ISSeP has been controlling for ten years the gaseous and liquid emissions of main
landfills in Wallonia. The monitoring of landfill surface gas-emissions is usually performed with
portable FID analysers. Such devices offer high sensitiveness but measuring ranges are
sometimes too short for high methane concentration. It is why another portable device, based on
IR-analyzer technology (ECOPROBE), has been tested and compared to FID in several case
studies. Synthetic air/methane gas mixture has been used to verify the exactness of both portable
analysers. In a second time, the linearity of IR-device has been verified in its large measuring
range from high-rated LFGes. Finally, performances of FID and IR technologies have been
compared on on-field sampled surface landfill gas (LFG). The tests show good proportionality
and low detection limit of FID devices, but with low exactness and low upper saturation limit.
The IR device shows good exactness and linearity on a wide measuring range, but his minimum
detection value is higher than FID systems. This gap increases when analysing complex highrated
gas mixture as LFG. Despite this limitation, IR probe produces other simultaneous
measurements such as carbon dioxide and oxygen concentrations. These data are complementary
to methane values and useful for landfill surface emissions monitoring.

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.
