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...
Biological Treatment of Effluent and Waste Water01:30

Biological Treatment of Effluent and Waste Water

Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...

Area of Science:

  • Animal Science
  • Biotechnology
  • Waste Management

Background:

  • Shrimp processing generates significant waste, primarily from shrimp heads.
  • Chitosan, derived from chitin in shrimp shells, has various industrial applications.
  • Valorizing chitosan processing waste offers a sustainable alternative to disposal.

Purpose of the Study:

  • To evaluate the nutritional composition of waste generated during chitosan production from shrimp heads.
  • To determine the potential of this waste as a premix ingredient for improving laying chicken production performance.

Main Methods:

  • Shrimp head waste was processed into chitosan via demineralization, deproteination, and deacetylation.
  • Liquid wastes from each step and a neutral mixture were analyzed for nutrient and amino acid content.
  • Chemicals used included NaOH, hydrochloric acid, Na2SeO3, and NaCl solutions.

Main Results:

  • The liquid wastes and neutral mixture were low in energy, protein, and fat.
  • These waste streams were found to be rich in essential minerals.
  • Deproteination wastewater and the neutral mixture exhibited the most abundant and complete amino acid profiles.

Conclusions:

  • Chitosan processing waste from shrimp heads contains essential minerals and amino acids beneficial for livestock.
  • This waste demonstrates significant potential for use as a cost-effective and sustainable premix in animal feed.
  • Utilizing this waste can improve the overall production performance of laying chickens.
