A local entreprenuer in Tanzania has devised a solution that seeks to eliminate all the problems associated with unsafe/unclean water and sanitation. It will help locals avoid related diseases. What's more is that his solution is low-cost and requires no power compared to other water treatment technologies. It is also made from local materials, recyclable, and versatile in that it can be tailored to treat water in vartually any location/area. The nano-filter combines nano-filtration technologies with sand-based water filtration techniques. It has already been rolled out in the market and is gaining ground.

Adoption of biomass power generation technologies in Africa has been challenged by a variety of factors including high capital costs and lack of feedstock. However, with biomass contributing to only 5% of power production in the continent, these projects hold a promise to helping boost the much needed power in developing world. It is not only the largest biomass power plant in Africa, but Gorge Farm AD Plant in Kenya will be Africa's first anaerobic digester.

The traditional plastic bottle is associated with high carbon emissions, and that is set to change with the onset of a PET bottle made of 100% plant materials. The bottle was launched earlier this month by Coca Cola, and is set to help the company eliminate dependency on fossil fuels for production of PET bottles. Coca Cola has, through the previous PET bottle made of 30% plant material, achieved substantial cuts on global emissions and the new development to produce a 100% plant bottle is a key to sustainable packaging.

Sanitation and water treatment in the developing world is set to change with the onset of the Omni Processor. The Bill Gates and Melinda Gates Foundation have decided to invest in a machine that turns sewage into drinking water and can also generate energy.  Just as importantly it is relatively low-cost, making it a technology that can be rolled out quickly in emerging economies.
