In Tamale, Northern Ghana, 25-year-old Hyginus Laari kept coming back to a problem he saw widespread in his community. Open defecation, instead of using toilets,听contributes to the spread of bacterial diseases such as cholera and diarrhea.
The tropical climate of Tamale makes its soil favorable for the cultivation of staple cereals, legumes and tubers, and听rice is a very popular food. But when milling rice, the husk on the outer part of the grain is often thrown away鈥攚asted.听听
Yet the husk has unique physical and chemical properties that are not being harnessed in Ghana and across many other African countries.听Laari鈥攁 regional finalist in the Young Champions of the Earth prize in 2018鈥攄ecided to change this, using waste rice to address the problem of open defecation. 听听
His idea is an eco-toilet, installed using boards made from rice husks. The husks are first dried and screened for particles of the right size. Then, they are blended and a special adhesive in liquid form is sprayed to make a sheet. The sheets are then compressed, heated, cooled, trimmed and sanded down.
The toilets are made using a granite flooring. A commode is then inserted and pipes leading toward a pit, and rice-husk panels are screwed into place to complete the walls around the toilets. Laari is now looking for funding to scale up his idea.
听鈥淚mproper waste management has serious health and environmental consequences. If it persists, it will undermine Africa鈥檚 efforts to achieve the Sustainable Development Goals,鈥澨鼳bdouraman Bary, 缅北禁地Environment Programme鈥檚 Chemicals, Waste and Air Quality Africa sub-programme coordinator, said.
Isaac Emmanuel, from Covestro, one of the world鈥檚 leading polymer manufacturers which drives the Young Champions of the Earth Prize, worked alongside Laari to help him develop his idea further.
鈥淚t was very fulfilling to interact with Hyginus and share in igniting new avenues for his idea,鈥� he said.听鈥淭hough the challenges are enormous, youth like him who are full of energy and hope keep up the positive spirit in all of us.鈥�
We caught up with Laari to ask him where it all started.
What inspired you to come up with the idea of making eco-toilets from rice waste?
Reading about India's household sanitation and the tremendous improvements made during the Swachh Bharat Mission,听to increase coverage of safe sanitation services in the country, have inspired me. Too often, the husks of rice鈥攁 major food in Ghana鈥攁re either burnt into ashes or dumped as solid waste. At the same time,听no district in Ghana has been certified as open-defecation-free. Despite education about its negative impacts on society, the practice of听open defecation remains a major challenge in Ghana.听Our eco-toilet innovation听creates a cleaner environment while also tackling rice husk waste.听It is installed using agro-waste board panels made from rice husk, that are low-cost and eco-sensitive for the construction industry.
What challenges have you faced along the way, and how have you overcome them?
Community sensitization and funding have been my major challenges. While at the University for Development Studies in the Northern Region of Ghana, I found writing blogs about the sanitation challenges in Ghana and sharing them on social media a very good way to raise awareness about my work in the initial phases.
Have you found being young in general a challenge in implementing your work?听
Not at all鈥攊n fact I have benefited since I have older people as mentors. As the late Kofi Annan once said: 鈥淚 talk to young people鈥攖heir attitude, determination to make a difference, innovative spirit and desire to change things gives me hope.鈥� Being young should never be an excuse not to find innovative ways to tackle sanitation. I think it is my responsibility to think beyond my age and create the clean Ghana for the next generation to inherit, that we can all be proud of.
You were shortlisted as a regional finalist for the Africa region in 2018. Has this helped you on your journey?
Since applying to be a Young Champion of the Earth, I have been selected among听the top 100 African landscape restoration youth leaders under the Youth in Landscape initiative for the African region prior to the Global Landscapes Forum in Nairobi. I also filmed a documentary on my project for national television. I participated in the Clean Ghana Challenge Competition and emerged as one of the winners, and my project continues to catch the attention of mentors who are willing to support me.
What is your vision for the future?听
My vision is to听install household eco-toilet facilities across communities in Ghana and Africa. And, to听create sanitation awareness across Ghana and Africa鈥攎ost recently through a mobile application. As听young people, we are the leaders of tomorrow. We must be on the front line of world development. My vision is to continue to reach out and inspire more young people to solve environmental problems, especially those addressed by the Sustainable Development Goals, contributing to the 2030 agenda.听
