Biodegradation in soil effects on PLA/sisal and PHBV/sisal biocomposites

The use of bio-based composites like lignocellulosic fibres/polymer composites as an alternative materials are continuously increasing in several applications such as automobile manufacturing, packaging, construction or household and agricultural equipments. In order to warranty the durability on green biocomposites based on polymer matrixes like poly(hydroxy butyrate-co-valerate) (PHBV) and poly(lactide) (PLA), the previous knowledge about the influence of the ambient agents on their macromolecular properties is necessary. In this sense, biodegradation in soil normalised experiments are useful. In this work, two commercial PHBV and PLA were reinforced with sisal fibres at 10 %, 20% and 30%…
