Can pharma-grade solvents be re-refined?

Yes — pharmaceutical solvents (07 05 03*, 07 05 04*) are among the highest-value solvent recovery feedstocks due to their high purity. Single-solvent streams like IPA or acetone can be recovered to 99%+ purity, worth €300–600/t recovered.

What is the difference between co-processing and incineration for API residues?

Co-processing in cement kilns (under the Industrial Emissions Directive) uses the calorific value of API residues as fuel while inorganic content becomes part of the clinker — zero ash. Purpose-built incinerators destroy the waste but generate ash requiring further disposal.
