While 1/8 of the world population is facing the hunger problem, the global food industry is wasting an estimation of 1/3 or 1/2 of all food produced. In the coffee industry, the number is even worse. We are using only 4% of the whole coffee plant, and the coffee ground produced from those 4% is also binned.

Caleb Ng and Joshua Ng, founders of Twins Kitchen / Common Ground, know how serious food industry’s wastage problems is from the first hand, as chefs and restauranteurs as well as experienced food consultants. They therefore feel the need to foreground the issue and offer creative solutions to change the food ecosystem nowadays.

From social projects like “XCHAGNE: Social Gastronomy” in Oil Street Art Space in Hong Kong, to a recent pop-up kitchen with upcycling coffee waste ingredients in Beijing, they have been working actively on bringing the problems to the mass audience in a friendly approach.

Through this design dialogue, they would like to share some creative alternatives and solutions from their current projects in Hong Kong and China as to how to produce less waste and upcycling waste for other purposes through food design.

“Waste is a failure of imagination.” This is a famous quote from Silo, a zero food waste restaurant in Brighton. Twins Kitchen hopes to deliver the same message to the audience that they can pursue a better living while creating a sustainable food business without unnecessary wastage.
