The benefit of the Big
Dutchman innovation is that, except for nitrogen, all the components important
for fertilization are preserved in the residual ash, resulting in a dual use
independently of wind and sunshine.
Within the Big Dutchman
system, the manure is dried, pressed into pellets and conveyed to a gasifier
where it is converted into gas by means of a thermochemical conversion. The
only by-product that remains is ash – a very valuable fertilizer. The energy
produced is processed in the combined heat and power plant (CHP) to generate
electricity and heat.
In addition to chicken
manure, other by-products such as digestate from biogas plants or sugar cane
can also be used for the same purpose.
The amount of energy
produced in a 150 kW gasifier can supply thermal energy for 25 households for
more than one year (maximum 10 kW heat output) and provide 200 households with
electricity for a year (at an annual average use of 0.75 kW per household).
