Renewable energy is a kind of energy produced from any source that can be maintained in a constant supply over time. Among these sources biomass is considered extremely important since it could be a suitable sustainable alternative for conventional fossil fuels.



After grape seed oil cold pressing, approximately 80% of the seeds are left as a by-product in the form of compressed seed cake. This cake can be milled, and pelletized to form a renewable energy biomass pellet with excellent thermal properties.

The addition of the 3000 tons of biomass pellets would result in a saving 2,500 tons of fossil fuels, and CO2 reduction of

SANO will manufacture grape seed renewable energy biomass in 6mm and 8mm PELLET forms, and although the production volumes are relatively low at just over 4000 tons, these numbers are expected to increase significantly with the addition of further raw materials over the next few years.

Grape Seed Cake Pellets is 76% as efficient as traditional fossil coal (27 MJ/kg), but what makes the Grape Seed Cake Pellets particularily impressive, is the fact that it only has 4,5% ash content, when compared to coal's 15% ash content.

SANO believes their Grape Seed Biomass product will offer companies with a great alternative to Wood Pellets and Traditional Fossil Coal, in terms of Thermal Efficiencies;  Energy Mass Ratios; Storage Requirements; and Enviromental Sustainability responsibilities.




SANO has invested in innovative green technology whereby they can capatilize on their green biomass by-product, but more significantly they can reduce their carbon footprint on the environment.


The drying of all grape seed raw materials will be performed by means of purpose designed BIOMASS FUELLED AIR DRIERS, which involves blowing air heated by the seed cake biomass pellets through the seeds until sufficient moisture is extracted. SANO will also use their biomass by-product as the fuel to heat water for CIP cleaning equipment and for factory general water heating requirements.


By using this environmentally friendly renewable energy fuel source, SANO can reduce CO2 emmisions by over 7000MT per year.



Laboratory results have indicated  that Grape Seed Cake Pellets has a Gross Calorific Value (GCV) of 20,51 MJ/kg, which is 20% more efficient than wood  biomass pellets, which only has a CGV of 17,3MJ/kg.

Furthermore, Grape Seed Cake Pellets has a bulk density of 750-800 kg/m3 wheras Wood Pellets has a bulk density of 550-650 kg/m3, meaning Wood Pellets require 25-35% more space to store compared to the grape seed biomass.


Traditional Biomass Wood pellets presently offer a price advantage of -14.3% as opposed to extra light heating oil, and -43,3% as opposed to natural gas, making the fuel a high demand commodity. The Grape Seed Biomass will be marketed at the same commodity spot price as Wood Pellets, and will thus give customers considerable savings per Mega Joule as well as less storage requirements.
