An analyze of the compost from our Big Hanna composters installed at Conseil General du val de Marne, France meets the French standard NF U 44-051 for soil improver.

When the compost meets the NF U 44-051 standard it becomes a product and is no longer considered waste. It changes its nature. It can be used for the maintenance or restoration of soil organic matter and the improvement of its physical and/or chemical and/or biological properties.
