c2renew has created biocomposites for many different customers, across a lot of different industries but the c2cup is the first thing created 100% for us. When our co-founders thought about one of their favorite things - coffee- and brainstormed ideas on how to use coffee in new and innovative applications the idea of a coffee cup made from coffee sprouted and the c2cup was born.
Designing the c2cup
Once we decided we wanted to create the c2cup, we had to come up with a design that would work with pre-existing stainless steel inserts. So a lot of time was spent on Solidworks designing the c2cup until we finally arrived at a cup design that worked well.
The Coffee Biocomposite
To develop the cup, we created a new biocomposite formulation which is a hybridization of a bio-based resin and coffee waste. This coffee biomass not only results in a greener plastic, it also cuts down on cost while maintaining the desired mechanical properties.
To ensure that our material was well suited for the high temperatures of coffee and dishwashers, we moved away from using a composite meant for 3D printing. To prove our material would withstand everyday use we did extensive testing and developed sample plaques to show the mugs texture.
Developing the c2cup
Once we had the biocomposite and cup design, we wanted to develop a proof of concept cup so we used our coffee biocomposite to make 3D printer filament and printed the 1st coffee cup.
After the success of our 3D printed cup we decided that an injection molding tool would be necessary if we wanted to produce a high quantity of c2cups. Since our last Kickstarter (aside from the continued materials development) we worked with a rapid injection molding company that specializes in molding smaller items. This allows us to have the lowest cup production cost and hopefully, with your help, a successful Kickstarter so that we can begin producing c2cups for everyone.
What have we been up to since the last Kickstarter?
Aside from further perfecting the c2cup, we've spent a lot of time developing both c2sensor and Wound Up.
c2sensor uses biocomposites and non-bioaccumulating metals to create advanced micro-sensors than can be used for a variety of farming and agriculture applications. The Sensing Earth Environment Directly (SEED) Sensors that are being developed can monitor salinity, nutrient, pH, and moisture levels of soil. Best of all, since they are made out of bio-based materials the SEED Sensor will biodegrade.
Wound Up is a coffee-based 3D printing filament developed in partnership with 3Dom USA. The final product launched a few days ago and is now for sale on the 3Dom USA website. For more information on the filament check out this video: https://www.youtube.com/watch?v=kY5equ2yxFM
Risks and challenges
One of the risks with any new projects are delays, in our delivery timeline we did provide ourselves with some cushion to give us time to manage delays.Learn about accountability on Kickstarter
