Stop at source technology

RIVER DEBRIS CATCHER (RDC) + RAMPED BUBBLE WALL (RBW) Think Ocean Hybrid System

Think Ocean attempt to stop, capture and retrieve up to 92% of the plastic on its way to the ocean, in the longest river in Europe. Novi Sad in Servia will be the part of the Danube River that will host Think Ocean's test site as part of the European Commission "Horizon Mission".

Restoring the health of world’s waterways and addressing the accumulation of waste in its oceans is a massive challenge that we, Think Ocean, want to tackle from inside out or “from inland to oceans”.   

Our Mission

Demo 5 - Novi Sad sampling sites on the Danube and connecting channels 

Location: Novi Sad, Serbia |  Connected rivers: the Danube 

The Danube is a major EU river at 2850 km, running through 4 capital cities and emptying into the Black Sea.

Technologies to be demonstrated: Detection of L and P with drones, removal of L/P/MP with floating systems. 

Partners involved: UNSFS (site manager), UoA, EDEN, LEQ, TOC (Think Ocean)

Opportunities for impact: Novi Sad lies on the River Danube, between two protected wetland nature reserves, "Begačka jama” and “Koviljsko-petrovaradinski rit”, which are approximately 15 km upstream and downstream of Novi Sad, respectively. In addition to the Danube, Begačkajama receives water from a drainage canal to the north, which runs close to a small unregulated landfill.

In the area of Novi Sad, wastewater is directly discharged into the Danube, thus expected to show higher amounts of pollution than at the other demo sites. The removal solutions to be demonstrated at this site are in-river, where they can address the river pollution directly and 

realise impacts in the absence of WWTPs. 

Channels leave and join the Danube at many points along the river, providing areas of low flow and of increased turbulence.

Monitoring and removal activities will be split between the upstream and downstream locations, in order to observe the impact of the city of Novi Sad, which is home to approximately 340,000 people within its wider urban area.

At the same time, the effects of the landfills and other unregulated industrial plants will be investigated.

The samples sites are shown in the figure, where the area depicted is approximately 42 x 16 km.

UNSFS will manage the organisation of the demonstrations, including permitting and sampling.  UNSFS has established sampling points along the Danube from currently running monitoring activities performed for regional authorities and will use standardised sampling and monitoring protocols.
