Fate and effects of soluble silicate (waterglass) emissions to surface waters
In line with the principles of Responsible Care, CEES is interested in the fate and (potential) effects of soluble silicates that enter water ecosystems through the water route. In August 2000, CEES has commissioned TNO (Netherlands Organisation for Applied Scientific Research) to carry out a desk study to assess the fate and effects of soluble silicates. This report is the result of this study.
The main conclusion of the report shows that due to the complexity of interacting processes there remain some uncertainties regarding the effects of silicates on water ecosystems. Based on thorough review of literature and on our own investigations and modelling calculation, no significant adverse effects to human health and to ecosystems are to be assumed.
The executive summary can be downloaded directly from our website. Copies of the full report may be requested from TNO, or from the Cefic Secretariat or from any of the supporting CEES members.

Life Cycle Inventories for the Production of Sodium Silicates
For the most common sodium silicate products, which represent more than 90 % of total alkali silicate production, Life Cycle Inventories (LCI) have been prepared on behalf of CEES by EMPA (Swiss Federal Laboratories for Materials Testing and Research), St. Gall in 1997 (EMPA Report No. 241). Copies of the report are available either directly from EMPA, or from the Cefic Secretariat or from any of the supporting CEES members.
These LCI’s give averaged figures (based on measured values) for the consumption of raw materials, water and energy and for emissions to air and water along with solid waste generation for the five most common, commercially available sodium silicate products. Data were supplied by twelve West European silicate producers, all CEES members and were based on 1995 production figures.
A short version of this LCI study highlighting the key findings has been published in the International Journal of Life Cycle Analyses (Int. J LCA 4(4), p.207-212, 1999). Copies can be obtained either directly from the Cefic Secretariat or from any supporting CEES member.
