Evolution in a changing environment

Envo Global Trading Sdn Bhd

Environmentally sound practices, resource conservation and sustainable growth are increasingly important requirements of today’s society.

The world increasingly understands that the philosophies of the last century of “Bury or Burn and Forget” are no longer an acceptable option for the 21st Century. What has traditionally been called “disposable packaging” is in fact, not disposable, but merely relocat-able. It is relocated to holes in the ground or relocated into the atmosphere “up in smoke” or to our water ways. ​All ways, they continue to pollute, just in another form. Landfill sites across the world are nearing their capacities. There are fewer and fewer sites left available that can be used for landfill. Most domestic and commercial waste consists of plastics that cannot biodegrade. Plastic can take up to 400 years to start to break down and can still be there in 1000 years.

​The consequences of plastics pollution creates a multitude of environmental hazards on land, at sea and in the atmosphere.

 

Top Two Pollutants

​Styrofoam

Exposure to Styrofoam (especially heating our food on Styrofoam packaging which releases toxic fumes) will increase the risk of health issues over a period of time. A few studies have shown that chemicals in Styrofoam (mainly “Styrene”) decreases birth rates, increases the risk for leukemia and lymphoma, and effects the liver, kidney, and stomach. Exposure to Styrene can also cause eye and mucous membrane irritation, as well as gastrointestinal harm.

Styrofoam takes hundred of years to decompose naturally and recycling options for Styrofoam are very limited since the process of melting and reforming it is too labor-intensive and toxic for recycling centers to handle. Hence, people normally turn to an easy option of just throwing it away. Disposed Styrofoam in landfills breaks down into small pieces and normally end up into the ocean and the environment. Marine animals and birds mistakenly consume these small pieces of Styrofoam as food and eventually effect the whole chain of events. Marine animals that feed on these toxic pieces of Styrofoam might end up in our bodies as we eat them and cause us to take in those harmful chemicals as well.

Traditional Plastics (Petroleum-Based)

Plastics pollution has become a global concerns across Malaysia and around the world due to mass amount of plastic wastes end up in landfills and the ocean. Harmful chemicals contained in plastics are present in the bloodstream and tissues of almost each one of us. Plastic is not biodegradable and it takes more than 500 years to be completely degrade. It will only breaks down into smaller particles and its toxic chemicals will end up ingested by wildlife or marine animals, which we have also consumed. When it undergo further degradation, where it is not visible to our naked eyes, we are actually breathing in these tiny toxic particles into our bodies without realization.

These are two classified plastic-related chemicals which are critical concern for human health, Bisphenol-A (BPA) and phthalates, an additive used in the synthesis of plastic. BPA has been recognized as an endocrine disrupting chemical that is said to affect normal hormonal function. Besides the health risk about BPA, phthalates which are usually added to plastics, will leach out gradually for sometime. It is potentially dangerous especially when it is use as a container or packaging for food because phthalates in plastic have the possibility to leach out into the food and may go directly into the bloodstream which cannot be detoxify. This means unhealthy exposure levels, and can indirectly impact in susceptible populations such as newborns.

Worthwhile, Timely, Topical

A SMART AND SUSTAINABLE PLASTIC ALTERNATIVE

What are bio-polymers?

Our research in the area of biodegradable polymers, (readily available renewable resource) as a base for production of biodegradable polymers, has resulted in products that can meet or exceed the specification of their plastic counterparts. It can be derived from plant starch (e.g. corn, sugarcane, tapioca, or cellulose) or a new range of biodegradable synthetic material.

Degradable

That undergoes significant changes in its chemical structure when subjected to various specific environmental conditions, resulting in a loss of properties that can be measured by standard methods, in a given period of time.

Biodegradable

Our material are biodegradable and compostable. It is capable of undergoing biological anaerobic or aerobic degradation leading to the production of carbon dioxide (carbon neutral), water, methane, biomass, and mineral salts, depending on the environment conditions of the process. It undergoes degradation resulting from the action of naturally occurring microorganisms such as bacteria, fungi and algae which are present in the environment.

Compostable

That undergoes degradation by biological processes during composting to yield carbon dioxide (carbon neutral), water, inorganic compounds and biomass at a rate consistent with other compostable materials and leaves no visible, distinguishable or toxic residue.

Top Left Quadrant
Bio-based or partly bio-based non-biodegradable plastic such as green PE, PP or PET (drop-ins) and bio-based technical performance polymers such as PTT or TPC-ET.

Top Right Quadrant
Plastics that are both bio-based and biodegradable, such as PLA, PHA, PBS or starch blends.

Bottom Left Quadrant
Conventional fossil fuel based plastic bag.

Bottom Right Quadrant
Plastic that are based on fossil resources but biodegradable such as PBAT, PCL and some PLA.

Therefore:

  • Not all bio-based are biodegradable, likewise not all biodegradable are bio-based.

  • All compostable are biodegradable, but not all biodegradable are compostable.

  • Top Right Quadrant is also known as Bio-based Biodegradable, which where Our Products fall into.

Testing Method

To test for Bio-based Carbon Content

ASTM D6866-16 : Standard Test Methods for Determining the Bio-based Content of Solid, Liquid and Gaseous Samples Using Radiocarbon Analysis to test for the present of Carbon-14. Most commonly used is Method  B – Accelerated Mass Spectroscopy (AMS)

To test for Starch Content

QB/T 2957-2008 – Determination of starch content of starch based plastics Thermogravimetry (TG) or
ISO 11358 : 1997 – Thermogravimetry (TG) of Polymers

A test specimen is heated at a constant rate with a controlled temperature programme, and the change in mass is measured as a function of temperature. Alternatively, the specimen is kept at a given constant temperature and the change in mass is measured as a function of time over a given period. In general, the reactions which cause the mass of a test specimen to change are decomposition or oxidation reactions or the volatilization of a component. The change in mass is recorded as a TG curve.

​To test for Compostable

ASTM D 6400 or EN 13432

Description of requirements to pass ASTM D 6400:
To be considered “compostable” by either ASTM D 6400 or EN 13432, the product must demonstrate the three following conditions:

  • Disintegration – After starting with the product cut into 2cm lengths, in 60 days of composting under laboratory controlled composting conditions, 90% of the specimen must pass a 2mm sieve.
  • Biodegradation – 90% of the organic carbon  must be converted to carbon dioxide in 180 days, when compared to the positive control (cellulose).
  • No Adverse Effects on the Quality of the Compost – Plant Growth – The germination rate and the plant biomass of the sample composts shall be no less than 90% that of the corresponding blank compost for two different plant species following OECD Guideline with the modifications found in ​Annex E of EN 13432.
