Effects of pyrolysis temperature on the physicochemical properties of empty fruit bunch and rice husk biochars

Biochar has received great attention recently due to its potential to improve soil fertility and immobilize contaminants as well as serving as a way of carbon sequestration and therefore a possible carbon sink. In this work, a series of biochars were produced from empty fruit bunch (EFB) and rice hu...
