If they used it for feed stock there would be lots of beautiful pork and beef to consume instead of wasted energy and ruined engines.
Just saying. I wish I could grow sugar cane just to run through a chipper to make mulch for my garden. Corn and sunflower stalks are thankfully an adequate substitute.
I grew sugarcane in my backyard garden a few years ago and tried to use it as a privacy fence. But when they got tall, bushy and ripe all the neighborhood brats came around and tore them up. Just for the sweet goody of it. I ripped out the tattered remnants and mulched them. And wouldn’t you know it? The sugarcane mulch attracted fire ants. Sugarcane is easy to grow in a temperate climate, but it ain’t worth the hassle.
