Biodegradable FAQ’s

1. How will the government’s ban on styrofoam affect the availability of Sanicup?

The government’s ban on styrofoam as of 2020 is only applicable to imported styrofoam for use in the food service industry. The local styrofoam manufacturers, which includes Santainers Limited, have been required to make their products biodegradable.

2. What plastic raw material is used to manufacture Biodegradable Sanicup ‘styrofoam’?

The raw material is made by Styrochem Canada Limited. The grade is EVRgreen EPS #evT280czEX. Our Biodegradable Foam has been approved by the United States Food & Drug Administration (USFDA), Health Canada and the European Union. See more at www.styrochem.com/products/evergreen-eps

3. What is the biodegradation test results?

Products made from EVRgreen EPS have been shown to degrade 92% over 4 years in biologically active landfills such as the Beetham Dump. The test used is the International ASTM D5511-11 test method astm.org/Standards/D5511. Test results of Sanicup products show degradation of 38.7% over a period of 223 days. The test was done by Eden Research Laboratory, Albuquerque, New Mexico, USA www.edenresearchlab.com

4. How does biodegradation work?

Natural microorganisms found in biologically active landfills, such as the Beetham Landfill in Trinidad, will degrade the polystyrene foam. This process of degradation is similar to that of other organic material such as food waste and paper.

5. What is left after biodegradation?

Sanicup biodegradable ‘styrofoam’ products are 90% air and 10% plastic so after they are discarded and enter the landfill they break down into a small percentage of top-soil like mass, methane and carbon dioxide which is typical of most degradable organic materials.

6. How can I identify the biodegradable Sanicup products?

The approved Sanicup products now have a sticker on the packaging that says ‘biodegradable’.

7. How will this switch to biodegradable affect the price of Sanicup?

Biodegradable Sanicup will still be the best low priced option for the food service industry when compared to the alternatives on the market which are significantly more expensive.

EvrGreen™ Biodegradation Test

StyroChem Canada, Ltd. has pioneered the first biodegradable expandable polystyrene (“EPS”) resin in the market, EVRgreenTM. In December 2015, Eden Research Laboratories, located in Albuquerque, New Mexico, U.S.A. (“Eden”), completed a four year biodegradation study of test samples of EPS made with StyroChem’s proprietary EVRgreenTM resin.

The study utilized ASTM International’s Standard Test Method for Determining Anaerobic Biodegradation of Plastic Materials Under High-Solids Anaerobic-Digestion Conditions, known as ASTM D5511. ASTM D5511 determines the rate and degree of anaerobic biodegradation by measuring the volume of carbon dioxide and methane, or change in mass, as a function of time (days) of exposure to anaerobic-digester sludge. This method is designed to resemble many conditions in wetter or biologically active landfills.

The study recorded the rate and degree of biodegradation of the EVRgreen sample EPS compared to a test sample of standard EPS, as well as a positive control and a negative control, under similar test conditions. The test results showed biodegradation of 91.9% of the EVRgreenTM sample over four years, while the standard EPS degraded only 5.75% over the same four year period.

Note that the test was conducted under conditions that simulate both wetter and biologically active landfills. Wetter or biologically active landfills may not exist in your area. The stated rate and extent of degradation do not mean that the test sample will continue to decompose.

StyroChem has conducted additional biodegradability tests of EVRgreenTM with both Eden and other accredited laboratories, and the results of such additional tests support the biodegradability of EVRgreenTM as determined by Eden in the ASTM D5511 test under conditions that simulate both wetter and biologically active landfills.
