Problem

Guanidinium Thiocyanate (GTC) waste from viral load testing is corrosive and improperly disposed of in many African countries, often discharged untreated into sewer systems.

Solution

A bioremediation approach using thiocyanate-degrading microbes (e.g., Thiobacillus spp.) is developed for treating GTC waste. Systems can range from low-tech shake flasks to bioreactors.

Added Value:

The solution provides a nature-based, low-cost, and energy-efficient method for hazardous waste disposal. It enables safe, scalable waste management and protects water systems.

Contribution to Global Biosecurity:

This low-cost bioremediation system neutralizes hazardous Guanidinium Thiocyanate waste using naturally occurring microbes. By eliminating toxic laboratory by-products before they can be misused or released into the environment, it contributes to global biosecurity and environmental safety through sustainable waste neutralization.
