PHA biosynthesis, recovery, and application: A circular value chain for production of self-healing concrete from waste

Polyhydroxyalkanoates (PHA) are a family of biopolymers produced intracellular<br/>by a range of different bacteria.PHA have attracted widespread attention as<br/>an environmental friendly replacement of fossil-based polymers, because they<br/>have thermoplastic and/or elastomeric properties, and are also biobased and<br/>biodegradable.Moreover,...

From waste to self-healing concrete: A proof-of-concept of a new application for polyhydroxyalkanoate

Polyhydroxyalkanoate (PHA) production is a promising opportunity to recover organic carbon from waste streams. However, widespread application of waste-derived PHA as biodegradable plastic is restricted by expensive purification steps, high quality requirements, and a fierce competition with the conventional plastic market. To overcome these...
