An innovative long lasting mosquito repellent textile to protect against malaria transmission.

We manufacture a long lasting mosquito repellent yarn that can be used to make protective clothing for people in malaria endemic areas.

Problem: What problem is this initiative trying to address?

Malaria is a parasitic disease that infects 200 million people world-wide every year and results in about 600000 deaths. 90% of all malaria deaths occur in sub-Saharan Africa especially in rural areas. 75% of these deaths occur in children under the age of 5 and the rest of the victims are mostly pregnant women. The main reason why malaria is still a problem is because of outdoor mosquito bites. Rural productivity is affected affected by the spreading of malaria due to morbidity and mortality caused by malaria.

Solution Summary: What is the proposed solution? What do you see as its most promising aspects for creating shared value?

The proposed solution is based on a long lasting insect repellent textile that can be used to manufacture repellent outdoor consumer apparel. The textile is first manufactured by spinning our innovative proprietary yarn designed to store and slowly release volatile insect repellents over an extended period. In the final manufacturing process, this yarn is co-knitted with cotton to produce a high quality, comfortable and robust long lasting repellent textile. The textile can be cold washed up to 25 times or kept under room conditions for up to 4 months and still repel insects such as mosquitoes effectively.

Impact: What is the impact of the work to date? Specify both the social and the environmental impact of your work

In December 2017, we intend to run a crowd funding campaign for our social enterprise with the intention of assisting people in resource limited communities in Mozambique where malaria is mostly endemic. In this campaign, for every 1 unit purchased by consumers, AAC will donate a unit as mosquito repellent school socks to children in resource limited malaria endemic areas. . We will be donating socks because according to a study done at the University of Pretoria, 93 % of bites from malaria transmitting mosquitoes occur on the lower limbs. This field trial will then help us to generate valuable information on the effectiveness of our technology in preventing outdoor malaria transmission.  

Financial sustainability plan: How is this initiative financially supported? How will you ensure its financial sustainability long-term?

The initiative is currently being sponsored by Grants we won from the SAB Foundation Social Innovation Awards and the Gauteng Accelerator Programme Biosciences award. We also have seed fund from the Technology Innovation Agency in South Africa. At the moment 100 % of our annual budget comes from Grants. With time we will earn income from selling our mosquito repellent apparel to outdoor enthusiasts and this will help subsidize the insect repellent products for people in resource limited communities.

Unique value proposition: What makes your initiative innovative? How does your project differ from other organizations working in the same field?

Our proprietary technology is a breakthrough in the manufacture of smart textiles that utilise alternative volatile liquid insect repellents. The advantage of these repellents is that there are virtually no reports of resistance from mosquitoes to the repellents we use. Another important aspect of liquid repellents is that they are non-lethal to insects. They therefore will not kill insects that may be important to the ecosystem unlike the insecticides that are used by our competitors.

Founding story: Share a story about the "Aha!" moment that sparked the beginning of this initiative.

The co-founders, Mthokozisi Sibanda, Kim Blakey and Tatenda Madzorera are researchers and fellow collegues who met at the University of Pretoria Institute for Sustainable Malaria Control who are. Mthokozisi developed our proprietary technology as part of his PhD studies. When he successfully developed the first set of prototypes of long lasting mosquito repellent socks, he immediately contacted Kim and Tatenda to immediately share this development and explore the prospects of forming a social enterprise. This was inspired by the fact that the raw materials required to make the prototypes were relatively inexpensive and hence the final products would be affordable for people in resource limited areas that are malaria endemic.
