“…Over 20 bacterial genera can degrade PE such as Pseudomonas, Ralstonia, Stenotrophomonas, Klebsiella and Acinetobactor [76]. Fungi were thought to be more efficient than bacteria for the degradation of PE because they can attach to the hydrophobic surface of the polymers [77]. Fungal laccases and peroxidases, generally used by fungi to degrade lignin, showed high efficiency in degrading PE and PVC.…”

Plastics are an essential component of modern life, but the plastic waste has caused significant environmental pollution and economic losses. The effective solution to these problems is the biodegradation and high-value conversion of plastic waste. After biodegradation, plastic waste is broken into smaller molecules and eventually transformed into innocuous substances like water, carbon dioxide and biomass. High-value conversion enables plastic waste to be converted into products with higher economic value and environmental friendliness. Based on this, we summarize the biodegradation methods of bioplastics and analyze the shortage of these methods. Subsequently, we summarize the progress of converting the degradation products into value-added chemicals, comprehensively analyze the advantages and disadvantages of these bioconversion process, and propose some strategies to address these disadvantages. Finally, we analyze the significance of establishing a microbial-based conversion process that integrates the degradation and the conversion, and propose some potential strategies.

“…The most communal synthetic polymers are polypropylene (PP); polyethylene (PE), polystyrene (PS), polyethylene terephthalate (PET), polyvinyl chloride (PVC) and polyurethane (PU, PUR) and the most consumed synthetic polymer is PE. [3][4][5] These materials exhibit various properties such as stability, durability, low cost, high elasticity, robustness, light-weight and tensile strength. 6,7 Owing to the outstanding properties, plastics are widely used product in many areas of daily life and industry worldwide.…”

Millions of tons of chemical plastics are accumulated annually worldwide in terrestrial and marine environments due to inadequate recycling plants and facilities and low circular use. Their continuous accumulation and contamination of soil and water pose a severe threat to the environment and to human, animal and plant health. There is therefore an urgent need to develop effective eco-environmental strategies to overcome the significant environmental impacts of traditional plastic waste management practises (incineration, landfilling, and recycling). In recent years, reports on microbial strains equipped with the potential of degrading plastic materials, which can further be converted into usable products such as PHA bioplastics have sprung up, and these offer a possibility to develop microbial and enzymatic technologies for plastic waste treatment and then progressing plastics circularity. In this chapter, an overview of the reported microbial and enzymatic degradations of petroleum-based synthetic plastics, specifically polyethylene, polystyrene, polypropylene, polyvinyl chloride, polyurethane and polyethylene terephthalate, is detailed. Furthermore, the harvesting of depolymerization products to produce new PHA materials with high added industrial value can be considered as an innovative solution, helping to increase synthetic plastic recycling rate and creating new circular economy opportunities. Finally, the challenge of ending plastic pollution is still difficult, but sustainable, renewable, bio-based and completely biodegradable, PHA will hold enormous promise for replacing plastics made from petrochemicals.

“…ASA가 외부 환경(자외선, 수분 등)에 의해 변색되거나 소재 특성의 변화에 견디는 성질이 강하고, PVC(Polyeinyl chloride)의 경우 소재도 가볍고 변화가 가능해서 악기 제작 에 많이 사용되고 있는 편이다(Seo & Yeom, 2023).음악교과서를 보면 오케스트라악기와 국악기(단소와 소고 제외)보다 교실악기로 명명 할 수 있는 악기들 중에서 리코더, 멜로디언, 템버린, 에그쉐이커, 붐웨커가 플라스틱 재질의 악기로 기악수업에서 많이 활용되고 있다. 악기연주하기 활동에서 리코더의 경우 플라스틱 대신 나무재질 악기를 사용하거나 최근 새롭게 개발되고 있는 CXP(Cellulose Cross-linked Polymer) 2) 라는 임업부산물을 통한 악기 제작으로 대체할 수 있을 것으로 본 다.…”

The purpose of this study is to find plastic instruments used in music curriculum and provide alternative instruments, which are the cause of environmental pollution. For this purpose, the plastic instruments used in 72 music textbooks published from the 1st to the 2015 revised curriculum were organized and analyzed. As a result of this study, first, plastic recorder and melodica(melodion) were used for the first time in music textbooks applied to the 2nd curriculum(1963-1973). Second, plastic instruments such as recorder, melodion, tambourine, sogo drum, egg shakers, and boomwhackers were found in music textbooks. Lastly, the number of musical instruments made of plastic has increased slightly in authorized music textbooks. For ecological sustainability, it is necessary to reduce the use of plastic instruments in music textbooks and provide instruments made of eco-friendly materials and wood.
