Biogas is a renewable source of energy generated from both animal and human excreta as well as green waste. A renewed material is produced by collecting waste materials which are going to be processed in a digester. The liquid waste can be used as an organic fertilizer while the energy produced will be used to light households. Converting Biogas waste into a source of power is no longer a scientific wonder. It is widely implemented in different countries worldwide including the African Nations.
Implementation
The biogas campaign is being backed up by The Environment Africa and Progression, Two Harare Environment and Development-centered civic organizations.
In 2013, project leader Kudzanai Gwande of Environment Africa states that the campaign is still in the process of introduction, demonstration and implementation in order to attract the interest of many communities. Since the technology is new to everyone, the Biogas project still has a lot to prove in order to gain overall acceptance.
The project covers open forums on every demonstrations where the people involved can share their views and experiences regarding biogas use. The demonstrations also serve as a platform where the number of people who are open to the idea will be counted. So far, the majority of the beneficiaries are open to accept this form of technology.
As far as energy processing is concerned, a minimum of 5 cows are needed to collect the required amount of waste products to be converted into energy. Other than cattle, an average household can also use waste products gathered from goats or chickens.
The benefits
With this program, African households can have an alternative source of energy other than using wood. Biogas energy can be used for typical everyday necessities like cooking, heating and lighting. Saving trees directly contributes to the worldwide efforts to lighten the effects of global warming. Too much production of greenhouse gases such as methane through anaerobic decomposition will be reduced as well.
The production of renewed energy alone can also directly contribute to environmental preservation. The liquid waste secreted from the digester can be used to fertilize crops, fruits and trees. With this, the excessive use of artificial fertilizer will be reduced.
Due to the fact that the produced energy is naturally clean, the widespread of respiratory diseases will also be lessened.
This new form of technology is not just environmental friendly, it is also affordable even to those who are earning less. Before the Biogas project was developed, a huge amount of waste product from animals is just being dumped without knowing its potentials. It will only be a matter of time before the entire Africa will embrace this kind of development. When that time comes, Africa will be the biggest contributor as far as worldwide environmental conservation is concerned.
