Bio-polymer composites have gained much popularity for the development of eco-friendly devices and biodegradable products. Clean, pollution-free environment and reduction of waste materials is the need of the hour. Being biocompatible and biodegradable, these polymers offer a solution. The utilization of bio-polymer composite is not limited as an alternative to the petrochemical-based material but these are progressively being equipped in electronics, medicine, pharmaceutics, construction, automobile industry, packaging, adhesive industry and so forth. The smart bio-polymers are light-weight, possess higher strength, good thermal properties, low density and require less energy while integrating and assembling. As green technology is the demand of the future, the production of biodegradable composites, bio-binders and bio-fibers is the toughest challenge. This review paper strives to specifically address the mechanical and electrical properties of bio-polymer composites and their applications in electronic and mechanical industries.

“…Smetana et al [30] showed that for Arthrospira platensis, replacing an open raceway reactor with a tubular design decreases half of the system impact. On the other hand, the use of outdoor cultivation, which can reduce the impact caused by artificial lighting, could reduce productivity due to fluctuations in light availability [44].…”

Cyanobacteria have long attracted market interest as a source of natural compounds such as pigments with proven bioactivity (carotenoid and phycobiliproteins). The cultivation and extraction processes for such compounds have been developed at different levels, from laboratory trials to photobioreactors on a demonstration scale. Based on this experience, it is possible to propose how the different stages of the process can be improved based on environmental performance indicators. The Life Cycle Assessment (LCA) methodology allows to identify the hotspots that represent the greatest environmental impacts and to propose strategies to focus on those stages that can be improved. The general environmental indicators have been identified and the results showed that cyanobacteria cultivation has the greatest influence on environmental impact for all scales considered (from 20 L to 100 m3), which is attributed to the energy requirements. The main changes proposed to reduce the impact should focus on the stages of reactor cleaning, culture medium sterilisation and biomass drying. The implementation of these improvement alternatives can reduce the impact of the production and extraction processes by 85%. This work demonstrates how technological development must go hand in hand with impact assessment to make the best decisions in the overall process.

Departing from the conventional axenic and heterotrophic cultures, our research ventures into unexplored territory by investigating the potential of photosynthetic microbiomes for polyhydroxybutyrate (PHB) production. A cyanobacteria-rich microbiome was harnessed for PHB production in a 3 L photobioreactor under non-sterile conditions. The robust culture achieved up to 28 %dcwPHB over 108 days of alternating growth and accumulation phases. Nile Blue staining and Transmission Electron Microscope visualization successfully confirmed the presence of PHB granules within cyanobacteria cells. Analysis through proton Nuclear Magnetic Resonance further validated the extracted polymer as PHB. In addition, the overexpression of the enzyme PHA synthase throughout the accumulation phase correlated directly with the increased PHB production. Also, gene expression changes suggested that initially, glycogen served as the primary storage compound. However, with prolonged macronutrient stress, there was a shift of the carbon flux towards favoring PHB synthesis. Overall, it was demonstrated for the first time the feasibility of using a phototrophic microbiome to continuous production of PHB in a non-sterile system, contributing to advancing in the field of biopolymer production and offering valuable insights into the metabolic pathways involved.
