Challenge

 

Nearly 9 million tons of plastic enter our oceans each year, mainly through rivers. This plastic collects in huge patches and slowly breaks down, impacting more than 600 marine species and introducing toxic pollutants into the food chain. Removing this plastic manually would be costly, time-consuming, and lead to massive amounts of new carbon emissions. Passive cleanup systems backed by AI and machine learning can stop plastic from reaching the ocean—and remove the plastic that’s already there.

Solutions

 

The Ocean Cleanup uses two cleanup solutions—one for rivers and one for oceans—to remove tons of plastic from the world’s waterways. To locate plastic debris, The Ocean Cleanup uses bridge-mounted cameras to photograph floating objects and identify plastics. The Interceptor, an autonomous collection unit, is positioned to collect the plastic for removal. In the ocean, sensors attached to passive cleanup systems collect data on winds and currents. An algorithm runs simulations to show how these cleanup systems move through the ocean. The Ocean Cleanup plans to combine these two systems at scale to reduce ocean plastic by 90% by 2040.

How The Ocean Cleanup uses Azure for river monitoring

•    Azure Machine Learning for training and deploying image recognition models.
•    Azure Functions for conversion of ingested data.
•    Azure Service Bus for coupling of microservices.
•    Azure Storage for storing many types of critical data (e.g. metocean data, image data, data from test campaigns).
•    Azure SQL as well as Azure PostgreSQL for storing processed data.
•    Azure Kubernetes Service for scalable processing of remote data, computation of agricultural and economic models, and other geospatial processing.
•    GPU optimized Virtual Machines for training, evaluating, and running plastic debris detection models.
