-efficiency thermal storage and transport system called "ThermoWay". Japan for Sustainability reports that successful middle-distance transport experiments were recently conducted on public roads, and the system has entered the final demonstration phase before moving toward commercial scale implementation, according to an announcement earlier this year.
With this system, waste heat of 200 degrees Celsius or lower from plants and garbage incinerators, which has until now simply dissipated, can be stored in a thermal storage device and transported by truck to faraway destinations to be used as high-temperature water of 90 degrees Celsius or more. Transported waste heat can be used widely as heat source not only for hot pools, melting of snow on roads and agricultural greenhouses, but also for district cooling and heating when combined with absorption chiller units.
Smaller scale tests using a one-ton experimental heat-storage system waste, which used trucks to transport containers 5 kilometers, were successfully conducted in July 2005. More recent tests, conducted in February 2007, used a four-ton heat storage system, which is the minimum practical size for such a system, and transported containers about 35 kilometers on public roads, after which hot water of 90 degrees Celsius was successfully retrieved.
The companies believe that 20-ton heat storage systems can be put into practical use in the second half of fiscal 2007. One such system can store about 1.7 million kilocalories of heat energy (equivalent to 200 liters of oil), corresponding to the calorific value required to heat 40 households for a single day.

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.
