In Ghana, more than US$ 2 billion worth organic foodstuffs were wasted in 2012. About 1.3 billion tonnes of organic food produced globally is wasted annually according to FAO. We aim at converting the wasted organic food into powerful compost that has the power to restore the soil fertility at any quarry site during reclamation to promote biodiversity by using worm species called Eudrilus eugeniae (African Night Crawler) and also to free the environment from any adverse effect generated by the organic food waste. The vermicompost will support plants growth but ecological food chain will also ensure that other organisms follow suite (ecosystem and restoration of biodiversity).
Three experimental controls were set from Vermicompost; normal compost, the stockpiled and mine soil. The rates at which each restores biodiversity at the quarry site were compared. It is already projected that the biodiversity at the Vermicompost site would be restored more rapidly than the other two controls.
The Vermicompost can be transported to any quarry site to reclaim its biodiversity. In more advanced and sophisticated means, holes can be dug and filled with Vermicompost to support plants growth even when mining is in session.
The project won the International contest of the Quarry Life Award 2014 in the category “Innovation and Biodiversity”
