Skateboards Made From Surfboard Production Waste
Shred Skateboards makes skateboards from castor materials leftover from the surfboard manufacturing process, which is about 6 lbs per surfboard according to Shred. They are cruisers and oversized cruisers in design, and they look really nice, but the starting price ($220 fro the smaller cruisers) is a hard sell. Part of that high cost is certainly the labor intensive nature, and the rest might be due to the probably expensive nature of the alternative high-tech trucks by Alpine. At this point you can only buy complete setups.
The web site could do with some more close up pics of the construction of the boards.
