Mark West is proud to report in the last three years we’ve:

» Decreased wastewater generation per case from 3.81 to 3.14 gallons or 22%

» Decreased natural gas use per case from .025 therms to .014 therms or 48%

» Decreased electricity use per case from .75 kWh to .58 kWh or 29%

» Decreased green house gas emissions by 436 metric tons of C02
    (That’s equivalent to the annual emissions from 72 PASSENGER VEHICLES)

While decreasing wastewater, natural gas use and electricity use Mark West has:

» Increased bottling from 1.78m/year to 2.6m/year or 46%

» Increased tank storage from 1.19m gallons to 1.36m gal or 14%

» Increased barrels stored from 30,534 to 45,153 or 48%

» WITHOUT INCREASING REFRIGERATION TONNAGE!

Energy Efficiency Upgrades:

» Insulated 50 wine tanks

» Insulated glycol storage tank to reduce energy load

» Installed hot and cold water storage tanks to reduce energy load

» Replaced water boilers with 87% efficiency water heaters

» Replaced metal halide lighting with high efficiency T-5 fluorescents

» Replaced air compressor with variable speed on-demand features vInstalled variable frequency drives on motors

» Implemented wastewater monitoring system to regulate aerator use

» Installed Cool® roof -foam insulated, reflective roofing

» Installed hot and cold supply line insulation

» Installed glycol cooling system (replaced Freon air handler units

Water Efficiency Upgrades:

» Centralized water intakes to increase psi which reduces water use

» Installed a mechanized Tom Beard barrel washer with capture of final rinse for re-use as first rough rinse.
    Estimated water savings of 33 %

» Recapture of water softening discharge for re-use

» Added steam sterilization of bottling lines: Daily average water savings of 1,700 GALLONS

» Installed a very impressive Wiped Film Rotating Disc evaporator for wastewater treatment.
    This will allow us to reuse 2,300 GALLONS of treated process water per day.

» 24K sq. ft. Canopy Project - Will divert up to 1 million gallons of rain water out of waste water pond.
    Equivalent to ~ 250,000 cases of additional production.

In the Near Future:

» Installation of renewable energy technology: solar photovoltaic and thermal solar power

Save the Environment, Save Some Money:

» PG&E natural gas savings: 20,849 @ therm @ $0.80 = $16,679

» PG&E rebates for electricity savings: $187,292

» PG&E estimated avoided energy use: 2 million kW and 50,000 therms
