Setting up a conservation centre

As an all-in solution provider for mass paper conservation and mass storage GSK offers a complete range of industry standard holdings conservation services to archives and libraries in Germany – from mechanical and manual conservation and decontamination all the way to creating secondary copies and their hybrids. To ensure that opportunities for conserving holdings and the latest technological developments can be utilised outside Germany as well, we offer a service for setting up GSK certified conservation centres to qualified partner organisations. Gain the benefit of our technical expertise and experience and set up a centre for conservation of your holdings at your local site – tailored to meet your specific requirements.


Overview of our service portfolio:

Single-sheet deacidification – the Bückeburg Conservation Process (BCP)

  • Compact units

    Compact mobile deacidification units with a throughput of approx. 400 A4 sheets an hour. This is equal to an annual output of 700,000 A4 sheets in single-shift operation (8 hours) on 221 working days. This unit is also able to process oversize/broadsheet paper formats.

  • Large treatment units

    Large units can process up to 1,000 A4 sheets per hour, the equivalent of 1.7 million A4 sheets a year.

Both units can be tailored to specific requirements with regard to throughput and space requirements. According to number of staff and need, the performance ratings can be doubled or tripled by working in shifts.

  • Workstations for manual deacidification
    Setting up workstations for manual deacidification of severely damaged or fragile materials which cannot be processed mechanically.

  • Foliation devices
    Peripheral devices for preparatory mechanical foliation of individual sheets with a rate of up to 600 foliations an hour. Foliation guarantees the correct sequencing of individual sheets in the workflow as well as in subsequent use in archives.

  • Flattening devices
    Flattening devices for A4 and A3 formats for gently reducing the increased paper volume caused by the aqueous treatment process.

  • Laboratory equipment
    Small-scale laboratory equipment for regular daily testing of treatment success (pH value, alkaline reserve, tensile strength).

In addition, we also offer staff training and technical equipment maintenance to ensure smooth work processes and successful treatment results.

Regardless of the level of acidification prior to treatment, we guarantee a pH value between 8.3 and 9.0 for all documents after single-sheet deacidification using the book conservation process, as well as an alkaline reserve (calcium carbonate) of between 1 and 2 percent. These values correspond to those for new alkaline papers. In addition, for approximately 90 percent of papers we guarantee at least 30 percent greater strength (tensile strength after folding) as well as enhanced flexibility of the papers.

Book deacidification using the book conservation process

Our innovative book deacidification unit BoCo1 allows on-site processing of bound materials and books which do not allow single-sheet treatment. The configuration of the BoCo1 unit with the greatest capacity is able to treat up to 140 kg of bound material per work operation. In addition to deacidification, this unit offers integrated cleaning and removal of mould from materials and consolidation similar to the single-sheet process, depending on what material is actually being treated.


Long-term preservation of holdings using microfilm technology can be seamlessly integrated into the workflow of single-sheet or book deacidification. Microfilming is carried out according to DIN ISO 6199 and, depending on film quality, allows between 600 and 2,250 images per A4 microform. We equip your conservation centre with the required cameras and readers, and, upon request, install the latest microfilm scanning technology.


In the archive world too, digitisation has become an acknowledged medium for using and protecting valuable originals. We provide modern scanning technology using incident light, guaranteeing that processing is gentle. Just as with the digitisation of analogue microfilms, digital data too can be output to microfilm for long-term preservation.

In the case of both microfilm technology and scanning technology, we work with well-known international manufacturers and service providers, so that servicing and maintenance can be guaranteed worldwide.

We would be happy to advise you in developing your preservation holdings concept and to work with you in setting up a conservation centre tailored to meet your needs. As a certified partner you will not only be provided with technological expertise, but also receive tailor-made work process and workflow advice and continuously benefit from the advances we make in technology.
