Utilization of small-scale distributed rice husk heat: "KoCona System" - A guide to a decarbonized and sustainable society built by agricultural innovation.
Rasa Industries has established a technology to crush 'rice husks' into powder form at low cost and in large quantities, as well as an energy utilization technology that burns the crushed material as fuel in a dedicated hot water generation system, providing a heat source for facilities such as hot spring resorts and greenhouses. While it is used as a crushed fuel, by manufacturing it at a lower cost than fossil fuels, it offers benefits to the heat utilization side, increases the calorific value of the rice husks themselves, homogenizes the fuel, and improves storage and transportation efficiency. Additionally, by burning and cooling it instantly like air or liquid fuels, it does not generate crystalline silica (cristobalite). With the expansion of SDGs investments, active movements for climate change measures, and environmental considerations becoming selection criteria for transactions, efforts towards regional decarbonization are becoming a necessary condition. ◆ Struggling with the disposal and use of 'rice husks' ◆ Wanting a heat source to generate hot water for launching decarbonization projects ◆ Considering regional energy circulation within the community, etc. "Heat" ⇒ Supplied through the "Rice Husk Heat Utilization KoCona System" "Electricity" ⇒ Self-generated through solar power, wind power, etc. (excluding biomass) We aim to save Japanese agriculture, support community development in addition to energy demand, and contribute to the establishment of a Japanese version of "Stadtwerke."

basic information
The amount of agricultural waste known as "rice husks" is said to be about 2 million tons per year, generated steadily and being dry, which gives it a high calorific value. In resource-scarce Japan, it becomes an important biomass resource that can replace wood. Currently, its uses include compost, drainage materials, and bedding, but the reality is that most of it is incinerated. If "rice husks" can be used as fuel and safely combusted for thermal utilization, it will enable the construction of a decarbonized society and a sustainable society. Rasa Industries, through its "Rice Husk Thermal Utilization System," aims to connect agriculture with local facilities and industries, going beyond the established frameworks, and contribute to a decarbonized society and the achievement of the SDGs. 【Features】 ◆ Utilizes local materials (regional economic circulation, regional symbiotic zone) ◆ Reduction of CO2 emissions (decarbonized society) ◆ Job creation within the region, inducing the movement of people within the region ◆ Local fuel prices are not influenced by external factors or regional circumstances ◆ Transformation into a resource and fuel-generating region that supplies energy and other resources to outside areas ◆ Potential for tourism demand (eco-tourism)

Detailed information
-
In February 2020, the first introduction in Japan was made with the subsidy from the Ministry of the Environment's "Promotion Project for the Introduction of Independent and Decentralized Energy Systems that Simultaneously Achieve Local Disaster Prevention and Mitigation and Low Carbonization." This system has been installed in a bathing facility in Akita Prefecture and is currently in operation. *Inspections can be arranged at any time, so please feel free to reach out.
