The Bechtel Report 2016

Reducing Environmental Footprints

A circular economy is an industrial system that produces little to no waste or greenhouse gases by design or intention. Many of Bechtel’s projects around the world are their own small-scale circular economies. One example with which Bechtel is involved is the South Caucasus Pipeline Expansion (SCPX) project, a 303-mile (488-kilometer) pipeline that extends the South Caucasus pipeline alongside the existing Baku-Tbilisi-Ceyhan pipeline through Azerbaijan and Georgia to Turkey. The Bechtel-Enka Joint Venture (BEJV) is building compressor stations, a metering and pressure-reduction station, and some roadways for the pipeline.

“Zero-waste targets should always be the goal. Soon all projects will have an approach that facilitates achieving this target or getting as close as possible.”

Mohammad Orfi Environmental and social lead, Bechtel

South Caucasus Pipeline Expansion, Republic of Georgia

A large amount of inert construction waste including—excavated rock, wood pieces, metal scraps, and food—is generated during construction and at workers’ camps and associated facilities. The BEJV team and our customer, South Caucasus Pipeline Company Limited, operated by BP, are using a mix of design, material procurement, and technology to soften the project’s environmental footprint. This approach includes:

  • Waste-handling areas that store, segregate, and process waste for reuse and recycling
  • Waste compression machines that decrease volumes of waste
  • Food dryer and biomass technology that treat organic waste and convert it into biodegradable ash and thermal energy to heat water
  • Sewage treatment plant that re-treats and recycles water, including treating and discharging wastewater for dust control on access roads
  • Sustainable procurement practices to purchase local goods in bulk, minimize packaging amounts, reduce the environmental impact and waste generation, and maximize durability and reparability of goods and equipment

These are among actions that cut waste volume, convert material for reuse, recycle water, and heat camp facilities.

Closing the Loop on Project Waste Streams

1

Source materials locally Decrease delivery distances, associated vehicle fuel use, and carbon emissions while promoting local economic benefits

2

Condense waste Reduce waste transported to landfills, and in doing so, decrease vehicle fuel use and carbon emissions

3

Convert waste into clean energy Operate a biomass dryer and incinerator to convert food waste into thermal energy, thereby decreasing the use of diesel generators

4

Recover treated water Operate a sewage treatment plant to recover and reuse treated water; release excess treated water for local community use

5

Reuse materials locally Donate surplus construction materials, associated vehicle fuel use, and carbon emissions while promoting local econonomic benefits

SCPX Circular Economy & Impact

Fuel:

Saved an average of 371,316 gallons (1.4 million liters) per year, which equates to removing nearly 700 cars from the road

Carbon emissions:

Prevented an average of 3,300 metric tons of emissions per year

Water:

Conserved an average of 100,000 gallons (378,541 liters) a year, enough to fill 1 million 12-ounce (.35-liter) water bottles

Food Waste:

Reduced 90 percent (990 kg/work day), equal to about 730,000 pounds, or 365 tons, of waste on average per year

Construction waste:

Recovered, reused, and recycled 40 percent annually

Achieving sustainability excellence

In 2015, the U.S. Department of Energy recognized three Bechtel-affiliated sites with five sustainability awards for driving improvements to reduce waste, water use, energy, and pollution. The three sites were: Lawrence Livermore National Laboratory, Los Alamos National Laboratory, and the Y-12 National Security Complex.

Changing how we deliver

Bechtel uses Data-centric execution to drive efficiency, cost savings, and sustainability in materials management. For example, an energy project can easily have as many as 20,000 drawings of three-dimensional designs that are each printed and processed separately. By transferring plans and drawings to key suppliers digitally, instead of on paper, we can reduce waste by up to 90 percent.

Reducing our footprint

We continue to collect information on greenhouse gas emissions and water consumption resulting from our major offices. Our approach at these offices1 focuses on reducing energy consumption and implementing energy-efficient programs. In our London office on Pilgrim Street, LED light fittings contribute annual energy savings of more than $6,200 per floor.

  • Sum of Total Scope 1 Emissions (tCO2eq)
  • Sum of Total Scope 2 Emissions (tCO2eq)
  • Revenue Intensity (tCO2eq/billion USD)

Since 2011, as a result of careful monitoring and implementing sustainability programs among our offices, we have reduced our carbon emissions by 15 percent and our revenue intensity (greenhouse gas emissions per billion dollars in revenue) by 16 percent.

Water consumption reported by 9 of the 15 major offices was 34.2 million gallons (129.5 million liters)—down by 13 percent since 2013—equivalent to 5 million gallons (19 million liters).2

1 Due to the nature of our business, we stay flexible on the number of offices that are included each year in the report. Some offices are merged with others or are closed. For 2015, we selected 15 major offices to report on scope 1 (direct emission from boilers and furnaces) and scope 2 (indirect emissions from electricity). Offices are selected based on average office population throughout the year. We base our carbon footprint accounting on the Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard.

2 In 2013, 11 of our 18 reporting offices consumed 27.7 million gallons (104.9 million liters) of water. In 2014, 10 of our 17 reporting offices consumed 36.2 million gallons (137 million liters) of water. Water consumption data are collected from offices that have the ability to track it.
