The Mission: Change from Energy Crops to more sustainable organic Residues
straw (wheat, rice, maize), green waste, bagasse (sugar cane), EFB (palmoil-waste)…
Millions of Tons of such residues are burned, compost or rot without any use
Problem: Residues are rich in energy, but indigestible due to strong structures
