Once again we are headed into smoky season in Northern Thailand, India, and China, as farmers harvest their crops and burn the crop waste in open fields. Warm Heart’s Stop the Smoke campaign focuses on removing the source of the smoke before it becomes a problem. Our solution has been to provide farmers with a way to benefit from their crop waste by turning it into a profitable product, biochar. The process of turning crop waste into biochar is smoke-free and produces a product that has a multitude of beneficial uses. Corn is one of the biggest waste producers of all crops, only 20% of the plant is used, the rest is waste. The burning of this waste is a major source of air pollution that blankets Northern Thailand every year. Our outreach program to help Stop the Smoke has focused on working with farmers in Mae Chaem. The farmers we have worked with in the past will continue this year to convert their crop waste into biochar. They have reaped the benefits of adding biochar to their fields to improve soil conditions and increase crop yields. Our goal this year is to continue to reach out to more farmers to increase the amount of crop waste that is turned into biochar, helping to eliminate more smoke from being generated through open field burning.
