In the video below from network administrator Stedin, Frans tells us what is actually done about sustainability. For example, the grower has 8,500 solar collectors (of which 80% of the energy yield is fed back to the grid) and they are working on the installation of a new biomass incineration plant. This installation will provide such a large water capacity that also growers and businesses in neighboring Rotterdam can be heated with it. Moreover, relatively little CO2 is emitted. "The plant (kalanchoe) itself consumes more than we emit here, so in that sense it is CO2 neutral," according to Frans.
