Abstract
An improved process for enhancing the plant nutrient value of reltatively low analysis waste material (e.g. sewage sludge) involves treating the waste material with an acid and base in a pipe-cross reactor (12). The process more particularly involves mixing the waste material with water to form a slurry (or initially taking the waste material as a slurry); pumping the slurry to a pipe-cross reactor for reaction with a base (30), acid (26, 28) and water to form a melt; spraying the melt onto a recycling bed of fines in a granulator, and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles to form an enhanced plant nutrient value composition (e.g. a fertilizer or soil conditioner having a greater 'NPK' value than the original relatively low analysis organic waste material).
