Minimizing and managing waste from our operations has been an ongoing commitment within Noble Energy. We reported our waste management performance data for the first time in 2015.
Note that our 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 2016, Noble Energy did not conduct international transport of hazardous waste other than as noted below.
In our U.S. onshore operations, we generated the following amounts of waste:
- DJ Basin: Contaminated soil - 2,410 tons; non-water drilling - 64,420 gallons; drill cuttings - 1,380 tons; misc. oilfield - 22 tons
- Marcellus Shale: General solid - 62 tons; contaminated soil - 1,761 tons; synthetic liner - 57 tons; waste water treatment sludge - 180 tons
- Texas: Will begin data reporting in 2017
In our offshore operations, we generated the following amounts of waste:
- U.S. Gulf of Mexico: Solid - 160 tons; hazardous - 5 tons; operational - 35 tons; naturally occurring radioactive waste - 11.7 tons; waste oil recycled - 52 tons; acid batteries - 1 ton
- Eastern Mediterranean: Israel hazardous: 1,185 tons; non-hazardous: 518 tons. Cyprus – general - 9 tons; dangerous waste (expired chemicals) - 3 tons
- Equatorial Guinea: Operational - 304 tons; general solid - 3 tons; general recycled - 117 tons; waste oil recycled - 3,400 liters. Some waste was shipped to a facility in Texas for recycling
- Falklands: (Waste disposed in 2016 following 2015 drilling) 138.06 tons of waste, of which 82.6 tons (59.8%) was recycled (i.e., metal: scrap metal/aluminum and plastics). Because local disposal/recycling facilities were limited, waste was shipped to the U.K., which required Scottish Environmental Protection Agency (SEPA) approval in 1Q16. 44.08 tons (31.9%) was classified as hazardous.
In our Houston offices, 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 2016, we recycled 1 ton of E-waste.
