“…The temperature of the compost in real composting was 40 ± 1 °C (lower than the glass transition temperature), which probably led to the slower rate of biodegradation of the composites. Similarly, Bayerl et al [26], Neppalli et al [32] and Petinakis et al [33] reported that virgin PLA has a very slow breakdown compared to natural fiber-reinforced composites. According to Bayerl et al [26], the architecture of fiber structure in a PLA composite can influence the degradation behavior of the composite.…”

“…This material was obtained in an incomplete decayed state and consisted mainly of plant and waste. Fresh green waste, such as grass clippings and twigs, was incorporated into the intermediate state compost to keep the decaying process going [26].…”

“…The moisture content of the compost was measured daily using a moisture analyzer (Sartorius Moisture Analyzer Model MA35, Sartorius AG, Goettingen, Germany). The pH value was regularly monitored and kept around the neutral pH value of 7, which is considered ideal for bacterial growth [26]. Initially, compost was added on the compost pile, and later, the specimens in the organza bag were placed on it and completely covered with compost.…”

The present study was conducted to determine the recyclability and biodegradability of bamboo fabric-reinforced poly(lactic) acid (BF-PLA) composites for sustainable packaging. BF-PLA composite was recycled through the granulation, extrusion, pelletization and injection processes. Subsequently, mechanical properties (tensile, flexural and impact strength), thermal stability and the morphological appearance of recycled BF-PLA composites were determined and compared to BF-PLA composite (initial materials) and virgin PLA. It was observed that the BF-PLA composites had the adequate mechanical rigidity and thermal stability to be recycled and reused. Moreover, the biodegradability of BF-PLA composite was evaluated in controlled and real composting conditions, and the rate of biodegradability of BF-PLA composites was compared to the virgin PLA. Morphological and thermal characteristics of the biodegradable BF-PLA and virgin PLA were obtained by using environment scanning electron microscopy (ESEM) and differential scanning calorimetry (DSC), respectively. The first order decay rate was found to be 0.0278 and 0.0151 day´1 in a controlled composting condition and 0.0008 and 0.0009 day´1 in Polymers 2015, 7 1477 real composting conditions for virgin PLA and BF-PLA composite, respectively. Results indicate that the reinforcement of bamboo fabric in PLA matrix minimizes the degradation rate of BF-PLA composite. Thus, BF-PLA composite has the potential to be used in product packaging for providing sustainable packaging.

This paper describes the flexural properties of biodegradable composites made using natural fiber and biodegradable plastics. Biodegradable composites were fabricated from bamboo fiber bundles and PLA (polylactic acid) resin. In this research, effect of molding temperature and fiber content on flexural properties of bamboo fiber reinforced composites was investigated. The flexural strength of this composite increased with increasing fiber content up to 70%. The flexural strength of composites decreased at molding temperature of 180˚C. Biodegradable composites possessed extremely high flexural strength of 273 MPa, in the case of molding temperature of 160˚C and fiber content of 70%.
