Corn Cob Biochar is Rak Din's standard biochar feedstock. We buy our corn cob biochar from small farmers in North Thailand who would otherwise burn it, contributing to the annual haze crisis. By preventing corn cob from being burned, Rak Din sequesters CO2 and averts the emission of eCO2, smog precursors, PM2.5 (haze) and black carbon. Every day farmers make biochar, they also earn a fair day's wages during the dry season when there is no other work available. Rak Din is proud of how its biochar purchases contribute to poor communities across the North.
Longan Biochar is Rak Din's "hometown" biochar. We are located in Phrao District, Thailand's longan capital. When the crop is in and everyone has had a rest, we begin pruning our longan trees. Just one rai of trees (25 trees, generates 1.25 tons of branches. Multiply that times several hundred thousand rai and you have a lot of wood! Before Rak Din, pruners just burned the branches, sending clouds of smoke into the sky. Today, they load the branches into trucks and haul them to Rak Din where we buy them. We are happy - longan wood makes great biochar - and the pruners are happy because they make extra money every day!
Bamboo Biochar has a storied history. In Japan, bamboo biochar has been used for centuries as a natural deodorant in houses and as a natural decontaminant in drinking water. Even today, you often see a beautiful black section of bamboo biochar standing in a water jug in a Japanese kitchen. Our bamboo biochar shares the same purity as traditional Japanese bamboo biochar. (If you are interested in purchasing whole sections of bamboo biochar rather than our standard crushed char, please special order it. We can normally deliver within a month anywhere in Thailand.)
