Published: Jan. 18, 2023

Bioplastics are one of the possible alternative solutions to polymers petrochemical origins. have several advantages over traditional plastics in terms low carbon footprint, energy efficiency, biodegradability and versatility. Although they numerous benefits revolutionizing many application fields, also weaknesses, such as brittleness, high-water absorption, crystallization ability thermal degradation temperature. These drawbacks can be a limiting factor that prevents their use applications. Nonetheless, reinforcements plasticizers added bioplastic production way overcome limitations. materials not yet studied depth, but it is with great optimism industrial market scenarios increasing; growth positive driver for more research this field. National international investments bioplastics industry promote green transition. International projects, EcoPlast Animpol, aim study develop new polymeric made from sources. One biggest problems waste management; there no separation process recycle nonbiodegradable bioplastics, considered contaminants when mixed other polymers. Some additives, impact on microplastics leave after breaking apart subject debate. For reason, important consider life cycle analysis assess environmental viability. possibly processed various ways, including conventional processes used ones. Those include injection moulding extrusion, well digital manufacturing. This possibility these applications greatest strengths. All aspects will discussed review.

Abstract This review explores the potential of genetically engineering cyanobacteria with aim synthesizing high‐value protein directly from atmospheric nitrogen. The article examines numerous techniques that may enhance synthesis in cyanobacteria, and discusses advantages, barriers, opportunities for this strategy going forward. Genetic manipulation shows promise sustainably raising production via reduced greenhouse gas emissions lower dependence on synthetic fertilizers, but also potentially fewer environmental implications traditionally caused by conventional methods. uncovers many difficulties modifying production. For example, modified organisms (GMOs) have legal regulatory ramifications must be accounted if ethical, moral secure use these technologies is to ensured. Economic viability, too, evaluated, taking into consideration costs, scalability, market demand future potential. We suggest processing cyanobacterial proteins downstream stages need further development. Effective economical methods are needed extraction, purification, formulation commercially viable products. successful application at scale, such obstacles overcome. conclude genetic has a great deal offer resource‐effective sustainable replacement proteins, so promoting more environmentally conscious future.
