Sustainability & Social Responsibility

Our sustainability journey is geared towards creating lasting value for all our stakeholders - shareholders, employees, partners and society – without a trade-off on their mutual or individual interests. The processes that we deploy focus on eliminating waste and conserving natural resources like energy and water. All our plants are 'zero liquid discharge' facilities, which means that all the liquid waste and effluent they generate is treated within their premises and reused. We also co-processed/recycled 91 % of our total hazardous waste and continue to be on course to meet our target of zero hazardous waste to landfill by 2020.

Realizing our responsibility to the people of the communities that we live and work in, we pursue community care with the same efficiency and meticulousness with which we pursue our business to create real opportunities, building capabilities and empowering those who need them in areas of health, education and livelihoods.

We are here to help, if you have any country specific requirements.

An active pharmaceutical ingredient is defined in ICH Q7 as “any substance or mixture of substances intended to be used in the manufacture of a drug product and that, when used in the production of a drug, becomes an active ingredient in the drug product. Such substances are intended to furnish pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment or prevention of disease or to affect the structure and function of the body.”

API manufacturers are expected to apply CGMPs to the API process beginning with the use of starting materials, and to validate critical process steps that impact the quality and purity of the final API. Controls over material quality are expected to increase as the process approaches the final API. The level of control needed is highly dependent on the manufacturing process and increases throughout the process as it proceeds from early intermediate steps to final isolation and purification steps. The appropriate level of control depends on the risk or criticality associated with each specific process step.
An API process is a related series of operations which result in the preparation of an active pharmaceutical ingredient. Major operations or steps in an API process may include multi-step chemical synthesis and fermentation, purification, crystallization, drying, milling, packing, labelling, and testing. The final API the progresses towards appropriate characterization and analytical techniques.

Each country will have its regulatory authority that continuously monitors the drug development process, licensing, registrations, marketing, and labelling of the products. Some of the notable regulatory bodies are as follows: USFDA(USA), MHRA(UK), TGA(Australia), CDSCO(India), etc.
The quality of APIs has a significant effect on the efficacy and the safety of medications. Poorly manufactured or adulterated APIs are associated with health issues, illness, or death. So, to ensure the quality and prevent the defects of APIs, regulatory bodies impose stringent rules & screen the APIs thoroughly to ensure medication quality as per the regulatory standards. Violating any of these regulatory standards or procedures can result in huge fines.

The global API market size is expected to reach USD 247.3 billion by 2025 from USD 185.3 billion in 2020, at a CAGR of 5.7%. Market growth will be steered by factors such as rising drug R&D, chronic diseases, the demand for generics, and the increasing uptake of biopharmaceuticals.
