Ensuring quality in rPET preforms
Piovan has highlighted the benefits of its Inspecta gas chromatography analysis instrument in connection with recycled PET. Inspecta can detect the presence of volatile substances to help guarantee the quality of PET preforms, which is particularly useful when rPET is used. Substances such as acetaldehyde can have an impact on the taste of the beverage that is bottled inside and for this reason their concentration has to be kept under control, it says.
Inspecta can be installed in the
production area without needing to test samples in the laboratory. This makes the analysis compatible with the production timing, allowing prompt corrective actions. There are two possible configura- tions for the layout: laboratory version with a dedicated compact cabinet for desk installation or as a turret with a
Piovan’s Inspecta instrument can be installed in a lab or on the production floor
cabinet for floor installation. In this second case a hydrogen generator is included to make the analysis stationing totally independent. The control software has been designed in order to make the analysis
profitable use. It can also provide insights into the effectiveness of an entire recycling process and help ensure that individual plant components are functioning as they should.” A combination of up to three different types of sensor (for colour, near infrared, and metal) automatically provides precise, reproducible analyses of material samples by detecting colour errors, plastic types, and metallic contaminants. The composition of each batch of plastic flakes can be determined within minutes. Representative results can be reached with a sample volume as small as eight litres. Running flat out, Flake Scan can analyse up to 20kg/h. Sesotec says the device is easy to operate, with an intuitive touchscreen as well as automated reporting and archiving. In a new e-book, Tomra Sorting Recycling looks
at how connected machines and cloud-based data storage is transforming how businesses collect, access, and analyse data. In “Digitalization – Con- nect to Enhance Productivity in the Recycling Industry,” Tomra says this capability is ushering in a new era of data-driven process optimisation. It says: “Prior to Industry 4.0 and the Industrial Internet of Things, production data remained local to optical sorters, making it difficult to harvest and

analyse. Now, through embedded sensors and cloud-based reporting, optical sorters are turned into data delivery machines to drive the strategic management process. Near real-time data gives insight into production gaps, allows companies to react faster to change and improves recycled product quality and throughput.” The e-book examines how stored service
reports, spare parts orders and product manuals improve machine maintenance efficiency. It also peers into the not-so-distant-future where lever- aged production data, combined with advanced analytics, will result in the development of new sorting technologies and processes that will improve sorting efficiency and boost final product purity.
