“[…] The International Biochar Initiative, on its website, explains that large amounts of agricultural biomass are burned or left to decompose, releasing carbon dioxide and methane into the atmosphere. Using agricultural wastes to make biochar removes them in the pollution cycle.
The carbonized rice hull, according to PhilRice, contains micronutrients such as phosphorous (P), potassium (K), calcium (Ca), magnesium (Mg), that are vital for growing crops. In rice production, farmers can use it as soil conditioner, organic fertilizer, waste water filter, and pest control agent.
Heat generated from the CtRH carbonizer, on the other hand, is used to the cooking attachment for pasteurizing mushroom fruiting bags (MFBs). The mushroom production is an income-generating activity in the integrated rice-based farming system PhilRice calls as Palayamanan.”
