Next, the green compost gets laid in rows on a concrete surface, where the huge 2-storey pasteurizing machine processes it daily for 12 days. Subjecting the compost to high heat above 55 degrees Celsius not only kills pests, pathogens, weed seeds, and harmful bacteria in the mass but it helps the composting process, which normally generates heat anyway. It just speeds up the process from 3-6 months to 14 days!
