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.
Bronnie Allen, WRAP’s Material Development Manager (Glass), comments, “We have received very positive feedback on the performance of processed sand but a number of greenkeepers have been put off by the slight green colour. It is, therefore, excellent news that the trials have confirmed that by using a blend you can still get the performance advantages of using this recycled product but a colour that is closer to the traditional look.
“There is evidence that more greenkeepers are beginning to specify processed sand and a number of major turf suppliers are now stocking it in response to this increased demand. This research further confirms the great potential processed sand has for the golfing industry,” she adds.
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.
