Typically, recycling scrap aluminium requires only 5% of the energy needed to produce the same amount of metal from bauxite ore. Clearly, this makes the process very attractive, both in financial and environmental terms. If, however, high levels of throughput, combined with efficient recovery, are to be achieved, sophisticated recycling furnaces are needed.
e4engineering.com reports that to this end, recycling expert Platinum Controls has developed a new range of ultra-efficient recycling furnaces that feature innovative control systems. Platinum specialises in the development of these furnaces, and the results achieved by its latest models are such that, in many applications, they have a payback period of just six months.
These furnaces comprise a refractory-lined cylindrical drum, which rotates and tilts while applying heat from gas/air burners to the scrap material. At the end of the melting period, the rotation ceases, and the drum is tilted to allow the molten aluminium to be poured off.
The process sounds simple, but achieving consistently good performance depends on precise control over variables such as temperature, rotational speed, tilt angle and melt time. Platinum has used equipment and technology from Omron Electronics to implement this precise control for the new furnace.
Omron’s fuzzy logic system allows the process to be optimised on the basis of simple rules that can be refined over time. This approach, which does not depend upon the development of accurate mathematical models, is proving very successful in making the recovery rate less dependent upon the skill of the furnace operator. Efficiency gains of around ten per cent are already being achieved, and even higher gains are expected as the fuzzy logic is fine-tuned.

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.
