SHIFT IN REFRIGERANTS
He notes that notwithstanding the global push towards natural refrigerants like
CO 2
, the adoption rate varies across different regions and supermarket chains . Additionally , regulatory hurdles and safety considerations surrounding flammable refrigerants like R290 pose challenges to widespread adoption , despite their environmental benefits .
As the industry moves away from hydrofluorocarbons ( HFCs ) towards natural refrigerants , challenges arise in navigating safety concerns and regulatory frameworks . The transition to low-GWP ( Global Warming Potential ) alternatives presents both opportunities and complexities , particularly in ensuring compliance with evolving regulations and addressing safety considerations . While Europe leads the way in adopting sustainable refrigeration practices , other regions , including Africa and America , are more gradually embracing these innovations . However , significant

disparities persist , with many supermarkets still reliant on traditional refrigerants .
“ With regulations prohibiting the release of refrigerants into the atmosphere , the industry is shifting towards more sustainable practices , including the recovery and reuse of gases . While some companies offer services to evacuate and recover refrigerants , the focus is increasingly on adopting natural refrigerants like CO 2
, which eliminate the need for evacuation and pose fewer environmental risks .”
In South Africa , regulatory frameworks regarding refrigeration standards and environmental sustainability are still evolving . While international agreements like the Kigali Amendment signal a global commitment to phasing out harmful refrigerants , implementation and enforcement vary across regions . While South Africa is a signatory , Howitt notes the absence of stringent local regulations compared to Europe , where compliance is more rigorously enforced . Despite efforts to raise awareness through workshops and

conferences , regulatory deadlines remain ambiguous , reflecting a slower pace of change in the African market .
“ However , the long-term benefits of natural refrigerants like CO 2
, including lower maintenance costs and reduced environmental impact , make them increasingly attractive despite the initial capital investment .”
He highlights the importance of considering lifecycle costs over upfront investments , particularly for large retailing groups . “ While upfront capital expenditure may be higher for eco-friendly refrigeration solutions , the lower maintenance costs and enhanced sustainability align with the companies ' environmental commitments and long-term objectives . Moreover , the push towards carbon neutrality and sustainability goals further incentivises investment in green technologies , driving demand for energy-efficient and environmentally friendly refrigeration systems .”
Beyond regulatory compliance and cost considerations , there is a broader cultural shift towards quality control and food preservation . “ By maintaining consistent temperatures throughout the supply chain — from manufacturing to distribution to retail — companies can enhance food quality and reduce waste . This holistic approach underscores the importance of temperature control as a critical factor in ensuring product integrity and consumer satisfaction .”
While regulatory challenges and market dynamics present obstacles to widespread adoption of eco-friendly refrigeration solutions , there ' s a clear momentum towards sustainability and environmental responsibility . By addressing regulatory uncertainties , promoting technological innovation , and aligning incentives with longterm sustainability goals , the refrigeration industry can pave the way for a greener , more efficient future .
