Bioplastics from waste biomass of marine and poultry industries.

Plastics are indispensable and typically derived from non-renewable sources. The extensive production and indiscriminate use of synthetic plastics pose a serious threat to the environment and lead to problems due to their non-biodegradability. Various forms of plastics that are used in daily life should be limited and replaced by biodegradable materials. To deal with the challenges of sustainability or environmental issues that occur due to the production and disposal of synthetic plastics, biodegradable and environment-friendly plastics are crucial. Utilizing renewable sources such as keratin derived from chicken feathers and chitosan from shrimp cell wastes as an alternative to obtain safe bio-based polymers has gained much attention because of rising environmental issues. Approximately, 2-5 billion tons of waste are produced by the poultry and marine industries each year, adversely impacting the environment. These polymers are more acceptable and ecofriendly compared with conventional plastics due to their biostability, biodegradability, and excellent mechanical properties. The replacement of synthetic plastic packaging with biodegradable polymers from animal by-products significantly reduces the volume of waste generated. This review highlights important aspects such as the classification of bioplastics, properties and use of waste biomass for bioplastics production, their structure, mechanical properties, and demand in industrial sectors such as agriculture, biomedicine, and food packaging.

Qualitative exploration of perspectives of the pharmacists working in public-sector hospitals during COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic, a serious global health threat, has excruciating social and economic implications given its transmissibility, lack of therapy, and severity. In such a situation, pharmacists as frontline healthcare professionals hold a significant position to tackle. This study was designed to explore the perception and preparedness of pharmacists working in public sector hospitals amid such a pandemic in Pakistan. METHODS: A total of 11 pharmacists were interviewed for this qualitative study design through a semi-structured interview guide. The interviews were recorded and transcribed verbatim. RESULTS: The thematic content analysis yielded six major themes; understanding of COVID-19, perceptions towards COVID-19, preventive aspects, management aspects, changes to lifestyle, and psychological aspects. Though efficient preparedness and approach to fighting against such pandemics were reported, pharmacists were found susceptible to infection and psychological stress. They also expressed lockdown as an effective measure to prevent the disease from spreading but still were concerned about its economic and social impact. CONCLUSIONS: Adequate planning and facilities from the national level should be made available for strengthening the hospital pharmacy service that helps improve the overall healthcare system of low- and middle-income countries like Pakistan. The provision of a protective facility, incentives, and occupational health surveillance packages are deemed necessary to boost the self-esteem and morale of hospital pharmacists that safeguard the early and effective management of such disasters.
