Bioplastics

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

Types of Step-Growth Polymers: Polyesters

Types of Step-Growth Polymers: Polyesters

The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...

Microbial Bioremediation of Plastics

Microbial Bioremediation of Plastics

Polyethylene terephthalate (PET) is a synthetic polymer widely utilized in the packaging industry, particularly for bottles and containers. Due to its chemical stability and durability, PET accumulates in the environment, contributing significantly to plastic pollution. It comprises repeating units of terephthalic acid and ethylene glycol, resulting in a semi-crystalline structure that is resistant to natural degradation processes.A notable breakthrough in plastic biodegradation came with the...

Production of Organic Acids

Production of Organic Acids

Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

Production of Pharmaceuticals

Production of Pharmaceuticals

Industrial insulin production uses genetically engineered E. coli expressing a proinsulin gene controlled by a tryptophan promoter and containing a methionine linker for later cleavage. The cells also carry ampicillin resistance for selective growth. Seed cultures are stored at −80 °C and production begins by thawing a small amount to inoculate starter cultures, which are progressively scaled to a 50,000-L bioreactor. In the bioreactor, E. coli grow in nutrient-rich media under sterile, tightly...

Background:

The plastics industry seeks cost-competitive, sustainable alternatives to petroleum-derived polymers.
Biomass-derived materials, such as starch and albumen, present a promising renewable resource.
Developing efficient processing methods is crucial for creating viable bioplastics.

Purpose of the Study:

To investigate the feasibility of incorporating starch (corn and potato) into albumen/glycerol formulations for bioplastic production.
To evaluate the effects of varying starch concentrations (0-30 wt.%) and processing methods (thermo-plastic vs. thermo-mechanical) on material properties.
To assess the potential of albumen/starch bioplastics as a biodegradable alternative for the plastics industry.

Main Methods:

Preparation of albumen/starch-based bioplastics with varying starch content (0-30 wt.%).
Utilized thermo-plastic and thermo-mechanical processing techniques.
Characterization using transmittance measurements, Differential Scanning Calorimetry (DSC), Dynamic Mechanical Thermal Analysis (DMTA), and tensile testing.

Main Results:

Starch concentration significantly influenced the optical and tensile properties of the bioplastics.
Dynamic Mechanical Thermal Analysis (DMTA) at low deformation showed minimal sensitivity to starch addition.
Thermo-mechanical processing resulted in transparent albumen/starch materials.
Materials processed via thermo-mechanical methods exhibited tensile strength comparable to commodity plastics at low deformation.

Conclusions:

Albumen/starch bioplastics can be cost-effectively produced using thermo-mechanical processing.
These bioplastics demonstrate tunable optical and mechanical properties based on starch content.
Albumen-based biopolymers show potential as a biodegradable substitute for conventional oil-derived plastics in applications like transparent packaging.
