Coconut shell activated carbon can be a green choice, offering a truly sustainable product for the long term. As long as coconut plantations are managed in a sustainable manner, the resource is fully renewable.
On the other hand traditional charcoal manufacturing methods are far from environmentally friendly, since the process itself releases large quantities of volatile organic gases into the atmosphere, including methane, which is a particularly potent greenhouse gas.
Haycarb has therefore developed their own industrial charcoaling operation at the Badalgama site in Sri Lanka. Winning the prestigious National Science and Technology Award for Eco-friendly processes in 2007, the Recogen business now produces more than 25% of Haycarb’s charcoal needs.
The Recogen plant uses special vessels for the heating of the coconut shells in the required conditions for ideal charcoaling. The methane given off is collected, and then combusted in a boiler. A steam turbine then powers a 1 MW generator, which is connected into the Sri Lankan national grid. The multiple benefits if this unique facility can be stated as:
- Allowing charcoaling even in adverse weather conditions when traditional methods cannot take place, thereby smoothing the supply chain.
- Consistent process giving reliable char quality.
- Using traditional waste materials from domestic sources, collected by new private collection enterprises which provide jobs in rural areas.
- Generating electricity from renewal resources.
- Saving of the equivalent of 46,000 tonnes per annum of carbon dioxide release.
- Generating tradeable carbon credits, registered under the UNFCCC system.
Our customers can also benefit from this technology by using activated carbon with a lower footprint, either through partial use of this char, or through exclusive use in the NeutroCarb branded products.
