Aurapha Private Limited
-is a biotechnology-driven company dedicated to transforming agro-industrial waste into sustainable, high-value products. We specialize in the conversion of spent silkworm pupae, a largely underutilized byproduct of the silk industry into eco-friendly innovations such as bioplastics (Polyhydroxyalkanoates or PHA), animal feed proteins, controlled-release fertilizers, and biodegradable cosmetic ingredients.
At Aurapha, we believe that waste is a resource waiting to be reimagined. Our patented processes extract oil, protein, and chitin from silkworm pupae using advanced fermentation and purification technologies. This oil serves as a low-cost, renewable carbon source for producing PHAs - biodegradable and biocompatible polymers that can replace traditional plastics across multiple sectors, including aquaculture, agriculture, cosmetics, and single-use consumer goods.
Towards a Green Future
Our mission is to create circular, science-based solutions that address global challenges like plastic pollution, antimicrobial resistance, and agricultural inefficiency. Through continuous R&D, we’ve developed a high-yield, high-cell-density fermentation platform that enables cost-effective, scalable production of PHAs tailored to diverse applications—from fish feed additives to cosmetic microbeads.
With every innovation, Aurapha is committed to sustainability, social impact, and ecological responsibility. By turning industrial waste into biodegradable materials, we are not only creating value but also paving the way for a greener, cleaner future.
What is PHA?
Polyhydroxyalkanoates or Biodegradable PHA plastics, are eco-friendly polymers produced through the natural fermentation of sugars or lipids by bacteria. These bioplastics are made up of polyesters synthesized from R-hydroxyalkanoic acids, offering a sustainable alternative to conventional plastics.
Polyhydroxyalkanoates (PHAs) are a versatile class of biodegradable bioplastics with melting points ranging from 40°C to 180°C, depending on their composition. These polymers are known for their excellent resistance to ultraviolet (UV) radiation and strong water barrier properties, making them suitable for demanding applications. PHAs are soluble in halogenated solvents like chloroform, dichloromethane, and dichloroethane, which facilitates their processing and formulation.
To enhance their mechanical strength, flexibility, and processability, PHAs can be blended with multifunctional additives or high-valency compounds. Their non-toxic nature makes them particularly attractive for food packaging and biomedical applications.
Unlike conventional plastics with fixed structures, PHA represents a diverse family of polymers whose properties can be tailored by altering the monomer composition and fermentation conditions. PHAs can be synthesized as homopolymers, composed of a single monomer, or as copolymers, incorporating multiple monomers to achieve improved flexibility, toughness, and functionality. While homopolymers may have limited mechanical performance, their properties can be enhanced through plasticizers or blending with other biocompatible materials.
