"The circular economy gives us opportunityto build a system that can run in the long term,and the time is right for it to reach scale."-Ken Webster




This project is a speculative sustainable innovation based on a real-life small-scale business that I established in Queen Victoria Market. The business specialises in selling coconut-themed drinks and it generates coconut waste. I design this system for a flagship store of LELENÜT in a possible future scenario. The goal is to convert the coconut waste generated by the store into coconut 3D printing filament and further produce customisable products to sell to customers. ​ The project mainly consists of four development parts, which are detailed below. It follows a logical progression: journey maps of coconuts and customers, 3D filament fabrication, production line design & CAD modelling, and 3D printed cup design with a prototype using coconut filament.



Outcome 1. Journey Maps

Outcome 2. DIY Coconut Waste Filament 

Outcome 3. Coconut Filament Cup Prototyping

Outcome 4. Production Line CAD Model

From outcomes 1 to 4, the entire speculative design progress encompasses the following four progresses of outcomes. The purpose is to theoretically validating mass-manufacturing coconut waste filament using freshly discarded coconut waste.
