Gypsum industry news

France: Etex subsidiary Siniat plans to install a new boiler, fired by either solid recovered fuel (SRF) or waste wood, at its Auneuil gypsum wallboard plant in Oise Department. The producer expects this to reduce the plant's gas consumption by 20%. The L'Usine Nouvelle newspaper has reported that the project is part of a planned Euro30m sustainability overhaul of equipment at the plant before 2026. Siniat recently brought the Auneuil plant back online following the installation of a new Euro15m dryer in early 2023, which increased wallboard drying times by 10% and reduced gas consumption by 20%. The producer said that this has eliminated 5900t/yr of CO₂ emissions.

From the remaining Euro3m of its allotted budget for sustainability upgrades, Siniat will build a gypsum recycling plant at the Auneuil gypsum wallboard plant. It currently receives its recycled gypsum from Ritleng Revalorisations' gypsum recycling plant in Rohr, Bas-Rhin Department. Currently, natural gypsum from the Le Pin-Villeparisis and Montmorency mines accounts for 40 - 60% of the Auneuil plant' gypsum consumption.

Belgium: Etex's sales were Euro3.74bn in 2022, up by 25% year-on-year from 2021 levels. Its building performance division, which includes gypsum wallboard, recorded revenues of Euro2.43m, 65% of the group total. Etex said that the division’s market positions and results 'evolved positively,' and 'demonstrated leadership' in the face of raw materials price rises. The group's recurring earnings before interest, taxation, depreciation and amortisation (REBITDA) totalled Euro645m, up by 13%.

During the year, Etex's Romania-based subsidiary Siniat commissioned its new Euro1m gypsum drying and micronisation plant at its Aghiresu gypsum wallboard plant in Cluj. The market yielded turnover growth of 17% year-on-year for Siniat, to Euro72.5m

Etex recycled 54% more gypsum than in 2018 across its operations, making it 'the most advanced gypsum recycler in Europe,' according to the company. Its absolute CO₂ emissions fell by 20% over the same period.

Germany: Gebr. Pfeiffer says it is planning to use its TRT Triplex dryer to partially calcine gypsum. Testing at the Gebr. Pfeiffer test station has yielded ‘positive’ results and further installations are being considered to explore the concept. The product uses the uniflow principle, where both material and hot gasses flow in the same direction and pass through the dryer tubes from the centre outwards.

The engineering company has received an order for a TRT 5000/8.0 Triplex dryer from Shree Cement in India. The dryer will be used to dry flue gas desulphurisation (FGD) gypsum from a captive coal-power plant for use in cement plants. In the planned dryer plant the moisture of the FGD gypsum will be reduced to a residual moisture of <2%. Artificial gypsum from the dryer will be used at other cement grinding plants in the country. The 50t/hr dryer will be installed at the end of 2018 and is expected to start commercial operation in mid-2019.
