Justlife™ Earth Day Carnival 2009 team wanted an educational event that is fun and inspiring; with ideas that everyone from all walks of life can adopt and practise in their daily life. Inspired by Y’shin (a young architect that recently embarked on eco-building design) who came out with the first version of layout plan and the book “Cradle to Cradle” (co-authored by architect William McDonough and chemist Michael Braungart), we concluded the EDC 2009 theme -“Reuse”. Hence, the birth of this Reuse Guide.
