“…Novel recycling methods include the use of hydrometallurgy to separate aluminium from polyvinyl chloride, enabling recycling of pharmaceutical blister packs in China. 28 However, it must be acknowledged that in low-income settings, plastic recycling may be poorly developed or non-existent, and incineration of plastics may be low-tech, leading to incomplete combustion and release of hazardous pollutants such as dioxins and heavy metals.…”

“…Moreover, it is projected that the pharmaceutical packaging market will reach 111.9 billion USD by 2026 following a compound annual growth rate (CAGR) of 8.75%. Waste pharmaceutical blisters (WPBs) are one of the major segments of pharmaceutical waste packaging [63,64] and consist of an average of 80-85 wt% of plastic films and 10-20 wt % of aluminum foils [65]. They are mainly disposed of by incineration and landfilling in municipal solid waste.…”

In this review, life cycle assessment (LCA) principles are coupled with circular economy (CE) in order to address LCA examples in the biomedical sector worldwide. The objectives were (1) to explore the application of LCA in the medical, pharmaceutical, and dental fields; (2) to describe the ways of biomedical waste management; (3) to emphasize on the problem of dental waste in private and public dental sectors; and (4) to propose ways of "green circulation" of the dental waste. A literature search was performed using the Google Scholar, PubMed, and Scopus search engines covering the period from January 2000 until May 2020, corresponding to articles investigating the LCA and circular economy principles and legislation for biomedical and dental waste, their management options, and modern ways of recycling. The results showed that incineration seems to be the best management way option involved despite the mentioned drawbacks in this technology. Different adopted models are well defined for the dental field based on the 3Rs' module (reduce, reuse, recycle). Replacing disposable products with reusable ones seems to be a good way to tackle the problem of waste in medical and dental sectors. Interventions on the selection and better biomedical and dental waste management will ensure eco-medicine and eco-dentistry of the future. These new terms should be the new philosophies that will change the way these fields operate in the future for the benefit of the professionals/patients and the community.

“…This type of structure, consisting of aluminum (lidding material) and plastics (forming film), such as polyvinyl chloride PVC, polypropylene (PP), polystyrene (PS) and/or polyethylene (PE), makes the recycling of aluminum from WBPs notably more difficult and complex compared to typical aluminum recycling. 6,7 Two types of WPBs are commonly utilized by the pharmaceutical packaging industry: Type I: aluminum and a single layer of plastic; Type II: aluminum and a multilayer of plastic.…”

“…5 In contrast to the mechanical route for the separation of the aluminum and plastic fractions, the chemical route has also been studied extensively in recent years. Wang et al 7,17 studied the leaching of aluminum from WPBs with two different leaching agents, viz., sodium hydroxide and hydrochloric acid. The results of both the studies, under optimized conditions, showed high recovery rates of aluminum (up to 100%).…”

Waste pharmaceutical blister packages (WPBs) are a source of solid waste, which are composed of plastics and aluminum, therefore acting as a potential source for secondary aluminum. The structure of WPBs makes the recycling of aluminum notably more complex than typical aluminum recycling. Currently, WBPs are disposed of as municipal solid waste; thus, aluminum is lost from the circulation during incineration. In this work, three types of WPBs were studied, each with two plastic layers and a metallic layer. Delamination of WPBs to separate aluminum and plastic(s) was investigated by using a solution of organic solvents. The effects of temperature (30–50°C), acetone to isopropanol ratio (0–100 vol.%) and different types of WPBs on delamination behavior were investigated. The results suggest that aluminum separation and recovery from WPBs is 100% at optimum conditions. Moreover, an overall indicative flowsheet for recycling and post-processing of segregated aluminum from the plastic is also suggested.
