The invention relates to a solvent-based separation method for the total material recycling of materials used in nonwoven, woven, and tufted wares into the individual material components thereof sorted by type. At least one of the materials contains a polyolefin wax. As a solvent and/or swelling agent, halogen-free, aliphatic hydrocarbons or aromatic hydrocarbons or a mixture of one or several of said solvents are used.

Method for recycling floor coverings

The invention relates to a novel flame retardant and stabilizer combined for thermoplastic polymers, which comprises, as component A, from 20 to 80% by weight of a phosphinic salt of the formula (I) and/or of a diphosphinic salt of the formula (II), and/or polymers of these, where
