San Diego company makes soy-based blanks

Homeblown Foam Systems of San Diego makes foam surfboard blanks that are 40 to 50 percent soy-based rather than polyurethane.

The eco-friendly materials add about 5 to 10 percent to the total coast of the board, the manufacturers say.

"We're the only company that makes foam this way," said Ned McMahon, whose company was featured Friday on NBC's Channel 7/39 in San Diego.

The company is working toward making a 100-percent bio-friendly board.
