New research results demonstrate that using a blend of processed sand (made from 100% recycled glass) and conventional sand offers performance and environmental benefits and is closer to the traditional sand colour. This is especially good news for greenkeepers who are reluctant to use processed sand due to its natural green colour
To find the optimum colour and performance ratio, trials were undertaken by the Sports Turf Research Institute (STRI), on behalf of WRAP (the Waste & Resources Action Programme). The trials compared different blends of conventional and processed sand and showed that the optimum ratio was a 50:50 blend. This ratio maintained processed sand‘‘s performance advantages such as firmer underfoot conditions and reduced plugging of the ball, but also significantly reduced the green colouring.
This was the second trial carried out by the STRI. Earlier trials demonstrated that processed sand was ideal for use in a range of applications on the golf course, including bunker sand, divot repairs, and as top dressing.
WRAP intends to take the results from all the research carried out with the STRI and apply it in situ, working with several high profile clubs. One of these will expand their course constructing new greens, tees and bunkers using processed sand. Once mature, players will be able to experience play for the first time on a golf course constructed using processed sand

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.
