Our industries
Food, Beverage & Dairy
Water plays a vital role in the food and beverage industry, especially in the CIS region where sustainability, compliance, and resource efficiency are increasingly critical. Nijhuis Saur Industries supports the region’s leading producers with advanced solutions to reduce water consumption, reuse treated process water, and recover valuable resources such as energy, heat, and organic fertilizer. By turning environmental challenges into opportunities, we help clients lower operating costs, meet strict regulatory requirements, and enhance circularity across their operations.
Our expertise spans across the full food and beverage spectrum—from soft drinks and dairy to poultry, meat, and agricultural processing. With a strong track record in designing and delivering complete wastewater treatment and resource recovery systems, NSI brings global experience and local execution to drive sustainable transformation in the region’s most water-intensive industries.
Poultry
The poultry industry in the CIS region generates large volumes of wastewater and organic by-products that require careful treatment and resource management. Nijhuis Saur Industries offers integrated solutions to recover valuable resources from slaughterhouse and processing operations, including biofuel, animal fat, fertilizers, energy, heat, and clean water. Our sustainable approach helps poultry producers meet strict environmental regulations, reduce operational costs, and align with international sustainability standards, all while supporting efficient and compliant (poultry) processing operations.
The mining sector plays a vital role in the economies of CIS countries such as Kazakhstan, Uzbekistan, and those in the Caucasus, but it presents major water-related challenges—from managing tailings and process water to meeting strict environmental discharge standards. Nijhuis Saur Industries supports mining operations across the region with smart, sustainable water and wastewater solutions. We deliver advanced treatment systems for removing heavy metals, PFAS, and other pollutants; enable water reuse to reduce freshwater intake; and offer modular, mobile units ideal for remote sites. Our 4R approach—Reduce, Remove, Reuse, Recover; helps clients minimize environmental impact, optimize operations, and recover valuable resources from their effluent streams.
Power Plants
The power (energy) industry in the CIS region relies heavily on water for critical operations like cooling, steam production, and effluent handling. Nijhuis Saur Industries delivers bespoke water treatment systems to demineralize boiler-feedwater, remove pollutants, reuse treated effluent, and recover energy & heat; all in compliance with strict environmental and safety standards. Leveraging our end-to-end FEED-to-execution capabilities, digital monitoring, and modular/mobile solutions, we help power producers reduce ecological impact, optimize costs, and bolster plant reliability.
Oil & Gas
The oil and gas industry in the CIS region faces complex water and wastewater challenges, from treating high salinity produced water to meeting strict discharge regulations. Nijhuis Saur Industries delivers advanced, reliable solutions for upstream and downstream operations; offering systems for oil-water separation, produced water reuse, and the removal of contaminants such as hydrocarbons, heavy metals, and solids. With modular and mobile units, digital control, and a focus on sustainability, we help oil and gas operators reduce environmental impact, ensure compliance, and optimize water management across the entire production cycle.
