Recycled carbon fiber (RCF) comes from the huge waste streams generated in wind turbine and aircraft manufacturing.   Compared to poly line, RCF cable can (1) provide greater yield per acre through increased planting density,  (2) stay in the water and with a far longer useful life and enhanced. suitability for multiple crops more efficiently and effectively over the course of the year and (3) incorporate cleaning and harvesting devices to reduce labor cost and increase efficiency in farm operations in ways that poly line does not allow.
