Dark Green on the left side field after CleanRise Application, light green on the right side field without application. Darker green signified better nutrition status of the rice plants.
CleanRise has been applied on the left field. Instead of being released into the air, Methane feeds the rice plants.

Climate Mitigation through CleanRise application

CleanRise™ is a methane-derived microbial biostimulant containing beneficial wild-type methanotrophic microbes. Designed through String Bio’s proprietary process, it supports sustainable rice farming, enhances yield and grain quality, and reduces environmental impact.

 CleanRise™ boost yields in the field and in milling, improve nutritional grain quality and cuts emissions.

The product’s microbes stimulate root growth, phytohormone production, nutrient solubilization, and uptake. This leads to stronger plants, higher nutrient-use efficiency, and better quality grains — even with reduced fertilizer.

The results of CleanRise Application and its value propositions

  • Promotes phytohormone production & root growth and improves nutrient use efficiency (good for the plants as they grow stronger and more stress tolerant)
  • an about 50% reduction in methane and nitrous oxide emissions (good for the country and its greenhouse gas footprint, good for exporters selling rice with reduced GHG footprint)
  •  yield gains of 15-39%, proven all over India in over 5 years and in 10 different agricultural regions and over many rice varieties (good for the farmers as productivity gains outstrip the cost of CleanRise and its application considerably)
  •  considerable milling yield increases as the stronger and healthier grain result in less broken rice (good for the profitability of the rice millers)
  • increased nutritional value of the rice with increases in iron and zinc content (good for the consumers)
On the left rice plant panicle from a field treated with CleanRise show much larger and heavier panicles, on the rice control without CleanRise application, all other conditions are identical
Panicles at the left are from a field that was treated with Clean Rise, the right panicles are from identical field without the CleanRise treatment.
two heaps of paddy, both harvested from identical plot sizes. The left, much larger heap is from a plot treated with CleanRise, the right smaller heap from the control without CleanRise application.

The potential of CleanRise application in Thailand

CleanRise can be easily applied to all forms of rice growing. The environmental footprint of all rice can be very much reduced with CleanRise. if applied to all 11 Mio ha, Thailand would produce an additonal 15-25% of rice without more fertilizer usage and reduce the environmental footprint from GHGs from rice by about half.

A reduction potential of 3-4% of all GHGs in Thailand is a lot if we consider that at the moment the total yearly reduction from all sources and sectors are only about 0.7%. With strong civil and governmental engagement this can be achieved in a few years only while improving the competitiveness and attractiveness internationally very much.

When can Thai farmers start to use CleanRise?

Naturally Thailand protects its rich agricultural heritage against uncontrolled imports of pest, unwanted plants, animals and agricultural microorganisms. Importing CleanRise is controlled by the Plant Quarantine Act and related government acts. As the exclusive partner for Sting Bio in Thailand, we are now working through the review and permission-to-import process.
