Muscat: Two students of Aisha bint Talha School in Bahla, Al Dakhliyah, have developed biochar from expired milk that can be used as fertiliser as well as reduce food waste.
Ruaa bint Rashid al Hinai and Fajr bint Abdullah al Hinai undertook the research spanning several months to create the innovative product. Their process involves collecting expired milk, processing it and transforming it into a biochar-based fertiliser — a nutrient-rich soil application.
Fajr described their product as an innovative approach to repurposing food products – utilising expired milk to produce biochar with significant agricultural benefits. “This biochar serves as a natural fertiliser, promoting crop growth and improving crop quality while minimising reliance on chemical fertilisers.”
The biochar derived from expired milk contains organic components that enhance soil structure, stimulate root growth and facilitate the absorption of essential nutrients by plants. “By reducing the need for chemical fertilisers, it also helps mitigate environmental damage and potential health risks associated with their usage,” Fajr said.
“Furthermore, the efficacy of our innovation has been demonstrated through its positive impact on plant growth, including increased chlorophyll levels, leaf count and crop yield.”
It should be noted that this biochar extracted from expired milk contains organic materials that contribute to improving the soil structure, stimulates root growth, and enhances the absorption of essential nutrients for plants. In addition, it reduces the use of chemical fertilizers that may be harmful to the environment and negatively affect public health.
She added that the biochar product has proven effective in plant growth and increasing the percentage of chlorophyll in it. It also increases the number of leaves and the amount of the crop.
