The increasing pressure of urbanization, industrial growth, and rising waste generation has underscored the urgent need for sustainable waste management and alternative energy solutions. Waste to Energy technologies have emerged as a critical response to this dual challenge, offering a method to convert non-recyclable waste materials into usable forms of energy such as electricity, heat, or fuel. Paques is a global leader in biological wastewater treatment and resource recovery solutions, uniquely positioned to bridge the gap between industrial growth and environmental responsibility.
By leveraging its proven biological technologies, Paques transforms high-strength industrial effluents into clean energy and reusable water, turning waste into valuable resources. This approach not only supports India’s transition toward a circular economy but also contributes to its renewable energy ambitions.
Innovating Wastewater Treatment
What truly sets the firm apart in the wastewater treatment industry is its end-to-end innovation journey, from lab-scale discovery to full-scale global deployment. Few companies can claim the ability to develop, test, commercialize, and implement technologies across such a broad industrial spectrum. Paques’s hallmark lies in its biologically precise, energy-efficient anaerobic treatment systems, like the renowned BIOPAQ series, which remove up to 90 percent of pollutants while generating renewable biogas.
With a modular design philosophy, the company solutions seamlessly integrate into both new and existing infrastructure. Backed by nearly 50 years of continuous R&D investment, the company’s commitment to engineering ensures future-ready systems that deliver both environmental and economic value.
“We don’t see wastewater as waste, it’s a source of valuable resources waiting to be recovered. Using advanced biological and chemical engineering, we recover vital resources such as biogas for renewable energy, phosphates and nitrogen for fertilizers, and even rare metals from industrial effluents”, speaks Sudeep, Managing Director, Paques. Paques is a global pioneer in sustainable wastewater and gas treatment, offering patented technologies like ANAMMOX and THIOPAQ that reduce environmental impact and energy use by up to 90 percent.
Its anaerobic systems also generate renewable biogas. ANAMMOX, launched in 2002, is now the world’s leading nitrogen removal system, treating over 160,000 kg of nitrogen daily from sources like municipal wastewater and sludge, showcasing Paques’s commitment to innovation and environmental sustainability. Every installation becomes a net energy generator, helping industries reduce their carbon footprint, achieve water reuse, minimize sludge, and promote true circularity, making sustainability not just a goal, but a built-in outcome.
Driving Circularity
The company’s technologies play a transformative role in water and resource management across industries like food & beverage, pulp & paper, and chemical sectors that account for over 80 percent of the global installations. These industries generate high-strength organic wastewater due to their agrarian raw materials. Paques's anaerobic systems efficiently convert these organic loads into biogas while purifying water, drastically reducing water consumption, by up to 50 percent in breweries and up to 80 percent in pulp and paper mills. In chemical industries, the firm’s precision-engineered solutions remove complex compounds, enabling safe water reuse and preventing environmental contamination.
The company circularity is at the heart of the mission, transforming lin¬ear wastewater treatment into regenerative systems that recover water, energy, and raw materials. The company closes the loop by converting industrial effluents into reusable water, biogas, and fertilizers, reducing reliance on virgin resources and fossil fuels. Looking ahead, Paques aims to double its impact by 2028, focusing on water-stressed, high-growth regions like India, the Middle East, and Africa.
This expansion is driven by modular, plug-and-play solutions tailored for MSMEs, and backed by its strong Make in India manufacturing base. The company is also integrating AI, real-time digital monitoring, and global green innovations to make advanced circular technologies both scalable and accessible for a wider industrial audience. By redefining waste as a resource, Paques is paving the way for a sustainable industrial trans¬formation, where environmental responsibility and economic growth go hand-in-hand.
