Northern Technologies International Corporation Awarded Contract From State of Minnesota for Natur-Tec(r) Compostable Plastic Bags

MINNEAPOLIS, Apr 13, 2009 (GlobeNewswire via COMTEX News Network) -- Northern Technologies International Corporation (Nasdaq:NTIC), today announced that the State of Minnesota, Department of Administration, Materials Management Division has recently selected NTIC as a vendor for providing Natur-Tec(r) Compostable Plastic Bags to various state agencies. In addition, under Minnesota's Cooperative Purchasing Venture (CPV), entities such as counties, cities, townships, school districts, charitable organizations and community clinics are also eligible to procure Natur-Tec(r) compostable plastic bags from NTIC at the prices and terms negotiated with the State.

"We are very proud that the State of Minnesota has selected our Natur-Tec(r) compostable plastic bags" said Patrick Lynch, CEO of NTIC. "This is especially timely in the light of recently introduced bills in the Minnesota House and Senate (HF403 / SF383) that would require the use of compostable plastic bags for yard waste collection in the seven-county Twin Cities metro area. We are pleased to be a part of the movement that is positioning Minnesota as a leading hub for bioplastics."

NTIC's Natur-Tec(r) branded compostable plastic bags are manufactured using NTIC's patented and proprietary technologies and are intended to replace conventional petroleum-based plastics. The exceptionally broad Natur-Tec(r) bioplastics portfolio spans flexible film, foam, rigid injection molded materials and engineered plastics. Natur-Tec(r) compostable products, such as shopping and grocery bags, lawn and leaf bags, can liners, and pet waste collection bags, are engineered to be fully biodegradable in a professionally managed composting environment. Unlike the competing plastic products claiming to be 'degradable' or 'oxo-degradable' that only break down into smaller plastic fragments, Natur-Tec(r) compostable plastic products will breakdown into water, CO2 and biomass within 180 days in accordance with the ASTM D6400 standard for compostable plastics and are certified 100 percent biodegradable and compostable by the Biodegradable Products Institute.

Natur-Tec(r) products are engineered using a proprietary blend of natural polymers and organic materials to create biobased and biodegradable plastics. These products do not contain any conventional plastics such as polyethylene, polypropylene or polystyrene. By using Natur-Tec(r) products as an alternative to conventional plastics, industry and consumers are able to reduce their carbon footprint and move towards a zero carbon or carbon neutral footprint.
