Industrialization has put a strain on our environment due to pollution, deforestation and loss of biodiversity.  The right technologies can help us develop our economies without damaging the environment.

Tanzanian innovator rises to solve water sanitation problems

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.

The PlantBottle - new plastic bottles made completely from plants

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.

Africa’s rollout of Digital TV and what it means for the environment

Africa is rapidly upgrading its digital television infrastructure. This isn’t just about enabling more people to watch their favorite shows – it’s a big move that will help spur economic development through an improved mobile and internet communication infrastructure.  As covered previously on Cleanleap, analysis shows that improved internet connectivity in Africa could lead to a $300 billion contribution to GDP by 2025.

Automated weather stations in Africa: fighting the effects of climate change

The Kenyan Meteorological Service with the TU Delft/Oregon State University are working on a project Trans-African Hydro-Meteorological Observatory (TAHMO) to develop a solid network of automatic weather stations in Kenya. The project intends to create a technological solution through a cost effective network of hydro-meteorological measuring stations that will map and predict water and weather in the region.

Closing the plastic loop

We are producing an ever increasing amount of waste, including a large amount of plastic waste that is going straight in our oceans. A recent study estimated plastic waste produced by 192 coastal countries in 2010 was around 275 million metric tons (MT), with 4.8 to 12.7 million MT of this waste entering the ocean. Can our oceans absorb all our CO2 as well as this much plastic? Recycling plays an important role, both in conserving our precious resources and reducing the amount of waste going to landfill.

Fire and ice: will methane hydrates be the future of energy or bring on the next apocalypse?

At the bottom of our oceans and buried deep beneath permafrost surrounding the arctic circle is a vast store of methane – a natural gas produced by the anaerobic decomposition of millions of years of organic matter. Estimates vary but even conservative figures suggest there may be over a thousand gigatonnes of methane precariously stored as ice crystals under high pressure and low temperature.
