About MBL

Our Team

MBL brings both experience and youth to the marine biopolymers area, and it was founded, and is led, by two highly experienced executives with a strong record in innovation and development.

In addition, our chairman is also a highly respected and experienced figure in the IB sphere, including in natural polymers and alginate.

Collectively, our seaweed and alginate experience, including expert advisers we can call on in different areas, from seaweed supply to customer applications, amounts to 100 years and more.

Youth also features, and MBL has augmented its original duo with young graduates who are playing their part in taking the company forward in different areas.


Douglas Macinnes

Douglas is one of the two founding directors of MBL and he has been the key technical driver of MBL’s new alginate process from concept to pilot scale, and will lead the development of the full scale plant. He has over 20 years’ previous experience within alginate production, but has augmented his skillset in project management, supply chain management and lean manufacturing.
