Case Study


CDM Projects – Tapioca

The tapioca processing industry is considered to be one of the largest food-processing industrial sectors in South East Asia.

The growth of the tapioca starch industry has resulted in heavy water pollution as it generates large amount of solid waste and wastewater with high organic content.

A recent biogas capturing project in Sumatra, Indonesia demonstrates how this industry can become more sustainable and contribute to global greenhouse gas abatement strategies.

Viridis Solutions’ General Manager, Steve Harding, played a pivotal role in delivering the project.

It is now providing a clean energy source to replace fossil fuels and mitigating nearly 200,000 tonnes of CO2 each year.

Both sites involved in the project now have four-megawatt power generators which use the methane biogas as a fuel source.

In addition, the project has reduced odour from the sites and provided an alternative treatment of wastewater from the tapioca industry.

Steve Harding’s involvement in every facet of the project included building a strong relationship with the local community and workforce.

The project work included design and construction of:

• Anaerobic lagoon
• Cover for anaerobic lagoon
• Biogas harvesting
• Biogas scrubber
• Biogas delivery to generator sets
• Chemical dosing
• Associated civil works
• Associated mechanical works
• Associated pipe work.

This initiative is actively reducing global warming by capturing biogas which would otherwise have dispersed into the atmosphere.
