“…Bioplastics are biodegradable plastics made from the renewable sources [4]. Renewable sources such as potato starch, corn starch, fibres obtained from pineapple, jute, hemp, banana stems [14,15] cassava [16], newspaper pulp [17], waste paper [18], Prosopis juliflora [19], citrus waste [20], cyanobacteria [21], Pseudomonas putida [22,23], Bacillus sp. [24] Employment of new techniques for manufacturing of bioplastics that promote sustainable solution and reduce the plastic waste has been greatly encouraged in recent years [25].…”

Petrochemical based plastics have been widely used as packaging materials, as they have good barrier properties, stiffness, tensile strength & tear strength. Although in great demand plastics have many disadvantages like very low water vapour transmission rate, non- biodegradability etc. which further causes environmental pollution. Keeping in mind about the pollution and harm caused to the nature, newer concepts about the use of bio-plastics came into force. Bio-plastics are produced from the biological sources such as potato, potato peels, corn, sugarcane, wheat, rice, banana peels etc. These plastics are environment friendly & biodegradable, and are safer option than the petroleum-based plastics. These biodegradable plastics break down into carbon dioxide, water & inorganic compounds and degrade completely. The time-line, sources and other important details about the bio-plastics have been presented in this review paper.

“…The biopolymers are natural polymers designed to undergo significant changes in their chemical structure, by the action of microorganisms present in nature under various environmental conditions. They can come from renewable sources (such as starch and cellulose), synthesized by microorganisms (as reserve substances), chemical synthesis, or obtained from fossil sources such as petroleum [15,2].

“…PHAs according to the number of carbon atoms in the structure are classified into three major classes. These consist of short-chain length hydroxyalkanoic acids (SCL), ranging from 3 to 5 carbon atoms, medium-chain length (MCL) with 6 to 14 carbon atoms, and long-chain length (LCL) with more than 15 carbon atoms [2].…”

“…Industrial production of petroleum-based plastics increased significantly after their introduction to the market over 70 years ago. Plastics have gained tremendous importance precisely because they have highly resistant, inert, versatile, and durable properties [1,2]. However, growing concern about the fossil reserves depletion, price volatility, and the environmental impact of conventional plastics is becoming an increasingly severe problem [3].…”

Degradation of Plastics

High accumulation of generated plastic waste is a growing concern. Alternatively, scientific efforts are underway to drive industrial demand to replace these products with superior quality, adequate biodegradable resources. Cyanobacteria are a versatile group of phototrophic prokaryotes capable of producing polyhydroxyalkanoates (PHAs) using sunlight and carbon dioxide (CO2) as a form of carbon and energy reserve. PHAs are appealing alternatives for traditional chemical plastics because these have to resemble characteristics, biocompatibility, and complete biodegradability. In this sense, this chapter aims to address the potential of cyanobacteria as a biodegradable alternative solution.

“…Various mesophilic and thermophilic cyanobacterial species have been explored for their CO 2 sequestration capabilities in flue gas (Matsumoto et al, 1997; Ono & Cuello, 2006). Moreover, cyanobacteria are powerful, economic, and eco‐friendly alternative for producing biopolymers like polyhydroxyalkanoates which can help in CO 2 mitigation and as well as in waste reduction (Bhati, 2019).…”

Cyanobacteria as a potential bioasset for restoring degraded land

Degradation and pollution of land resources is a severe issue worldwide. Rapid urbanization and increased food demand have necessitated the restoration of degraded and highly contaminated land resources in a sustainable manner. The role of soil microorganism in maintaining nutrient balance, texture, fertility, and soil health is widely acknowledged. Cyanobacteria, one of the major components of soil microbiota, have been explored for their role as biofertilizers in improving plant growth and increasing soil fertility; however, less attention has been paid to their potential in restoring degraded lands. Cyanobacteria aids in nutrient cycling, production of plant growth‐promoting substances, desalination, and degradation of diverse organic as well as inorganic contaminants. They use diverse mechanisms for bioremediation (such as biosorption, bioaccumulation, and biotransformation) of contaminants in addition to the specific mechanism employed. They occur in symbiotic relationships with various hosts in natural as well as anthropogenically disturbed environments. Therefore, their use in restoration of highly degraded lands is justified and needs to be recognized worldwide. Identifying and exploring cyanobacterial species thriving in stress conditions and multiomics approaches would help in reconnoitering the complex plant–soil‐cyanobacteria interactions and enable scientists to design robust and well‐integrated biotechnological tools for soil remediation. Nevertheless, several technical challenges need to be addressed for rendering cyanobacteria as a realistic and viable bioasset. In this article, we summarize the role of cyanobacteria in addressing the reclamation of various types of degraded and polluted soils. And, it also examines the remaining knowledge gaps that limit its applicability in diverse environmental settings in a sustainable manner.
