TC13: Environment

Vision: Protecting the planet and making glass.

Mission Statement: The mission of TC13 is to achieve best practice by exchange of information concerning current and developing techniques for reducing the environmental impact of glass during its production, use and disposal. This shall include the comparison of the results of different control techniques and the determination of best practice for measuring pollutants (primarily total particulate, NOx, SOx, HCl, HF & heavy metals) by means of parallel measurements, material balances, and round robin tests.

Action plan for the next 5 to 10 years: With emission limits becoming tighter and more expansive there is a critical need for better and more reliable measurements methods. TC13 will help provide the glass industry with adapted and affordable standard protocols, and it will help the industry benefit from new monitoring and emission control technologies.

Activities and planned actions


The first TC13 meeting of 2016 was held in Chapeltown, near Sheffield, England at the offices of British Glass. Mr. Laurent Piranda chaired the meeting and Dr. Simon Slade was the secretary. The meeting had a typically full agenda and was well-attended with the eighteen participants discussing many important environmental issues associated with the manufacture of glass. St. Gobain and Arc provided further updates on the operation of their Cercat ceramic catalytic bag house, and the measurement of emissions of boron, selenium, and ammonia were discussed by the committee.

There were detailed presentations by SSV of both their work on the PRIME project to develop novel primary NOx control techniques and also on their work to monitor dust and respirable crystalline silica in the glass factory workplace. The respirable fraction of glass-making sand was also discussed and the meeting concluded with a tour de table on new regulations and abatement installations. The extensive minutes provide a thorough record of the discussions, and were issued to TC13 members along with the presentations made at the meeting.

The second TC13 meeting was hosted by CelSian, in Eindhoven, in The Netherlands. Dr. Andreas Kasper chaired the meeting and Dr. Simon Slade was the secretary. The typically busy meeting had 13 participants who discussed many important environmental and health issues associated with the manufacture of different types of glass. The committee heard about problems with EP dust recycling in USA, both from a technical and from a regulatory point of view. The use of EP dust sometimes has technical difficulties for the glass-maker, but there may also be some significant regulatory concerns.

There was also an interesting presentation of an on-going German project to assess the impact of increased recycling of cullet and EP dust on the accumulation of unwanted components in the furnace system. High cullet use and EP dust recycling are good environmental practices, but may be associated with an increase in halides and heavy metals in the glass and in the emissions. There were also short updates on: the operation of a Cercat ceramic catalytic bag house; the measurement of emissions of boron and selenium; the impact of NH3 on measurements of emitted SOx; an inexplicably high SO2 measurement; and the CO+ sensor developed by CelSian.

Finally, the committee considered the presence of respirable crystalline silica in various glass-making sands. The committee heard an interesting presentation by an invited guest from the sand suppler Sibelco, and the draft of a TC13 paper to be published in early 2017 on the subject was discussed. The usual extensive minutes provide a thorough record of the discussions, and were issued with the presentations made at the meeting.


There are two meetings planned for 2017. The first will be in Ladenburg, Germany hosted by St. Gobain Isover, on 3rd and 4th April. The second will be held in September, hosted by PQ, in Wurzen, Germany. The rolling assessment of environmental issues addressed at each meeting will continue. In particular, two important on-going practical studies will be reported in detail: furnace emissions and the influence of recycling; and respirable crystalline silica in glass-making sand and in the workplace The TC13 paper on respirable crystalline silica in glass-making sand will be published in early 2017.
