The emissions are unfriendly to the environment in industrial production and other human activities, and thus leading to global warming and destruction of the ozone layer, among other negative effects.
It is on this backdrop that industries in both developing and developed world are switching to eco-friendly energies as they seek to join the global campaign of reducing carbon emissions.
One such industry is the Morogoro-based Tanzania Tobacco Processors Limited (TTPL) which plans to convert its heavy furnace oil (HFO)-fired boiler to biomass by June, next year, according to its Engineering Director Henry Lambert.
The biomass boiler would be delivered in Tanzania by mid-December, this year whereas installation and commissioning is expected by June, 2015.
At the processing plant, the boiler is used for steaming and drying of tobacco leaves.
"The conversion from HFO to biomass is in line with TTPL and its major shareholder, the American based Universal Leaf Inc's.
Environmental policy to reduce its carbon footprint," Lambert said in an interview.
Not only would the plant reduce emissions but it would create more jobs and significantly cut down costs that TTPL has been incurring to purchase diesel to run the current boiler.
"The cost of purchasing and installing the biomass boiler is $2 million dollars while we are currently using the same amount just to buy fuel per annum.
