Metals production relies heavily upon efficiencies which allow for a market-ready commodity to keep an ever-changing world building and growing. WesTech process equipment provides key links in this supply chain, assuring both environmental stewardship and maximized production.
While land-based industry has been subject to strenuous emissions regulations over the past decades, air emissions from sea-going ships’ machinery has so far been largely unregulated. As a result, according to EU statistics, ships have become the single biggest source of sulphur dioxide (SO2) within the EU. The US EPA (US Environmental Protection Agency) reports similar findings, i.e., that the proportion of air pollutants released which can be attributed to the shipping industry is increasing. MARPOL Annex...
Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of...
Through the application of modern mining technologies, WesTech helps to assure that the byproducts of minerals extraction process are made inert, reliably contained and kept from causing environmental damage. Implementation of WesTech tailings processing technology assures protection of the groundwater, surface waters, wildlife and communities which in the past have been the victims of tailings dam leaks and levy failures.
WesTech designs and manufactures thickeners for the coal prep industry for product concentration, tailings disposal and CCD circuit washing, including HiFlo Thickeners and Deep Bed Paste Thickeners. Paste thickening is a proven technology increasing the profitability of mining operations. In the coal preparation plant there are two applications for paste thickening: concentrating fine coal and producing paste from coal tailings for increased water recovery and elimination of tailings ponding. Paste thickeners...
What is an Environmental Product Declaration? An Environmental Product Declaration (EPD) is a verified (and registered) document that communicates transparent and comparable information about the life cycle environmental performance of your products. Environmental Product Declarations according to ISO 14025 and/or EN 15804 support companies in proving their responsibility for providing relevant product related environmental information.

As operations continue to expand to more and more remote locations, the need for a safe, effective and compliant waste disposal solution for mining companies is clear. At Inciner8, our range of incinerators are perfectly suited to mining waste. In recent years, mining operations have been spreading around the world, with attention turning to a wide range of raw materials – including cobalt, uranium and titanium. But as mining has increased, so too have the regulations around it. To comply with strict...
Eco-Tec acid purification unit (APU) eliminates the practice of dumping or bleeding different types of acid which is contaminated with dissolved metals and solids during pickling, etching and forming. Continuous purification of acids provides significant cost savings. Additionally, benefits also arise in the areas of environmental compliance, increased productivity, improved product quality, and better safety conditions.
What is a Product Environmental Footprint (PEF)? The European Commission launched the Environmental Footprinting initiative, also known as the Single Market for Green Products. It is designed to harmonize the many different methodologies available to calculate and communicate environmental information.

Before natural gas or oil is transported through new pipelines, the entire length of the pipeline assembly is pressure tested using either fresh water or seawater, and is the final construction ‘quality assurance’ test before the pipeline is put into operation. The pressure test is held for a specific amount of time, from between 1 day and 100 days, to ensure structural integrity before the pipeline is placed into operation.
