Our Initiative and Impact

As a common good, water is a shared natural resource and we believe that the smallest of efforts add up to make a huge difference. At Glenmark our intention is to improve water management by focusing on optimization, reuse and recycle of this resource.

Believing in the principle of 3R’s, we have made efforts to reduce our water consumption by adopting best practices, alternatively reusing and recycling the treated wastewater in cooling towers, boilers and landscaping.

Our freshwater consumption for utilities, domestic and gardening has reduced over the years with increase in process water consumption. We have invested in Rain Water Harvesting (RWH) structures in our facilities at Goa, Indore, Nalagarh, Baddi, Taloja and Mahape. The total capacity of our RWH structures can replenish 10 percent of our annual freshwater demand.


One of the most promising efforts that stem from the global water crisis is reclamation and recycling of industrial and municipal water. In the context of increased fresh water demand for industries, wastewater treatment and recycling requires greater focus. We understand that ‘wastewater is a resource’ that can be adequately treated to successfully satisfy most water demands, simultaneously achieving pollution prevention and reduction in wastewater discharges.

We have adopted Zero Liquid Discharge (ZLD) approach in our Aurangabad and Sikkim plant. Good quality water is reclaimed from wastewater at this facility and is available for recycle in boilers, cooling towers and toilets. In rest of our facilities wastewater is treated and recycled for gardening purposes within our premises. These efforts help us meet 38 percent of annual freshwater needs.

The world over, governments are urging industry to switch to renewables. Today, many countries and corporations rely on wind and solar to power their needs. Our operations today incorporate innovative systems, processes and products designed to optimize use of energy. In many cases we have made a conscious shift to utilize energy from renewable sources.


Our operations today incorporate innovative systems, processes and products designed to optimize use of energy. We have implemented a number of initiatives to reduce consumption. We introduced new and innovative interventions in the areas of lighting, pumps and motors, power factor, automation, refrigeration system and fuel. In many cases we have made a conscious shift to utilize energy from renewable sources.

Our facilities run on diverse energy sources of renewable and non-renewable nature. Biodiesel is used at our Aurangabad and Nashik facilities. Baddi and Nalagarh rely on a mix of Liquified Petroleum Gas and HSD and remaining facilities at Sikkim, Goa & Indore are using HSD/LDO.

Efforts in conserving and efficiently using energy and fuels have positively impacted our contribution to the local air quality and climate change. A key enabling factor has been the drive from employees who have been instrumental in implementing these initiatives.

The amount of waste produced worldwide is 4 billion metric tonnes each year and expected to double by 2025 owing to economic and population growth. About 70 percent of this is dumped into landfills or open dumps. Each type of waste creates different hazards, adversely impacting the health of communities and ecosystems alike.

Our strategy is to handle each stream of waste with specific solutions, thus managing and disposing waste with minimum impact. We have focused on four waste streams including hazardous waste, non-hazardous waste, e-waste and domestic waste from our facilities.


At Glenmark we pursue best in industry practices for disposal of hazardous waste.

Our target is to reduce the waste generated and to devise innovative ideas to send zero hazardous waste in to the landfill. We have initiated this process by co-processing the Hazardous waste. Our plants like Goa, Indore, Baddi, Sikkim, Nalagarh are engaged in Pre-processing & Co-processing of Hazardous waste and aiming to achieve 100% disposal of Hazardous waste through cement kilns.


Glenmark understands the importance of segregation of waste at source. By doing so, we not only salvage valuable material present in the waste but also divert this waste from going into landfills. It also helps reduce greenhouse gas emissions that are otherwise emitted if not composted. In our facilities, segregated waste is converted into manure via vermicomposting.



We at Glenmark understand the importance of conserving virgin natural resources and our commitment towards this cause is evident from the numerous initiatives that we have undertaken. Our offices are a constant source of waste, especially e-waste We have reduced the amount of e-waste going to landfills by encouraging refurbishment and reuse of electronic components.

While e-waste has been a source of livelihood for the urban poor, it is often one of the major contributing factors for severe risks to human health and the environment. Most workers engaged in the waste sector are not aware of the risks involved. The practices adopted in recycling waste and recovering materials are rudimentary, involving acid bath heating, open burning and indiscriminate use of chemicals without following any safety norms. These are often conducted in the by lanes of the city, making them dangerous and hazardous for the environment and human health.

By sending the e-waste to authorised recyclers we are assured of safe disposal of the e-waste generated in our offices, plants and R&D sites, thereby reducing the environmental pollution and health risks to the society.

We at Glenmark have promoted resource efficiency through waste management in an environmentally safe and socially responsible manner by adopting a combination of treatment options. These include e-waste recycling, in-house composting, hazardous waste co-processing, coupled with creating awareness through various environmental campaigns.



Scarcity of resources is driving the need for efficient use. Our commitment to conserving natural resources includes making best use of all materials. At Glenmark, we recover the solvent used in our processes for material efficiency and resource recovery. Pharmaceutical processes require solvent as a medium for separation and purification, washing of product and cleaning of equipment. Significant quantity of the spent solvent is generated from these processes. Such a large volume of spent solvent cannot be reused without decontamination.

Solvent recycling in API facilities is possible after quality assurance unlike other manufacturing facilities that strictly avoid recycling of materials. Spent solvent disposal to the environment is not advised as it can be toxic and non-biodegradable. Recovering good quality solvent for recycling in API manufacturing process is also a challenge as it requires complex design and large set up to remove various contaminants present in the spent solvent.

We have been strengthening our ESG focused approach by committing to external initiatives and taking proactive measures. Our ESG strategy is aligned with the UN SDGs and aims to enhance our contribution to the global sustainable development agenda. We have also been communicating with our stakeholders on our ESG performance through GRI standards aligned sustainability reports annually.

Our ESG centric approach has also been recognised by globally acclaimed benchmarks such as the Dow Jones Sustainability Index (DJSI). The acronym “ACE” captures the essence and key facets of our ESG strategy. It is our vision to drive tangible ESG impact and work towards developing programs that help us emerge as a global benchmark.

We have conducted the supplier assessment through third party auditors on the basis of Glenmark supplier sustainability protocol in which there is an audit tool with rating system. Assessments of 7 suppliers were conducted by third party auditors and almost 1200 suppliers were covered by self-assessment using the audit tool and on the basis of their response, they were rated as “Beginner”, “Implementer” or “Stewardship”.

Suppliers / Vendors gets audited on the elements like

a. Ethical responsibility,
b. Environmental Responsibility,
c. Social Responsibility
