GREYSTONE LOGISTICS REPORTS UNAUDITED RESULTS FOR QUARTER AND FISCAL YEAR ENDING
MAY 31, 2007

TULSA, OK--(MARKET WIRE)--July 18, 2007 -- Greystone Logistics, Inc. (OTC
BB:GLGI.OB - News), announced today unaudited results for the quarter and fiscal
year ending May 31, 2007. Operating profit for the 4th quarter was $280,068 with
a net income before preferred dividends of $96,791. Net income available to
common shareholders after preferred dividends was $(69,128) or $.00 per share.

Sales were $12,454,293 for the fiscal year ending May 31, 2007 compared to
$15,956,386 for fiscal year 2006 for a decrease of $3,502,093. The decrease is
primarily attributable to seasonality of certain product lines, barrel and screw
work on an injection equipment line, and delayed production startup due to the
pushback of the delivery of the new 48x40 molds and the retooling of the 48x44
mold. The new 48x40 molds were put into service in the last month of the
quarter. The net loss to common shareholders for the year ended May 31, 2007 was
($3,048,396), or ($0.12) per share.

Greystone's EBITDA (earnings (loss) before interest (including preferred
dividends), income taxes, depreciation and amortization) for the year ended May
31, 2007 is ($440,048) versus ($552,885) for the same period last year. The
fourth quarter ended May 31, 2007 resulted in a positive EBITDA of $548,059
versus $83,719 for the same period last year.

"Last year, we announced the addition of the heavy duty 48x40 rackable pallet to
our growing product line. Previously announced customer purchase orders for this
product are now being filled taking all the capacity from the 48x40 molds on our
equipment," said Warren Kruger, CEO of Greystone. Kruger continued, "We are
maintaining production 24 hours per day 7 days per week to meet customer demand
as more companies look for creative solutions to industrial packaging and
material handling enhancements that allow them to discontinue use of wooden
pallets. The environmental award winning pallets with high coefficient of
friction and racking capabilities meet or exceed ASTM standards and are being
recognized for being their ease of use, cleanliness, and long lives in highly
automated warehouses. The added bonus is our product line consists of 100%
recycled plastic which can be reground for reuse at the end of their useful
life. We look forward to continued positive results based on current and pending
orders."

(A) EBITDA represents income (loss) before income taxes plus interest,
    depreciation and amortization. The Company has included preferred dividends
    with interest expense. The EBITDA presented above while considered the most
    common definition used by investors and financial analysts, may not be
    comparable to similarly titled measures reported by other companies. The
    Company believes that EBITDA, while providing useful information, should not
    be considered in isolation or as an alternative to other financial measures
    determined under GAAP.
