Narasimhan Santhanam No. Some bioplastics (usually those made from starch) degrade quickly in many environments; some (such as those from cellulose) degrade quickly in select environments, and some (those made from vegetable oil etc for instance), are actually drop-in replacements and do not degrade at all. So, well, many bioplastics are not biodegradable. Finally, a few conventional plastics actually biodegrade fast! Like

Narasimhan Santhanam And here are some links for you on both biodegradable bioplastics and bioplastics that are NOT biodegradable

1. Biodegradable bioplastics - Link ; 2. Non Biodegradable bioplastics - Link

Narasimhan Santhanam And finally, here are some petro-based plastics that ARE biodegradable! - Link Like

Vijay Wilfred Wow, petro-based plastics that can biodegrade? That sounds fascinating. But why are they not so prevalent in today's market yet? Like

Narasimhan Santhanam Yep, there are petro plastics that can biodegrade.

Why do you think they are not used much? It is a no brainer - they cost a heck of a lot more than the PEs and PPs! While PE/PP and other conventional non-degradable petro plastics cost about $1-$1.5/Kg (depending on which country you are), biodegradable petro plastics such as PBAT can cost as high as $5/Kg. Any takers now? :-0)

Gayathri Kumar The feedstocks used for bioplastics manufacturing can be classified as follows:
First generation - Corn, Wheat, etc.
Second generation - wood, short-rotation crops such as Poplar, Willow or Miscanthus,
Third generation - biomass from algae (developmental stage) Link ;Here is a list of end products obtained from the above feedstocks - Biodegradable products - shopping/compost bags, foodware, medical applications (implants); non-biodegradable products - automotive interiors Link
