Dawei Cao / RMIT University

Transforming coconut waste into sustainable products - pioneering a circular economy system for a greener future.

My entry showcases a groundbreaking speculative circular economy system focused on transforming coconut waste into sustainable and customisable products. Through innovative processes, I convert coconut waste into reusable materials, which are then used to create aesthetically appealing products. This circular approach reduces waste and offers an eco-friendly solution for coconut-based businesses. The project aims to inspire other businesses to adopt similar sustainable practices while contributing to a greener future. By utilising scientific principles and creativity, we've designed a system that benefits the environment, society, and the economy, making a tangible impact on the world.

Design Brief:

The design aimed to address the increasing issue of coconut waste generated by LELENÜT, a small-scale business specialising in coconut-themed drinks. The problem was to develop a sustainable circular economy system for a speculative flagship store, focusing on three key objectives: 1) Converting coconut waste into reusable materials, 2) Transforming these materials into aesthetic, sustainable, and customisable products, and 3) Integrating the system as a decorative element within the speculative flagship store.

The intended outcome was to create an innovative solution that not only reduces waste but also transforms it into valuable resources. By successfully producing 3D printing filament from coconut waste and designing customisable products like cups, the project demonstrated the potential for a sustainable circular economy system in the food and beverage industry. The ultimate goal was to inspire similar businesses to adopt similar practices, contributing to a larger societal shift towards sustainable practices and a greener future.

Design Process

The design process commenced with extensive research and information gathering about the current flow of coconuts in LELENÜT's operations. This helped identify areas for improvement and the basis for developing a feasible circular flow concept, aligning with the project's design brief.

Next, the project focused on the crucial step of converting coconut waste into reusable materials. Multiple experiments and tests were conducted to dehydrate the waste, leading to the creation of fine coconut waste powder. Through various treatments like washing, drying, oven-dehydrating, smashing, grinding, and sifting, the project successfully produced 3D printing filament using 9.1% coconut waste mixed with PLA, a 100% biodegradable material. This innovative approach showcased the project's commitment to sustainability and exceeded the design brief's expectations by transforming waste into a valuable resource.

With the filament in hand, I proceeded to create customisable products. Cups were chosen as the target object, and several iterations of drawings and CAD modelling were developed. The final design featured a set of four cups, each inspired by one of four basic shapes. The team used the coconut filament to 3D print the cups, achieving excellent outcomes that surpassed initial expectations.

For the final step, I developed a 3D model of a production line for the speculative flagship store. This theoretical mass-manufacturing process showcased how the circular economy system could be integrated into the store's operations, thereby meeting the design brief's emphasis on practical implementation.

Throughout the design process, the project demonstrated professionalism, attention to detail, and a continuous improvement mindset. By meeting and exceeding the design brief's objectives, the coconut waste circular economy system showcased an innovative, sustainable, and practical solution that can inspire businesses to adopt similar circular economy practices.

Design Excellence

The design's functionality lies in its ability to convert coconut waste into reusable materials and create customisable, aesthetically pleasing products like 3D-printed cups. The system's accessibility ensures ease of implementation for businesses seeking to adopt circular economy practices.

Moreover, the project prioritises safety throughout the design process, ensuring that the waste treatment and filament production procedures are carried out with precision and adherence to safety protocols. The use of 100% biodegradable materials demonstrates a commitment to sustainability, contributing to environmental protection.

The user experience has been thoughtfully factored into the final design solution. The customisable cups offer users a delightful and personal touch, making them feel more connected to the products. Additionally, the focus on 3D printing and sustainable materials aligns with the growing consumer demand for eco-friendly and innovative solutions. This holistic, high-quality user experience elevates the project beyond just a waste management system, making it a thoughtful, enjoyable, and sustainable journey for both the business and the end-users.

As a pioneering circular economy system in the food and beverage industry, this project sets a new benchmark for design excellence not only in Victoria but also for Australia and internationally. Its innovative approach to converting bio-waste into value-added products showcases the potential for circular economy practices to create positive impacts on both businesses and the environment.

With its combination of functionality, aesthetics, sustainability, and user-centric design, this project stands as a testament to the power of good design. Its potential to inspire other businesses, both within Victoria and beyond, to embrace circular economy practices and invest in professional design makes it a trailblazer in design excellence on an international scale. The project's commitment to making a positive difference in the world sets a new standard for design excellence that will undoubtedly create great impact in the industry and beyond.

Design Innovation

The coconut waste circular economy system project stands as a testament to design innovation, addressing the problem of coconut waste in a truly imaginative and groundbreaking manner. By converting coconut waste into reusable materials and creating customisable 3D-printed cups, the project not only tackles waste management but also offers a unique solution to promote sustainability and circularity.

One of the project's most innovative aspects lies in its world-first creation of 3D printing filament from freshly discarded coconut waste. Through a series of experiments and tests, the designer successfully developed a DIY 3D printing filament made from 9.1% coconut waste PLA, a 100% biodegradable material by using household equipment. This groundbreaking feature not only reduces the environmental impact of coconut waste but also opens up new possibilities for sustainable 3D printing in various applications.

Moreover, the design's user-centered approach ensures that it caters to individual needs and preferences. The customisable cups, inspired by four basic shapes, provide a personalised touch to the end-users, offering them a delightful and connected experience with the brand. The project creatively blends aesthetics, functionality, and sustainability to address users' desires for eco-friendly and innovative products, setting a new standard for user-centered design solutions.

The design considers the entire journey of coconuts, from waste generation to filament production and cup customisation. By optimising each step of the process, the project maximises the potential of circular economy practices in the food and beverage industry. Its innovative and original approach to transforming waste into valuable products challenges traditional waste management practices and sets a new benchmark for sustainable design solutions.
