Fully bio-based monomers are used in the green synthesis of a vitrimeric poly(acetal) which can undergo both closed-loop mechanical and chemical recycling, fulfilling 11 out 12 chemistry principles.
A hydrophobic biocomposite (HBC) has been developed using a waste wood residue for circumventing oil spill issues. The ease of removal, regeneration and recyclability is demonstrated.
The increasing use of aluminimum in packaging applications results many different aluminium-based products ending up consumer mixed-waste bins. This waste is typically incinerated, generating an aluminium-containing bottom ash. current work investigates the recyclability aluminium fraction ash from incineration plants USA, UK and Denmark. Incinerated Al-samples size fractions (2–6 mm, 6–12 mm 1...
Recyclable flame-retardant epoxy composites based on disulfide bonds: Flammability and recyclability
A series of recyclable epoxy resin (REP) composites are successfully prepared in this study, aiming to improve flame retardancy while keep good recyclability and mechanical properties. The commercial 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-Oxide (DOPO) with high reactive P-H bond is used as highly-efficient retardant work. Compared pure a limited oxygen index 21.7 % no rating vertical burn...
Porphyrin-based supramolecular nanoassemblies of a spherical morphology have been attracting broad interest owing to their wide application possibilities in numerous fields of paramount significance. Most of the existing assembly protocols, however, either suffer from the requirement of elaborately-designed yet tediously-synthesized ad hoc porphyrins, the use of surfactant templates, or accurat...
Multilayer plastic films provide a range of properties, which cannot be obtained from monolayer films but, at present, their recyclability is an open issue and should be improved. Research to date has shown the possibility of using whey protein as a layer material with the property of acting as an excellent barrier against oxygen and moisture, replacing petrochemical non-recyclable materials. T...
In the medical field, the attention to the environmental impact of industrial processes and products is still limited. In recent years there has been an increased sensitivity towards the environment; meanwhile, the economic burden of hazardous waste disposal is becoming evident. Dialysis is a "big producer" of waste and it has been estimated that disposal costs can be up to 10-40% of the cost o...
TPO is getting wider acceptance for automotive applications. An exterior application like a fascia is a very good example. Interiors are still a challenge due to many reasons including overall system cost. For interior applications, “all-olefin” means it mainly consists of three materials: TPO skin, cross-linked olefinic-based foam and PP substrate. The driving force for TPO in Europe is mainly...
