Kyushu University, Carbon Xtract Corporation (“Carbon Xtract”), National Federation of Agricultural Cooperative Associations (“ZEN-NOH”), Sojitz Corporation (“Sojitz”), and MUFG Bank, Ltd. (“MUFG Bank”) have concluded a partnership agreement as of March 13, 2024, for early practical implementation of separation membrane-based DAC devices (m-DAC)*¹ that enable direct capture of carbon dioxide (CO2) from the atmosphere and can be installed within horticultural greenhouses*² in Japan.

Japan’s agricultural industry faces a labor shortage and an aging population, and the country’s crop yields are trending in decline. Urgent measures are needed to maintain agricultural infrastructure for domestic production. At the same time, global warming is also greatly impacting agriculture. Under these circumstances, it is critical that farmers take proactive steps to reduce environmental burdens through sustainable agricultural initiatives.

Carbon Xtract and Kyushu University conducted R&D for the small-scale m-DACdevices which will be introduced in horticultural greenhouses, and these m-DACdevices are highly anticipated to provide solutions to the issues facing the agriculture industry.

Increasing the CO2 concentration in greenhouses (CO2 application) promotes photosynthesis of plants. Therefore, supplying higher CO2 concentrations is effective in increasing crop yield. The m-DAC devices capture CO2 directly from the atmosphere and supplies a concentrated CO2 stream in horticultural greenhouses, contributing to improve crop yields and decarbonize agriculture.

Carbon Xtract and Kyushu University have therefore partnered with ZEN-NOH, which possesses extensive farming expertise and a network of agricultural cooperatives, to realize a new sustainable agricultural model in horticultural greenhouses. Sojitz and MUFJ Bank have joined these three institutions as partners in this partnership agreement in order to accelerate decarbonization within the farming industry.

[Sustainable Initiatives]
ZEN-NOH’s research facilities will be used to conduct planned future development and demonstration trials of CO2 dosing machines that utilize the optimized m-DACfor installation within greenhouses. Additionally, Sojitz and MUFJ Bank’s company networks, financing function, and business-building function will be leveraged for early practical implementation of the m-DACdevices. All five institutions aim to create carbon credits through installation of these m-DACdevices.

Kyushu University, Carbon Xtract, ZEN-NOH, Sojitz Corporation, and MUFG Bank strive to expand use of m-DACdevices to greenhouses across Japan in order to contribute to both decarbonization of agriculture and to maintain and raise domestic agricultural production infrastructure.

*1 m-DAC®: A direct air capture (DAC) technology based on nanomembrane separation that captures CO2 directly from the atmosphere. Kyushu University is advancing the development of m-DAC® technology, which captures CO2 by simply passing air through membranes having the world’s highest CO2 permeability.
*2 Horticulture greenhouses: Greenhouses used for growing crops that are made using glass or plastic film coverings to increase light permeability.
