Unilever GlobalChange location
Unilever’s site in Mannheim, Germany, began life as a soap production factory in 1899. Today, it’s home to a world-class manufacturing facility for our Dove Bars and a highly advanced distribution centre for our Home Care, Personal Care and Beauty and Wellbeing products in Germany.
It’s an example of how we’re continually investing in the latest technology and skills to ensure we meet the evolving needs of our customers and consumers, and drive sustainable business growth.
“This global powerhouse is setting the pace for operational excellence,” says Factory Director Silvia Rissel. “By deploying cutting-edge technologies, we’re continually improving productivity and efficiency. We’re able to respond to shifts in customer and consumer demand, equip our workforce with digital skills and limit our impact on the environment.”
The manufacturing site at Mannheim is part of a network of four sites that supply Dove Bars to customers all over the world. These sites share data in real-time through digital twin technology, enabling us to build a smarter, faster and more efficient global operation.
While the Mannheim Dove Bar process has always operated 24/7, through automation and digitisation, the factory team has become increasingly leaner and more efficient. Digitisation is also enabling us to continually improve OEE (overall equipment effectiveness) – a measure of manufacturing productivity and efficiency.
For example, we use digital technology to count the number of Dove bars on the production line and compare this with the number of boxes feeding into the packaging lines. Before the stock on the line runs out, it automatically calls for more packaging to be brought to the line. As well as being highly efficient, this ensures accurate tracking and management of stock.
We recently made significant investments in the factory’s production lines to expand capabilities and support future growth, and in on-site solar power to improve energy efficiency. We also redesigned our packing lines to supply Dove Bars in 100% paper packaging, saving around 500 tons of plastic every year.
The factory pioneers programmes to ensure that every Dove Bar produced across the world is of consistently superior quality. For instance, we’ve been piloting AI-enabled cameras to automate quality checks. These are capable of inspecting 800 bars per minute – faster than our current high-speed production lines – and will go into operation later this year.
“We believe in crafting unmissably superior products, and our Dove Beauty Bar is a great example,” says Marcela Melero, Chief Growth Officer for Dove Personal Care, North America & Dove Masterbrand. “While ordinary soaps can strip skin of essential moisture, Beauty Bars contain moisturising cream to hydrate the skin alongside mild cleansers to wash away dirt and germs.”
“Our production sites are essential in creating these iconic bars and ensuring we get them into the hands of consumers in more than 180 countries around the world.”
Our Mannheim site is also home to one of Unilever’s largest distribution centres. What started out as a small storage facility was rebuilt in 1999, and now houses a cutting-edge warehouse management system that automatically manages and tracks all materials, with minimal operator input.
With a storage capacity of over 36,000 pallets, the centre delivers finished goods from 30 plants across Europe. At full capacity, it’s capable of picking 4 million cases (24 million units) and shipping 320,000 pallets (over 60 million units) a year.
Importantly, with a 99.8% ‘customer case fill on time’ (CCFOT) rate, the centre is vital to ensuring in-store product availability, which in turn is instrumental in driving growth for Unilever.
The industry standard for CCFOT in logistics can vary, but a common benchmark is around 95%. This metric measures the reliability of delivering the correct quantity of products to customers within the agreed timeframe. Achieving high CCFOT rates is crucial to delivering to consumers the products they want, when they want them.
While the distribution centre can already respond quickly to peaks in customer orders, we’re currently investing in a ‘layer picking’ operation so we can react even faster. This is about using automation to pick full layers of products from pallets instead of individual cases or units. Due to be fully operational in 2026, this will increase picking capacity by 50% during peak seasons and generate yearly savings of over €1 million.
“We’re accelerating digitisation and new technologies across our operations to enhance productivity and deliver products quicker, with the same unmissable quality that our consumers have come to trust,” says Silvia. “With initiatives like plastic-free products, solar energy and apprenticeships fostering young local talent, there’s a bright future for our manufacturing site at Mannheim.”
The World Economic Forum has recognised Unilever’s Beauty & Wellbeing factory in Tinsukia, India, as an End-to-End Value Chain Lighthouse site. Here’s how the plant has scaled up AI to work faster, smarter and more sustainably.
Amazon is one of Unilever’s most valued e-commerce retailers. We’ve been working together to ensure our supply chain is as seamless as possible – a move that’s better for both businesses.
