Endocap

Researchers in the United States say agricultural waste from coconut and mango farming could generate significant amounts of off-grid electricity for rural communities in South and South-East Asia. Many food crops have tough, inedible parts that cannot be used to feed livestock or fertilise fields. Examples of this material — known as “endocarp” — include coconut, almond and pistachio shells, and the stones of mangoes, olives, plums, apricots and cherries.
