Biodegradable plastics are an alternative to conventional plastics that are chemically synthesized and are responsible for causing environmental pollution due to unwanted accumulation occurring via disposal practices. There was a serious need to introduce biodegradable plastics in the market since the level of plastic pollution in the air, water, and soil has reached its threshold values. The non-biodegradable plastics are increasingly accumulating in the environment, which can be a threat to the planet in the coming future. This chapter provides detailed insight into biodegradables polymers, mostly aliphatic polyesters that are considered as a solution against synthetic plastic. It also gives brief information on the current scenario of plastic biodegradation, recent advancements, opportunities, and future challenges. Also, it comprises precise strategies currently used at a laboratory scale to enhance biodegradation of classical synthetic plastics (e.g., polyethylene, polystyrene, etc.). Moreover, the factors affecting the biodegradation process and the characterization techniques being employed to assess degradation extent are also discussed. The overall work focuses on thrust areas to be improved concerning environmental safety and sustainable vision.","PeriodicalId":222901,"journal":{"name":"Degradation of Plastics","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124459101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bhange","doi":"10.21741/9781644901335-2","DOIUrl":"https://doi.org/10.21741/9781644901335-2","url":null,"abstract":"Fossil oil prices are soaring steeply due to the depleting petroleum raw materials. Extensive research has been carried out around the globe to develop efficient processes that can replace oil-derived polymers (conventional plastic) with bio-based polymers that originate from renewable resources. Fossil-oil based plastic products take decades to degrade, leading to the unwanted accumulation of plastic waste that can be seen all around. Further, greenhouse gases emission occurs during the production and destruction of synthetic plastic. Therefore, plastic waste has become a massive threat to the biosphere and needs to be addressed immediately. To overcome this issue, a new type of plastic can be produced from bio-resources that can fulfill even the energy demand in today's world. This new form of plastic must be accommodated fast in daily life, considering the range of applications of plastics. Biodegradable plastics made from renewable raw materials can retain all the benefits of petroleum-based plastic without having any negative impacts on the environment. Bioplastics are not toxic in nature and can easily decay back into carbon dioxide via degradation. The products made from bioplastics may be commercialized, considering their superior properties over conventional plastic. The discovery and implementation of plastic made from renewable raw material resources could be a giant leap into the sustainable future.","PeriodicalId":222901,"journal":{"name":"Degradation of Plastics","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116264287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
