Research and Development Targets

1. Enhance technology platform to accelerate development of useful microorganisms
  • By 2030, develop technologies for reducing time required to complete DBTL cycle.
  • In addition, develop technologies to reduce the number of cycles and their cost, and develop technologies for shortening the period for microorganism development to roughly one-tenth its present level.
2. Develop enhanced microorganisms that can produce materials using CO2 as a raw material.
  • By 2030, develop commercial strains of microorganisms capable of realizing levels of material production and CO2 fixation approximately 5 times higher than those realized by common natural strains and enable commercial levels of production for such materials.
  • Alternatively, develop commercial strains of microorganisms that can use different raw or target materials while maintaining production capabilities through the use of genetic engineering on microorganisms that already exhibit high levels of capability for material production and CO2 fixation.
3. Develop and demonstrate manufacturing technologies using microorganisms capable of producing materials that use CO2 as a raw material.
  • By 2030, develop technology for producing microorganisms that reduce the cost of manufacturing materials using CO2 as a raw material to a cost level no higher than 1.2 times that of alternative candidate products (as of 2030).

Assumptions regarding estimates of CO2 reduction effect

  • Estimates of CO2 reductions are calculated on the assumption that products leveraging project outcomes in areas within easy reach of biomanufacturing technology that utilizes CO2 as a raw material will account for 20% in 2040, and 50% in 2050, of markets for raw materials and textiles (e.g., chemical and animal textiles), fuels, foods, and animal feed. Please see the R&D and Social Implementation Plan referenced below for information related to estimated consumption and production quantities for each market, the CO2 reduction factors due to process conversion, and calculation formulas.

Assumptions regarding estimates of economic effect

  • Economic impacts have been calculated using the same product substitution rate as that used for calculating the impact of CO2 reductions, and on the basis of the following product unit prices per sector.
    Formula: Economic impact = estimated consumption per sector x product substitution rate x product unit price
