Added value
Greenmaker is able to absorb no less than 660 litres of water per cubic metre of product, without the soil becoming saturated. As a consequence, watering costs are significantly reduced. To illustrate the Greenmaker’s spectacular water-absorption capacity, let’s use the example of an average 18-hole golf course with a total surface area of greens of 1 hectare and a top layer of 20 centimetres. If the soil settles by 10%, in total 2,200 cubic metres of top layer will be needed. The addition to that top layer of 20%, 25% or 30% Greenmaker results in the following water-absorption ratios:
| % Greenmaker | m3 Greenmaker | Water absorption | Water absorption / m2 |
|---|---|---|---|
| 20% | 440 | 290,4 m3 | 29,0 litres |
| 25% | 550 | 363,0 m3 | 36,3 litres |
| 30% | 660 | 435,6 m3 | 43,6 litres |
In the summer golf courses generally need an average of four to six litres of water per square metre per day. After use of Greenmaker the soil can retain up to 11 times the daily water need.
There are almost 200 golf courses in the Netherlands, with a combined surface area of greens of 165 hectares. If all those courses were to add 20% Greenmaker to the soil structure of their greens, just under 45,000 cubic metres of water would be retained on a daily basis. That is a huge saving when you realise that an Olympic-size swimming pool holds 12,500 cubic metres of water. Quite simply, the Greenmaker effect is unprecedented.
Other ways of retaining water in the soil, such as in-built reservoirs, demand heavy investment and are less sustainable. And the operating costs are much higher, because more water evaporates and there are additional energy costs, to pump round the water for instance. Other products related to water storage are often chemicals-based. These products degrade in the soil and leave harmful residues in the top layer. Greenmaker on the other hand actually cleanses the soil.
Greenmaker also contributes to reducing CO2. The Royal Netherlands Football Association requires clubs in its top-flight Eredivisie to use under-soil heating. The average cost to clubs is 120,000 euros per year. Greenmaker saves at least 20% on this amount. The reduced energy consumption also results in less harmful emissions. Lastly, Greenmaker is in full compliance with the EU water directive. The EU has targeted a situation in which only natural products are approved for use as soil additives.
“Greenmaker’s sustainable character sets it apart from other products. It is 100% natural. When you use Greenmaker, you need much less water and less fertiliser, and you emit less CO2. Three environmental advantages for us all.”
