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, improve grain quality and cuts emissions.
The product’s microbes stimulate root growth, promote phytohormone production,
improve macronutrient 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)
- 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 benefits as CleanRise increase head rice recovery and reduce brokens, (good for the rice millers and thier profitability)
- Increased nutritional value of the rice with increases in Iron and Zinc content in the grains (good for the consumers)


The potential of CleanRise application in Thailand
CleanRise can be easily applied to fields with different rice management practices. 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 cultivationby 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.
