Seraplant offers recycled phosphorus-based fertilizers to promote sustainable agriculture. The startup’s process involves mixing sewage sludge ash to make it reactive to chemical bonding, before spraying, granulating, and fractionating the waste. Moreover, the process does not produce dangerous intermediate products and toxic exhaust gases. The fertilizer also contains significantly lower proportions of uranium and cadmium, making it ideal for agriculture.
