NanoFreeze – REDDI

Investing in Impact

P4G has awarded the partnership with about US $282,000 in grant funding. 

The NanoFreeze – REDDI partnership is scaling NanoFreeze’s innovative Cold Coats solution to transform refrigeration access in rural areas of Colombia. The initiative addresses critical gaps in cold chain infrastructure and energy access, helping farmers reduce food waste and enhance the competitiveness of Colombian agricultural exports. 

NanoFreeze is a bio-nanotechnology startup dedicated to transforming refrigeration by reducing food waste, optimizing energy efficiency and lowering CO₂ emissions. The company is 65% women-led, with all founders being women, aligning with the 2X Global Challenge criteria on gender equity and empowerment. 

Its product suite includes Cold Coats, Ice Packs, Coolers and Natural Freezers, all designed to replace traditional cold storage systems with sustainable alternatives. The patented technology, built on a novel bio-nanotechnology, improves the heating capacity of water-based coolants, allowing it to maintain stable temperatures for up to eight days without the need for plugged in refrigeration. Cold Coats are modular coolant packs that are designed to adapt to different product and packaging needs. The technologies prioritize resource efficiency, carbon reduction and accessibility for rural farmers, while also creating employment opportunities in underserved regions. 

To date, NanoFreeze’s Cold Coats have prevented over $764,000 in food waste for Colombian exporters, cutting spoilage rates from 30% to zero. Additionally, the Natural Freezers have demonstrated significant potential in commercial refrigeration. Pilots with industry leaders such as AB InBev and Postobón showed reductions of up to 44% in energy use, 5.03 tons in CO₂ emissions and US $6,600 in electricity costs within four months. These results highlight the scalability of NanoFreeze’s technology beyond agriculture, with applications across beverage, retail and logistics industries. 

During the partnership period, NanoFreeze seeks to scale Cold Coats and Natural Freezers in Colombia and internationally, shorten sales cycles from four to one month and invest in digital tools to measure food waste reduction, cost savings in energy consumption and CO₂ impact. 

REDDI, a leading technology and innovation development agency dedicated to transforming scientific research into successful business models, will provide expertise in leadership mentoring, technology validation and regulatory navigation. It also facilitates carbon credit certification and impact measurement, enabling NanoFreeze to monetize avoided emissions and attract ESG-focused investors. 

The partnership will also provide education and training and participate in export events to address limited cold chain awareness. NanoFreeze seeks to raise US $6 million for operations and R&D, laying the foundation for a Series A round to attract further investment. 

The partnership comprises the following partners: NanoFreeze (lead business partner); REDDI (lead administrative partner).
