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 in 2019
The first meeting of 2019 was hosted by AGC at Louvain-La-Neuve, Belgium. The meeting had a full agenda and the thirteen participants (including one invited guest) discussed many important environmental and health issues associated with the manufacture of different types of glass.
The meeting started with ICG business, which included discussion on expanding the committee membership to include more representatives from container glass, management of the website and Project ICG 2030.
SOx emissions and the difficulty meeting the BREF limits with current abatement technologies was then discussed, which led to a later presentation on the Sorb Saver system from America which can help improve absorption efficiency.
It was confirmed that the TC13 work on respirable crystalline silica in sand had been published in the Glass Worldwide, January/February 2019 edition. The committee then reviewed the REACH dossier for glass and decided that it should be updated to include new information.
The committee then covered the topic of furnace emissions, which included discussion on methods for SO3 measurement and a comprehensive presentation on comparative tests, which demonstrate the suitability of FTIR for measurement of HCl, SO2, NOx and NH3. There was discussion on PCB measurements and how results close to and less than the blank value should be reported. Results of emissions measurements of boron and mercury from container glass were also presented. These highlighted a potential issue in Germany where new draft limits have been proposed.
The second meeting of 2019 was hosted by Saint Gobain at their German and Eastern Europe headquarters in Aachen, Germany. The meeting had a full agenda and the sixteen participants (including three invited guests) discussed many important environmental and health issues associated with the manufacture of different types of glass.
The committee first discussed ICG issues which included changes to membership and potential new members, improvements to the TC13 websites hosted by ICG and Celsian and the proposal to make 2022 the United Nations International Year of Glass for 2022.
There was a presentation on the design of an abatement system to remove boron from the waste gas emissions of a tableware furnace. The factors affecting the removal efficiency were discussed as well as the recycling of the boron filter dust into the furnace.
The group then considered the revision of the TC13 leaching method which is used to determine whether a glass substance requires registering under REACH. The group agreed to revise the paper as long as further information becomes available on limits for boron leaching and examples of where the method has been used.
The committee then addressed emissions from glass furnaces. This included discussion on the formation of condensable particulate after a ceramic catalytic filter, a presentation on the Sorb Saver system and a summary of NOx emissions limits in the Italian glass industry. There was also a comprehensive presentation on measurement of dioxins and PCBs and discussion on quality control requirements and treatment of the blank values.
The group then went on to discuss ceramic candles filter elements and the different methods of manufacture.
The meeting concluded with a round table on regulations and new abatement plants.
PLANS FOR 2020
There are two meetings planned for 2020. The first will be in hosted by Schott in Germany on 24th and 25th March. The second will be held in the Autumn and will be hosted by either Guardian or Sisecam.
The rolling assessment of environmental issues addressed at each meeting will continue. This will include discussions on the recycling of flue gas filter dust, the REACH leaching method, emissions measurement techniques, conversion of SO2 to SO3 in SCRs, measurement of dioxins and PCBs and the performance of new abatement systems.
The committee plans to publish a paper discussing the calculation of flue gas volume flow and may also publish an update to its paper on the TC13 REACH leaching method.
