Corncobs are an ideal feedstock for biorefineries
Corncobs have the highest energy density of all the agricultural residues. However, since the arrival of the cobine harvesters, the cobs are left on the field. Below you’ll see some references on how they can be harvested on the go. Also, in many parts of the world and for maize seed production, the whole ear is harvested and the cobs are then available at the side of the field, at a maize mill or the seed company.
There are many technical and agricultural reasons why cobs are a good biorefinery feedstock choice. We have previously (see: dalinyebo.com/corn-maize) reported:
Removal of cobs does not affect the soil health.
Modern, on-the-go single-pass harvesting systems allow large-scale collection of cobs.
Co-harvesting of corncobs makes sense e.g. for small scale farmers (in Africa and elsewhere).
