Our Initiative and Impact

Water Management

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.

Wastewater Management

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 five of our plants at Ankleshwar, Aurangabad, Dahej, Mohol and Kurkumbh. Good quality water is reclaimed from wastewater at these facilities 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. 

Energy Efficiency

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.

Energy Consumption and Efficiency

In order to address increasing energy demand owing to our production expansion 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. 

Some of our energy saving initiatives:
  • Energy efficient lighting system which includes optimum number of lamps on the shop floor, installation of LEDs, individual switches for each lamp, motion sensors and timers to switch off the lights during dormant periods
  • Energy efficient Heating, ventilating, and air conditioning (HVAC) system, which includes optimized blower speeds providing required number of air changes per hour, temperature controller and timer on ACs and exhaust fans
  • Enhanced heat recovery and efficient chilling systems
  • Steam condensate recovery and reuse in boiler operations
  • Installation of new electrical panel to improve power factor
  • 94 hours of employee training on energy conservation and greenhouse gas (GHG) management

We have made installation of energy efficient equipment as a standard practice for all the new facilities and have adopted a phased approach for replacement of the existing machinery.

Our efforts in energy efficiency have resulted in saving energy thereby providing electricity for 70,100 rural households for one year.

Fuel Use and Conservation

Our facilities run on diverse energy sources of renewable and non-renewable nature. High Speed Diesel (HSD) is used across our 15 facilities whereas biodiesel is used at our Aurangabad, Nashik, Mohol and Kurkumbh facilities. Facilities at Dahej, Ankleshwar, Aurangabad rely on a mix of natural gas and HSD.

Efforts in conserving and efficiently using energy 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.

Waste Management

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.

Hazardous Waste and Co-processing

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 where the hazardous waste can be used as a resource. We have initiated this process by co-processing the off-specification/ expired medicines in cement kilns.

Domestic Waste

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 and paper. 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.


Management of waste solvent

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.
