Coffee husks (silverskin) are paper thin so pelletizing makes sense. Spend grounds would also be available.
http://repositorium.sdum.uminho.pt/bitstream/1822/22361/1/fulltext.pdf A few years ago a company here supplied two 25 kWe gasifiers for coffee husks (silverskin) to Costa Rica. I saw the husks and the gasifier but never saw it run and wasn't invited back. We understand that the gasifiers in Costa Rica never operated.
