SAN DIEGO--(BUSINESS WIRE)--July 9, 2007--Green Star Products, Inc. (OTC:GSPI) announced today that its Phase II Algae-To-Biodiesel Demonstration Facility (40,000 liters) has been successfully completed.

GSPI's May 11, 2007 press release, titled 'Green Star Completes Algae Phase I Demo Facility', explained in detail the five most important operating parameters that need to be controlled. However, management of these parameters has so far eluded the commercial microalgae industry.

These parameters include daily and seasonal pond temperatures, pH, evaporation, salinity and invasion by outside organisms.

Mr. Joseph LaStella, President of GSPI, stated, "The GSPI demonstration facility which is a full-size module of our planned production facility furnished GSPI with a wealth of field information and patentable low-cost construction techniques."

Phase II testing included pushing the survival environmental envelope of the developed algae strain (zx-13) utilized by GSPI.

Mr. LaStella further stated, "The zx-13 strain survived at elevated temperatures, much higher than any tested in most of the available literature over the last 50 years. Temperature testing by Universities usually cuts off at 90 degrees F, this zx-13 strain successfully endured peak temperatures of 115 degrees F for several hours on successive days."

Also tested were salinity levels outside the normal operating range for saltwater algae and the zx-13 strain exhibited strong survivability. The zx-13 strain also exhibited acceptable 21% oil content. The balance of the biomass is being tested for high-grade protein content to be used as animal feed and organic fertilizer.

The only item that caught GSPI personnel unprepared was the exponential growth of the algae.

Mr. LaStella stated that "Growth rates of algae are phenomenal, just consider that many algae, including the zx-13 strain, are capable of reproducing themselves from 1.5 to 4 times per day depending on environmental conditions. This means that, even at nominal growth rates, one cell will grow to one million microalgae cells in 15 days that continue to grow to one trillion cells in the next 15 days if conditions and space for growth are available."

Algae harvesting occurred sooner than expected and GSPI had not yet received all harvesting equipment.

GSPI harvesting techniques allow only the algae cells larger than 2 microns to be captured and the smaller size algae returned to the pond to reproduce.

In an effort to harvest as soon as possible a 1,750 rpm vane pump was used instead of a slurry pump and resulted in shearing and damaging the smaller algae cells returning to the pond, which caused a temporary pond shutdown.

Mr. LaStella stated that: "This is not an operational problem, it's only part of the learning curve."

The success of the Montana demonstration facility has paved the way for the next stage, which is a 100-acre production facility. At the present time GSPI is in negotiations in three states for this 100-acre facility, i.e. California, Missouri and Utah.

One of the major considerations for our next site is the ability to expand to a much larger facility of 500 to 1,000 acres.

Mr. LaStella also re-stated five important algae factors, which will play a major role in weaning the U.S. off foreign oil and reduce global warming. These are:

1) Algae produce 100 times more oil per acre than traditional food oilseed crops (i.e. corn, soy, etc.)

2) Algae eat CO2, the major Global Warming Gas, and produce oxygen

3) Algae require only sunshine and non-drinkable (salt or brackish) water

4) Algae do not compete with food crops for either agricultural land or fresh water

5) Algae can reproduce themselves and their oil every 6 hours, while it takes Mother Nature millions of years to produce crude oil in the ground
