It's probably more appropriate for our forestry colleagues, but it's a big problem in agriculture all over.... What do you do with residue off field? We've been working with industry and looking for a whole bunch of different uses—making biopellets, different fuel sources, different ways in which we could leave the residual straw on the field for grazing purposes. In the west, a whole cropping livestock technique around swath grazing has emerged, where rather than clearing the field, you pile it up and let the cattle out on it, and then they can use that as a food source during the winter months.
Yes, it is a big issue. In some cases we're even looking at harvesting it and taking it for further processing, so there may be some value in extracting components from that, which could then be used for different bioproducts as substitutes for petroleum.
