Company Vision

Barbados’s Goal is to be 100% Fossil Fuel Free by 2030.




Modern Rum as we know it was serendipitously birthed among enslaved men and women in the Caribbean, and Caribbean rum now dominates the international rum industry. Wastewater from the rum industry is optimal for producing BIO-METHANE via anaerobic digestion. Rum distillery wastewater is the most practical option for large scale anaerobic digestion in a water-scarce Caribbean Island like Barbados.


Bio-methane can cheaply and easily power electric grids and vehicles.


A regular internal combustion engine gasoline-powered vehicle can be upgraded with a CNG kit in 4 hours and drive fully on biomethane.

In addition to rum distillery waste water, a solid, digestible feedstock is also needed for bio-methane production.
We harvested Sargassum seaweed from local beaches and tested it with rum distillery waste.

It was far more promising than other grasses agriculturally grown in Barbados for bio-fuel production.


This is an idea that solves three major problems:

An economic problem: keep sargassum off the beach and save the tourism-based economies

An energy problem: energy security for a 100% fossil fuel free Barbados 

A waste problem: rum distillery wastewater can be re-purposed
