Nienke Hoogvliet

Born and raised in The Hague, Nienke Hoogvliet has an innate love for the sea and its inhabitants. Her great-grandparents were tailors and also her mother has a way with needles and thread. At Nienke’s parental home, there were always various textiles hanging around, waiting to be finished. The connection to the sea and the textile industry, combined with an inspiring idealism, has been passed on from one generation to the next, leading Nienke to study in the creative industries. A talented artist, she graduated from the Willem de Kooning Academy in Rotterdam in 2013 and immediately founded her own design and materials research studio: Studio Nienke Hoogvliet. Having discovered the enormous potential of seaweed as a sustainable resource, Nienke is dreaming of a world where we wear clothes made out of seaweed yarn and dye. She has shared her ideas on seaweed and natural dyeing techniques in books such as SeaweedResearch and H.E.R.B.S. Raising awareness about our waste economy, Nienke’s work has been exhibited all over the world in museums such as Centre Pompidou (Paris), Central Museum (Utrecht), Cooper Hewitt Design Museum (New York), Textile Museum (Tilburg), Victoria & Albert Museum (London), etc.

Dorien Derksen

Dorien Derksen is an expert in marine and plant-based colors. Dorien has been researching natural dyes from plants, algae, and micro-organisms since 1996 publishes about this. Dorien, Anne & Nienke found each other in their mutual ambition to investigate the possibility to use seaweed as a sustainable locally produced source for dye. Dorien is convinced that the current way of using dyes in textiles is not sustainable. Since 1950, the dyes used for textiles are exclusively synthetic dyes. These dyes are made in low-wage countries. Not all dyes are safe and less so for it environment they end up in, both during production but also after application, think of wear of clothes in the washing machine. In addition, the current chain is extremely fragmented and certainly not sustainable to name.

Our fascination for seaweed colors

We have always had a fascination for colors, textiles, seaweed, and sustainability. That’s why we decided to upscale the artisanal seaweed dye process to an industrial level. Our aim is to replace as many dangerous synthetic dyes with our seaweed dyes as possible.

The sea has so much to offer – and it needs protection now more than ever. 

Seaweed, one of the sea’s most recognizable – albeit underrated – inhabitants, has been utilized, harvested, and cultivated in coastal communities for centuries. Yet, only recently, seaweed has emerged as a novel resource for the textile industry. 70% of our world is water, so there’s a lot of seaweed for our dyes. It doesn’t need precious agricultural ground or freshwater to grow. It even cleans the air from CO2 and produces oxygen. 

At Zeefier, this is what keeps us going every day.
