# <u>Recycling old blanks</u> – mixing collected polyurethane cuttings (60%) from old surfboards with virgin foam. Recycling method works only with EPS and does not work with PU. However, PU is preferred because it is more flex, more dense, stronger and cheaper. EPS has tendency to be dumped quicker. PU blanks cannot be recycled as easily as EPS because PU blank sucks the resin into it (Woody, 2009).
# <u>Plant based materials</u> – in the past blanks made of sugar. However this is a difficult material. It
rottens very quickly once the board is broken
