Takino Filters prevent erosion of red clay during greening.
|In Okinawa Prefecture, Japan, the persistent problem of red clay sediment runoff creating ocean pollution induced an ordinance to be enacted in November 1995 mandating that seawards effluence msut be contained to only 200 parts per million.
In March 2008, inside Camp Hansen Marine Corps Base, located in the outskirts of Ginozason, a 270 meter slope used for helicopter operations had become barren due to continued effluence of the soil, making restoration of the area an urgent issue.
Due to its proven results in multiple situations, Takino Filter technology was adopted to return the slope to its natural state.
|Due to its proven results in multiple situations, Takino Filter technology was adopted to return the 270 meter slope to its natural environmental state.
After scattering seedlings on the summit of the 270 meter helipad slope, SP-45 Takino Filter mats were used to cover the target area.
Effect and Outcome
|After installation of the Takino Filter growing mats, just two days later massive rainfall of 54mm occurred. Based on photographic evidence, a ditch at the foot of the slope showed no accumulation of effluence.
This installation has become a representative example of the efficacy of Takino Filters, with their ability to prevent soil runoff despite being subjected to the intense rainfalls peculiar to Okinawa.
