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

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
