Not only can it prevent surface erosion, but it can also promote the enhancement of natural vegetation.
"BSC-1" is a surface erosion control material that prevents soil surface erosion and promotes the natural invasion of vegetation. BSC stands for Biological Soil Crust, which refers to the natural phenomenon where algae, fungi, and moss cover the soil surface in a sheet-like manner. "BSC-1" primarily consists of dormant soil algae in a dry state, and when spread on the soil surface, it forms a BSC that prevents erosion caused by rainfall and other factors, thereby preventing the loss of buried seeds and promoting the establishment of airborne seeds. "BSC-1" uses cosmopolitan soil algae that are native species found worldwide, ensuring no impact on the original vegetation. Additionally, these soil algae are asexual and reproduce by division, so there is no formation of hybrids or genetic disruption. *There are also construction records in areas with strict environmental conservation regulations, such as national parks.

basic information
The construction method involves simply changing the seeds used in conventional seed spraying work to "BSC-1." (These are mixed with fertilizers, fibers, adhesives, etc., and sprayed.) In narrow areas where a hydroseeder cannot be used, it is also possible to apply using a submersible pump or by hand. Recently, construction using helicopter application has also been conducted. 【Features】 - Materials for natural invasion promotion methods and soil surface erosion prevention methods. - Can be used in conjunction with other methods such as seed spraying, or for repairing existing greening works. - Applicable even in places where slope shaping is not possible. - Since it is just sprayed, it contributes to reducing processes and shortening construction periods. - Forms BSC in areas where water flows, preventing the expansion of erosion. - Can also be applied using submersible pumps or by hand. - There is no impact on the diversity of native species, such as hybrid formation or genetic disruption. 【Related Methods】 ■ BSC Method (Patent No. 3718203, Patent No. 6734500) *For more details, please download the PDF or feel free to contact us.

Company information
We have been aiming to become a specialized manufacturer of microalgae for over 40 years, continuing research and product development in partnership with various universities and research institutions both in Japan and abroad. In recent years, large-scale natural disasters occurring globally, soil and ocean pollution due to development, and the relentless progression of global warming have made environmental destruction increasingly severe on a global scale. Through our collaboration with Japan Engineering Co., Ltd., we have focused our research on the theme of "preventing sediment runoff using microalgae," and finally in 2018, we co-developed the "BSC (Biological Soil Crust) Method." The "BSC Method" is a groundbreaking technique that utilizes soil algae to prevent soil erosion and promote natural infiltration, making it the first of its kind in the world. It has been recognized as an environmentally friendly material that can be used even in national parks, and it has been registered in the Ministry of Land, Infrastructure, Transport and Tourism's new technology development system, accumulating construction achievements in various locations. In today's world, where sediment disasters occur frequently, we are confident that the "BSC Method" can contribute to disaster prevention and mitigation. We will continue to contribute to "human health" and "the Earth's environment" through microalgae in the future.
