In 2000 a team of artists working for the Freeform Arts Trust decided to find ways to use recycled materials in public arts projects as a contribution to sustainability in the built environment. After much consideration glass was chosen because of the amount that needs to be recycled, its ubiquity, its intrinsic qualities physical properties and not least its beauty. The challenge was to make a beautiful product from waste, which is good enough to attract sales in its own right and meet the standards for fit for purpose applications.

The Green Bottle Unit was formed within the Free Form Arts Trust led by Martin Goodrich - Artistic Director and developed from original processes and designs for recycled glass by David Watson.

Now known simply as GBU a great deal of technical research and development has been completed and a range of standard products has been perfected called eluna . During this extensive research and development programme a number of one-off designs were created and produced for a variety of prestigious projects and these can be seen at:

• Broad Street - Reading Borough Council
• Kamukura House – Japan - Fosters & Partners
• Shoreditch Arts Trail - Shoreditch Trust and Hackney Borough Council
• Islington Canal Markers - Islington Borough Council
• S.H.A.D.A on the Waterfront - Stepney Housing Association
• Joan Edlis, Lighting Feature – private client
• Landscaping private development - Colchester - Barratts South Eastern

Now established as a Limited Liability Partnership and financed by The Adventure Capital Fund and Free Form Arts Trust. GBU LLP is a social enterprise that aims to meet the demands of architects, interior designers and landscapers seeking high quality versatile building products that also contribute to environmentally sustainable objectives and targets.
