Malinga turns waste to good use

40 AFRICAN INNOVATORS

IN 2015, Samuel Malinga, at the age of 26, founded Sanitation Africa – a company engaged in turning human waste into briquettes for cooking and agricultural manure. For his innovative approach to waste management, Samuel has been recognised by several organisations, including the Tony Elumelu Foundation, which awarded him a grant to expand his operations. In 2014, Ventures Africa, a business and lifestyle publication, listed him as one of the 40 African innovators to watch. While visiting the UN headquarters in New York recently, Samuel shared his experiences with Africa Renewal’s Kingsley Ighobor.

AFRICA RENEWAL: Why are you at the UN headquarters?

MALINGA:

I am here with 16 other young leaders from around the world to draft a one-year plan on how we can advocate for Sustainable Development Goals (SDGS) to ensure they are achieved by 2030.

Why were you selected for this trip?

I do sanitation projects, innovative toilet construction and upgrades. Our low-cost toilets address some of the challenges of climate change, such as soil collapse. Also, we have an innovative solution for emptying toilets, especially in the hard-to-reach areas due to poor infrastructure. It allows people to re-use their toilets in areas that don’t have much space, instead of digging new pits.

You said they are ‘low-cost’. How much does it cost?

For emptying a toilet, a client pays roughly $50 (R655). It costs between $200 and $400 to construct a new toilet. So it’s cheaper to empty old ones (when the pit gets full after several months of use, depending on the number of users) than to construct new toilets.

Describe briefly your innovative solution.

We are converting human waste into briquettes for cooking and manure. Our research has shown that our briquettes burn longer and are four times cheaper than firewood. We developed a pump to empty pits and then a treatment plant that turns the dried faecal sludge into briquettes that are used for cooking.

How many communities in Uganda are you operating in?

We are operating in three regions – greater Kampala, and in parts of eastern and western Uganda.

How many people do you employ?

There are six permanent employees, but we hire young people on a part-time basis to do marketing. Depending on tasks, we hire 10 to 20 more people for toilet construction.

Without your efforts, how would communities cope?

I think there would be a big problem because people dump their waste into draining channels, which end up in water reservoirs and supply systems. There would be a lot of contamination.

Who is financing your operations?

The first money I got was from the Future Project in Lagos, Nigeria, spearheaded by the Tony Elumelu Foundation. It gave me about 2 million naira ($11 000 in 2014), with which I set up my company’s structures.

But it’s a profitable business?

Yes.

Which means in the future you could survive on your own?

Yes, that is the ultimate goal. A 25% profit margin could make our operations sustainable.

How do you see your work within the global efforts to achieve SDGS?

We are going to do a lot of community mobilisation. We need to make sure everybody is involved, particularly the youth.

How would you describe the socio-economic conditions of young Ugandans?

Most, especially those who have formal education, expect to get jobs after school. But these jobs are not readily available. This is why many are now advocating their rights: they want to be involved in decision-making, policy and preparing budgets.

What other challenges do young people in Uganda face?

They lack financing to start businesses and are not properly represented politically.

Can you tell us who or what inspired you?

The community in which I grew up. At the age of 12, I saw people suffering from sanitation-related diseases such as cholera, diarrhoea and dysentery. So I went ahead to study engineering.

How do you see your business in five to 10 years’ time?

We want to reach fast-growing towns in Uganda, employ more young people, and reach other parts of east Africa.

How do you assess current youth policies in Uganda?

There are no clear policies and it’s one of the things I hope to advocate. – Africa Renewal
