The need for sustainable development has never been more urgent, as the world continues to struggle with environmental challenges, such as climate change, pollution, and dwindling natural resources. The use of renewable and recycled waste materials as a source of raw materials for biomaterials and tissue engineering is a promising avenue for sustainable development. Although tissue engineering has rapidly developed, the challenges associated with fulfilling the increasing demand for bone substitutes and implants remain unresolved, particularly as the global population ages. This review provides an overview of waste materials, such as eggshells, seashells, fish residues, and agricultural biomass, that can be transformed into biomaterials for bone tissue engineering. While the development of recycled metals is in its early stages, we highlight the use of probiotics and renewable polymers to improve the biofunctionalities of bone implants. Despite the advances of additive manufacturing (AM), studies on AM waste‐derived bone‐substitutes are limited. It is foreseeable that AM technologies can provide a more sustainable alternative to manufacturing biomaterials and implants. The preliminary results of eggshell and seashell‐derived calcium phosphate and rice husk ash‐derived silica will likely pave the way for more advanced applications of AM waste‐derived biomaterials for sustainably addressing several unmet clinical applications.This article is protected by copyright.

“…Compared to the overall plastic and resin industry, bioplastic manufacturing falls short significantly in size with an estimated revenue of $864.7 million for 2022 (Bari, 2022). First and second-generation bioplastics, i.e., those sourced from crops and those sourced from lignocellulosic feedstocks, have achieved some degree of industrial scales, but incurred higher production costs (OECD, 2013;Gong, et al, 2023). True cost-saving economies of scale are yet to be achieved given technical and supply chain constraints sufficient, and an inability to attract sufficient investments.…”

Bioplastics have the potential to fill the role of conventional plastics but with lowered environmental and ecological impacts. But bioplastic production suffers from high production costs and as an immature technology, it proves less competitive than its petrol-based counterpart. Debates about the social versus private benefits of bioplastics are also cited. The literature argues that various bio-feedstock sources can produce high-quality drop-in plastics and that scaling up bioplastic production will provide the cost competitiveness needed to transition away from petroplastics. However, the market remains uncoordinated and lacks a strategic and comprehensive plan for the plastic transition. Moreover, the science-to-policy literature on bioplastics is very limited, providing scarce evidence or analysis to policymakers attempting to argue for bioplastics industrialization and integration. In this study we highlight this missing link particularly in the North American context in order to encourage further inquiry on these matters. Using Stern’s policy framework gap analysis approach, our evaluation identifies gaps in existing policy frameworks pertinent to bioplastics supply chains. On this basis we identify and prioritize five pointed areas for policy focus to advance bioplastics sector growth and integration. These are developing a strategy to sustainably coordinate and promote biomass production; incentivizing bioplastic investments and production; incentivizing bioplastic substitution; and enhancing the end-use management. Additionally, research is needed to support the technical performance of bioplastics, industrialization methods, supply chain integration, and the impact of exogenous factors.

“…Previous literature has examined various facets of bioplastics, including their environmental benefits, production from different waste sources such as food, vegetables, downstream processing, and stability in different environments. For instance, Lavagnolo et al [ 41 ] delved into the stability of bioplastics in aquatic environments, while Gong et al [ 42 ] and Ali et al [ 43 ] summarized bioplastic production from fruit-vegetable residues and organic waste, respectively. Additionally, Bhat et al [ 44 ] addressed greener approaches for bioplastic recovery.…”

Background Plastic is widely utilized in packaging, frameworks, and as coverings material. Its overconsumption and slow degradation, pose threats to ecosystems due to its toxic effects. While polyhydroxyalkanoates (PHA) offer a sustainable alternative to petroleum-based plastics, their production costs present significant obstacles to global adoption. On the other side, a multitude of household and industrial activities generate substantial volumes of wastewater containing both organic and inorganic contaminants. This not only poses a threat to ecosystems but also presents opportunities to get benefits from the circular economy. Main body of abstract Production of bioplastics may be improved by using the nutrients and minerals in wastewater as a feedstock for microbial fermentation. Strategies like feast-famine culture, mixed-consortia culture, and integrated processes have been developed for PHA production from highly polluted wastewater with high organic loads. Various process parameters like organic loading rate, organic content (volatile fatty acids), dissolved oxygen, operating pH, and temperature also have critical roles in PHA accumulation in microbial biomass. Research advances are also going on in downstream and recovery of PHA utilizing a combination of physical and chemical (halogenated solvents, surfactants, green solvents) methods. This review highlights recent developments in upcycling wastewater resources into PHA, encompassing various production strategies, downstream processing methodologies, and techno-economic analyses. Short conclusion Organic carbon and nitrogen present in wastewater offer a promising, cost-effective source for producing bioplastic. Previous attempts have focused on enhancing productivity through optimizing culture systems and growth conditions. However, despite technological progress, significant challenges persist, such as low productivity, intricate downstream processing, scalability issues, and the properties of resulting PHA.
