We have built three new shelters in two days out of tire bales!
Each tire bale weighs 2,000 pounds, meaning that it not only provides excellent heat absorption during the daytime (keeping animals warm at night), but also that it recycles that much waste. We are building multispecies shelters so that our animals may be better housed together, and besides 30 tire bales per shelter, scrapwood, recycled tarps and other recycled materials are put to use reducing our costs of production (making food, fiber and other anima products cheaper for people). More than 70,000 pounds of waste are recycled in every pen.
The tire bales are engineered to withstand more than 60,000 pounds of force in any direction, making them the new, hottest material in civil engineering! The tire bales require a bobcat to move, which is very hard on the soil of the animal pens. Luckily, we rotate pens, reclaiming them between uses, so that our animals always have good turf to walk on.
Though recycling is big money, agriculture is always on the forefront of the industry, developing low-tech methods of recycling. However, low-tech often inspires high-tech, and we understand that tire bales are going out of style as higher uses for the old tires are found: a new machine just invented will allow recyclers to earn nearly $10 per tire by converting the tire into diesel fuel (about 1.5 gallons per tire), scrap steel (more than a pound per tire) and also carbon black. That's about 23 times more value per tire than baling them!
And baling the tires is about 4.5 times more value than loose tires (which we also use on our farm). Technology improves, and suddenly, the recycled material which farmers could get for free is rendered into products envied by civil engineers and becomes beyond their ability to buy. Luckily, there's more kinds of rubbish than tires, and the farmer will find new materials to use: there's always new forms of junk.
