WebJun 14, 2024 · Summary. Mixing determines the environment in which crystals nucleate and grow and is therefore intrinsic to industrial crystallization. Individual nucleating and growing crystals respond directly to their microenvironment and not in a simple way to the macroenvironment, often thought of as the bulk or average environment. WebNew processes are available to recycle those materials by breaking the polymers to its building blocks ethylene glycol (MEG), terephthalic acid (TPA), dimethyl terephthalate (DMT) or bis (hydroxyethyl)terephthalat (BHET). The methanolysis and glycolysis of PET have reached technical maturity, producing DMT, MEG, and BHET. downpatrick town centre
