Thank you for your interest in WGDN. Over the last three years the WGDN grew rapidly with active membership of Dutch, Belgium, English and Scandinavian companies and its suppliers. To become a truly international initiative, it was decided to join forces with the UK based TFT Quarry working group which also runs a similar program in range of production countries.
