Product Recovery (Pigging) Case Study on mondelez
How an HPS Pigging System Improves the Efficiency of Chocolate Processing and Production.
- Mondelēz International, Inc. (Nasdaq: MDLZ) empowers people to snack right in over 150 countries around the world.
- The company is a long-standing customer of HPS and is already benefiting from multiple HPS pigging systems.
- Mondelēz approached HPS to incorporate liquid product recovery (pigging) technology in a new shared pipeline at the Mondelēz, Svoge chocolate manufacturing facility in Bulgaria.
- The key objective was to remove and recover all traces of the previous product quickly, efficiently, and effectively from the shared pipeline.
- HPS designed, supplied, and implemented a fully automatic pigging system.
- By recovering up to 99.5% of product from pipelines, pigging increases product yields and capacity, enables shared instead of dedicated pipelines, and reduces waste.
- If the company wasn’t pigging, they would spend large amounts of time, resources, and labour on cleaning the pipelines when changing from one product to another.
- The system is fully automated which means it increases operational efficiency, enhances safety, and minimises the risks of human error by reducing manual intervention.
About Mondelēz International
Mondelēz International, Inc. (Nasdaq: MDLZ) empowers people to snack right in over 150 countries around the world.
With 2021 net revenues of approximately $29 billion, MDLZ is leading the future of snacking with iconic global and local brands such as Oreo, belVita and LU biscuits; Cadbury Dairy Milk, Milka and Toblerone chocolate; Sour Patch Kids candy and Trident gum. Mondelēz International is a proud member of the Standard and Poor’s 500, Nasdaq 100 and Dow Jones Sustainability Index.
The Mondelēz Svoge plant is one of the biggest and most modern chocolate manufacturing sites in Bulgaria. Not only is the manufacturing facility the birthplace of Milka Peanut Caramel, it also produces a wide range of global and local brands. This includes Cadbury, Alpen Gold, Lacta, Moreni, Svoge and Sezoni.
Mondelēz Svoge produces a wide range of chocolate products.
They are a long-standing customer of HPS, and have multiple HPS pigging systems in their production plant. During their recent project, Mondelēz approached HPS to discuss implementing an additional pigging system to clean the pipelines when switching from one product to another.
Mondelēz wanted to use a shared pipeline for different formulations of product, so it was important to quickly, efficiently, and effectively remove all traces of the previous product.
By recovering as much useable product as possible, not only does pigging effectively clean chocolate pipelines, but it increases yields and reduces waste.
Krasimir Dimitrov at Mondelēz, Svoge, commented,
“The idea for a pigging solution came from a project where we wanted to implement different flavours for our product”
“In that matter we had one pipe which we wanted to use for two different types of products. And when we were switching between the two products, we needed to make sure that everything is clean such as vessels, pipes and equipment”
Why Mondelēz Chose HPS as their Pigging Systems Provider
HPS has a solid reputation as the world’s leading hygienic and sanitary pigging systems specialists. That’s because HPS has a proven track record of successful projects which deliver high return on investment (ROI), rapid payback, and that exceed client’s expectations.
In addition, HPS has specialised in process pigging since 1995 and has worked with a wide variety of companies that manufacture chocolate, candy, confectionery, and similar type products. This includes a number of Mondelēz plants around the world.
There are certain considerations that need taking in to account when processing and pigging chocolate products. HPS has extensive experience in pigging systems for chocolate processing and production. This experience meant that, as well as being fully aware of the chocolate production process, HPS experts were able to recommend a highly effective, and efficient pigging solution to meet Mondelēz’s needs and requirements.
Asked why Mondelēz chose HPS, Krasimir commented,
“We have worked with HPS for many years. HPS is an approved supplier for Mondelēz, and we’ve had a positive experience with the products which HPS provide for us”
“HPS can offer us everything that is needed for a pigging system”
Working closely with Mondelēz, HPS designed and supplied a single-pig pigging system for use with chocolate and chocolate-based products.
The pigging system recovers up to 99.5% of product from the pipeline. If it wasn’t for pigging, this residual product would be wasted. It would also be much more difficult to use the line for more than one type of product.
HPS engineers and pigging system designers recommended all the equipment required to launch, receive, and return the pig to and from source and destination. This includes the pig launcher and receiver station, and the pneumatics and air sets to propel the pig using filtered air.
It also includes a bi-directional fully detectable food-grade pipeline pig as well as AccuTect pig detectors to enable safe, reliable, and accurate pig detection and PLC control.
The solution includes several types of valves. Where required these are jacketed and have visual sensor position indicators.

The primary aims of the project were to use the pigging system to clean the chocolate pipelines when switching from one product to another, enabling Mondelez to use the line for multi-products.
The HPS pigging system recovers up to 99.5% of product from the pipeline. If it wasn’t for pigging, this product would be wasted during the cleaning and changeover process.
Because the pigging system reclaims nearly all residual product from the pipe, Mondelez can use the same pipeline for different flavours and configurations of product.
So, not only does pigging increase yields and reduces waste, but it increases the capacity and flexibility of their operations and speeds up changeover times.
It also saves considerable amounts of time, resources, and labour on cleaning vessels, pipes, and equipment.
That’s because there is less product to remove which reduces the effort and resources needed to clean process piping.
In addition to the above benefits, by saving energy and resources, pigging has also helped Mondelez improve its environmental sustainability.
When asked if he would recommend HPS to other companies, Krasimir replied:
“Yes, because the project went very well, and the equipment is very sustainable”.
Mondelez is a long-standing customer of HPS Product Recovery Solutions, and they have multiple HPS pigging systems in operation in the Svoge plant.
As the demand for their products continues to increase, and their production expands, we expect to see even more pigging solutions in their manufacturing plant.
When asked about Mondelez’s plans for expansions or additions for pigging systems in the future, Krasimir commented:
“It will be better to have more solutions in our plant like this one we implemented.”
