Oxium is US-patented, oxo-biodegradable additive that speeds up the molecular and chemical degradation of plastic, thus helping to solve the massive accumulation of plastic waste.  Oxium's proprietary formula is made of naturally available minerals that are non-toxic, non-heavy metals.  Oxium is used as an additive in low dosage towards regular plastic production (does not require separate/special machineries) and has proven to be an effective and every economical solution towards green plastic.     

TECHNOLOGY HIGHLIGHTS

 
  • Oxo-biodegradable additives degrades plastic until it decomposes back into the soil, eaten by microbes (not more physical fragmentation resulting into micro-plastics, but instead molecular and chemical degradation).

  • Very competitive price, economically viable across plastic products and market segments.

  • Proven degradation through oxo-biodegradation process as tested and passed ASTM 6954.

  • Has been widely applied to shopping bags, garbage bags, packaging products, food and non-food packaging, disposable food trays, cups, utensils (spoons, forks, straws), polybags, and many others.

  • Has Ecolabel Indonesian Standard (SNI Ekolabel) and Type 2 Ecolabel.

  • US Patents and International Rights Reserved.

 
 

ASTM 6954 TEST RESULT

 
 

As shown in figure 1, the numbers of colonies from flasks with no film and with polyethylene were very low and tended to decrease after 90 days of cultivation. On the other hand, the flasks with UV exposed Oxium fragments showed high number of colonies and the number increased with the cultivation time.

The test results verified that the UV exposed Oxium film were used as nutrients bu the fungi and the material will be biodegraded to CO2, H2O and biomass.

 

 
 

ASTM D5208, ASTM G21-09 and ASTM 6954 are the Test Standard on Degradable Plastics & Proof that Oxium film become food sources for micro-organism.

 

 
 

The evaluation was carried out on plastic film sample made from Polyethylene with OXIUM additive by following ASTM D 6954-04 “Standard Guide for Exposing and Testing Plastics that Degrade in the Environment by a Combination of Oxidation and Biodegradation” and consists of 3 (three) Tiers as follows:

Testing in Tier 1 showed that decrease in properties of plastic sample due to oxidation via thermal and UV irradiation was confirmed. The elongation of plastic sample was decreased from 571% to become 2% after 168 hours UV irradiation at 50oC with control irradiance at 0.78 ± 0.02 W/(m2.nm) at 340 nm as per ASTM D 5208. Furthermore, it was confirmed that the molecular weight of the plastic sample decreased from 1.06 x 105 g/mol to become less than 2.5 x 104 g/mol after 14 days of UV irradiation. UV irradiation caused fragmentation of the sample to become powder. Volatile Mass Analysis of the sample after UV irradiation showed very low content of volatile substance, i.e. 0.20 – 0.25%.

Testing in Tier 2 was focused on biodegradation in composting condition towards samples, such as blank (compost only without polymer addition), UV irradiated sample (polyethylene with OXIUM additive), positive control (cellulose), and negative control (polyethylene). It was confirmed that even at 45 days of composting, the microbial degradation and assimilation of UV irradiated sample and positive control was still in progress, and had not yet been in stationary phase. Under assumption, that the complete degradation resulted in 70% of CO2 conversion and 30% of biomass formation, the percentages of degradation at 45 days composting were 60.1% and 75.9%, respectively for UV irradiated sample and positive control.

Testing in Tier 3 was focused on post-degradation impact to the environment after completion of Tier 2. The followings were confirmed in the tests.

  1. Terrestrial toxicity test resulted no difference in pH among compost extracts from blank, UV irradiated sample, positive and negative controls, around pH 7.6-7.7, suggesting no adverse effect of biodegradation residues of UV irradiated sample to the environment.

  2. Aquatic toxicity test following Brine Shrimp Lethality Test (BSLT) showed no significant toxicity on the compost extract from UV irradiated sample. The value of LC50 was greater than 1,000 ppm, indicating insignificant level of toxicity.

  3. The effect of compost extract from UV irradiated sample on seed germination was not observed. The ratio of germination is mostly similar to blank and positive control, i.e. more than 90% of seed were germinated.

  4. Plant growth of tomato was not inhibited by compost from UV irradiated sample and was mostly similar with growth using compost from blank and positive control.

  5. There was no effect of compost extract from UV irradiated sample on growth of earthworm and no significant difference in growth of earthworm when compared with blank and positive control.
