Marja Kok – Sustainability & Promotion

Water without waste is an initiative of Marja Kok, Dutch, who has had a varied career in yachting of which the last 10 years running superyachts after being 7 years a live-aboard together with her partner and being organizer of sailing charters from their own company and for others.  The constant newsfeeds about plastic pollution in the oceans and her own experience on yachts made her willing to make a difference in the awareness and behaviour of the nautical industry. After her latest job as captain of a 32 m sailing yacht, she decided to put her energy in the attempt to reduce the usage of plastic water bottles on superyachts.

Water and yachting have always been an important part of Marja’s life. Sailing from childhood on, she completed in her mid-twenties a wooden seaworthy boat building project together with her partner at that time. After a career in managing author’s rights societies, she became in the year 2000 a charterskipper in the Mediterrenean and Caribbean sea, followed by a life as live-aboard on her own 44 ft sailingyacht together with her partner. They sailed around the Mediterreanean Sea, Atlantic Ocean, Caribbean Sea and along the coast of Central America. In this period her natural concern for nature, environment and sustainability became stronger. Not spilling any drinking water, electricity or food and trying to produce as less garbage as possible, became a natural habit living on a boat often in remote, pristine areas with few garbage disposal areas. Life on a small boat can be a circular economy on its own and is a great lesson for life.


Andreas Buhl – Technical Solutions

During Marja’s research on sustainable and complete drinking water solutions as alternative for plastic bottled water, she crossed paths with Andreas Buhl, at that time general manager of Dutch water purification company Aqua Blu.

Aqua Blu is part of a Dutch industrial group with which Andreas teamed up in 2013 to develop and distribute trustworthy and sustainable purification solution on a global scale.  Andreas has a focus on identifying pollutants within any available water source from boreholes to fancy bottle brands and to develop technical solutions for every situation. To his opinion potable water, nor plastic bottled water can be considered a truly healthy drinking water source.

Before his focus on drinking water Andreas’ has been on bluewater as captain on sailing superyachts. Extensive cruising off the beaten tracks in far remote areas gave him a first hand insight on where plastic ends up, luxury charters and racing on super yachts depicted the tremendous consumptions of bottled water.

Andreas was born and raised in Salzburg, Austria. His technical education started by a dual apprenticeship in plumbing and technical drafting after that he studied Geography and Journalism at the University of Vienna before he set out to sea. After four long educational years in the Netherlands, Andreas is now mainly based on Mallorca, focused on providing complete, sustainable drinking water solutions. To the yachting industry and the domestic market.
