David is the Co-founcer of Dutch renewable energy company Maatschappij Wilhelmina NV - an innovative renewable energy company, turning agricultural waste streams into sustainable energy, while reducing coal consumption, CO2 and methane emissions.

The company is investing US$60 million (RM283 million) to build a TG2 black pellet plant, the first of its kind in the world, that uses empty fruit bunches (EFB) from oil palms as feedstock to produce drop-in coal replacement fuel in Malaysia.
