What is E3 BioFuels doing to keep the topsoil productive, now that theres a major new demand for corn?
One of E3 BioFuels’ products is aqueous ammonia fertilizer, which in the closed-loop system is created from manure treated in the anaerobic digesters. After manure is processed at the anaerobic digesters, it is sent to a nutrient recovery unit that extracts aqueous ammonia fertilizer, which can serve as a replacement to commonplace natural-gas based fertilizers used to grow corn. This ammonia fertilizer is injected below the surface, so virtually all of it stays in the soil to nourish the corn, instead of two-thirds of its nutrients potentially washing away when manure is applied at the surface. The ammonia fertilizer is also a marketable product, so it’s an additional source of income for the plant—important from a business and investment perspective.
