The concept of circular economy is based on three principles: (1) to eliminate waste and pollution, (2) to keep products and materials in use, and (3) to regenerate natural systems. Yet, our current economy is a linear system where too much ‘output’ is still being disposed, incinerated, or sent to landfill. However, more industries and companies start to see the unique opportunities that the circular economy provides and realize the need to future-proof their activities for a decarbonized world. Ultimately, the circular economy aims to redefine growth and focusses on benefits such as limiting the pressure on the environment, encouraging responsible production and consumption of resources, stimulating innovation, and even creating jobs.
With the port of Rotterdam being the largest port of Europe, it may not come as a surprise that it produces a lot of waste and at the same time also collects many residual waste streams from the surrounding areas and incoming ships. Think of plastic and rubbers, biomass, metals, minerals, chemicals, and industrial waste. These streams provide major opportunities for waste valorization that are realized when putting in the efforts to support research and innovation in this field. Two examples to highlight the efforts done in the Port of Rotterdam to stimulate the circular economy:
Europe’s largest renewable fuel plant can be found at the Neste plant site on the Maasvlakte, where Neste operates as one of the world's largest producers of renewable diesel. With its development of the NEXTBTL technology, Neste has been able to produce Neste MY Renewable Diesel™ from refined vegetable oils and residual organic waste.
Neste optimized the chemical consistency so that it can also replace fossil raw material in uses other than traffic fuel. It can be used in ships and airplanes (as a blending component for aviation fuel); in working machines used at mines and construction sites; and even as raw material for renewable plastics or as a renewable solvent in paints.
It can be said that Neste is a frontrunner in sustainability when it comes to renewable diesel, producing 3.5 million cubic meters per year and aiming to reach 5.1 million cubic meters by 2022. With little waste at the end of the production cycle, Neste’s renewable diesel contributes to clean transportation and to the overall reduction of crude oil dependency.
Industrial saline wastewater and residual heat are two of the biggest waste streams in the industrial area of the port. Zero Brine – a collaboration initiative by 22 partners from research institutes, SMEs, construction companies and end-users from 10 countries – aims to close the loop and has created a circular solution that recovers and reuses minerals, like calcium and magnesium salts, from industrial saline wastewater, using industrial residual heat from local industry.
At the demineralized water plant of water company Evides in the port of Rotterdam, a pilot project has taken place with results that show that extraction of minerals is indeed possible and that they are of good quality for selling. Similar results have been achieved at other pilot locations, such as at a mining site in Poland and a textile factory in Turkey.
Ultimately, the use of Zero Brine technology will lead to the reduction in saline wastewater as it is being treated; to a better use of residual heat that would otherwise be discharged; and to saved CO2 emissions that would otherwise have been released in the production of the minerals.
Industries and companies are discovering the benefits of the circular economy and making an impact. Here are three tips for acceleration:
