Plastic pollution is a major problem on island territories which often lack infrastructure for processing recyclable materials. They are either buried or incinerated while a circular economy is possible.

Citizens who use the Sunbox or the Solarcube are rewarded for their ecological gesture with a voucher proportional to the number of plastic bottles or cans introduced into our RVM (Reverse Vending Machine). 

The Sunbox is a compaction box with 1 to 4 rvm that compact plastic bottles, glass bottles or cans. The storage capacity depends on the volume of the compaction chamber which is beetween 11 to 20 m3. This corresponds, for example, to 75,000 plastic bottles (11m3) to 130,000 plastic bottles (20m3).

The Solarcube is less efficient than the Sunbox because its storage capacity is 6,000 bottles.
