1. The Recycling Technologies of Mono-material and Multilayer Plastic Film: A Descriptive Literature Review

Author

Rizzo, Maria Vittoria, Carlo Tancredi, Giovanni Paolo, and Vignali, Giuseppe

Abstract

Plastic-based flexible films are widely used in many areas of modern industry, including the food industry. Depending on the application field, mono-material or multi-material films can be used, usually based on polyolefins such as PE and/or PP. Compared to mono-material films, multilayer films offer greater performance and functionality in terms of mechanical and barrier properties, thanks to the different types of polymers used. Considering the end-of-life of the two types of materials, the recyclability of mono-material film turns out to be much greater than that of a multilayer, since only one type of polymer can be handled in specific and specialized streams. The biggest issue with multilayer films is precisely end-of-life management, which currently appears to be mainly landfilling or waste-to-energy. In recent years, the use of increasingly sustainable packaging has become a prerequisite. The issue of recycling is of fundamental importance because of the implementation of a circular economy. This review aims to investigate recycling methodologies for both mono-material and multi-material films, from traditional ones, such as mechanical recycling, to more modern technologies not widely used in industry, such as delamination and chemical recycling.

Abstract

Introduction: The prevalence of maternal group-B-streptococcus (GBS) colonization and risk factors (RFs) for neonatal early-onset disease (EOD) in Europe are poorly defined. Large-scale information concerning adherence to recommendations for preventing GBS-EOD are lacking.Materials and Methods: This was a 3-month retrospective area-based study including all regional deliveries  ≥35 weeks' gestation (in 2012). The sensitivity, specificity, positive and negative predictive values, odds ratio and receiver operating characteristic (ROC) curve for intrapartum antibiotic prophylaxis (IAP) among full-term and preterm deliveries and prolonged membrane rupture (PROM) were calculated.Results: Among 7133 women, 259 (3.6%) were preterm (35-36 weeks' gestation). Full-term women were 6874, and 876 (12.7%) had at least 1 RF. Most women (6495) had prenatal screening and 21.4% (1390) were GBS positive. IAP was given to 2369 (33.2%) women (preterm, n = 166; full term, n = 2203). Compared to full-term, preterm women were less likely to receive IAP when indicated (73.2% versus 90.3%, p < 0.01). Full-term women represented the largest area under the curve (AUC, 0.87). PROM showed the highest sensitivity (98.6%), but the lowest specificity (6.9%) and AUC (0.53).Conclusions: Large-scale prenatal screening and IAP are feasible. Women delivering preterm are less likely to receive IAP when indicated. Most unnecessary antibiotics are given in cases of PROM. [ABSTRACT FROM AUTHOR]
