Have you followed the news about Zanzibar Runs Tender for 18 MW of Solar these days? Tanzania’s Zanzibar, Kisap and Morogoro regions are areas where solar installations are concentrated. According to the International Renewable Energy Agency (IRENA), Tanzania had 16 MW of cumulative installed solar capacity at the end of 2023.

Tanzania installs a large number of photovoltaic panels

As the solar infrastructure in Tanzania expanding, the volume of aging PV panels will increase substantially in the coming years. Currently, with the growing number of solar installations reaching their typical lifespan of 25 līdz 30 years, the issue of proper disposal and recycling of these panels becomes crucial. The materials within the solar panels, such as silicon, silver, alumīnijs, and glass, hold great value and potential for reuse. Recycling these materials mitigates e-waste disposal’s environmental impact and brings profits to solar panel recyclers.

Essential Equipment for Solar Panel Recycling in Tanzania

Shredding Machines

Shredding is the first step in the recycling process. For Tanzania, a robust and cost – effective shredding machine is essential. A mid – sized shredding machine, capable of handling a moderate volume of solar panels, would be suitable. These machines are designed to break down the solar panels into smaller pieces, making it easier to separate the different materials. Given the country’s limited space and resources in some recycling facilities, a compact yet powerful shredder would be ideal. For example, a two – shaft shredder with adjustable cutting teeth can be used to handle the tough outer casing of the solar panels, as well as the glass and other components. It can operate at a relatively low speed to ensure energy efficiency, which is crucial considering Tanzania’s energy situation.

After shredding, magnetic separation equipment is necessary to extract the metallic components. Solar panels contain aluminum frames and some internal wiring with metal elements. A simple yet effective magnetic separator can be installed in the recycling line. In Tanzania, where cost – effectiveness is key, a belt – type magnetic separator can be used. This type of separator can be easily integrated into the existing recycling process. It works by passing the shredded material over a magnetic belt, which attracts and separates the magnetic materials, such as steel and iron – containing components. This equipment is relatively inexpensive to operate and maintain, making it suitable for the local recycling industry.

Thermal Treatment Furnaces

Thermal treatment is crucial for separating valuable materials like silicon and silver. In Tanzania, a basic pyrolysis furnace can be set up. These furnaces are designed to heat the shredded solar panel materials to high temperatures. At these temperatures, different materials can be vaporized or melted at different rates, allowing for separation. For instance, a batch – type thermal treatment furnace can be used. It can be programmed to heat the materials in a controlled manner, ensuring the efficient extraction of silicon and silver.

The Way Forward for Solar Panel Recycling in Tanzania

Investing in good-quality PV panel recycling equipment is just the first step. You’d better build a skilled worker team to run these recycling machines. Plus, the government has a big part to play. They can offer perks like tax cuts and subsidies to recycling businesses. This will help the solar panel recycling industry grow. It also means Tanzania can reuse valuable stuff from old panels, import fewer new materials, and cut down on e-waste pollution for a greener future.

With the right approach, equipment, and support, Tanzania can effectively address the issue of solar panel recycling and turn it into a profitable and sustainable business venture.
