While the move gives a viable outlet for the 149 tonnes collected each month, it also provides an alternative to road haulage, thus reducing congestion and pollution on Cornwalls roads.
The quay at Newham is also only half a mile from the local authoritys bulking up facility, meaning that after the glass is collected from the doorsteps of 42,000 households, it travels as small a distance as possible.
This is the result of a link-up between the council, Cory Environmental and Cornwall Cullet who add the waste to their collections from bottle banks and commercial outlets.
CDC principal officer Alan Miller said: CDC is very proud to be associated with this environmentally improved method of transporting residents recycled glass. We hope that this scheme will lead the way for even more commodity types to be transported in this way.
The authority is working in very close partnership with its committed contractors, and with environmental improvements such as this, everyone in Cornwall will benefit from these successful partnerships.
A ship with a 2,000 tonnes capacity is used, with all material loaded on to this for its journey from Newham Quay.
Cornwall Cullet founder John Lee added: This is the best recycling scheme for mixed glass along with green glass from the bottle banks in Cornwall. The use of the ship saves 70 articulated lorry loads on Cornish roads so this is a much greener way to transport the glass.
