1 Product Features In properly controlled landfills BIOflex PVC will vanish in 3 to 5 years 80% of the content is derived from sources other than petroleum Formula is non-toxic Contains no heavy metals, pesticides, bleaching agents, DOP or similar plasticizers, glycol either or carcinogenic coloring agents Tear and fade resistant Compatible with UV, solvent and screen printers Formula Details PVC has a remarkable balance of properties; it is strong, resistant to oil, chemicals, sunlight and weather. PVC is also flame resistant, easily decorated and low in cost. At one time, PVC was often formulated with little regard for avoidance of toxic ingredients. This is no longer true. BIOflex TM PVC contains no toxic materials. It is composed of pure PVC resin, fine particle limestone to provide opacity, plasticizer of vegetable origin to provide flexibility and the titanium pigment used in high quality paints to add sunlight resistance. More than 80% of the content of BIOflex is derived from sources other than petroleum. Before BIOflex, PVC had been immortal in the landfill; no degradation was found after decades of landfill burial. When degradable materials, such as starch, were added, they were consumed in the landfill but the PVC itself was untouched. Ultraflex Systems has developed a nontoxic formula that, at very low levels, enables landfill decomposition of BIOflex PVC. BIOflex has been engineered to be the first truly environmentally friendly, biodegradable PVC. Worldwide patents covering the BIOflex composition are pending. In the landfill, the carbon and hydrogen content of BIOflex are partly consumed by the biomass organisms and partly released as methane from fermentation. In a well managed landfill, methane is harvested for use as fuel. The chlorine content of BIOflex is partly consumed and partly converted to soluble chloride, this has value as fertilizer since it makes soil nitrogen more rapidly available to plants. In experiments using landfill into which BIOflex had decomposed as compost in potting soil, plants and vegetables sprouted more rapidly than in controls.

2 Certified Testing In an ISO study by an independent testing laboratory, addition of BIOflex TM to a landfill not only did not inhibit, but actually increased the level of biological activity. This ISO test is designed to ensure that materials added to a landfill do not release toxic substances. BIOflex begins to degrade in the landfill within a few weeks and depending on thickness and quantity added, the PVC will vanish in 3 to 5 years. It should be noted that landfills can be managed by control of temperature and moisture content so as to increase the level of biological activity. The Woods End ASTM D5526 data show that the ratio of the fraction of organic carbon and hydrogen from BIOflex released to the air, and the fraction delivered to the solid biomass varies with landfill conditions, such as temperature and water content. The fraction released to the air is mostly methane, which can be harvested for fuel, along with the methane released by other compoents of the landfill, such as paper. Variability in the ratio of end product to the air and to the biomass is also typical of ther land-filled materials, such as paper. BIOflex has been tested for field performance including strength and weathering in the above tests as well as exposure to 2000 hours of laboratory UV, which BIOflex showed no signs of discoloration. Packaging BIOflex sample rolls are packaged using a stretch film that is made primarily of linear low density Polyethylene (LLDPE). All materials used in the production of this packaging are completely recyclable as low density polyethylene. Additionally, the protective shipping tubes are made from recycled materials and are fully recyclable.

4 Determination of Anaerobic Biodegradation ASTM D-5526 Results For the following article: BIOflex FL an advertising media for indoor or outdoor applications. Executive Summary BIOflex FL film #7450 provided was tested for biodegradation according to ASTM procedure D Standard Test Method for Determining Anaerobic Biodegradation of Plastic Materials Under Accelerated Landfill Conditions. The test was conducted at 35 C for 104 days, at three moisture levels in an inoculum substrate prepared from municipal solid waste. Apparent net decomposition of the test material was calculated from the cumulative biogas-carbon evolved from the test vessels after subtracting the biogas-carbon evolved from the blank inoculum substrate at the same dry-matter level. Apparent net decomposition of the BIOflex FL material at the end of the test period at the 45% dry-matter (DM) test conditions was 14.5%. BIOflex FL decomposition at 35% DM rose to 18% at day-35, then declined steadily to negative values, indicating inhibition of the inoculum substrate decomposition at that point. Biogas evolution from the BIOflex FL vessels at 60% DM was slower than the corresponding blanks for the first 60 days, with cumulative net decomposition of negative 9% indicating slight inhibition of the inoculum substrate. The cellulose powder reference material showed 16% net decomposition in the 60% DM conditions, and net negative decomposition (apparent inhibition) at 35% and 45% DM. Biogas evolution from the blanks indicated that total decomposition of the organic carbon in the inoculum substrate was 21%, 28%, and 18% in the 35%, 45%, and 60% dry-matter conditions, respectively. Conclusion Addition of BIOflex FL to a landfill does not interfere with its digestion of other materials. Woods End data per ISO indicate that it improves this ability. BIOflex FL contains no detectable heavy metals and no zinc (which is ecotoxic). The plasticizer used is derived from a natural product and is completely consumed by the landfill. In an anaerobic landfill, BIOflex FL loses molecular weight to the point where microbes can consume it. No detectable monomer is formed. The Woods End ASTM D5526 data show that the ratio of the fraction of organic carbon and hydrogen from BIOflex FL release to the air, and the fraction delivered to the solid biomass varies with landfill conditions, such as temperature and water content. The fraction released to the air is mostly methane, which can be harvested for fuel, along with the methane released by other components of the landfill, such as paper. Variability in the ratio of end product to the air and to the biomass is also typical of other land-filled materials, such as paper. Most of the chlorine content of BIOflex FL is converted by the landfill to soluble chloride, which improves its value as fertilizer. A small fraction is taken up by the biomass as one of the essential trace elements. The minor amount of refined calcium carbonate in BIOflex FL also adds to fertilizer value in the landfill.

How does the PVC biodegrade in the landfill? A. Within landfills there are microbes, heat, pressure and little moisture. These microbes utilize the BIOflex PVC as their food source. This has been tested according to ASTM D5526. Q. What happens to the carbon and hydrogen content of BIOflex? A. The content is partly consumed by the biomass organisms living in the landfill and is partly released as methane from fermentation.

6 Q. What happens to the methane released from BIOflex? A. In a well-managed landfill the methane is harvested for use as fuel. Q. What happens to the chlorine content of BIOflex? A. The content is partly consumed and partly converted to soluble chloride. Q. Why is converted soluble chloride positive? A. Soluble chloride has value as fertilizer since it makes soil nitrogen more rapidly available to plants. In experiments using landfill into which BIOflex had decomposed, as compost in potting soil, vegetables sprouted more rapidly than in controlled vegetable specimens. Q. How long does it take for the PVC to biodegrade? A. BIOflex PVC will begin to breakdown within 90 days in landfill conditions and depending on thickness and quantity the PVC will vanish in 3 to 5 years. Q. Does printing on BIOflex change the biodegrading process? A. No. BIOflex PVC will still degrade. Q. Will BIOflex begin to degrade in application? A. No. BIOflex requires the absence of water and air in order to begin biodegrading. This process begins after the product is disposed into a controlled landfill. Testing & Patents Q. What testing has been done on BIOflex? A. BIOflex has been tested by an accredited laboratory using the ASTM D5526 and ISO Q. What conclusions can be made from the ASTM D5526? A. The data shows that when BIOflex is added to a landfill it does not interfere with its digestion of other materials but rather improves this ability. The ratio of the fraction of organic carbon and hydrogen released into the air and the fraction delivered to the solid biomass varies with landfill conditions such as temperature and water content. The fraction released to the air is mostly methane, which can be harvested for fuel, along with the methane released by other components of the landfill, such as paper. Q.
