We feel we made a pretty green board with some of the latest materials. The board was just finished and will keep you updated.
I have really enjoyed making alaias and hollow boards out of wood. The wood I use is grown like a crop and has many beneficial attributes, like creating oxygen and returning nutrition to the soil. Standard foam boards are not great for the environment, but that is what most people ride, so if we need to make foam boards, let's do it better. I will be working on this and will keep you updated on the successes and failures.
