Yamamoto Neoprene and the Enviroment

Our Neoprene is an environmentally friendly material.

We have been emphasizing with, pride that YAMAMOTO Neoprene is not made from petrochemicals but is from a limestone based polymer with 99.7% calcium carbonate. It is not true that calcium carbonate foam is not as clean and environmentally friendly. We don't use petroleum as the main resource. The quantity of heat for processing and producing our raw materials is merely one tenth of that being used for refining the petroleum based neoprene and the excess heat is used for the nursery of eels. The source of heat is from used tires and the electric power is generated from several dams and power stations constructed downstream of a high mountain range. This special technology to convert the limestone to rubber is really environmentally clean and friendly.
