Education EN ↓ 30 episodes

Char Chit Chat is created by Dylan Graves and explores char in New Zealand and beyond. The podcast aims to interview a range of people involved in biochar, activated charcoal, carbon anodes, and so on. The main subject will tend to be biochar as that is most accessible and scales from individuals making char in their woodstove over the winter to large industrial pyrolysis units outputting several tonnes per day. Biochar is also a great soil conditioner and improver and so is relevant to gardeners and farmers alike. An introduction and overview of Biochar: https://www.sces.org.nz/biochar

Episode 8 with John explores his recent discovery of biochar for his compost and his method of making it in a stainless steel bucket.

CCC S1E13 with John McDonald-Wharry 30.08.2025

John is a researcher and academic so it was great to hear his perspective and explanations of biochar knowledge that he has gained from doing a PhD tackling 3 aspects of biochar; investigating how biochar changes on a molecular level at different carbonisation temperatures, quality testing protocol development, and composite materials innovation. Ket takeaways for me : 1. Higher temperature pyroly...

CCC S1E12 with Simon Day 29.07.2025

Episode 12 was an inspiring chat with Simon from Waiuku (40km south west of Auckland city) who uses biochar to enhance his pastures as well as feeds it to cattle to improve their health. The success is evident in the increased pasture regrowth times and animals not needing drenching, having high fertility rates, and growing faster. Yes, it is work to make biochar, but the benefits are obvious to S...
