The thermo-mechanical recyclability potential of biodegradable biopolyesters: Perspectives and limits for food packaging application
01/07/2022 - Up to now, recycling has been opposed to biodegradability, although these two end-of-life options are complementary. If combined in an integrated system, recycling creates an after-use economy,...
Fast successive self?nucleation and annealing (SSA) thermal fractionation protocol for the characterization of polyolefin blends from mechanical recycling
29/04/2022 - The sorting stage of mechanical recycling of post?consumer polyolefins has severe challenges. Polypropylene (PP) is often contaminated with polyethylene (PE) and vice versa. To meet quality...
Application of polyvinylidene fluoride membrane with demulsification property in oil–water separation
27/04/2022 - The wide use of poly(ethylene terephthalate) (PET) for single use packaging and textiles has led to a need for broader recycling methods. Chemically depolymerizing waste PET into base monomers is an...
Melting Temperature Depression of Polymer Single Crystals: Application to the Eco-Design of Tie-Layers in Polyolefinic-Based Multilayered Films
17/04/2022 - In this paper, we describe a method for determining polymer compatibility, which will aid in establishing the requirements of polyolefinic materials for the eco-design of multilayer films for...
Critical advances and future opportunities in upcycling commodity polymers
30/03/2022 - The vast majority of commodity plastics do not degrade and therefore they permanently pollute the environment. At present, less than 20% of post-consumer plastic waste in developed countries is...
Multiple recycling of a PLA/PHB biopolymer blend for sustainable packaging applications: Rheology?morphology, thermal, and mechanical performance analysis
26/03/2022 - PLA/PHB (70/30 wt.%) blend was prepared and reprocessed for 5 times through an industrial scale twin screw extruder. Multiple recycling partially improved interfacial interaction of the two phases...
Assessment of the Eco-Efficiency of the Circular Economy in the Recovery of Cellulose from the Shredding of Textile Waste
24/03/2022 - There is a growing demand for the adoption of cyclical processes in the fashion industry. The trends point to the reuse of cellulose from cotton fibres, obtained from industrial waste, as a...
Mechanical recycling of plastic waste as a point source of microplastic pollution
- Plastic pollution has become one of the most pressing environmental issues. Recycling is a potential means of reducing plastic pollution in the environment. However, plastic fragments are still...
Statistical entropy of resources using a categorization tree for material enumeration: Framework development and application to a plastic packaging case study
01/06/2022 - Statistical entropy has been proposed as a metric of the quality of a mixture of materials, capturing its degree of complexity. An often overlooked challenge to applying this metric lies in the...
Sustainable Cellulose-Aluminum-Plastic Composites from Beverage Cartons Scraps and Recycled Polyethylene
19/02/2022 - The sustainable management of multilayer paper/plastic waste is a technological challenge due to its composite nature. In this paper, a mechanical recycling approach for multilayer cartons (MC) is...
Wind turbine blade end-of-life options: An economic comparison
01/05/2022 - Global wind energy is developing rapidly, with total installed capacity having increased from 24,332 MW in 2001 to 650,758 MW in 2019. Environmental concerns have been raised over the large...
Chemical testing of mechanically recycled polyethylene terephthalate for food packaging in the European Union
01/04/2022 - Polyethylene terephthalate (PET) is a polymer deemed safe to be mechanically recycled and used in food contact applications. Its recycled form (rPET) can be used as a food contact material (FCM)....
A Cost Modelling System for Recycling Carbon Fiber-Reinforced Composites
01/12/2021 - Cost-effective and environmentally responsible ways of carbon fiber-reinforced composite (CFRP) recycling are increasingly important, owing to the rapidly increasing use of these materials in many...
Investigating thermomechanical recycling of poly(ethylene terephthalate) containing phosphorus flame retardants
