Swiss Tech Cuts Africa Food Waste 30% After Harvest

Every day, two billion people eat foods made possible by technology developed in Switzerland, and now that same innovation is tackling food security across Southern Africa.

Bühler, a family-owned Swiss company with over 50 years in South Africa, is transforming how the region processes everything from wheat and maize to pasta and chocolate. Their technology cuts post-harvest losses by around 30% through advanced drying, cleaning, and color sorting that removes contaminated materials early in the production chain.

Marco Sutter, Managing Director of Bühler Southern Africa, says the secret is maximizing value from every kernel of grain. The company invests up to 6% of its revenue into research and development, keeping it at the cutting edge of food safety and efficiency.

Data and artificial intelligence are revolutionizing how milling plants operate across the continent. Large milling groups now compare energy use, yields, and efficiency across their global sites to benchmark performance and identify improvements.

AI is emerging as a powerful decision-support tool that helps operators make smarter choices based on real-time data. While it can't replace skilled workers, it helps them work more effectively and waste less.

The Ripple Effect

The impact extends far beyond individual factories. Bühler partners with universities, training institutes, and industry associations to build a stronger food processing ecosystem across Southern Africa.

With skilled workers in short supply globally, the company has made training a priority. Sutter points to Switzerland's apprenticeship model, where 70% of school leavers enter trades, as inspiration for developing Africa's next generation of food technologists.

The company translates sustainability from buzzword to reality through practical outcomes: higher yields, less waste, better quality, and lower water and power consumption. Advanced technology only delivers results when properly operated and maintained, making operator training just as important as the machines themselves.

Bühler's combination of Swiss engineering, local knowledge, and commitment to skills development is building more resilient food systems where they're needed most. The company will showcase its latest solutions at the IAOM Mideast and Africa Conference in Cape Town this November, the premier gathering for the region's milling and feed processing industry.
