X4LIME NEWS — Lime Production Experience continues at BERGMANN KALK

Implementing the Digital Life Cycle at Bergmann Kalk: A Shared Effort Toward Hydration Process Optimization

From connection to collaboration: how X4LIME and Bergmann Kalk brought new digital insight into lime hydration.

What did our team find?

At Bergmann Kalk, we identified the opportunity to extend the DIGITAL LIFE CYCLE — already successfully applied to the PFR lime kiln (QualiCal SYN 40, operational since 2016) — to the hydration process. The hydration system, also supplied by QualiCal and operational since 2021, had since become part of the ongoing X4LIME PRC Services.

This service connects, monitors, and analyzes operational data with the goal of optimizing plant performance — always in close coordination with the site team, supporting the everyday challenges of lime production.

Specifically, the hydration system lacked digital visibility into two critical product quality parameters: moisture and temperature at the outlet. Through active dialogue with the site’s process and maintenance teams, it became clear that introducing reliable instrumentation for monitoring these parameters would significantly enhance process control and troubleshooting capabilities

What was the trigger for this analysis?

The initiative was driven by Dirk Schönfelder, Bergmann Kalk’s Production Manager, who leveraged the ongoing PRC service agreement with X4LIME — renewed annually to ensure proactive remote support.

In early 2025, the CONNECT phase of the Digital Life Cycle was officially launched for the hydration process. Under Dirk’s coordination, the site team identified suitable sensor solutions for testing and integration.

From there, the X4LIME remote team — including Process Leads Edoardo Cella and Automation Engineers Davide Beretta — worked in tandem with Bergmann’s on-site electricians and operators to implement the new instrumentation. Data from the new sensors was made available both in the HMI SCADA system and on Mi-Live App, ensuring real-time access to quality trends to all the plant followers anytime, anywhere following the motto in the right time, right place and right hands.

What was the value to the customer?

The value of this collaboration lies in its daily operational impact. As shown in the early days, the new sensors immediately proved useful — helping identify anomalies such as moisture spikes correlated with temperature drops and water supply reaction. A clear example came when a sensor reading spiked due to residual material on the probe after shutdown. Thanks to the visibility via Mi-Live, the issue was identified and quickly resolved on-site.

🗣️ Quote from Dirk Schönfelder — Production Manager, Bergmann Kalk

“There is almost nothing better than progress!” “Thanks at all for that nice result and commitment! Danke für das tolle Ergebnis und das Engagement.”

🗣️ Quote from Waldemar Neumann — Site Operation Lead, Bergmann Kalk

“It’s very nice that it can be seen in the Mi-Live app!”

🗣️ Quote from Edoardo Cella — X4LIME Team Lead

“This is the essence of the Digital Life Cycle: connecting people and data to make improvements visible, actionable, and continuous — together.”

Digital Transformation for Sustainability

This project embodies Goal 9: Industry, Innovation, and Infrastructure of the UN Sustainable Development Goals. By leveraging smart sensors, cloud apps, and a structured remote collaboration model, we help traditional industries like lime production become more data-driven, efficient, and resilient.

Lime Industry Digitalization

From sustainable fuels to integrated execution — a real case of innovation in the lime industry

In early 2025, X4LIME was entrusted with the supervision and integration of a new biomass fuel firing system at the KLK plant in Meissner, Germany.

The Context

A shared pathway toward digital sustainability

In line with the EULA 2025 Pathway, this project embodies the ambition to make digitalization the baseline for every lime operation. As emphasized by EULA, digital tools are no longer optional, but a minimum common denominator to achieve the sector’s climate and efficiency goals. From intelligent combustion control to predictive maintenance, the integration of technologies across partners in this project contributes directly to that vision — enabling measurable decarbonization, better resource management, and a smarter lime industry.

The project involved integrating Carbotechnik’s dosing technology, upgrading blower management via AERZEN’s LBC module, and aligning these systems within the existing PLC/HMI infrastructure originally designed for lignite-based combustion.

The Challenge

One of the most pressing challenges was the need to manage this complex transition with minimal on-site presence, maintaining high standards of activities m quality while containing operational costs for the customer.

X4L’s Digital Approach

Thanks to its digital-first attitude and engineering flexibility, X4LIME — in co-operation with SYSWARE — successfully implemented a remote-driven commissioning strategy, supported by structured online collaboration with the client and partner companies.

Over a 4-week period, the commissioning effort included:

• Comprehensive I/O checks and validation: ensuring all field signals, sensors, and actuators were correctly mapped and functional in coordination with the customer’s electricians.
• PLC/HMI tuning and configuration: adapting logic and HMI interfaces for full integration of the new biomass dosing and blower control systems.
• Supervision of functional cold tests: remote observation and guidance through the step-by-step validation of the process, preparing the system for safe hot commissioning.
• Live assistance during hot start-up and tuning: real-time support during system ignition and optimization of combustion parameters in wood dust mode.

Out of the entire commissioning period, only one week involved physical presence on site, while all other tasks were completed through remote sessions, live supervision, and efficient collaboration.

The Goal

This hybrid model allowed for a cost reduction of over 40% compared to a traditional on-site commissioning strategy, without compromising on technical depth or responsiveness.

World Biodiversity Day

Today, on World Biodiversity Day, we celebrate the unique contributions of our Bamboo4LIME initiative to the environment.

The Bamboo4LIME innovative project, a collaboration between X4LIME and Forever Bambù, underscores the essential role of bamboo cultivation in promoting biodiversity and achieving carbon neutrality in the lime industry.

The Role of Bamboo in Biodiversity

Bamboo is a remarkable plant that grows rapidly and requires minimal intervention. It is known for its exceptional ability to absorb carbon dioxide, making it a powerful ally in the fight against climate change. Moreover, bamboo plantations provide a habitat for a variety of species, enhancing the ecological value of previously degraded lands. This aligns perfectly with the principles of biodynamic agriculture practiced by Forever Bambù, which emphasizes soil health and biodiversity .

Forever Bambù’s Commitment to Biodynamic Agriculture

Forever Bambù utilizes biodynamic practices that foster a thriving ecosystem. Their approach includes using composted manure, promoting earthworm activity, and hosting beehives not for production, but to support the local ecosystem. These methods enhance soil fertility and vitality naturally, ensuring that plants are nourished by a healthy soil ecosystem .

Bamboo4LIME: A Step Towards Carbon Neutrality in lime industry

In partnership with CO2 net zero, Bamboo4LIME aims to reduce the carbon footprint of lime production significantly. Bamboo’s fast growth and high carbon sequestration capacity make it an ideal raw material for creating carbon credits. By integrating bamboo into the lime production process, we are able to offset emissions and move towards a more sustainable industry .

BAMBOO4LIME — a partnership between ForeverBamboo and X4LIME generating Carbon credits for Lime…

Bamboo’s Broad Environmental Impact

The environmental benefits of bamboo extend beyond carbon sequestration. Bamboo plantations help in restoring degraded lands and preventing soil erosion. The diverse flora and fauna that thrive in these plantations contribute to a balanced ecosystem, promoting overall biodiversity. This makes bamboo a key player in both ecological conservation and sustainable industrial practices .

Merging Industry and Ecology

Through the Bamboo4LIME initiative, X4LIME is not only committed to achieving carbon neutrality but also to enhancing biodiversity. By transforming abandoned and degraded lands into thriving bamboo plantations, we contribute to ecological restoration while supporting sustainable industrial processes.
