In 2006, DoiTung coffee received Geographical Indication (GI) certification for its quality coffee beans grown on Doi Tung. This reinforces consumer confidence, provides an overview of the production process, and also guarantees that DoiTung Coffee will remain the property of the Doi Tung community forever.
Other parts of macadamia can be used for a number of purposes and innovations that lead towards the zero waste goal. Its green husk can be used to make compost or soil cover to help maintain moisture levels. Its shell can be burned as biofuel for use in the macadamia processing factory and the DoiTung handicraft production centres. Ash from burning macadamia shells can also be mixed with water for an experimental ceramic glaze that creates an interesting new colour.
