used in horticulture as an organic fertilizer for loosening and improving the soil;
sunflower husks are of great benefit when growing mushrooms;
decorative heat and sound insulation boards are made from it;
used for biogas production.
In addition, the husk has a high energy potential; during the combustion process, it releases a lot of energy and heat. Thanks to these characteristics, husk has become in demand in the alternative energy market. Solid biofuel is produced from sunflower husk, which is characterized by ease of storage and transportation, as well as environmental friendliness. The fact is that when burning sunflower husks, no more carbon dioxide is emitted than during natural decomposition of wood, and a negligible amount of harmful emissions is formed. The ash left after burning is quite suitable for plant fertilization.
