(BDO) (Xu and Guo 2010; Bhatia et al. 2012). PBS can be manufactured fully or partially from renewable resources (Xu and Guo 2010), even though currently it is polymerized partially fossil based monomers in the industrial scale (Yim et al. 2011). The major steps for PBS production are included in Fig. 4. Renewable succinic acid is manufactured by bacterial fermentation. Possible raw materials include, for example starch, glucose, xylose (Xu and Guo 2010), or agricultural waste (McKinlay et al. 2007). By similar means, renewable BDO can be produced via the fermentation of sugars (Harmsen et al. 2014). Currently, the prevalent production method of BDO is still from oil-based feedstocks (Yim et al. 2011).

Block diagram to illustrate the production of biobarriers from biomass fermentation (see Burk 2010; Chen 2010; Xu and Guo 2010) The PBS exhibits good mechanical strength, great processability with traditional polyolefin processing equipment (Wang et al. 2013), high elasticity and a reasonably high thermal and chemical resistance (Lin et al. 2011; Bhatia et al. 2012; Phua et al. 2012). In addition to biodegradability in soil and aquatic environments, PBS is also
