- Batch recipe and glass chemistry optimisation studies using lab tests. Melting and dissolution processes of different batches were analysed. These tests proved to be very useful comparing the melting and fining efficiency of different batches, testing or verifying the benefits of using one raw material compared to another and/or analysing or verifying the benefits of new raw materials introductions. Our melting test procedures enables to determine the intermediate crystalline phase steps of the glass melting process and to determine the velocity of the dissolution and glass melt generation process. - Picture

- For both glass recycling companies and glass manufacturers using high cullet ratio batches, it is extremely important to have an excellent accurate and precise cullet quality control procedure. Using our unique in-house developed statistical calculation program, we give you a clear insight in the risk percentage to accept a non-conform cullet quality for a given QC procedure. Using statistical calculations, we optimise and improve the cullet quality control procedures used at the glass plant and/or at the cullet treatment plant to reach a wanted level of precision and accuracy. - Picture

- Colour change assistance and colour change procedure optimisation using our vast experience from dozens of colour changes. Using our batch recipe modification procedure and furnace settings strategy, we minimise transition time, glass quality losses (blisters, foaming, ...) and 'out of colour specs' production losses. In favourable conditions, using our advanced techniques for redox changes and applying overdose techniques,the transition time can be less than 12 hours for a 100tpd furnace - Picture

- Glass breakage expertise; expert witness; glass breakage assessment. - Picture
24: detailed study of all parameters having impact on the glass breakage throwing bottles and jars in large glass recycling containers. Based upon the results of this study, an improved design of these recycling containers was elaborated and tested. Results showed a significant decrease of the glass breakage. Glass recycling companies highly prefer bottles and jars with a low degree of breakage as unwanted impurities like ceramics and vitro-ceramics can be sorted out much more efficiently.
