We can see that the biggest problem that is facing our country right now is the production and distribution of energy, which has become a major challenge, especially for communities, businesses, and even various institutions that rely on self-sufficiency through this energy. Inflation in petrol, diesel, and gas thus increases the cost of transportation.

To overcome this problem, the government has focused on the construction of dams that contribute significantly to the generation of electricity through the water collection system, Julius Nyerere HydroPower Project (JNHPP) and the construction of East Africa crude oil pipelines (EACOP) with the aim of facilitating oil production. But the challenge of access to electricity still exists due to the shortage of rainfall, which is largely dependent on this production. We are also seeing the use of solar power increase rapidly.

In addition, there is still a big challenge facing many citizens, including the cost of accessing this energy, so many remain in the dark, especially in many rural areas. The price of petrol, diesel, and gas has gone up, as has the cost of energy related services.

What can be done to alleviate the energy crisis and waste management?

Tanzania is one of the fastest growing economies in the world, and the increase in electricity and oil energy is especially large in urban areas due to the increase in residential, industrial, and commercial dependence on this energy. In addition, the production of waste has increased to the point of causing environmental distress and pollution due to poor waste collection systems, thus leading to the pollution of many areas.

To address the energy crisis, Tanzania could Introduce Waste to Energy Technology: It is a technology that involves the use of waste to generate electricity, gas, and oil. This involve converting waste into electricity, oil and gas through methods like incineration, pyrolysis, gasification, and anaerobic digestion (student energy, n.d.). Implementing these systems would enhance energy availability, reducing distribution challenges, cut transportation costs, and increasing the availability of gas that can be used in households and cars.

How can these wastes be used to generate energy?

There are various methods used to convert waste into energy and bring about prosperity. These include:-

INCINERATION, which involves the burning of solid waste at high temperatures. The heat generated by the combustion converts water into steam, which then enters the turbine generator and is converted into electricity.

ANAEROBIC DIGESTION: This method uses a system of bacteria that digest household waste (food), animal feces, and manure to produce energy. The results obtained by this method include the production of electricity, motor fuel, gas, and fertilizer. This method of energy production, in addition to the availability of electricity and fuel, will also greatly help the production of fertilizer for use by farmers, thus reducing the cost of importing fertilizer.

PYROYSIS: is the process of heating organic material at high temperatures in the absence of oxygen. Since no oxygen is present, the organic material does not combust. Instead, the chemical compounds (i.e., cellulose, hemicellulose, and lignin) that make up the material decompose into combustible gases and charcoal.

GASIFICATION is a unique process that converts carbon-based material, such as medical waste or biomass, into other forms of energy without burning it. Rather, gases convert solid and liquid wastes into gases through a chemical reaction. This reaction combines carbon-based materials with a small amount of air or oxygen (but not enough to burn the material) and breaks them down into simple molecules, usually a mixture of carbon monoxide and hydrogen.

Let's consider the example of several countries that has continued to deploy waste to energy technologies :-

Sweden, serves as a great example also known as World’s Greenery country. Within a few decades, the country has entirely overhauled waste management, significantly boosted recycling rates, and invested in technologies to convert waste into energy. Since the 1990s, the Swedish government has developed a number of successful initiatives aimed at reducing waste output, raising awareness among industry and citizens, and dramatically lowering emissions. (Igini, 2022)

South Africa
, it has several waste to energy plants including the first landfill gas to electricity project in Africa located in Durban. It generates electricity from methane gas produced by decomposing waste. (UNEP n.d.)

Kenya has also invested in waste to energy projects including the Nairobi integrated solid waste management project. It’s aim is to convert waste in electricity. ( AfDB n.d.)

Lastly, Rwanda. The country’s capital Kigali, has a waste to energy plant that converta landfill waste into biogas which is then used for cooking and electricity generation.(GGGI n.d.)

The examples shows that, Africa is growing interest in Waste to Energy technology for sustainable development, environmental protection and energy security.

By embracing waste to energy technology, Tanzania can enjoy several benefits including:-

~ Implementing waste to energy solution can significantly help in reducing the emmision of methane, a harmful greenhouse gas, thereby improving public health and environmental quality.

~ Reduction in the amount of waste going to urban areas and dumps, as we have seen the production of waste in many urban areas is high with this waste to energy technolgy large amount of wastes will be reduced.

~ It will also increase the revenue for the government from the sale of energy sources, including electricity, diesel, petrochemicals, gas for domestic use, and fertilizer as an agricultural input.

~It will create employment for many young people who are currently struggling to find work.

~ And also, the system will greatly help not to depend on rain as the main source of producing electricity.

To sum up, the continuous growth of technology is helping developing countries to learn from the developed economies, such as the countries of Europe, Asia, and the Americas, that use this waste-to-energy approach in generating energy that they use for various purposes.

Despite improved restructing of Waste collection system in some parts of the country, especially in large cities such as Dar es salaam, has a large collection of waste that is not used and is a big nuisance to the citizens. Through waste to energy technology, the government, in collaboration with TANESCO, NEMC, municipalities, and various environmental stakeholders, can jointly conduct research on these energy generation systems, their benefits and harms, as well as how much money can be invested in these systems. Through these systems, we will be able to eliminate the huge burden of electricity supply and waste generation and make the environment cleaner. Through these systems, we can be able to produce construction materials as well as tackle outbreaks of diseases such as malaria and cholera, youth unemployment, inflation in the availability of fuel for automobiles, and gas production.

TANZANIA TUITAKAYO is in need of solutions that not only ensures continuous energy provision for it’s citizen but also establishes an efficient waste management system that can foster the development of green cities for the coming decade.
