• Waste Management

    NOV is in the process of transitioning to a proactive model of minimizing waste throughout all facilities. Over the last few years, many NOV facilities have implemented programs to reduce the amount of regulated waste generated by identifying areas for process optimizations and changing materials used in operations. These waste management programs are guided by NOV’s efforts for sustainable practices and are also in compliance with regulatory requirements and the cost of disposal that NOV has previously incurred. Regulations and laws governing waste management, disposal, and volumes are identified in the regions in which we operate and NOV maintains compliance with these obligations. Specific governing agencies and regulations include Superfund Amendments and Reauthorization Act (SARA) Title II annual waste reporting, National Pollutant Release Inventory (NPRI), and Registration, Evaluation, Authorization, and Restriction of Chemical Substances (REACH), which all necessitate monitoring and documentation of proper storage and disposal of chemicals and wastes at our facilities. Some of the regulations are state-, city-, or region-specific. For example, if a facility is categorized by the EPA as a “Large Quantity Generator” or is a facility that reports a “Toxic Release Inventory (TRI) Form R” chemical in the state of Texas, the facility must produce a Source Reduction/Waste Minimization Plan. These plans outline a 10% reduction within a five-year period and NOV continues to meet these requirements.

    To reduce the amount of regulated waste generated, NOV has actively researched and implemented materials that are less hazardous to employees and the environment. In doing so, many facilities have changed from oil-based to water-based solvents.

    Many technologies have also been implemented to reduce waste and emissions. At several facilities, NOV has installed Regenerative Thermal Oxidizers (RTOs), which are used as Volatile Organic Compounds (VOCs) emission control systems. The RTOs are essential to reducing volatile organic constituents and reducing NOV’s overall waste.

    To manage trash, NOV has encouraged and implemented good housekeeping practices, proper storage and containment designs, and recycling streams for solvents, scraps, and paper throughout our facilities. Several NOV facilities have implemented recycling programs that also collect plastics, aluminum cans, cardboards, and other recyclables.

    To protect employees, meet legal obligations, and encourage sustainable practices, training and support is provided on a regular basis by Corporate HSE, the Environmental Risk Group, and the Business Unit HSE Groups to the operations that fall under waste reporting regulations. As a global company, NOV is continuing to expand the recycling and minimization efforts among our facilities and will be developing and refining the tracking methodology for minimization of several types of waste. NOV’s HSE Management System is moving to support waste minimization efforts through electronic benchmarking, measuring, tracking progress, and reporting. Ultimately, NOV will manage all waste information and chemical inventories through our Environmental Management System (EMS) to support our global reporting efforts and requirements.
