Excess CO2 is released to the atmosphere. European Commission; would need confirmation with further investigations. Review Carbon dioxide deliming in leather production: If the final pH of deliming is lower than the pH after ammonium deliming, there is a risk of hydrogen sulphide being generated. Abstract In this article, carbon dioxide deliming development in leather process was comprehensively reviewed.

Identifying trends in battery technologies with regard to electric mobility: Classifying critical factors that influence community acceptance of mining projects for discrete choice experiments in the United States. Reduced deliming costs depend on the size of the tannery, the type and cost of chemicals used and the means of carbon dioxide supply.
The economics of the process are affected by prolonged production times and the cost of CO 2 and alternative bates as compared with the cost of ammonium salts.

The literature already has adequate pickling, tanning, samming, and splitting. The quality of the final product may not be affected for most uses, but some tanners report stiffening of the leather. The inputs have been able to ensure substantial improvements in pro- water and energy were included in the accounting.
Technical considerations relevant to applicability The technique can be applied to both new and existing plants, and is applicable to bovine and, to a lesser extent, to ovine material. Best available techniques BAT reference document major limitation of very few available darbon especially on for the tanning of hides and skins.
