Solar solution mooted for Africa's produce wastage problem
4 November 2015
In developing countries, particularly in the warmer climates of Africa and Asia,
45% of food goes bad because of a lack of cold storage. It's a specifically tough
challenge for small-scale farmers transporting fresh produce from rural farms to
urban markets. Food can be left in scorching heat for hours, ruining it and
ultimately leading to large financial losses for both farmers and sellers.
An industrial start-up company in Lagos, Nigeria, has developed a solution:
solar-powered refrigeration stations.
ColdHubs, founded by entrepreneur-farmer Nnaemeka Ikegwuonu, could have
the potential to solve the food wastage issue and help to save the livelihoods of the
over 500 million farmers in Africa, Asia and Latin America.
The idea has the potential to level the playing fields for small-scale
farmers
against large mass-production farming, giving them a competitive edge by solving
storage challenges. For South Africa, the ColdHubs idea could help fulfil some of the
goals of the National Development Programme, including sustaining rural
communities' economy and contributing to food security.
Using solar panels to power the refrigeration, ColdHubs is an easily assembled,
modular walk-in cold room that provides effective storage and preservation for
perishable foods for up to 21 days, cutting down on food wastage by 80%. Farmers
can rent the units as a pay-as-you-store subscription, making it cheaper to use.
Designed for use in small-scale fresh food production and at informal food
markets, ColdHubs' units provide farmers with 12cm-thick cold insulation walls,
keeping the inside temperature at a constant 5 degrees Celsius.
Chosen by the science ministries of United Nations member states, the
ColdHubs concept is one of 14 environmentally
friendly innovations from over 800
global ideas that best represent the UN's 2030 Sustainable Development Goals.
