Environmentally friendly disposal of biomedical waste

There is hardly any waste management in many hospitals and communities around the world. Waste is just thrown on the street or dumped behind somebody’s house. Especially in hospitals the infectious waste is a big problem concerning drinking water quality and health. Therefore, TeoG opted to start their pilot projects in Ghanaian hospitals.

The costs of materials and wages vary widely from project to project.
Costs of approx. 2,000 € arise for the material of the waste yard and the incinerator. 500 € can be calculated for transportation of material and approx. 1,000 € in addition for wages, waste bins and other costs.
The total project expenditure is therefore approx. 3,500 € excluding travel costs.
