Funded by Wallonia's Recovery Plan, the Circular Hemp Pole project worked with Liège-based company Terval on producing agropellets from hemp shiv, a by-product of textile hemp.
Trials show moisture is decisive (around 12%, 15% at most) and that adding lignin, sawdust or dolomite improves mechanical durability and ash behaviour.
Pelletising costs are estimated at €50-60/t for a reference investment of €650k (2.5 t/h). With a still loosely organised hemp sector, the study concludes that larger volumes and other agricultural by-products would be needed for energy use to be viable.
