Where are Residual Sodium Chemicals purified for recycling, and by whom ?
Apart from the case of ‘direct recycling’, the purification of RSCs with a view to recycling must in general be carried out in sufficiently large units in order to benefit from the effect of scale. This is particularly true for the RSCs from the municipal solid waste incineration, to be purified and recycled in the production of sodium carbonate. The industrial units SOLVAL and RESOLEST are two examples. In most cases RSC purification platforms are designed in partnership with waste professionals.
