We will miss his beautiful guitar playing, and we’re so happy he came to visit!

Besides cutting CO2 emissions by storing the carbon from organic waste, biochar increases soil fertility, improves plant growth, promotes microbial life, increases water retention, and attracts heavy metals thereby filtering water runoff. Biochar can also be used to augment urban low-impact development such as green roofs, bioswales, and green space to manage stormwater and rebuild degraded soils.
