Minimizing and managing waste from our operations has been an ongoing commitment within Noble Energy. In 2015, we improved our data collection processes so that we now disclose waste management performance data in our report for the first time.
In 2015, we generated 88,046 tons of waste from our operations in the DJ Basin, Marcellus, Gulf of Mexico, Cameroon, Equatorial Guinea, Cyprus and the Falkland Islands. (Quantitative data was not gathered for our recently acquired onshore Texas operations.) Waste items included contaminated soil, construction demolition materials, waste oil, drill cuttings, drilling fluid/mud, and other general operational waste.* Products are sold and removed via truck or pipeline. We do not package our product for sale, so there are no packaging materials to reclaim and none of the product comes back for recovery. In 2015, Noble Energy did not conduct international transport of hazardous waste.
We recycled 109 tons of waste from our operations in Equatorial Guinea and Cyprus and our offices in Houston and Denver. Recycled materials included waste oil, construction materials, e-waste and other general operational waste.
In Israel, we are still refining our data collection. Many of the actions we take in that country to reduce wastes apply across other operations as well:
- Separate recyclable drinking bottles and cans from domestic waste
- Separate recyclable plastic
- Recycle used gas calibration cylinders (content reclaimed and metal reused)
- Check expired or unneeded chemicals before disposing to see if they can be reused or recycled by other organizations
- Recycle used oils
- Shred and separate metal filters used in equipment (metal is recycled, oils are reused, paper is disposed of)
*Amounts of drilling waste (mud and cuttings) — DJ Basin (non-water drilling): 5,130 gallons; Cameroon (drilling waste): 41 tons; Marcellus (drilling fluid mud): 16,377 tons, (drill cuttings): 37,293 tons; Falkland Islands (drilling fluids): 1,081 tons, (drill cuttings): 2,607 tons
We use a Houston-based electronics recycler to handle electronic waste. E-waste is the most rapidly growing segment of municipal solid waste streams and contains valuable, recoverable materials as well as limited quantities of hazardous materials. Our vendor is R2 certified, the electronics recycling industry’s leading certification to ensure quality, transparency and environmental and social responsibility. In 2015, we recycled over 6,000 pounds of miscellaneous electronics.
