GreenBox™: Solar Cold Storage and AI-Powered Market Intelligence for Climate-Resilient Agriculture

Across the Republic of Congo and Central Africa, smallholder farmers and food traders face significant post-harvest losses due to limited cold-chain infrastructure, unreliable electricity, and weak access to market information. Perishable products are often sold immediately at low prices or lost before reaching consumers. GreenBox™ was created to address this challenge through decentralized solar-powered cold storage combined with thermal energy storage, IoT monitoring, and AI-supported digital tools. Its pay-as-you-store model makes cooling accessible without requiring farmers to purchase expensive infrastructure, while market and weather information helps users make better storage and selling decisions. The approach aims to strengthen farmer incomes, food security, and climate resilience.

Smallholder farmers, fishers, and food traders across Central Africa face high post-harvest losses because affordable and reliable cold-chain infrastructure is scarce. Unreliable electricity, limited storage capacity, and weak access to timely market information often force producers to sell perishable products immediately, even when prices are low, or risk losing them to spoilage. This reduces household incomes, wastes valuable food and resources, and increases vulnerability to climate and market disruptions. Women and youth in rural food value chains are particularly constrained by limited access to technology, finance, and productive assets. GreenBox™ addresses this gap by making clean, affordable cold storage and actionable market intelligence accessible through a pay-as-you-store model.

GreenBox™ aims to expand affordable access to renewable-energy-powered cold storage for underserved farmers, fishers, and food businesses; reduce post-harvest losses and food waste; increase users’ income by enabling better storage and selling decisions; strengthen climate resilience through clean cooling and digital intelligence; and create green livelihood opportunities for women and youth through local operation, technical services, and entrepreneurship.

GreenBox™ is a climate-tech company based in the Republic of Congo developing decentralized, solar-powered cold-chain infrastructure and digital tools for underserved agricultural communities. The company addresses post-harvest losses caused by limited cold storage, unreliable electricity, weak logistics, and insufficient access to timely market information.

GreenBox™ combines solar refrigeration, thermal energy storage, IoT monitoring, and AI-supported digital intelligence to help farmers, fishers, traders, and food businesses preserve perishable products, monitor storage conditions, and make better decisions about when and where to sell. Its cooling-as-a-service model enables users to access cold storage on a pay-as-you-store basis rather than purchasing expensive infrastructure.

By extending the usable life of perishable products, GreenBox™ can reduce spoilage by up to 90% for targeted products and help producers avoid distress sales when market prices are unfavorable. The digital layer can provide market-price, demand, and weather insights, while future integrations can improve access to financial services such as micro-insurance.

GreenBox™ also promotes inclusive green entrepreneurship by creating opportunities for women and youth to operate local cold-storage hubs, provide technical and logistics services, and participate in agricultural value chains.

The long-term goal is to build a distributed network of renewable-energy-powered cold-chain hubs across Central Africa, reducing food waste, strengthening farmer incomes and food security, creating green jobs, and reducing dependence on diesel-powered cooling and unreliable electricity.
