Let’s prevent ocean-bound waste!
2024 - 2025
In collaboration with: Zushi City, Shikokuchuo City, Nagasaki Prefecture, Yamazaki Lab
Studies suggest that plastics accumulate on land and in rivers, forming a long-term source of marine litter even if the primary source of mismanaged plastic waste is resolved. Around 80% of marine litter originates from the land, much of which accumulates in rivers and is eventually transported to the ocean.
In addition, in Japan specifically, around 30% of the mainland coastline is covered by concrete tetrapods, designed to minimize coastal erosion by dissipating the power of waves and currents. Due to their large size and interlocking structure, the deep crevasses in between tetrapods is the perfect place for plastic to accumulate. Cleaning these areas is an important part to reducing marine litter, but both rivers and tetrapods tend to be difficult to access and clean.
OMNI Delta is a project that encourages people to engage with and participate in marine litter reduction strategies by making river and tetrapod cleaning more approachable. With supervision from local stakeholders, we are working on design interventions to address these issues and make the activity more accessible.
