is not clear the question

In plants, the main polymers are cellulose and lignin. Cellulose is biodegradable, and lignin much less. Would you like to use them as such, extract from plants a monomer which could be polymerized into a new biodegradable polymer, or modify the aforementioned polymers to produce ne ones (like cellulose acetate, for example) ? Your question should indeed be clarified.

 select the chemistry of the plant based on the polymer which is supposed to be degraded. If both are similar it is possible that it will degrade. Look at the nature more

1. Functional properties

2. Yield

3. Cost of extraction and processing

4. Investment needed to scale up and ensure availability
