Nadero tackles the problems of poor sanitation, deforestation and unsustainable use of charcoal and firewood, as well as the use of harmful chemical fertilizers. By constructing biodigesters and training the customers on management, sanitation is improved.

Nadero's biodigesters are custom-made, ranging from portable poly-tanks to underground tanks. Customers can arrange disposal of waste with Nadero. The large amounts of biowaste produced are converted to cooking fuel and organic fertilizer at low costs. The fertilizer is sold to other farmers. Nadero hopes to establish its own farm and utilise the biofertilizers to create organic produce for local markets. Its organic vegetables will serve as an incentive for customers to provide the company with their waste.
