    "But the key thing that excites Jolliffe about biochar is that it avoids waste and it can actually give something back to the environment. "The nice thing is that the biochar doesn't just sit there in a heap," she says. "It's used for soil regeneration. You can spread it on the land and it can not only enhance the soil's capacity to manage moisture, but it also acts as a fertiliser."
