Frequently Asked Questions

What are our products made of?

Our product is a cost effective, degradable plastic. It is made of EPI (Environmental Products Inc.) 100% oxo-biodegradable material (ASTM 6954-04, EPI cert. no. 3010508303). This material is plastic, with TDPA (Totally Degradable Plastics Additives) added.

How is it different to products made from conventional plastics?

TDPA when added in small quantities to the most common and widely used commodity resins during the manufacture of finished plastic products, causes the modified plastic to degrade at a controlled rate.

EPI’s TDPA formulations catalyse or accelerate the degradation rate of plastics, increasing the rate of degradation by 100s – 1000s of times faster.

The overall process from polymer to water, carbon dioxide and bio-mass is called oxo-biodegradation. Test results and proven scientific studies have verified that TDPA incorporated products degrade, disintegrate and biodegrade.

How does it degrade?

When discarded in soil in the presence of micro organisms, moisture and oxygen, it will biodegrade, decomposing into simple materials found in nature. The product is degradable to non-toxic end products within 1-2 years, when discarded in landfill. Once in landfill, the micro organisms break it down to Carbon Dioxide CO2, water, humus (complex organic substance which is important to the fertility of soils), and trace elements (micro-nutrients which are required by living organisms). They are consumed by micro organisms after the additives have reduced the weight. Other relevant factors include:

  • Does not leave fragments of petro-polymers in the soil
  • Does not emit methane or nitrous oxide
  • Can be safely recycled
  • Can be composted – Degradable bags are ideal for disposal in landfill. The bags are also designed to degrade in home compost or commercial compost. However, the speed of degradation always depends on the actual location and condition of the compost

Is it more expensive than the products made from conventional plastics?

Our products are sold at a very competitive price compared to like products in regular plastic sold through other supply companies. You will find that generally our prices are less than or equal to lowest prices advertised.

Is it visually different or less durable?

Biodegradable plastics incorporating TDPA perform as well as and are visually indistinguishable from conventional non-degradable plastic products. They are also compatible with existing recycling operations and can be safely commingled with conventional plastic inputs prior to the onset of degradation.

Is the product toxic?

Degradable products made from EPI technology are non-toxic. TDPA products are food contact compliant and meet applicable US, European and Canadian Standards. The compliance is supported by scientific testing and published test reports that enable EPI to provide legitimate environmental claim statements. Published works has also demonstrated that compost made from plastics incorporating TDPA has no toxic effect on sensitive plant or animal life.

How long do they take to break down?

The products break down within 1-2 years as opposed to 100s-1000s years. We have expanded our product range to include other plastic single use items from the same material. These harder plastic items take 3-5 years to break down.

What is the average cost per patient?

The average cost to barrier equipment for one patient’s restorative treatment visit is approximately 55 cents. That includes barriers for triplex, high speed and slow speed handpieces, suction, suction rest, bracket table, instrument tray, light handles, and two grab bags for retrieval processes.
