The ancient civilizations of the Amazon used biochar for their waste streams and, today, their soils retain fertility.  Thousands of years later this process has been re-discovered by, primarily, Cornell University.  Today, biochar is elemental carbon refined from biomass and made cleanly using today's technology. When done responsibly and sustainably, production and use of biochar has been shown to boost crop yields, build long lasting soil fertility, and conserve water. The fact that it can also sequester carbon for hundreds or even thousands of years holds great promise as a viable, scalable mitigation strategy for addressing climate change.
