, the international award-winning watering rim

Increasing global warming means that even in our latitudes it is now imperative to water freshly planted trees with a system that reaches all the roots in the root ball.

The two watering edges developed for the most common plant sizes and successful worldwide are made of recycled polypropylene (PP), as described above. Due to their contoured shape, they are dimensionally stable even with thin wall thicknesses of 2 mm. This naturally reduces weight and the amount of plastic used.

The energy balance: the two molded rims weigh 0.72 kg and 1.26 kg. To produce one kg of PP, 2 liters of crude oil are consumed. In the process, 60 % remains bound in the material. It would only be released when it is incinerated.

This means that 6.34 kg ofCO₂ is consumed per kg of PP. The two casting rims therefore correspond to 4.56 kg and 7.99 kg of CO₂

The diameters of the two pouring rims are 50 and 67 cm. The corresponding bale sizes belong to young trees with trunk diameters of 14/16 to 18/20, which have an average dry wood weight without roots of around 50 kg and 90 kg. If they are burned, 1.84 times the amount of CO₂ is produced in each case.

The use of 4.56 and 7.99 kg of CO₂ in the production of the two pouring edges binds 92 and 166 kg of CO₂ respectively. This is an average factor of 20 to 1 in favor of the watering rims.

In addition, the balance in favor of the arboGreenwell™ is significantly improved because they are made of recycled PP and can be reused several times.
