The biochar process is ingenious, turning green waste into heat before returning it to the soil as an agricultural nutrient. No wonder it’s turning a profit.
Maintaining soil organic matter is critical to tackling climate change because soil organic matter is rich in carbon. Soil carbon is also the keystone element controlling soil health, which enables soils to be resilient as droughts and intense rainfall events increasingly occur.
Soil specialist says a burned organic material, biochar, improves growing conditions.
A team of researchers from the National University of Singapore (NUS) has developed a novel new method to recycle wood waste [as biochar] by incorporating it into cement and mortar mixtures, making the resulting materials both stronger and more watertight.
