Basics

One of the most commonly produced/utilized Polyhydroxyalkanoates
"PHB is produced by microorganisms (such as Cupriavidus necator, Methylobacterium rhodesianum or Bacillus megaterium) apparently in response to conditions of physiological stress;[2] mainly conditions in which nutrients are limited."
It is easily biodegradable, and unlike PLA it doesn't require the more controlled Anerobic Digestion / COmposting (Double check this)
From wikipedia
- "Water-insoluble and relatively resistant to hydrolytic degradation. This differentiates PHB from most other currently available biodegradable plastics, which are either water-soluble or moisture-sensitive.
- Good oxygen permeability.
- Good ultra-violet resistance but poor resistance to acids and bases.
- Soluble in chloroform and other chlorinated hydrocarbons.[10]
- Biocompatible and hence is suitable for medical applications.
- Melting point 175 °C., and glass transition temperature 2 °C.
- Tensile strength 40 MPa, close to that of polypropylene.
- Sinks in water (while polypropylene floats), facilitating its anaerobic biodegradation in sediments"
  - Find what PLA does
