“…In particular, polylactic acid (PLA) is noted as the most promising material in the bio-plastic sector. Since PLA has properties comparable to those of polystyrene (PS) and polyethylene terephthalate (PET), it can replace these petroleum-based plastics for a wide range of applications [4,5]. In the global market of bio-plastics, the biodegradable polymers market is expected to grow to 5324.4 million dollars by 2021 [6].…”

Bio-plastics such as polylactic acid (PLA) have been investigated as a sustainable alternative to petroleum-based plastics. In this study, the carbon footprint of packaging films made from LDPE, PLA, and PLA/PBAT blends was measured with three different waste scenarios based on the database of South Korea using life cycle assessment (LCA). The LCA followed ISO standards, and was a cradle-to-grave analysis. The functional unit was defined as 400,000 pieces of a film of 300 × 250 mm with thickness of 0.06 mm for packaging bag manufacturing. The waste treatments considered were incineration, landfill, and recycling applied with the present conditions of South Korea. Under the present analysis conditions, the PLA film with landfill was the most effective for reducing carbon emission. The PLA/PBAT with incineration was the worst case among the packaging films tested. Incineration was the worst choice of waste treatment in terms of carbon dioxide emissions. Generally, landfill may not be the best option in terms of sustainability but landfill was a better option for waste treatment than incineration. In addition, before bio-plastics are blended with other material, the blending material should first be evaluated for its environmental impact. The blended bio-plastics with PLA, such as PLA/PBAT, can be more inimical to the environment in terms of carbon dioxide emissions than existing materials, such as LDPE.

“…This is because of the worldwide concern associated with the accumulation of plastics waste in the environment. In this context, thermoplastic starch (TPS) and poly(lactic acid) (PLA) blends have received attention as promising bio‐based materials for the production of compostable artifacts . As many other immiscible blends, they need to be compatibilized, to overcome the unfavorable entropy of mixture.…”

Tuning the mechanical and electrical conductivity properties of graphene‐based thermoplastic starch/poly(lactic acid) hybrids

2018

Environmentally friendly approaches were followed to develop thermoplastic starch (TPS)/poly(lactic acid) (PLA) extruded hybrids at 70:30 and 30:70 compositions, with the incorporation of reduced graphene oxide at 1.0, 3.0, and 5.0 mass% contents. Glucose was chosen as reagent to reduce graphene oxide (GO) to the rGO sample. Theoretical models predicted that the final location of rGO was at the interface of the components. The adhesion between the polymeric phases in the hybrids, observed by scanning electron microscopy, and the improved compatibilization suggested by mechanical and dynamic mechanical analyses indicated that a large fraction of rGO platelets were at the interface. X‐ray diffraction showed that rGO acted as a nucleating agent for PLA and revealed a better dispersion of rGO lamellae within TPS. Consequently, the phase composition of the TPS/PLA/rGO hybrids played an important role on the properties of the hybrids. For the neat TPS/PLA blend at 70:30 composition, ɛmax = (4.7 ± 0.6)% and the electrical conductivity was found around 10−13 S/cm. The incorporation of rGO led to more flexible and to higher conductivity materials, with ɛmax = (15.1 ± 0.7)% and σ = 1.1 × 10−5 S/cm for the hybrid with rGO at 5.0 mass% content. POLYM.

“…This concept takes into account measures to determine the quantities of used materials, energy and waste generated at each process (starting with raw material extraction, through manufacturing, distribution, use and reuse/ recycling, to final disposal) (Benetto, Jury, Igos, Carton, Hild, Vergne, Di Martino, 2015). A particular stage in the design and development of a new product with the use of the Eco design approach is screening.…”

The purpose of this article is to define the role of environmental management in the implementation of the concept of a Green Sustainable Supply Chain. Widespread interest in the implementation of this concept determines the environmental activities which are undertaken by companies. For this reason, more and more organizations are interested in the introduction of an environmental management system (based on the requirements of the ISO 14000 family of standards). The involvement of companies in the implementation of the concept of sustainable development is also reflected in the propagation of this idea among business partners in the supply chain. Undertaking activities mitigating the negative impact on the environment is considered by many organizations an important criterion in the initial and periodic assessment of suppliers. Many companies, while working on developing of a strong and positive brand image among their customers, use environmental labels when promoting their products. In recent years, more and more companies implement the material flow cost accounting concept which takes into consideration the relationships in the supply chain.
