When it is no longer possible to maintain, reuse, or remanufacture our assets or products, we work with various vendors to identify economically viable recycling opportunities.
At our Houston Technology Center, for example, drill bits that have reached their end of life are recycled. Most drill bits are made of tungsten carbide matrix material that can be pulverized, decontaminated, and resintered to make new bits. Up to 30% of the consumed matrix powder can come from recycled materials, and this has enabled us to reclaim between 150–300 metric tons of scrap drill bits per year.
