Recycling Wastewater for Valuable Soil Nutrient.

Scientists have developed a method to recycle phosphorus from wastewater and infuse it into biochar, a soil superfood made from incinerated organic material. Biochar acts like an underground rainwater sponge that delivers necessary phosphorus and other nutrients for plant growth. The process not only recycles phosphorus and produces cleaner water but also increases soil health and creates a carbon sink that reduces atmospheric greenhouse gases. The method has been patented and could be used to tackle several major problems related to agriculture and pollution.
