Zero Facility Wastewater Discharge into the Columbia River

NWIW is proud to be the first industrial company along the Columbia River to invest in Zero Liquid Discharge (ZLD) technology which recycles and reuses the water used at the NWIW facility. The ZLD system eliminates facility wastewater discharge into the Columbia River, removing potential impact on the river water and the aquatic life that depends on it.

Reducing greenhouse gas emissions across the globe

World leaders are working to reduce coal consumption over the next decade in order to eliminate chronic air pollutants and address concerns about climate change. Worldwide demand for goods produced in Asia is growing, including those with petroleum or coal-based inputs, creating a need for a cleaner source to meet that demand. Replacing oil and coal-based methanol with methanol made from natural gas to produce olefins reduces carbon dioxide emissions by as much as 70%. Combined with ultra-low emission technology, emissions can be reduced by up to 90%. 

INNOVATIVE TECHNOLOGIES REDUCES EMISSIONS AND PROTECTS OUR ENVIRONMENT

Ultra-low Emissions (ULE) Reforming Technology

NWIW will use an ULE reforming technology that converts natural gas to methanol by using a combination of electricity and process-generated heat to power production. Using natural gas and our ULE technology reduces coal consumption and allows for a cleaner method of methanol manufacturing. Although ULE technology has been used at sites around the world since 1994, NWIW will be the first to use this clean technology for methanol production in the United States.

Zero Liquid Discharge (ZLD) Technology

NWIW will implement ZLD technology at the proposed Kalama facility. ZLD technology eliminates all water discharge into the Columbia River, eliminating impacts on aquatic life. It uses a combination of technologies that will remove contaminants from the wastewater stream. The wastewater can then be recycled and reused during the production process.

BEYOND ENVIRONMENTAL COMPLIANCE

Each proposed NWIW facility is subject to formal environmental review and must adhere to local, state, and federal standards. At NWIW, we go beyond environmental compliance, implementing innovative technologies to increase the energy efficiency of our operations. NWIW is committed to environmental sustainability and we will continue to explore new ways to reduce waste and reuse byproducts of methanol production.

Additional environmental information can be found on the project summary. Environmental information for the Kalama SEPA process is available at the DEIS website.
