The Groasis waterboxx raw material

The waterboxx buyer is able to buy the box in two different kinds of raw materials:

• Polypropylene
• Biopolymer

Polypropylene

The polypropylene box is made of a high quality PP with sufficient additives to survive the harsh conditions of deserts. As the sun is the enemy of plastics the design, construction and material of the waterboxx has been subject of long research and durability tests. The waterboxx made of PP will survive at least 10 years depending on the number of hours of sunshine and the difference between day- and night temperatures. A careful treatment while replacing will certainly lead to a longer period of use.

With the PP box a minimum of 10 trees is expected to be possible to plant over the years. In countries with 2 rain seasons, for instance Kenya, a double number of trees may be expected to plant with it. This makes the cost price of use low. In order to calculate the costs and possible profit use the calculation document.

The polypropylene waterboxx can be used on:

• Poor and degraded soils
• Rocks
• Deserts
• Eroded areas
• Burned woods

Biopolymer

The biopolymer waterboxx can be used for one tree. The biopolymer waterboxx first produces water and once degraded, it produces nutrients for the tree. The biopolymer waterboxx can be used on

• Extremely poor and degraded soils
• On difficult to reach rocks
• On places that are very difficult to reach it means that once being used for planting it is not necessary anymore to take them off
• Deserts and especially on places where sand dunes are developing through strong winds
• The development, maintenance and stimulation of dunes
• Burned woods where all the humus has been burned too
• In situations where the management wants to have simple working methods: just place them and leave them there

Although per planted tree the box is more expensive, its advantages are so promising that the use may be considered in many occasions. In the calculation document it is possible to see where the advantages are:

• faster growth through more nutrients and micro-organisms caused by the degradation process after the start
• higher success rate of planting
• less labor and management costs
• it is possible to use land with hardly any value

General

In moderate areas the box will stimulate growth with approximately 15%. So although the box is an extra investment in these climates, the extra biomass production or other products makes it interesting to use it.
