Anantara Bazaruto Island Resort
in Mozambique have installed Earth Probiotic’s Earth Cycler food waste composter and biochar Earth Kiln retort. All food waste will be composted and fed back to soil. The biochar retort will process palm tree waste into biochar. The palm tree waste is currently a fire hazard and, due to its fibrous nature, extremely difficult to compost directly.
Making biochar in a retort system is a carbon negative process. Volatile gases re-burn to heat the retort. Biochar is a means of capturing and storing carbon in the soil (where it can lasts for decades if not centuries). In soil, biochar acts as a sponge to hold nutrients, microbes and water.
