Greystone Logistics Announces Series of Purchase Orders for Recycled Plastic
Pallets

TULSA, OK--Apr 30, 2007 -- Greystone Logistics, Inc. (OTCBB: GLGIE) recently
received a renewal of a long-standing purchase order from Miller Brewing for
production and delivery of their 100% recycled plastic pallets. As in past
years, this purchase order represents Miller's estimate of the pallets it
expects to order from Greystone over the course of the next twelve months. The
company also received purchase orders for approximately 7,500 pallets from over
45 companies within the last 30 days, including Merck & Co., Akzo Nobel, West
Pharmaceutical Services, and Apotex Group which were secured by its outside
sales group, Decade Products.

"We welcome the continuation of our multi-year relationship with Miller
Brewing," said Warren Kruger, CEO of Greystone. Mr. Kruger continued, "The
growth in our product line and production capacity during the last year is
allowing Decade Products to expand our reach to new users of our 100% recycled
plastic pallets. Greystone's dedication to helping the environment with our
'green' recyclable products is gaining momentum. The Iowa Recycling Association
recently awarded Greystone the Recycled Product of the Year Award for last year.
The environmental benefits of our recycled pallets include the reduction of
biological infestations, prevention of deforestation for wood pallets, and the
diversion of post-industrial plastic from land fills. I anticipate that with the
purchase orders currently in place and if plastic prices hold firm, the balance
of calendar year 2007 will be profitable for the company."
