The Ocean Cleanup is a nonprofit engineering environmental organization based in the Netherlands, that develops technology to extract plastic pollution from the oceans and intercept it in rivers before it can reach the ocean. After initial testing and prototyping in the North Sea they deployed their first full-scale prototype in the Great Pacific Garbage Patch. It ran into difficulty after two months and was towed to Hawaii for inspection and repair. In June 2019, their second prototype system was deployed. They also deployed their river technology, the Interceptor, in two locations in 2019, revealed the project publicly in October 2019, and deployed another in 2020. In 2021 they announced that the prototype testing of System 002 was successful.The organization conducts scientific research into oceanic plastic pollution. It was founded in 2013 by Boyan Slat, a Dutch-born inventor-entrepreneur of Croatian and Dutch origin who serves as its CEO. It has conducted two expeditions to the North Pacific Gyre, the Mega Expedition and the Aerial Expedition, and continues to publish scientific papers. Their ocean system consists of a floating barrier at the surface of the water in the oceanic gyres, that collects marine debris as the system is pushed by wind, waves and current, and slowed down by a sea anchor. The project aims to launch a total of 60 such systems, and they predict this capability could clean up 50% of the debris in the Great Pacific Garbage Patch in five years from full scale deployment.In late October 2019, The Ocean Cleanup announced a new initiative, the Interceptor, to tackle the trash problem closer to the source, with plans to prevent 80% of riverine trash coming from 1000 rivers worldwide.

Het Nieuwe Instituut (HNI, English: The New Institute) is a cultural centre in Rotterdam, the Netherlands. It focuses on architecture, design, and digital culture. HNI is in a building designed by Jo Coenen at Museumpark 25 in the centre of Rotterdam, adjacent to the Museum Boijmans Van Beuningen. The building contains a shop, exhibition space, study centre, and archive, as well as the Sonneveld House (a prime example of Nieuwe Zakelijkheid architecture), a pond, and a small park.

The Groothandelsgebouw (meaning Wholesale Building or Offices) is an extensive building and monument in the center of Rotterdam, Netherlands next to the Central Station of the city. Completed in 1953 it is one of the first major buildings built after the bombing of Rotterdam in the Second World War. Because during the war much business was lost, there were early plans for new office space. The idea for a new building came from a wholesaler Frits Pot who realized that a rather large building would be smaller than tens of buildings of separate wholesalers. During Christmas 1944 he made a sketch and on May 4, 1945 it was discussed in the Chamber of Commerce. Together with architect Hugh Maaskant and (later Director) G. Thurmer he made a study trip to Chicago, USA in 1947. The building is modeled after the Merchandise Mart in Chicago. The final building fitted exactly in the vision of Rotterdam and the post-war reconstruction of the city. The Wholesale House was an innovative project for that time: the very large building was designed not only by many companies, but included a complete route through the building. During the construction phase in 1951 a grand cafe-restaurant, conference center etc. was installed. The building itself was completed in 1953. Characteristic of this building is a constant grid of concrete columns in which the building rests. Center-to-center distance of the columns is 6.72 meters. The columns are octagonal. Supporting the outer walls are approximately 65 inches, the inner columns are about 85 centimeters. The building has 5 entrances, marked with the letters A through E. The main entrance is located at the A station 45. The entrances D and E (sometimes called the back) are on Conrad Street. The building also lies on Weena Street. Exceptions to the constant grid of the wholesale building are the spaces created by the oblique lines of the building. These (imaginary) lines are about the length of the A wing and the imaginary line from D to C.

The Universal Esperanto Association (Esperanto: Universala Esperanto-Asocio, UEA), also known as the World Esperanto Association, is the largest international organization of Esperanto speakers, with 5501 individual members in 121 countries and 9215 through national associations (in 2015) and in official relations with the United Nations. In addition to individual members, 70 national Esperanto organizations are affiliated with UEA. Its current president is the professor Duncan Charters. The magazine Esperanto is the main organ used by UEA to inform its members about everything happening in the Esperanto community. The UEA was founded in 1908 by the Swiss journalist Hector Hodler and others and is now headquartered in Rotterdam, Netherlands. The organization has an office at the United Nations building in New York City.

The Hector Hodler Library is one of the largest Esperanto libraries, with approximately 30,000 books in addition to periodicals, manuscripts, photos, music, and other collections. It occupies three rooms in the central office of the Universal Esperanto Association (UEA) in Rotterdam, Netherlands. The Swiss Esperanto Society opened the library in Switzerland in 1908. In 1912, the library came into the possession of Hector Hodler, the founder of UEA, and after Hodler's death in 1920 the library remained under the management of UEA in Switzerland. In 1947, the library was renamed the Hector Hodler Library, and when UEA headquarters relocated to Rotterdam, the library was moved there in 1960. Other major collections of Esperanto books are at the International Esperanto Museum, the Montagu C. Butler Library, the Center for Documentation and Study about the International Language in Switzerland, and the German Esperanto Library.

The Netherlands Architecture Institute (NAI) was a cultural institute for architecture and urban development, which comprised a museum, an archive plus library and a platform for lectures and debates. The NAI was established in 1988 and was based in Rotterdam since 1993. It ceased to exist in 2013, when it became part of Het Nieuwe Instituut. The NAI was a private organisation with a government brief, which was to manage the collection of archives that document the history of Dutch architecture. As a sector institute for architecture it was tasked with supporting the professional field. The building also housed a bookshop and a cafe.

Depot Boijmans Van Beuningen (initially called 'het Collectiegebouw' (Collection Building), popularly called 'The Pot') is an art depot of Museum Boijmans Van Beuningen in Rotterdam. It is the first publicly accessible art depot in the world. It is a 39.5 meter high, bowl-shaped building that is covered with reflective plates, so that a more or less contiguous, reduced mirror image of the environment can be seen, whereby one can look over the surrounding buildings. To guarantee the privacy of patients of the adjacent Erasmus MC, a number of plates have been made matt on that side. Some rooms where daylight is needed are also fitted with normal glass. An aluminum-coloured IKEA bowl served as inspiration for the shape of the building. The 'Blanda Blank', a slightly shiny serving dish made of stainless steel for 3.99 euros, happened to be on the table as a sugar bowl during preliminary discussions about the design for the building. The first pile went into the ground on March 17, 2017. The building has seven floors. On the roof is a restaurant with 120 seats. The building contains 1 664 mirror panels with a combined surface of 6 609 m². In addition, there are four restoration studios. Inside, part of the collection is displayed in thirteen display cases. In October 2021, the costs for the building were estimated at over ninety million euros. On November 5, 2015, the Rotterdam city council approved the change to the zoning plan in the Museum Park, allowing the plans for a special art depot to be realised. There used to be 255 Acacias trees on the site of the building. According to some experts, they were in a bad condition and could only survive if they were moved to the municipal tree depot. Others disagreed with that view, saying that the new building is destroying the park.Depot Boijmans Van Beuningen was designed by the Dutch architectural firm MVRDV. The entire deposit collection of Museum Boijmans Van Beuningen (more than 151,000 objects housed together, arranged in fourteen storage compartments with five different climates) is stored here and is publicly accessible, on a total floor area of 15,541 m². Financially, the realization was made possible in part by the 'De Verre Bergen foundation' with a donation of €17 million and a loan of approximately €35 million during the construction phase. The intention is that the exploitation will be paid for from entrance fees and from income from the rental of depot space to private art collectors; 15 percent of the floor space intended for art is reserved for this purpose.
