Compostable vs Bio-degradable - What is the difference?

the difference between compostable & biod-degradable

Bio-degradable bags simply means that they can be broken down into numerous small pieces in time which, according to new studies, can be even more harmful to the environment than they weren't.

A compostable plastic is defined by the standards association ASTM International (ASTM) as “a plastic that undergoes degradation by biological processes during composting to yield carbon dioxide (CO2), water, inorganic compounds, and biomass at a rate consistent with other known compostable materials and that leaves no visible, distinguishable, or toxic residue.”

With increasing public concern over plastic wastes accumulation, the demand for quickly degradable plastics plastics mounting. While traditional bio-degradable additives only break down plastic into small debris, new additives are invented to make palstic compostable. Also, new technologies are available to make plastic from corn starch. Now, based on these 2 new ways, we can make compostable plastics, namely:

Oxo-biodegradable plastics

Plastics made from polymers such as PE (polyethylene), PP (polypropylene), and PS (polystyrene) containing extra ingredients (not heavy metals) and tested according to ASTM D6954 or BS8472 or AFNOR Accord T51-808 to degrade and biodegrade in the open environment.

As stated by Waste Management World, in oxo-biodegradable plastics, the degradation process does not just cause fragmentation but changes the molecular structure of the material so that it decays in the same way as a normal leaf or blade of grass does. The plastics will disappears completely without leaving plastic, harmful residues or long-term damagesl.  OXO-biodegradable plastic degrades in the presence of oxygen, and the process is accelerated by UV and heat. It can be recycled  during its useful life with normal plastic.[1] It is not designed to be compostable in industrial composting facilities according to ASTM D6400 or EN13432, but it can be composted in an in-vessel process.

Vegetable based plastics

(Also loosely known as bio-plastics "bioplastics" or "compostable plastics"). These are tested in accordance with ASTM D6400 or EN13432 to biodegrade in the conditions found in industrial composting or biogas facilities.  Some bio-plastics can degrade in 1,000 years. Here, we are talking about those which decay quickly.

How can we help in making the earth greener?


For sustainability, we believe that every corporation has the social responsibility to protect the environment while making profit. At Repro-plastics, we make the above 2 types of compostable bags by using world famous materials and additives which can control the life span of the bags in a wanted time frame.
