摘要

2005年至2014年间,全球人均塑料使用量增长了约25%,而孟加拉国的人均塑料使用量增长了16.2%。2019年的一项调查发现,孟加拉国每年处理8.7万吨一次性塑料,其中约96%来自食品和个人护理产品的包装。此外,在SARS-CoV-2大流行期间,在个人防护装备中广泛使用大多数不可生物降解的一次性塑料,导致它们在垃圾填埋场和周围环境中堆积。此外,近年来,该国气候引发的洪水事件加剧了宏观和微观塑料污染,这些污染源于救援物资包装材料中塑料废物的管理不善。此外,在RCP 4.5情景下,2040年和2060年的预测降雨情景表明,洪水风险加剧,这可能会影响塑料污染。通过系统的文献综述和实地考察相结合,本研究评估了孟加拉国使用的塑料废物管理策略,确定了研究空白,并提供了对该国塑料回收的见解,特别强调了孟加拉国首都达卡。研究结果表明,在循环经济中整合塑料回收系统有望减少温室气体排放和环境污染,同时促进若干联合国可持续发展目标。

Bangladesh Plastic Consumption Trend: Current Scenario

Between 2005 and 2014, per capita plastic usage increased by approximately 25% worldwide whereas in Bangladesh, it increased by 16.2%. A 2019 survey found that annually, Bangladeshis disposed of 87,000 tons of single-use plastics, approximately 96% of which originates from food and personal care products packaging. Additionally, during the SARS-CoV-2 pandemic, the widespread usage of mostly non-biodegradable single-use plastics in personal protective equipment resulted in their accumulation in landfills and the surrounding environment. In addition, in recent years, climate-induced flooding events in the country exacerbated macro- and microplastic pollution stemming from the mismanaged plastic waste from relief supplies packaging materials. Moreover, projected rainfall scenario for 2040 and 2060 under RCP 4.5 scenario suggest exacerbated risks of flooding, which will likely impact plastic pollution. Through a combination of a systematic literature review and field, the present study assesses the plastic waste management strategies used in Bangladesh, identifies research gaps and offers insight into plastic recycling in the nation, with a particular emphasis on Dhaka, the capital city of Bangladesh. The findings indicate that integrating plastic recycling systems within a circular economy is anticipated to lower greenhouse gas emissions and environmental pollution while promoting several UN Sustainable Development Goals.

期刊介绍: Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
