Papresa implement X-Trim to maximise performance

The Papresa Paper Mill in northern Spain produces newsprint paper and packaging paper from recycled paper. Papresa’s production capacity of 375,000 tons of paper is delivered by three paper machines and two de-inking plants. Following the company’s recent acquisition by Quantum Group and as part of the new owner’s industrial diversification plan – a response to the global decline in newsprint – the mill will now be producing new products such as containerboard. This strategy responds to the growing demand for packaging as a result of the growth in e-commerce.

Successful implementation of the new strategy was going to rely on the use of technology to automate processes and facilitate more effective forward-planning and decision making.  Most of the planning and trim processes were being carried out manually using Microsoft Excel and while this approach had been satisfactory for the production of a range of newspaper print reels, the company was about to invest in both new and existing equipment and wanted to maximise productivity.

The investment in new equipment would include increasing production capabilities with a full rebuild of one paper machine scheduled for spring 2022, and a new OCC plant to cover the requirements of raw material by the production increase. To accommodate the period of time when this machine was unavailable, and in advance of the completion of the rebuilding work, the factory needed to find ways to operate more efficiently in advance of work starting. Building automation to the planning processes was seen as a potential solution that would also be able to increase the visibility of future planning decisions.

Greycon Ltd proposed the opt-Studio and X-Trim solutions to Papresa to help meet their goals. The trim optimisation tool reduces waste and improves machine efficiency while reacting to customer requirements by prioritising urgent orders without missing deadlines for other production throughput. This is a combination of tools that automates production to optimise trim processes and consequently deliver much-improved dispatch times. The solution facilitates daily production planning while identifying any conflicts in production capacities and capabilities at the same time as providing the commercial and logistics department with information about production plans, order delays and any backlogs.

“opt-Studio has allowed us to transform our production planning system, reducing the workload by automating the optimisation of materials, reducing product in process, significantly reducing waste, and helping improve our competitiveness and profits,” states Miguel Ángel Sánchez García, Papresa CEO. “We are happy with the support and professionalism throughout the project, which was delivered within the time constraints that we set. We are looking forward to a fruitful partnership with Greycon as we continue to upgrade our technologies.”
