Project for Soil Purification Technology and Environmental Remediation Aided by Plants

An issue in re-using the site of an old factory is the environmental impact associated with soil contamination and the cost burden of any remedial measures. For example, under the revised Fire Service Act of Japan, gasoline stations are now obliged to repair any underground tanks that have lain under the ground for more than 40 years, and as a consequence of this, it is expected that between 1,000 and 2,000 stations will close down each year.

In order to meet the demand for environmental remediation and measures dealing with soil contamination, the Sumitomo Forestry Group has been working on cleansing contaminated soil by using the functions of plants (phytoremediation). As part of this, during fiscal 2012, in collaboration with JXTG Nippon Oil & Energy (JX Nippon Oil & Energy Corporation at the time), the Group developed a method for purifying soil contaminated with oil using Burning Field, a variety of Japanese lawn-grass independently registered by the Group.

One of the functions possessed by the variety of Japanese lawn-grass used in this method is that the nutrients transpiring from its roots activate microorganisms in the soil, and the upshot of this is that it has the potential to inexpensively reduce the oil content in polluted soil. This method has been adopted at nine sites so far to purify areas where gasoline stands or oil depots once stood, with purification at three sites now complete.

In fiscal 2013 and 2014, the Ministry of the Environment conducted a study on low-cost, low-impact technologies for surveying and for counteracting contaminated soil in addition to presenting the Environmental Measures Exemplary Efforts Awards (Minister of the Environment Award) in 2013. The study found that oil-degrading microorganisms tend to become more active, and were recognized as having potential to be applied at sites heavily contaminated with oil. Received the Good Design Award in October 2018 from the Japan Institute of Design Promotion.

Moving forward, by steadily producing results in soil purification based on this technique, the Group will continue to help resolve the nationwide problem of oil contamination.
