NR Instant Produce Public Company Limited, or NRF, a leader in the global sustainable food industry, is supporting a prototype biochar production project, using a high-efficiency kiln for agricultural waste. This initiative, in collaboration with the Energy Research and Development Institute-Nakornping at Chiang Mai University, aims to convert agricultural waste like corn cobs, stalks, roots, leaves, and husks into biochar. This biochar helps reduce burning and greenhouse gas emissions (Carbon Negative), contributing to a low-carbon economy.

The project addresses smog caused by burning agricultural waste in northern Thailand, which has long affected the quality of life in Chiang Mai, Chiang Rai, Lamphun, Lampang, and nearby provinces. Burning corn for animal feed and other crops releases carbon dioxide (CO2) and other toxic gases, leading to high levels of PM2.5, impacting public health and the local economy.

In response, NRF has supported the Energy Research and Development Institute-Nakornping in developing a prototype biochar kiln capable of processing up to 50 kilograms of agricultural waste per day. The kiln uses energy-efficient combustion methods, such as firewood, used vegetable oil, and compressed charcoal, maintaining a controlled burning temperature of up to 700°C. It also includes a material drying unit to enhance biochar production efficiency.

The expected outcomes of this project include significant reductions in greenhouse gas emissions and added value for the circular economy. The biochar can substitute chemical fertilizers, store carbon in the soil and increase fertility, while reducing agricultural production costs. This technology can be expanded to communities and smallholders, promoting long-term sustainability.

NRF's support not only aims to reduce burning and smog but also promotes the optimal use of resources. This aligns with the Bio-Circular-Green (BCG) economy concept, which emphasizes the efficient use of materials while minimizing environmental impact. NRF hopes this project will be the starting point for innovations that contribute to a low-carbon economy, which can be expanded to other regions and serve as a model for international development.

NRF believes that developing innovative environmental solutions will not only help reduce greenhouse gas emissions but also enhance Thailand’s global competitiveness, especially in an era when major trading partners like the European Union (EU) have implemented stricter environmental measures. Producing environmentally friendly products is crucial for maintaining competitiveness and ensuring Thailand’s economic sustainability.
