There are a number of advantages to the use of plant oils for
PHAs production. Global production of these oils is still increasing,
which could make them major sources of agricultural feedstocks in
the future. Because these oil crops can be grown in any warm or
temperate region of the world, this process would be geopolitically
independent. In addition, usingwaste oils for PHA production helps
reduce the costs and problems associated with disposal of these
oils. Bioconversion of wastes like these into valuable products like
polyhydroxyalkanoates is one of the most attractive aspects of the
emerging global bio-economy. Using waste oils to produce PHAs
can diversify incomes in the agricultural sector by allowing it to
deliver plant oils to the biotechnology market. In order to realize
these advantages, a number of things must be determined, such as
the proper proportions of ingredients, storage issues, and the reliability
of rawmaterials. An important factor could be the amount of
available waste oils. In addition, transporting these oils over long
distances might be problematic and costly.
