Challenges we resolve
An Africa-wide problem
Energy access – electrification for all
- 600 million people (43% of the population of Africa) today have no reliable access to electricity.
- Conventional renewable sources of energy – solar, wind, geothermal – will not be the whole answer.
- With Africa’s agricultural economy being so important, there is an abundant potential power source in agricultural loss and waste.
- Today, Africa loses 1.3 billion tons of food every year in post harvest losses, at a cost of over $1 trillion.
- AW2E turns this loss into an energy gain, by generating biogas from the agricultural and market waste
- By using biogas, generated locally where the power is needed, we can provide abundant power to service local needs.
- Not only are we replacing fossil fuels, but we are avoiding the wasteful generation of Greenhouse Gases from the rotting vegetable and animal waste.
- Methane from rotting waste is 80 times more harmful than CO2 in the atmosphere.
The Cold Crunch
- Today, energy-efficient cold chains for perishable food and medicines in sub-Saharan Africa (SSA) are a vital but unaffordable luxury for most people.
- Food loss in supply chains runs at up to 60%, depressing farmers’ incomes, leading to vastly inefficient use of resources, and producing enormous amounts of greenhouse gases.
- Access to cooling is critical to achievement of the UN Sustainable Development Goals, because its absence affects the economy, social life and the climate.
- With access to power through biogas from waste, we can make cooling and refrigeration affordable and accessible where needed.
- With AW2E partner Zero2Cool’s cooling technology, most cooling will be free at the point of use.
Energy Challenges - Nigeria
- No, or unreliable, electricity supply, especially in rural areas; reliance on diesel generators
- Unaffordability of generator power (diesel price)
- Limited suitability of solar and wind in deployment of distributed power (microgrids)
- Critical services – power for food processing, cooling, refrigeration, hot water – are out of reach for most
- Leading to
- High food loss due to lack of refrigeration and temperature management
- Missing out on value-added food processing (export markets; unnecessary imports of food substitutes)
- Inability to manage supply and demand (higher seasonal price variations; food shortages)
- Food markets failing to maximise storage capacity (failure to serve market need; very high food losses)
- Overall, lower prices and lower quality food products, plus food shortages
- Increased transportation, fertilizer and water costs due to need to replace food lost
- Inefficient use, and long term degradation, of productive land
- These challenges are repeated across much of Sub-Saharan Africa.

Economic benefits and impact
Biogas System
- Low CAPEX
- Payback period: ~ 1 year
- Zero Carbon electricity for free
- Zero Carbon cooling & hot water for free
- Eliminating reliance on diesel & other fossil fuels
Diverse Revenue Streams
- PAYGO cold room (markets)
- 2-4 X storage capacity increase (increase in storage revenues)
- Reduce losses for market customers; storage as “pay-on-results”
- Bottled biogas/local electrcicity sales
- Liquid fertilizer sales/chemical fertilizer substitution (from digestate after anaerobic digestion process)
Impact
- Food loss reduction & fuel switch = significant GHG reductions
- Food loss reduction = $ impact from more stock to sell (straight to bottom line in food chain)
- Reducing dependance on imported fossil fuels
- Increasing opportunities for higher value export crops & products through access to power & cooling
- Reducing habitat use (and loss) through over cultivation
- Reducing food imports
