Highly efficient recovery of high-purity Cu, PVC, and phthalate
Thus, the developed methods allow for the successful quantitative recovery of high-purity Cu, PVC, and DINP without requiring any of the complex multistep physical separation processes involved in the conventional granulation technique for the recycling of waste wire harnesses.

Current Status of Plasticizer Research | SpringerLink
The purity of HHPA is analyzed using a Shimadzu GC-14B spectrometer with a hydrogen flame ionization detector, XE-60 on ChromaSorb W-AW-DMCS (60–80 mesh) stainless steel column, and C-R6A data processer. Acetone is used as the eluent solvent.
Treatment of DEHP-rich PVC waste in subcritical urine wastewater
The high content of chlorine and plasticizers is the main obstacles of the PVC waste dispose due to the corrosion of chlorine and toxicity of plasticizers (Pan et al., 2025). The traditional treatment methods of PVC waste can cause huge environmental problems such as emissions of greenhouse gases and other highly toxic chlorinated organic pollutants ( Suresh et al., 2017 , Osada and Yana, 2010 ).

Taylor Vortex Flow Chemical Reactor - Lab to Mass Production
Not only that, the Taylor Reactor uses homogenous micro-mixing zones to produce high purity products with uniform-sized particles and minimize loss of input materials. Since it brings significant improvements in productivity, purity, uniformity and density, the Taylor Reactors are being used globally for a wide range of applications in the USA, France, Germany and Korea and etc.
- What type of plasticizer is used to modify PVC?
- Phthalate esters (e.g., di-2-ethylhexyl phthalate «DEHP» and diisononyl phthalate «DINP») are the main type of plasticizers used to modify PVC [ 1 ]. In 2022, phthalate esters accounted for more than 3 million tons of global plasticizer consumption [ 2].
- What is a non phthalate ester plasticizer?
- However, due to environmental and health risks, the world use of non-phthalate ester plasticizers is expected to increase to around 2.6 million tons [ 2 ]. The non-phthalate plasticizer dioctyl terephthalate (DOTP or DEHT), is an organic molecule with the chemical formula C 6 H 4 (CO 2 C 8 H 17) 2.
- What is the 2060 Nir-ex analyzer?
- The 2060 The NIR-Ex Analyzer, developed by Metrohm Process Analytics, facilitates the comparison of real-time spectral data from the process with a reference method (such as titration, HPLC, or IC), allowing for the creation of a straightforward yet essential calibration model for the production process.
