Delphi Operations Find Innovative Ways to Recycle Materials

    TROY, Mich., April 20 -- Delphi Automotive Systems
features many innovative recycling and clean programs at its 168
manufacturing operations worldwide.
    Highlights include the following:

    Plastic scrap now used for packaging.  Delphi engineers in Saginaw, Mich.,
lend their recycling expertise to area customers, plants, hospitals and
suppliers by receiving and recycling almost 1,200 tons of packaging plastics a
year.  This material waste, formerly targeted for landfills, is collected and
separated by type using minority suppliers or centers for the physically
challenged.  This plastic material is ground and reused in molding new
packaging.
    "Everyone wins through this program," said Sam Izzat, Delphi senior
environmental engineer and program coordinator.  "Through cooperative
recycling efforts, the hospitals eliminate their plastic waste materials at
virtually no cost, the community gets new jobs, and Delphi gets low-cost
packaging material."

    Chrome recovery cuts hazardous waste.  Delphi's Kettering, Ohio, plant has
found a way to retain the sealing, wear and corrosion-resistance benefits of
chrome-plating the rods of its shock absorbers and struts while greatly
reducing the associated hazardous waste.
    Traditionally, a high percentage of chrome used in the plating process
requires treatment and disposal.  Recently, engineers at Kettering installed a
system that recovers and reuses much of the chrome that was going down the
drain.
    The system features an ion exchange unit containing an electrically
charged cation resin that is specifically formulated for use with chromic
acid.  The impurities in the water attach themselves to the resin, while the
chrome passes through the unit to be reused.  The impurities are flushed out
as waste.
    The process captures more than 70 percent of the chrome that once went to
a waste treatment plant.  The Kettering plant has cut its yearly chromic acid
purchases from 350,000 pounds to 150,000 pounds.

    Recycling in Support of OEM Customers.  Since mid-1997, Delphi's Lockport,
N.Y., facility, has recycled 500 tons of plastic materials ordinarily disposed
in landfills.  In addition to saving at least $50,000 in disposal fees
annually, the site expects to generate a similar amount in revenue, selling
the scrap plastic to a local firm.
    More significantly, much of the recycled plastic is manufactured into
packaging materials that support various vehicle manufacturing programs in
Europe.

    Selling of recycled materials.  Two Delphi plants in Flint, Mich. (Flint
East & West) recycle more than 80 different by-products and scrap materials,
including ceramics, plastics, paper, cardboard, steel, precious metals,
solvents and oils.  Delphi resells the recycled material for about $3.3
million yearly.

    CLEAN PROGRAMS
    Highlights of Delphi's efforts to keep its facilities environmentally safe
include:

    Hazardous waste reduction in Mississippi.  Over the past 10 years,
Delphi's Brookhaven, Miss., plant has reduced its hazardous waste generation
from 13,000 pounds to 1,900 pounds.  During this period, the plant has
replaced many of its hazardous waste solvents with non-hazardous solvents,
latex paints, and water-based, non-hazardous cleaners.

    Delphi's Mexico Operations Earn Prestigious Clean Enterprise Awards
    Last year, Mexico's federal environmental agency officially recognized 19
Delphi operations in the state of Chihuahua for environmental leadership and
presented the facilities with the "Empresa Limpia" (Clean Enterprise) Award.
    The award represents recognition from the highest environmental authority
in Mexico, certifying these plants are in compliance with all Mexican laws and
regulations related to the environment.  In total, 41 Delphi operations in
Mexico have achieved this recognition.

    DELPHI'S STEERING OPERATIONS -- RECYCLING BY THE NUMBERS
    Delphi's steering operations have recycled almost 19,000 tons of waste
materials that have avoided area landfills.  Specific materials recycled
include:
    *  More than 700 tons of corrugated cardboard
    *  300 tons of mixed office papers
    *  200 tons of wood
    *  200 tons of plastic and metal drums (100 percent reuse)
    *  96 tons of lead-acid batteries
    *  1,592 tons of phosphating process waste which is now used at municipal
       waste treatment facilities
    *  8,700 tons of fly ash which is now used as a natural resource
       substitute in cement manufacturing
    *  90 tons of shot blast metals
    *  And 5,800 tons of lead, steel and aluminum chips, now used as metal
       sources for foundry manufacturing of automotive parts

    Delphi Automotive Systems, with headquarters in Troy, Mich., USA, is a
world leader in automotive component and systems technology.  Delphi's three
business sectors -- Dynamics & Propulsion; Safety, Thermal & Electrical
Architecture; and Electronics & Mobile Communications -- provide comprehensive
product solutions to complex customer needs.  Delphi has more than 193,000
employees and operates 168 wholly owned manufacturing sites, 40 joint ventures
and 27 technical centers in 36 countries.  Regional headquarters are located
in Paris, Tokyo and Sao Paulo.  Delphi can be found on the Internet at
