    "goal": "Convert dead trees and other vegetative waste into a nutrient-rich, natural fertilizer.",
    "problem_addressed": "Large quantities of forest slash and dead wood that are normally burned or landfilled, creating fire hazards and environmental waste.",
    "concept_summary": "Roy's patented process loads chopped vegetative material into a horizontally oriented plastic cylinder that contains at least one free-moving metal rod. The cylinder is rotated, producing uniformly sized, dry particles that absorb any sap or liquids present. The resulting particles are sold as a natural fertilizer called Mill Creek Soil Primer.",
