Collaborators: Team of 4, in collaboration with Sankoya Technologies

Design a retrofittable system to filter and transport solid waste with minimal agitation, compatible with traditional toilets, and integrate with Sankoya's treatment system. 

• Develop a retrofittable toilet system that can separate and transport waste directly to an on-site treatment unit. 

• Minimize waste agitation and ensure compatibility with existing bathroom layouts.

• Enable mechanical preprocessing (maceration) to support downstream treatment efficiency.

• Designed a retrofittable toilet system to separate and transport solid waste with minimal agitation.

• Modelled a custom dry macerator in SolidWorks for effective waste preprocessing.

• Built and tested prototypes using 3D-printed components and surrogate waste materials.

• Created detailed part drawings with proper GD&T for client deliverables.

• Successfully demonstrated mechanical feasibility with printed prototypes. 

• The conveyor operated reliably with simulated waste input.

• Macerator achieved the target paper breakdown 

The project emphasized the need to balance durability, manufacturability, and energy use in a practical design. Iterative prototyping and testing were essential in refining the system, and the experience strengthened our ability to solve real-world problems with user and client needs in mind.
